No Full Boost-no Power

[s13onevia]

hi guys having some troubles with my 96 gtst, well symptoms are when i give full pedal turbo spins up to full boost, and it seems like its retarding, full boost and goes nowhere. there is no intercooler pipework leaks, bov leaks so there is nowhere for the air to go, maybe fuel issue??

ideas on what to check for/ anyone experienced similar???

any help apprciated cheers

how much boost are you running?

12psi and above and you hit the factory rich and retard maps to protect the engine.

stock boost

I;d see if you have a bugger fuel pump, or maybe a stuffed turbo.

Take it to a mechanic if you aren't sure about what you're doing.

Sorry not sure exactly what you are trying to say.

So it hits full boost, and the car goes nowhere. When it happens is the boost falling off or it stays on full boost? Also, does it still rev out cleanly but just doesnt feel strong?

Could be simply clutch slip?

Might also be the reason it was fine when your friend looked at, as when clutches first start to show signs it needs a bit of heat to start slipping.

when i accelarate on boost, turbo spools reads 7psi on my gauge but doesnt pull, feels like timing is retard but is not,def not clutch slip i no what that feels like

revs good, idles smooth drives good of boost, only notice it when i sink the boot in

are you reading off the stock r33 gauge ? because its not in psi if you are reading from that one, its in mmhg, +7 is 700mmhg which is 1bar which is too high and the stock ecu is doing its factory protection mode
