Maximum boost?

[ToyMr2GT]

Hey guys,
i just bought a 1992 MR2 GT, i was just wondering what u guy think would be the safest maximum i could boost the turbo upto with stock internals?
it has:
a Blitz ecu,
Blitz exhuast,
upgraded turbo (not sure, but is larger then stock),
side-mount intercooler,
cold air-intake, &
upgraded Apexi fuel injectors.

Thanks in advance

It's all in the tuning.. Plenty of fuel and cooling. Keeping whatever turbo you have within it's effiency island.
You do need to know what turbo you are using. What intercooler you have and injector capacity/flow. What about your fuel pump and FPR? Are they upgraded too ?
Is your 2 JDM ? I don't think the USDM's were badged GT.

umm nahh it doesnt have a gt badge, just assumes cos i thought all mr2 turbos iv seen have been gts.
do you know wot the stock boost shuld be?

Nobody can help you unless you know what your car has. Either way.... safest bet is to take it to a competent tuner with a dyno.

Stock fuel cut off for overboosting is 12 psi. But since you don't have the stock turbo and ECU, thats irrelevent. Take ishcoleobo's advice....
