Hello,

I've been collecting parts over the past year or so and ready to start my e32 project. I plan to start at low boost, possibly increase in the future if everything runs smoothly. The e32 will not be a track car, but I would like a few extra hps for the highway cruiser. Here's my plan so far, hope to hear your comments/advice.

745i parts I plan to use:
- exhaust manifold
- turbo
- waste gate
- air to air heat exchanger
- down pipe
- most plumbing

Parts I still need:
- chip - TCD
- FMU - TCD
- Injectors (24 or 30lb) - TCD or might get the 745i injectors cleaned/tested?
- O2 clamp - TCD
- Oil lines for turbo drain/pickup - ???
- 8mm studs with sleeves to fit 10mm manifold openings
- misc couplings, etc...


Still need to sort out:
- Best way to tap oil line in and out
- Vacuum lines (I think I just need to get educated)
- Any custom mounting work needed?

Just for fun... No comments on the stand please :)

Seems I'm missing the pipe existing the heat exchanger leading to the intake. Anyone have one lying around? I assume I'll have to fabricate.

I'll also have to figure out how to mount the AFM.

Looks like a cool project!

Factory oil supply is from the oil filter housing.

If you're going to remap for more injector, why would you utilize an FMU too?

This is my sig...

Four 745i! One '83 and three '85...I am a glutton for punishment.

I think TCD's chip (programmed by Russ C on this board, I think) is designed for use with the cartech "UFO" style RRFPR.

Thanks for the input, Scottie.

I've ordered a Begi 2025 RRFPR from TCD.

I'm looking for a couple more 745i parts and I figure the members of this board may have something lying around. Is there a better place to post this request? I'm looking for:
1) Oil filter housing # 10 (I have the head)
2) Pipe from heat exchanger to intake



Thanks!

Yeah, BEGI is Corky Bell's new company if I am not mistaken.

You may want to post a separate post in the wanted section.

I have officially past the point of no return. This weekend I removed the stock manifold and replaced it with the turbo mani. I was really worried about breaking an stud, but they all came out without too much fuss.

I'm searching for some plumbing ideas. I have all the 745i pipes, but I don't think it's possible to mount both the intercooler and the intake on the passenger's side like it's done on the 745i. Just not enough room in the e32.

I might be able to use the 745i intercooler mounted sideways but the vertical "stock" position is too high because the a/c lines get in the way. Here are a few picture. I'm guessing I'll have to run the intake from the driver's side.

What other options do I have? What should I avoid?












Thanks for the help!

You'll probably have to abandon the idea of using the stock 745i intercooler and go with another unit, perhaps a custom one. A long thin one will fit behind the front air dam.

That's what I'm leaning towards right now. I need to pull the bumper cover off to see how much room I have.
