H22 Turbo only boosting part way

The turbo will build up to 14psi normally but for some reason it is only building up to 9psi it tries to go higher but it wont it like fluctuates at 9psi. Could it be the cat being clogged?

Re: H22 Turbo only boosting part way

I don't know much about turbo applications, but my friend had a similar problem and it ended up being a bad spring in the blowoff valve or waste gate - idk which it was. (again I don't know much about turbo things....)

Re: H22 Turbo only boosting part way

Wait, stop, slow down, and gather your thoughts. Now repeat what the problem is.


So your tuned for 14psi, but its only seeing 9psi? Or WTF do you mean the turbo builds to 14 normally??

First and foremost, have you checked for boost leaks?


What vac line is your boost gauge tee'd into?

Internal or external wastegate? If external, what size spring is in there? Are you using a boost controller? If so, what kind?

Need a lil more help to try to diagnose your problem.

You tend to learn a thing or two after building two turbo motors, than moving onto another turbo'd car
