Plan is to get an ST205 specific Apexi programmable ECU and then wind the boost up to around 23psi. Should see around 400bhp then. Muhahahahahaha tongue.gif

those are nice... but why are you doing pistons? the stock 3s block can hold a lot of power before you have to crack into it

Pistons will fail at 23psi. They're only good for a max of 20psi apparently. Rods are good for a lot more though.

that really depends on what turbo you run. ... dont get me wrong, those pistons are hot, but i would think of a HP goal instead of a psi goal, because not every turbo makes the same amount of power per 1 psi.

so, what type of power do you want to make.. 400hp ?


Hanyo, ive had mine up to 15psi. thats basically the limit for the stock ct26. if i upgrade the turbo, then i can lay down 260 ish hp with the stock fuel system. if i upgrade the injectors and get a piggy back, then i can go even higher
