    There was another power-train engineer who discussed the turbo 2.3 gearbox development and vibration and noise updates last year. Those guys normally hang out with certifications, so they have access to development info.

    An earlier non EFi fuel engineer will help you out.

    Ok so a few more hours in and we are 90% through the vacuum line tracing/fixing. I've added the two lines for the A/C side (right) SOLV and part of the anti-backfire device as well as completed the A/CL BI MET lines. She is idling and running very well and spools great except for now after the other vacuum fixes I have a concerning carb backfire/poof with a cloud of black smoke when on full throttle and I put the clutch in to shift gears (so much for adding in the anti-backfire device!). If I make very slow shifts it's no problem. This is no buenos and must be fixed so I won't do any further full pulls. I'm sourcing the missing A/CL TVS from National Parts Depot so I can fully connect the AIR BPV/ANTI BF system which I hope will solve this issue as I don't want to blow up the turbo carbon seal. I am doubtful but may play with the timing again in the meantime.

    My AFR gauge still does not read at idle by wiring directly to battery so I think it needs to be replaced in order to trust the readings for fine tuning.

    I do not see the FLTR that connects to the AIR BPV in my engine compartment as that upper port is closed. Does anyone know what it's function is and have a picture of said FLTR?

    Finally this is the Vacuum Control Valve right?

    This pic is my old setup with lower VCV port going to the IVV and the other to the air port next to the primary carb mixture screw. The IVV lines are now fixed per the VECI diagram (to small A/CL CWM port and to the formerly open EGR port) but the VCV lower port is now open which is supposed to go to the E port on the carb with a SA FV which I also don't have). It is supposed to go to a tee then to the VDV then to the purge canister center line which is also open at the moment. Looks like I need to source a VDV and SA-FV in order to finalize all of this.

    Lastly I have a large vacuum line (turquoise stripe) running from the firewall RT corner area to the large A/CL CWM port but I can't ID this Line on the VECI. Anyone know what this does? Does the stripe designate something specific? At the split valve one goes in the firewall behind the glove box somewhere while the other one disappears behind the fender.


    Here's my Purge CV with middle orange?/pink? (it splits into two lines not sure why as the VECI only shows as single line; same thing on the Left SOLV lines where both split into two then back to one...strange) that needs to route to VCV.

    Well I have my new red NOS TVS and retaining clip from NPD as well as the replacement AFR gauge from AEM. My gauge was deemed bad after the brake clean rag test confirmed the gauge was not reading accurately. Will install and test this weekend and if all goes well take a trip to the smog man for a test. Already purchased my ticket for Goodguys show end of the month so going to make this happen!

    The line running to the passenger side fender and through the firewall to the HVAC is from manifold vacuum to the HVAC controls. The line teed to go under the fender as there is normally a vacuum reservoir there to provide a constant source for the HVAC controls. The Tee fitting probably has a check valve in it so that nothing else can pull vacuum from this reservoir except HVAC valves from under the dash.

    It was a stunning, sunny day so we got the TVS and all the vacuum lines hooked up and triple checked. We are currently running without the VDV and SA FV that route in the lines from the VCV to the CARB and Purge CV on the right side of the diagram. We checked the parts store and they could not find a cross reference for either Ford part# nor do I have any specs on them so I still have a little hunting for those two last items. There are a couple carb vacuum lines that I can't decode (neither could my carb guy) but think we have it right and they all have a home.

    The BAR referee shop said I don't have to see them for the smog test and I can go to any smog station so I may run it as is without the VDV and SA FV and see what happens.

    Otherwise it's running well and we hard wired the replacement AEM brand AFR wideband gauge but unfortunately it too is not reading right so need to still figure out what's going on with this before I get on it for fear of going lean. Time for some cleaning, detailing, install the NOS BBS caps, address the brakes and cracked steering rack bellows. The list is getting short in time for Goodguys! Hope you all are having a great weekend.

    I'm killing you all with this I know but I'm down to sourcing literally the last two parts to make this 100% right and could use any helpful eyes/tips on ID'ing these correctly.

    SA-FV-
    I think I need SA-FV part # 9C369 however the only thing I am finding is stuff from presumably 1974 D4FZ-9C369-A which may or may not be the right one for my application. Does anyone have have a clue if there is current or changed part# for this or can I pick this up with confidence? Looks like this:


    VDV- Vacuum Delay Valve sits between Purge CV and tee that goes to the upper port of the VCV. It is not tied into the SPK RET system or distributor and I don't have any kind of spec on it or know which color I should buy. Parts store had 5 different ones with different colors including black/opaque and none cross referenced to part# 12A189 listed in my VECI book parts ID section and there is no specification. FleaBay has exactly four listed all with different colors as well with Black/Yellow, Blue, Brown, and Red and indicate "Spark Vacuum Delay" and list DIST and CARB on each side rather than just Vacuum delay so not sure this is the right type of delay valve. How the heck do I choose or ID the right one without finding a 1979/80 in a junkyard that happens to have one?!

    I don't know if this will be of any help at all, but I'll post it just in case. They are Ford photos of a 1979 Mustang 2.3l engine compartment. I do not remember where I got them. You might be able to zoom into the photos and look at the colors of the parts or vacuum hoses and learn something.

    Nice. Jacks two photos are shown as itemized and labelled in the same landscape and portrait pictures.(See bellow references so as not to post hog).

    Ford used 9 element code breakout coloring for VECI's as of 1982.

    Stormin'Norman's source of color identification

    Red = Main vacuum
    Green = EGR function
    Orange = Heat control Valve (exhaust & intake) (AKA heat riser but more complex)
    YellowYellow = Distributor advance
    White = EGR vacuum (source)
    Black = Mainly used for the Evaporative emissions control
    Brown = Thermactor ACV or Diverter valve
    Blue = Throttle Kicker control
    Pink = Thermactor Air Bypass Valve (BPV)




    The photo below and above use a different 10 element Air Conditioning, power steering and Body Vac catagory. Internally, Ford had it all mapped out, the call names are the same basically.

    Gregpro in post # 10
    Georgez in post #17
    and myself in post #11 itemised the exact location of the VDV, which is in the 2.3 Turbo Carb, white and black VDV.

    Go to Gregpro's post on page 1 of 3

    The VDV has been shifted closer to the carb on the Turbo 2.3

    Wow thank you Jack and X! Jack do you happen to own an early carb 2.3T? Those factory pics are amazing!

    X, thanks again for the references on the VDV. I can see in those posts the black/white VDV so that's what I believe I need. I'd love to see if anyone can confirm the if their VDV in between the Purge CV and VCV has part# 12A189 and if it says CARB on one side and DIST on the other. All three cars have a slightly diff setups which is expected. The pics also confirm the SA-FV which I now find on NPD's website (edit- actually now they say it is NLA) so it's down to getting the correct VDV as far as the 49 state VECI diagram I'm following goes.

    No I don't. But I do have a 2.3l Turbo in a MazdaSpeed6, a 2.0l Turbo in a WRX and a 2.3l Turbo EcoBoost engine in my 1987 Mustang. No carbs anywhere

    I don't remember where I found those Ford photos, but I definitely made sure to save them.

    I have 2 factory 2.3 turbo cars that are all stock and have all the vac lines and turbo and housing from a car I parted out years ago . I have a lot of the little round plastic vacuum pieces also. What one's are you needed ? I probably have one stashed away. Let me know if I can help . 515-249-5253

    Thanks Jack. Holy crap I'd love to see that Ecoboost fox sometime. I'm very nearby if you ever get out and about!

    Hi Indypacecar, I am looking for the part number for the small black and white Vacuum Delay Valve as shown in this picture. It connects near the Carb and the Vacuum Control Valve (which is on the top of the manifold next to the turbo).


    I think it's now likely 12A245 or 9E897. I am not smart enough to understand how the system flows (bi-direction or only one way) or I could narrow down which one I need. I cannot find a 12A245 in any of my parts searches so I may be out of luck. Also in looking at GeorgeZ's pictures he appears to have two VCV's whereas mine only has the one but at least if I could find out which part number is on his VDV I could feel good that it's the right one.











    I am also looking for the other device the SA-FV in the picture but that is still available new on EBay. Thx!!!

    Awesome! Does that line from D32E-AA (aka 12A091) white side route to your distributor or does go across the engine bay to the Purge CV (the green thingamabob with 3 ports on it)?
    This one


    Thank you!

    Perfect! I'm betting it's the right one because it goes to fuel related and not to the distributor to perform a different delay function. Thank you so much for the help and picture upload. Now browsing EBay as all 4 of my local shops are a no/go on this one and the SA-FV.
