No boost help!!!
 

my sr20 stop building boost. i dont know what the problem could be. i was hitting about 6psi then i installed a mbc and then nothin. so i took it off and ran a vac line the original way from the waste gate to charging pipe and now theres still no boost. so can anyone can help please

I'm sorry, but my suggestion to you is, you should be much more specific with your issue.

Pictures of how you have it set up would help tremendously.

I take this is a t25 so take the intake off and the outlet pipeand spin the compressor wheel and make sure it spins freely.

Figured it out two bolts some how worked themselves from the turbo tho the manifold and no it's not a t25

Oh well yeah a exhaust leak would definitely cause that no boost issue, try using locking nuts now.but anyways good job

Thanks a lot brother
