turbo psi
just a quick question on a '94 MR2 turbo with stock internals, what's the highest psi you can somewhat safely run? and how high can you go with upgraded internals?

Re: turbo psi
If you are using the OEM turbo (CT26) do not exceed 15 psi.
However, with proper enginemanagement, proper intercooling, proper fuel and an upgraded turbo .... .the sky is the limit. I am running 23 psi on a 197,800 mile 91T engine with a T3T4 turbo.

Re: Re: turbo psi
My engine is 100% original.
Toyota assembled it 14 years ago and the closest anyone has come to touching it is me installing a powder coated valve cover.  ... head, block, head gasket, pistons, crank, rods, valves, springs, etc .... all original, untouched.

Re: turbo psi
91 octane? ... seeing as the engine the engine requirements are for 93, I would not go over stock boost.
Personally, I wouldn't even run that hard unless I had water injection.

Re: turbo psi
what EMS are you running ..and what sort of A/F ratio do you tune for?
thats an acomplishment for no internal work with that many miles. does is smoke ...even a little? the cylinder walls and or piston rings gotta start wearing if not yet ...sooon. its inevitable. and if so what will be your replacement?

Re: turbo psi
1. Right now I am on the factory ECU tuned with SAFC, VPC and AFPR. A/F was kept under 12:1
2. It does not smoke at all. 3. 15,000 miles of using water injection and I have perfect compression - 176 across the board. 4. 90+ 1/4 mile passes, 20+ dynos pulls, lots of hard street driving and one serious weekend of Hill Climb racing
