Thread: Crazy EFI idea?

Dave, I stopped by that shop with a friend when I was still in machinist school. The owner said that when we finished school, we should come back. He might could use us. I've often wished I had. Life took me in another direction.

That was some great times and a real learning experience for me!!!! The Mustang was a one of a kind, built by Bob Riley, engines were done by Gapp & Roush, Doug Nash 5 speeds modded by Joe Liberty----We were terribly underfunded compared to the factory teams, but we did manage to make a good showing for ourselves most of the time. Had a bunch of off time, the IMSA schedule was a short one then, got to do a lot of prep and repair work on different road race cars, some testing time with Charlie for "other brands", and generally a really good time with tons of hours and a really steep learning curve!!!!!

Sounds like just what I was hungry for at that time in my life. If the planets had aligned a little differently, you and I may have worked together.

I like the way you think Mike. building this yourself is the truest form of hotrodding. so many people listen to the voices saying "you can't" and they never get the pleasure of doing something out of the box.
I guess I never looked at a TPI egr port close enough to know how it's routed in the lower manifold. does it connect with each individual runner? if it does, then I can't think of any reason you couldn't use it to feed air for the iac. you still need a way for the ecm to control that air however. I don't know if you could machine right into the manifold to fit an iac valve directly, but you could thread the opening and plumb it to a block like the one I machined for my Northstar itb system.



The dual TBs seems like an easier way to handle the iac at first blush, but I'm not sure you could use it as-is anyway. trying to control two could be an issue in keeping them in sinc, and you can't just use one side because they are isolated to each bank of the engine.
the dual TBs does make it easy to hook up the TPS control, but that would work the same with any number of TBs. on my Northstar system I used TBs from (2) GSXR600 Suzuki bikes and was able to keep the Suzuki TPS sensor. I think most brands of TPS work in the same ohm range, and any ecm I've used was able to recognize it's parameters without any problems.

regardless of which way you go, have fun with it, and I look forward to watching.
