I am here reading these post about high boost and high horse power. what about a balance street car with good throttle response like the MR2 Beast, usuable reliable horsepower. I seen car with less horspower and less boost potential smack up high horsepower cars many times. A good street car is a terrible track car and visa versa. Know what you want and build it and understand what you are building and how it best performs.

Presure2 car is a perfect example of useable , reliable responsive horsepower. This is my 10 cents.

We all agree that 3SGTE is the ideal motor and has more horsepower potential but as we are seeing 5S is cable of matching the 3S with mild mods with out the swaps.

Trust me I have noting but love for the 3sgte...it is a remarkable engine but is not the only fun engine to drive i have a blast driving my boosted 5S and will sooner or later build a mean 3SGTE project, but all of us dont have swap shops and tools, some of us want to tinker with out rides and learn about boost before investing 2500 for a nose clip 3sgte and non smog legal motors before we take the 3SGTE.

some of us need to drive low boost and so on before building road wrinkling monsters.

I readign in a 96 turbo mag they tested a 2.2N/A with a turbo in a MR2 and it blew up at 327 bhp on stock internals on 14 psi and 111K on the motor. Back then no one new about DSM injectors on a 5S.
