50 State Legal Performance??

[82mustangGT]

I live in Ca and I am looking to do some performance mods on an 82 GT.What all can be done to it?Id like a true dual exhaust with an X/H pipe,Intake Manifold and carb,and headers.I havent seen any headers that are 50-state legal.I'm also hoping to do a t-s swap soon because the SROD is no good for me lol.
Thanks,
Philip

[Wolfie351]

JBA has legal headers for 79-85 carbed Mustangs. Most aftermarket heads are also legal for Fox Mustangs, carbed or EFI. But, neither will do much good with your 2bbl. You might be able to get by a smog tech by using 83/85 carb & intake, but that won't be truly legal unless you went to a smog referee to get it certified for that later model year. But, if you're going through the trouble of getting it certified, you might as well swap in an EFI setup.

[82mustangGT]

Ok, thanks.So is the Carbed engine not really worth messing with as is?Do you think a smog-tach would notice the diff manifold? I think saw that Edelbrock has a manifold for the 83(i think,not completely sure tho).What about a cam?I really want to tune this thing up to back up its looks.Because 16 sec quarter isnt impressive lol.How much would the t-5 help?Throw any suggestions you have at me.What about the exhaust?Will it always have to be routed int oa y or can it be made into a dual?

Thanks,
Philip

[v8only]

You can legally do whatever ford offered. I don't remember if ford had a 4bbl carb or not in 82. If they did, then you can legally update to the 4 bbl setup.

technically, you'll be changine the # of cats on your system by updating to 86+ dual exhaust. ALthough you're increasing the # of cats, that won't matter, it's technically not allowed. However, a proper oem 86+ dual exhaust conversion may go completely un noticed by all.

Technically, the best thing to do is swap in a later motor, which IS legal. BY LAW, if you swap a newer engine into your car, you MUST retain ALL of the emission components. Therefore, swap in an 87-93 5.0 engine. You'll be required to retain the efi, AND the true dual exhaust setup. it's a bit of work, but it'll bump your game up by miles and open the door to almost unlimited smog legal mods.

[82mustangGT]

Well Ford didnt have a 4-brl,I know that for a fact.Well it looks like I'll just stick with the 82 engine for now,Until I have the time to do a swap,which probably wont be until Christmas Vacation.Oh well,Atleast I'll have time to start gathering parts.How long woulda an EFI engine swap take if you had all of theparts?I get 2 weeks off for Christmas.
Thanks,

[anthonydalrymple]

Whoops.... dang double post got me once again..... :roll:

[anthonydalrymple]

I'd swap in a complete 88(Cali only)-90 mass air motor. Engine wiring harness, O2 harness, EEC, etc. Rebuild the motor & go. It'll be 100% legal & the 4-cat dual exhaust as well. Best method is to find a formerly running LX or GT that's been in an accident to buy.

Slowly, swap everything over including the aero-nose.. 8) <J\K!>

Seriously tho.... you get an 8.8 out of the deal to swap over too. The engine bone stock will have more power & be more docile than the origional carb'd engine. Then..... You can start doing all the mod's for even more power :D

[82mustangGT]

I noticed what you had on your engine.Does it actually pass smog when you put the cats back on?Or is this a race only car?Know of any Clubs in So. cal that are dedicated to four eyes?
Thanks

[v8only]

Lol, no specific four eyed clubs, but you need to check out the events section here. I/we regulary post up hang outs in so cal.

2 weeks is a tight sched, but if you've got a lot of beer, and a couple of friends, it's very realistic. I agree with Tony, grab a parts car. You have a BUNCH of choices. Scout recyler.com, and wait till a parts car comes up. You shouldn't have any problems locating one for a grand or less.

[fordfreak300]

the smog techs won't give you any trouble with a 4 barel carb as long as it is a 4180 or looks like it. You can also put on an 86 or newer exhaust system and be fine. The only smogable 4 barrel manifold is the performer 302 because it has EGR provisions. Put that manifold on. Goto a junk yard and find a stock 4180 carb on a car and pull it off. Next Get a holley 600 vacume secondary carb. (4160) Put the bowls from the 4180 onto the 4160 and it looks the same. I have a 91 motor in my car. I have never told a smog tech that. Only one smog tech has ever noticed my equal length headers. Only reason he noticed them was I knew the guy and he wanted to see what my car really had. The performer 302 manifold has a carb EO number. There by letting yu use it. It just so happens to be a 4 barrel manifold. Most smog techs won't bother checking if they see the 4180 bowls that say ford made by holley on them. Looks stock to them they are happy. You have to remember they see mostly newer foxes with EFI so they over look some of the simple things. They won't even notice an 86 or newer Stock Hpipe allowing true duel exhaust. But before i go sugesting performance mods I would really like to know how you plan to use the car?

Why stop at '90?

[82mustangGT]

I would like the car to be"streetable" obviously.My school and Work are only 2 miles away from my house.But I need to drive 260miles roundtrip on the freeway once a month.What kind of performance could I expect to get out of this car?Will it ever be able to compete with an EFI model?I'd prefer to keep it carbed.
Thanks,

Philipa carb can do well in HP, but not as well as an EFI in mileage.

Technically, my car is 100% smog legal & the engine is "fresh" enough that it should pass easily. The only concern i have is with the mild custom cam i had made... All the numbers for lift & lobe sepperation are good; but it has alot of durration which might get me into trouble. I'll find out come this May... ;)

It's my 75 mile a day plus commuter; so it's plenty streetable. Once you start modding a mass air motor; a Diablo chip being burned just for that particular combo works wonders for keeping it very streetable....

I'm biased....;) 88-93 will do just fine....

[82mustangGT]

Ok.So should I just wait and swap in an EFI?I would really prefer to keep it carbed.But I havent seen any Street legal cams for a non-roller block.I e-mailed Edelbrock to see what they say,which I'm sure will be a "NO".

I am getting 23 mpg with my carbed set up, what are you getting?

[82mustangGT]

All Edelbrock said they have is an Intake.Would it matter if i got a 4v version?They have a 2v version and a 4v version.So this Coupled with JBA Headers.Is there a Catback system that i can get for this?Would this car be pretty respectable with whats listed and a t-5?What about some twisted wedge heads?

You can put in a newer roller motor and put a carbed manifold and carb on it. I knwo because I have done so. I have a 91 motor in my 84 stang. There are also kits out there to convert your block over to roller motor but it will take some work. If yuo want to stay carbed then by all means do so. By the time you swap over to EFI yuo could have already modded your current motor and had more HP. (for those that are goign to read that statement wrong, he will have to buy the roller motor and all the efi stuff vs staying carbed and nto having to buy it) There cams out there for flat tapet motors. Just check out comp cams, crane and a few others. They are out there. Just do some searching.

You can put the 4v intake on. I live out in yucca valley. I'll have to show you my car sometime. For the catback I would get a stock H pipe for now and stock tailpipes. Then yu can get an offroad H pipe for later down the road. You will need the stock H pipe for passing smog.

[82mustangGT]

So i should go pull the h-pipe off of a later model car?Will it still pass smog becasue originally it had the single?

He legally cannot put a 4bbl carb on that 82. 82's came with a 2 bbl carb. However... he can toss an edelbrock performer EGR intake on it and buy the 4bbl to 2bbl adaptor. He can used the 4bbl between smogs and swap the 2bbl with the adaptor on for smoging. He wont beable to getaway with the dual exhaust since it's an 82 unless he converts to 86+. He can do JBA's and 2 1/2" Duals to a 3" single and get away with it legally and still get that thing pushing out stock 210 or more hp(with the 4bbl on between smogs). The 2 1/2" duals to 3" single seems to be good for upto nearly 300rwhp... going by LTDScotts SVT LTD. The JBA's are legal for ford passenger cars with the 5L from 79+. I was going to toss these on my 79 Futura.

If he wants to go the illegal way to pass it he can... but he will be taking a chance. It's better off that he either convert it all totally over to 86+ or do what he can get away with in 82 standards.

There is also a chance that he could change it legally over to an 85 GT 4bbl 5spd... but he will not be able to get the true duals past the ref's. He would need to do the 85 style speudo-dual exhaust Then after it's approved he could swap on an H-pipe. Though, even then... theres a chance he could get caught with the H-pipe.

There are many possiblilities depending on what he wants do do.

[82mustangGT]

Can I put a high-flow cat on it too?I think I need to go to an Exhaust shop and explain what I want to do and see what they say..So I go 2 1/2in off of the headers to the Y and then from the cat back put a 3 in?What kind of muffler would be best?I really appreciate all of your guys help with my dumb Q's.
Thanks,
Philip

[anthonydalrymple]

Keep in mind that you can put on a four cat' h-pipe & dual exhaust. You just have to swap over the rest of the emmissions system for that given year as well. CARB has an issue with swapping in motor's before your vehicle year & removing emmisions equiptment; but they have no issue with swapping in later year motor combinations. The later mustang combo must include all the proper smog equiptment for that given year, the four cat h-pipe is part of that years emissions "devises", & pretty much that's all there is too it! A mass air roller motor conversion is perfectly legal... My notch was a 4cyl\auto once....

I would much rather do a mass air motor swap simply because the "carb" size, jetting, intake manifold selection, exhaust manifold selection, dual exhaust conversion,etc no longer are an issue....

[82mustangGT]

Well I ve just started working so I'm going to start saving up and I think I'll probably do an engine swap.So any year from 86-93 will do?Atleast that way I could do the engine and trans and rear end all at once.And it seems that theres way more perofrmance Items for the EFI models.I'd like to have a 13sec streetable car.And stock I believe its a 16.6sec car so theres alot of improvement to be made.
Thanks,
Philip

[anthonydalrymple]

You probably should stay away from the speed density years for a couple of minor reasons if you plan on going mass air eventually...

The speed density E6 heads are not as desireable as the E7 heads common on the mass 88-93 Caifornia Mustangs. You might think you will just swap the heads later on; but you might have to notch the pistons for valve clearance. I know; I built an '86 roller motor this year & had to notch the pistons .010 to clear the E7 valves. Secondly, the later year mass air motors are a "dime a dozen" in the junkyards. Often on all of the southern Cali Mustang forums; people give away the mass air stuff for free since thier converting to the "performance" stuff. Keep an eye on these forums.....

[fordfreak300]

if that is the case, then why do I keep passing smog with my 84 that has duel exhaust??? hmmm think about that guys... headers with a carb eo number and an intake with a carb eo number. Once they see that they leave the rest alone. You just have to pull teh emissions sticker off your hood so they can't see it. Once they start seeing carb eo numbers for everything they leave it alone for the most part. And if you have a factory 4 barrel carb on there then your fine. I don't even have a carb EO number on my headers they are not 50 state legal and yet I pass smog every time. if yu keep all teh greese and grime out of your engine bay and keep it nice looking and have carb eo numbers they usually won't mess with you. I always go in sign up for my smog and hand them my keys. Then i go back out and start my car and sit in it with teh door open. When i see them comming for my car I turn it off and follow the guy as he drives my car around the enterance into the test area. I stand there and watch and small talk with the guy.

My 84 has true duels and has no problems passing. If yuo read my post above I have no Carb EO numbers on my BBK equal length shorties.

[fordfreak300]

You all are making it sound harder than it really is to this kid. Most smog techs don;t even see enough four eyes to realize they are supposed to only have one tail pipe. They think of it as a mustang so it should have duel exhaust and a 4 barrel. Smog techs make money per car they want yrou car in and out. If you make things look good it will pass the visual. Just have the carb EO numbers for the obvious. Like intake and headers. Once they see that they are good. I have all my MSD carb numbers placed right on the rad support and they look there and never even ask me any questions. I am even missing half my smog system :)

If your passing with true duals on an 84 then your going to smog techs that don't know any better. Who knows... you may get that ONE guy one day that knows about FOXes and that your 84 originally didnt' come with true duals. Then you'll be in deep and have to change it right back over to single exhaust AND take it to the CHP ref to get it to pass again.

I Feel that I'm taking a risk with my 85 GT and its 86+ true duals and it came with duals... even though it wasn't true duals. And as said... most techs don't know about them and think that all V8 Mustangs may have had true duals... so they don't even think about it when they look over a car.

When I had my GT smoged when I first bought it the test only shop that I go to just opend the hood... laughed, backed it up onto the dyno and ran it. They didn't look at ANYTHING on the car... no cat check, no timming check, no gas cap check and no anything else I may have left out. But with both of the completely factory V8 Fairmonts and the LTD LX that I've had (and have) they'ed give the third degree. The Fairmonts and the LTD were (and are) in great condition. This is the same shop I have all my cars smogged at.

Trust me man... you (and I) are taking a chance. Some smog tech may just know what these cars came with and know that the 85 and down Mustangs didn't have an H-pipe... let alone 4 cats.

According to California law... you can drop any passenger car engine into your car as long as it is from your year car and up. You also need to swap over the whole emmisions system from that donor car. If you keep your car smogged as an 82 (or 84 with FordFreak and 85 as mine)... you cannot have more cats than what the car had originally come with. That is Cali law and we are breaking it. If we are cought... they will report the car as tampered with... will not pass you... will make you fix it and you will have to get the SMOG REF at the CHP test staion see it and pass it.

Granted... they are not truely going to know what year engine you really droped in. My LTD LX has a 1991 Mustang SB in it... do they know? Do they check the engine SN? No. 302's look alike from the out side.. they can't tell worth beans.

Just know that your getting into and what can happen if you run into a Smog tech that knows his stuff and is in a bad mood.

jasen

[82mustangGT]

I really aprreciate all of your help on this.I'll probably just end up doing the EFI swap later on,but for now I'll just keep it stock and get the body in order(Peeling paint and Accident damage).Then once it looks good,I'll dive into the engine aspect.I've been reading that a stroker can pass emissions too.So maybe its time for a build-up.
Thanks,
Philip

[fordfreak300]

With most techs if you dont; say anything they won't know the difference. My uncle put EFI on his 84 and they havn;t picked up on it is supposed to have a carb yet. Been a few years too. he has carb EO numbers for ak the aftermarket EFI stuff in the same spot I do. They never said anything about his true duels either. They worry more about aftermarket parts and smog parts missing than they do if yuo changed something that a later year had with in close reason. They overlook that 6 year period our cars were built and group them in with the later cars.

[Wolfie351]

I've had my '85 for almost 20 years and it has always been listed as "dual exhaust" on my smog test, wether it had a Y pipe or it's current H pipe.

[Marz]

I've had my '85 for almost 20 years and it has always been listed as "dual exhaust" on my smog test, wether it had a Y pipe or it's current H pipe.

Yes... it's listed as having duals because it came with duals... just not true duals. Wether or not it has an h-pipe or two y-pipes (speudo duals)... it wouldn't matter to them (kinda). The cats are what matters to them. And because of this... whether or not you have the factory Speudo duals or the 86+ True duals would indeed matter to them. 85 Mustangs did not come with four cats. For our 85's... having four cats is illegal. Originally the 85 Mustangs either came with one or two cats (don't remember which right now). The cats are a sure way to fail you while smoging if the Tech knows what the car had originally come with.

I seem to be repeating myself here... Read my previos posts FULLY and you all will (hopefully) understand what I'm talking about. And what I'm telling you is what the Cali LAW says you can do. And ofcorse, if you do mod the car slightly off of stock (cali govies don't want you to do this BTW)... like with tossing a H-pipe on a 85 that had speudo duals from the factory... you are taking a chance with the Smog tech knowing, not nowing... or not even careing about it. And if the smog tech knows about it and CARES about it... he is legally bound to fail the car and report you to protect his own rear or he'll loose his licence. NOw if the smog tech knows you and knows you are not an undercover cali-smog-nazi spy... he may let you slide on some things.

My 79 Futura had come with the V8 and Variable "nightmare" Venturi (VV)carb. I tossed that VV and tossed a more reliable 2100 series 2bbl on it. I didn't tell the smog guys jack about it and they knew that carb wasn't factory... even though they didn't care and the car passed... they still mentioned it to me. Basically... they knew that since the Futura was a cali car... it had to have a VV 2bbl carb on it... not the 49 state 2100 series 2bbl.

[FoxChassis]

Originally the 85 Mustangs either came with one or two cats (don't remember which right now).
As with previous model years, the CFI-equipped model and the carburetor-equipped model had a single converter.

85 carbed cars had two cats. 1 small one and 1 large one.

I'm pretty sure on this since I crushed my exhaust system in the accident and when we replaced it, I couldn't find another YPipe, so we had one fabricated and the guy wasn't able to make a provision for the small cat and just put a new large cat back on.

[82mustangGT]

ok,So IF I decide to stay carbed I could get the Edelbrock Manifold and just put the 2-brl on for smogging.Are there any heads I can get that are smog legal for an 82 and would run good with the stock cam and Pistons?

Hmmm....

http://www.geocities.com/mt83rd/85_AOD_exhaust.html

That comes straight from FoMoCo's very own parts system.

(Yes, it says "AOD" - which also mean CFI - but that is the same configuration as the 4V.)

[anthonydalrymple]

Where are you getting this information from? The california CARB law states that if you convert your (for example '85 Mustang) to a '93 mass air motor; you must include the '93 full emissions equiptent as well. That means the four cat h-pipe will now be required & your car also now will be required to meet the appropriate '93 emmissions compliance. It is illegal to just swap on a true dual exhaust without cats or just leaving the origional cat in one pipe. But there is not law stating you cannot have four cat's.... Providing a link to your info would be greatly appreciated!

Well it so happens I have a nearly new 1985 GT 4v takeoff exhaust in my attic. I will take a pic and refresh both our memories. I believe it had the extra cat on it. I planned on swapping it in to my car someday. It has the infamous YPipe so I believe what the seller was telling me was true....that it was from an 85GT with 4v.

yes phillip you can do the edlebrock manifold and put a 2 barrel to 4 barrel adapter on to pass emissions.

*sigh*

I basically said that.. but using my 85 for an example! I also did not state that the 85 was converted to 86+ EFI... it's assumed that the 85 Mustang is being kept as a 4bbl ... like mine... which has the factory 4bbl with a 86+ 4 cat h-pipe... which is not legal for an 85!

Having a 86+ h-pipe is illegal for an 85 Mustang... which came with less cats than the 86+!

Yes, if you were to convert that 85 Mustang to 86+ EFI then you would need all the imissions equipment from said year of converion in cluding the 4 cats. Corse... there also an acceptable two cat imissions legal h-pipe that has two of the 3 way cats on it... which act like a four cat h-pipe set up for the 86+ Mustangs.

[Marz]

ok,So IF I decide to stay carbed I could get the Edelbrock Manifold and just put the 2-brl on for smogging.Are there any heads I can get that are smog legal for an 82 and would run good with the stock cam and Pistons?

E7 heads would work fine... Better flow than the stock 82 heads and slightly more compresion.

DeanT had the 78 302 from his 78 Futura rebuilt with a slightly hotter than stock cam (for more torque) with a pair of E7 heads tossed on it... and is now in his 78 Fairmont wagon. This engine has the Edelbrock 4bbl intake with the 4bbl to 2bbl adaptor and a 2100 series carb on it. Due to the 4bbl to 2bbl adaptor he could not use the 82 Mustang tall style air cleaner lid because of hood clearance issues. He tossed the factory air cleaner lid back on. If you do the Edelbrock set up and the stock taller 82 Mustang air cleaner lid rubs against the underside of the hood... you can get away with using the Fairmont shorter style air cleaner lid( along with the fairmont element). Or possibly just update the whole air cleaner assembly to the later larger diameter (and shorter air cleaner lid) dual snorkle air cleaner assembly. I think the 4bbl version should fit on the 2bbl carb.... but not sure.

Glad I'm living inthe middle of nowhere!!!

They can pry my off road h-pipe outa my cold dead hands!
lol
Not likely my county will do smog checks anytime in the future.

I feel for you guys!

Corse... there also an acceptable two cat emissions legal h-pipe that has two of the 3 way cats on it... which act like a four cat h-pipe set up for the 86+ Mustangs.

Yep, I have that smog legal Magnaflow stainless 2-cat x-pipe on my car right now....;)

Sorry, I am most definetly not trying to start anything nor "shooting you down". There are many ways for Philip to go & it seemed you were kinda saying something other than what you intended. I just wanted him to be clear on the converter\dual exhaust thing....

Since I have built a mass air car literally from scratch; I can be quite biased in my opinion when offering advise regarding the early Mustang engine swaps. I cannot fathom attempting to build a serious 300+ horsepower 302 based Windsor, or stroker for that matter, without having issues in California. A 347 stroker would require a bigger carb & possibly a cam that in no way could pass emissions. We won't even go into the choked single exhaust issue! With mass air & a computer; you can tune it to have a "stock' tune for emissions compliance & then a "street\strip" tune to enjoy the performance at the flip of a switch. Larger injectors, throttlebody, meter, intake, etc are all considered "legal" & make passing the visual a breeze. I'm simply trying to put myself in Philip's shoes; but with the knowledge I now have in dealing with this stuff in Cali.....

P.S. I built a carbed roller motor earlier this year for my buddy's '66 Falcon. There still is one pic of the motor in my album.....

It is indeed possible to build a mild 347 stroker in cali... A better carb would need to be used... with the 4180C bowls mod-swapped on. I've research it along with a couple of freinds... There are ways to make an 85 CARB'ed 347 stroker GT look completely stock but still push out 400 hp (or more). The only problem I'm running into is a EGR intake issue. There are no hi-flow EGR intakes available... and therefore one would need to be "worked on" a little. To pass smog an extreem cam cannot be used.... but a slightly hotter than stock cam with a .550 lift can be used and still pass smog. The stock Roller cam on a Mustang is 204*... use a 208* with alot more lift. These are all things freinds and I have been talking about.

Coast High performance has an EFI 347 stroker that is smog legal. But the thing is... it costs $3K or more just for the short block! A smog legal 347 stroker (EFI or carb'ed) short block can be built for less than $2K.

I agree; anyhting can be done... The question is does Philip have the budget for something along the lines of a stealthy 347 carb'd motor or for a simple "freshened up" late model roller motor? On a budget; a wrecked mass air 5.0 swap would be relatively inexpensive & better performing than what he currently has. He could always upgrade the heads & intake to a point like where my car is now; then go even further with a legal supercharger or strok'in the shortblock. He's gotta start somewhere; I just think the mass air conversion would be the easiest method for Philip to "get around' the logistical issues of a bigger intake, more fuel, & a dual exhaust.....

[82mustangGT]

Thats why i thought the Mass air conversion would be better too.I'm only makin $600 a month lol,and I'm still in high-school.So if I could get an EFI engine with all the electronics and the comp,couldnt I basically do the exhaust with aftermarket parts?Or should I stilljust use the stock exhaust off of a wrecked car?
Thanks,
Philip

You should look for deals and take your time looking... look in the salvage yards, the local papers or get to know the local 89+ (for mass air) Mustang guys.

I took my time looking for a core 5L for the 347 I was going to do to my Futura and found a complete 5L (from oilpan to upper intake with injectors) for 100 bux (US). I then found a pair of JBA headers for 80 bux... these headers are normally 400-600+ bux (US) new and are one of the best (if not the best). All I did was do what I sugested in the paragraph above.

[anthonydalrymple]

You'd want to use all the stock parts, in my opinion, at first. Remember; the 88-93 mass air motors are rated at 225hp & will be a performance improvement <even with a 4-cat h-pipe>over your tired carb'd motor.

Like Marz said; try to be patient & let the deals \ junkyard finds come to you. Keep an eye on www.recycler.com; running mass air motors show up all the time in the parts section<use "Mustang" for the keyword search>. PM Jeremy on what he'll give you or sell you cheap<I know he has a complete intake w inj, rails, etc>.

Hmmmm...very interesting.

I need to have my dad check the other YPipe I got in NYS....maybe it doesn't have the cat on it either but I thought it did.

Maybe there was a change during the year?

I remember specifically my dad and I talking about that small cat and how the exhaust guy wouldn't be able to fabricate the Ypipe with it.

Then when I sourced that nearly new Take Off, it was the same thing my dad described. I never got to see the original on my car since I was in NC when that stuff was pulled apart in NYS.
