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???

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.

yeah my mates a mech, and he is going to be piised off because driving it around to his place just then and its driving fine hehe and i know how mechs like the eratic probs.. cheers

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

stock boost 7psi/ .5bar if you like

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
