Need help. Second turbo problems.
Ok ppl, tonight like i was cruising and the car worked fine, i see a stock Supra trying to race me. I step on the petal and the car did not pull hard like the previous times. The supra passed me like i was stopped. Then i realize that the second turbo did not come on. I try it again and the same thing happens. Tomorrow i'll give it a checkout. My thoughts are either the solenoid valve broke and the wastegate stuck open, or a vacum hose came off. Any ideas which vacum hoses could cause that? Or any other places i should check out?
Btw the car has PFC installed. That's why it did not stumble like the stock ecu would do if a solenoid valve is broken. Thanks in advance. Anthony |
What was your RPM right before you "stepped on the pedal" ?
|
It was like 3k but i tried it many times in different rpm's and it will not come on.
|
Did you try doing the "Official Mazda Boost Test" ?

I do have a boost gauge and a boost controller as well....stll the second turbo will not come on. I know what the problem is i just need a little feedback as to what could cause that. And where shall i start looking at.

My fix for that was a popped off line to the check valve that feeds the pressure tank (the black plastic tank behind the alternator). Ultra easy fix so hopefully that's all it is.
|
Trevor thanks for sharing that. I really hope it's just this. It will be the first thing i'll be checking out and will let you know. Thanks again.
|
Yes, check the line Trevor mentioned...this happened to me and it was discovered that the check valve in that line had split in half...
|
Well, thanks for your input guys. You've been really helpfull and saved me lots of time. Indeed that line trevor mentioned came off.
Thanks guys. I really appreciate your help. |
