Jaws Yeah, it pulls like a freaking train. I haven't hit it that hard yet but I did give it the full goose once and the tires were screaming in second

Saabeh Damn! Thats a quick turnaround to a stage 5 car haha! Must go like stink!

Jaws I finally got a JZW Stage 5 ECU, Green Giant injectors and the 3 bar map sensor installed. I pulled a real amateur hour and wired the IAC to injector #1 and vise versa. This cost me a trip to the shop but it's back and running strong! Only got a few miles now but it really runs nice!

NeedForSwede I'll be doing the same thing this weekend when it's time for an oil change.

justineffingp having the exact same issue with my car, havent compression tested it yet, but hoping its the same thing. Whatd the gpopshop rebuild cost if you dont mind me asking?

I have a tdo4 at home that needs a rebuild as well, so i'm up in the air about what to do lol.

Jaws So my T25 is at the GPOP Shop getting rebuilt into a Big T28!

I'll be running this on lower boost (19-21 psi) until I get injectors, 3 bar map sensor and a fuel pump.

Jaws The compression numbers are in. Done hot w/ fuse 32 removed. 110k miles on motor. Numbers look real good so maybe time for the Big T28. I’m a little undecided since the car’s a little long in the tooth but I know I won’t be happy with another car short of a CTS-V, 335, STI or M5. Need 4 doors.

1 = 205 psi
2 = 205 psi
3 = 205 psi
4 = 200 psi

NeedForSwede I have a feeling it's your turbo. I bet it burns right in the beginning of going WOT and then returns to normal through the rest of the RPMs.
08-14-2012 07:54 AM
Jaws Thanks - I agree, probably the turbo seals. I'm going to pull the plugs later this week, look for signs of coolant and check compression while there.
08-14-2012 06:34 AM
win_k First guess is the you're losing the seals in the turbo.

A cheap rebuild kit for the turbo is about $60, a better solution would be a rebuilt center section.

Probably the best low cost option would be a used turbo (if it's got a warranty)

Exhaust Smoke - My 99 9-3

So my car started smoking a few days ago. It is releasing a blue and white smoke when hot. There is a nasty burning smell sometimes. It does not smoke at startup that I can tell. It appears that I am losing some oil and coolant via burn. No leakage to the ground. It still runs normal but maybe had some loss of boost before the smoke started. I am running on base boost now.

It smokes between shifts and when decelerating but not at idle and not when cruising. It does not smoke at WOT. It smokes when I rev it sometimes.

What say you? Iím thinking head gasket or my stock T25 turbo has failed. The head gasket was replaced 7 years ago before tuning. I have been running stage 3 at 19.5 psi for the last 2.5 years. Iíve been running it hard in the heat lately (never overheated and low speed fan works OK).

If I do a compression test and if the numbers are 180-190 psi, can I conclude that the head gasket and motor internals (pistons/rings/valves/valve seals) are good? Any other thoughts as to the cause?
