Thread: Turbo Problems Please Help!

okay everybody, got my ecu back from jwt. changed a couple things. got it actually tuned for the Z32 maf and went 4 bar.

car would not start so after hooking up a fuel pressure gauge I saw that I was only getting about 18psi of fuel and then it was dropping back down to 0. I dont know why but my walbro 255 seemed to just be worn out.

so... me and Dracer stole the 255 out of the DVLD EGG and and also put on nismo fpr and set to 58psi. fired right up but I am still having idle problems.

It keeps dying but if you keep it running with the pedal you can drive it around and it runs great! We have went through all vaccum lines and couplers replacing every little thing that may be old or leaky. Im not sure what to be looking for next. I can possibly make a video of whats going on to give everyone a better picture. I appreciate all advice!

could be a iacv issue have you tried cleaning that or the acc valve

i did this and all of my idle and stalling issues stopped.

the iacv seemed like it was the idle problem but I have bigger problems now.

I was test driving the car and ended up making more than double the boost I was planning on. so #3 spark plug came out and ruined the threads in the head.

Bought a helicoil kit but havent ever done one before...

Car wont start of course but cranks fine I dont hear any bad noises so I dont know if I could have broken something else?

Do you have a boost guage? not good to just go full boosting on a test drive trust me I've blown a turbo doing that. The helicoil kit is pretty straight forward I helped a friend do it on a Subie spark plug 2 years ago and it still hasn't come out. Clean out your IACV and re-check your vacuum lines. Hopefully you didn't blow that ebay turbo cause they blow quick. Good luck...

Yea I have a boost gauge. I will probaby use the helicoil tonight. Also I will take off the filter and check the turbo. Thanks for the info

Have you pressure tested the system yet? It's possible the wastegate actuator is toast and that's why you overboosted. This would have been found during the pressure test.

Well no I never did the pressure test. guess I will learn from my mistakes right? Im still a noob at everything. Im not sure what the deal is now. Makes me wanna give up sometimes but I know its not easy if I wanna go fast...

Put the helcoil in and it held good just still no start. was cranking and then finally quit. the starter was just clicking. had it hooked up to jumper cables just to make sure it had enough power and the starter I just put in a few weeks ago so now I am thinking it may be locked up..
