Ok so I rebuilt my turbo and re ran the oil feed today, after I plug in the new FMU and get it running tomorrow I'll take pictures.

Where did you get the charge pipes from?

Interesting build, very cool that you are using the stock ECU for it all. I wonder how a chip would affect the performance.

Ebay. Lol. Some hundred dollars universal kit.

I'm gonna get my hands on some 30lb volvo turbo injectors so that I have more room to play with my fuel.

If I were you I would be thinking about 42# so you can run 12psi and a tune down the road and just use a lower fuel base presure untill then with your 7psi

Well 30lbs are cheap and easily accessible till I get some much needed cash

I have a question. I'm looking at doing the same on my M42.
I haev found some 30lbs injectors that I plan on using, I have a Garrett td04-11B from a 524td and I'm gonna use a manifold from an M50 that I'll modify.
For the fuel pressure, do I only need an FMU or do I need a fuel pressure regulator on the side as well, I seem to see both solutions, what is the best to be able to tune it a minimum.
I'll be running a stock ECu btw.

Thanks a bunch

You need an FMU because your normal fuel pressure regulator is rising rate as well.

Get 30lbs for sure, I'm still running lean with my stock 19lbs. Make sure you have a GOOD A/F ratio gauge/

Hey danny let me know how your car run's with the 30lb injectors on the stock ecu .. thanks!

For sure, they should be in sunday.

excited to see how your car run's on the 30lbs ... can you take note of the narrow band reading's untill the computer adapt's and how the car starts when cold ... thanks

Danny707 · « **Reply #130 on:** January 18, 2009, 03:24:21 AM »

For sure.

The anticipation is growing!

Well 30lbs is definitely overkill lol.

Runs so rich at idle that its loppy.

But meh, pulls way harder and stays rich through boost, we'll see if the computer learns in 30lbs over a few days.

So I'm trying to follow all this and a lot of it is new to me. I'm interested in budget building as well and am willing to take some time and collect the parts I'll need.

Any way of putting together a "shopping list" of essential parts and the cars they come from etc? Mitsu or Volvo turbo or Isuzu intercooler etc.

I see you are testing various parts so I assume things can always be improved down the line. Great info so far, I'm also looking at the thread on the bottom mount turbo option.

And I can't tell how close or far you are from your goals:
"7 psi under a grand.
~175whp without pulling the motor.
Done in a weekend."

you need to get inside the afm and tighten the spring it will realy help you for idle and cruise and thanks for the info
