well have a 81 rx7 with a s5 13b turbo but in.
driving her hard on the weekend. i hit 3 gear hard and then lost all boost
it;s like driving a car that has droped a plug. all of my oil. cooling all fine. had a bit of smoke when driving her home i was running 10psi at the time.

 

well for 1 the car is only suppose to run 5psi(roughly) stock. is ur car stock? Second if ur turbo blew ud see smoke plume like crazy(blue or white) depending on the turbo seal u blew up. Check for a massive boost leak like the intercooler pipe blowing off or something and if not disconnect the intake pipe to the turbo and check for shaft play and oil....

 

cheer,s mate ill get back to you asap

 

it has a MT-4 microtech automotive system
rev's pro shop here in adelaide set the engine to run 10 psi
I had a look in the shaft there is no oil.
it just will not spool up me boost is saying it's running 5psi but i dont think so.and stell get blow off when gear up but car go,s has no power at all.
its a dog to start. there is next to no smoke from the back.
next ill look at the intercooler i dont see a leak but look at it better tonight.
