Gtst No Boost

[tstg23r]

Hey everyone. My r32 gtst 4dr the other day started momentarily struggling on boosting, it would hesitate and make a deep whoofh air sounding noise or something for a second, then a day later it stopped creating boost all together(creates maybe 1psi instead of 10). There were no exhaust leaks arround the turbo from what i could tell and all the intercooler piping was tight. When i took the cross over pipe out though there was a bit of oil in the bottom, someone told me that was normal?. I took the turbo to a turbo shop and they said it looked fine. Any suggestions would be appreciated.

cheers

does your car blow smoke?

Check the BOV hasn't seized open.

PlasticStan, thats a good idea.. could be fully opened... block off the plump back

Good idea bout the BOV.

A friend of mine had an RB20DET which stopped producing full boost and it ended up being a partly blocked CAT. The insides had melted/ broken apart and formed a fairly solid blockage. Replaced it and all was fine, could also gut it but not as legal. Could be worth pulling it off for a quick check if nothing else seems to work.

If the turbo was standard then I would say it could be a bent turbo shaft. Have seen that also and the series one turbo has a black plastic compressor wheel which made a weird siren like noise as it span up and hit the compressor housing.

Anyway, Good luck with your problem

Hey Guys, ProblemS solved, It needed new exhaust manifold studs and a new turbo. G&A motors in brisbane fitted a new chinease hks copy turbo and it rips at 13psi. Cheers
