2.3 Pace Car Re-Power to SEFI 2.3 anyone done this?

[rnjstel]

Long Story Short, after getting the Carb set the Vac sphagetti straightened out and the Turbo to work a "spirited" run of the Pace made the motor start the journey go to meet Jesus.

Now its making boost, it has massive blow by (not just the Turbo but a leak down test shows it from the valves and rings).

Bottom line its getting a re-power and the Carb'd set up is going. Its my car and that is the way it is.

I will find a T/C or Xr7 to donate its T-45 and 2.3 SEFI set up. Has anyone upgraded an older Carb'd 2.3 to a SEFI set up?

I can figure I will need a later Fox Mustang SEFI Tank and Lines. The Turbo-Coupe or XR7 should be able to donate everything else.

Any thoughts or problems that someone may have ran across would be helpful as I begin to aquire the parts.

Thanks

I thought that motor was supposed to be rebuilt in that thing??

Definitely an SEFI turbo swap would be cool. I havent done the wiring aspect of it but I can help you out with getting a turbo coupe motor in it since I am doing it with my SVO.

Well not to be "picky", but a 2.3T would have a T-5, not a T-45 trans and the 2.3Ts were not SEFI, but "merely" EFI (batch-fired, not sequential).

Using a harness from an SVO, GT Turbo or an 83-86TC/XR-7 will be the best (easiest) route wiring-wise as they are the more simple harnesses.

on my capri i bought the nylon fuel line from napa and the connectors to make custom lines

Also, it may be possible to just use an inline pump instead of swapping in a later tank. Some of the Bosch units are pretty stout and do pretty well as a "gravity" fed high-pressure pump.

Bosch pumps apparently are a bit more stout than their Walbro counterparts (at least from what I gather from a discussion on TF). Here's a Bosch application chart with flow numbers

http://apps.bosch.com.au/motorsport/downloads/fuelpumps.pdf

most of the Bosch pumps for the mechanical injection will bury a Walbro. I have found lots of info to back that up. The F150 pump is just a little better than a 190 ltr/hr walbro. If you want a killer junk yard pump look at the mid 80's VW,Audi,Porche. Some came with a 1/2 inlet. The Bosch 044 pump is bad ass. The 044 flows ~240 L/hr @ 60 psi and stalls @ over 150 psi.

Yup an inline would be simple and not have to worry about searching for a tank with the correct sensor :(

It was "rebuilt", but as far as what the previous rebuild was who knows. Its all pretty and blue though.

It ran fine until the Boost fairy came to visit!

(and plus be careful with the 4-speed. They are sloppy its easy to bang into 2nd when you mean 4th..oops) 8O

It still runs just, blows oil like a pig and taps and knocks.

thanks I was thinking T-45 as an XR4Ti would be just as good of a donor for the powertrain.

I know the SVO or Turbo GT would be the easiest conversion platform. I just could not bring myself to strip one of those.

Thanks for the fuel pump ideas!

The inline would be way simpler but, would the Processor still drive the Fuel Pump Relay or, would it just be wired to have a 100% duty cycle Key On?

Or, do the injected Turbo 2.3's have the pumps on all the time?

For instance some 4.6's are returnless and control the Fuel pump via a duty cycle depending on fuel need.

Thanks

The "T9" in the Merkur isn't much of a good choice for donor transmission. If its all you can get your hands on it'll work though. Not sure how it'd fit, hopefully it'll fit like its older 4 speed brother(which I put in my car when I swapped till I got a T5).

You'd wire the inline pump same as Ford wired the factory EFI pumps, relay to switch it on, and run a return line. And the pump always is on...can hear when i'm standing behind it :)

I thought the Merkur harness was the easiest to use? I thought it was the most "stand alone" for swaps into carbd vehicles.

[Mustang Marty]

The XR4Ti (Merkur) harness is the best one to get for a conversion since they are separate from the main harness. Basically the XR was a convertion from the factory since the only the US XR got the 2.3t. The US bound cars were modified on a separate line.

you can use a later efi tank, but you need an 86 GT sending unit for your gas guage to work.

GT, CFI V6, and Turbo 4 EFI(I think). All will work.

Also CJ Pony parts sells them for $100

Otherwise your guage will read incorrectly.

cj said they didnt have the sending unit anymore when i was looking but 50 resto has them (latemodel restoration supply)it was around 100 bucks to

[rnjstel]

You guys rule!

Thanks I never thought of the XR4 being a better donor but, it make sense since the 2.3 was swapped in by Ford.

So, I could find a XR4 instead and get a T-5 later. The Intercooler (or lcak of) is no big deal as I am going to plumb a Volvo style one in front of the radiator.

Thanks

you animal...

[Travis T]

You'll have to cobble up something to get the XR4Ti T9 transmission to fit. The rear mount is going to be a PITA.

[Schlodes]

Also, you could use the 87/88 TC fuel lines too as they are the plastic ones. Thats what I am gonna do when I start on my 80 Capri Turbo here soon... I have a complete 87 TC outside and im gonna use the lines and fuel rail from it in the Crapi.. I also have a tank and pump braket out of an 88 2.3 EFI stang. I have the hard style fuel lines too for the efi 88 4 cyl car but i'd rather use the plastic lines.

find a SVO mustang and gutt it completely.Take everything with the wiring and fuel system and transfer it over. The other thing is the Turbo Coupe swap and harness, then use the www.fordfuelinjection.com or www.windsorfox.com to redo your harness.It will be a good swap to do,but it will take time.
