HELPPPPPpPPP car wont pass 50 MPH!!!

[nibras]

alright so i've been trying to figure this out for a while now .

i bought this ca18det from someone who fried there wireharness and fried the ecu

i bought another ecu and got the harness re wired. i finished setting up the car and have been test driving it.

the car will not exceede 50-55 mph and when i reach those speed the car basically stops and alot of smoke comes out of the exaust for about 5 seconds the smoke is a white to blue color. i see smoke come from the turbo flange too. sometimes the car will stall out aswell when i try to exceede it. the car catches anything under those speed in all gears

possibly bad maf? or ecu?

ANY input will help.

I'll move this to the CA engine forum. Those guys know the CA engine very well and should be able to help diagnose. Good luck!

blue-ish smoke is oil. Have you checked the turbo? If you pull the inlet of the turbo off, and grab the compressor impller with your fingers, you should be able to move it side to side a little, but not so much that it touches the housing. There should be NO in and out play. If this isn't th case, you're probably in for a new turbo. Also, have you done a compression check on this motor yet?

i will test that turbo idea this weekend aswell with a compression test i know for a fact my Fuel pressure regulator is not holding the correct pressure so im waiting on that to come in so i can install it to rule that out of the picture .
