Boost max

Izapyou · 11-15-2007, 04:22 AM

I bought a 88 turbo 5spd with custom parts and jdm motor for $800, need info on max boost on stock motor and ecu without reaching serious fuel cut.

Max boost on the stock Turbo is 14psi, im not sure what max boost on the engine is.

And fuel cut is around 11-12psi stock. Fuel Cut is reached at different levels depending on the car.

Ive got a gt26 dual ball bearing turbo, so fuel cut is @ 12 psi. Can you feel fuel cut, and is there a cheap fix to eliminate that problem.

Youll need a Lexus AFM and some 550's injectors, I believe the lexus afm and the 550's will raise you fuel cut to 18psi. Search on Ebay for the Lex afm.

Or you could buy a fuel cut defender VVVVlink

What is the stock turbo number mine says Toyota GT26 turbo is this stock

It may be a different size turbo, the stock turbo on the Supra was the CT-26.

HKS Fuel Cut Defencer

I have a '88 Turbo, upgraded turbo (37 trim) and fuel cut defencer but need 550 injectors. What exactly are these injectors and where can I get them?

550cc bigger injectors, more fuel
an upgrade from the 440cc that comes stock with the motor
RC, Venom, a few companies that make injectors

What about this Lexus AFM thing. I assume it's 'Air Flow Meter' which attaches on the air intake...but do I need it with the 550 cc injectors?
