how to get 3sgte past 320 hp? Options

[coustoe]

okay, im getting a st205 clip soon, I know it comes 255hp but 255hp seems so common these days in stock cars, what are the mods starting from greatest hp gains to least that I can do to increase the engine to 320hp?

Therefore, you would be looking at a high flow filter like th HKS MegaFlow Filter

No - not the dirt shroom!! Stay far away from that filter, every test its been in showed that it allows the most dirt through. Go Apexi or K&N.

The ct20b that comes on the ST205 has put down over 300HP to the wheels on a couple of MR2's. It's a good little turbo, but if something happens to it your screwed. Try to find a place to rebuild a ct20b in the states. I sold mine on day 1 and bought a Greddy 20G kit.

The ST205 has 540 cc injectors that are better then the Supra's 550's. 4 jets versus 2 for better atomization. While your doing the swap, ditch all the banjo bolts on the fuel line an replace them with AN fittings. That will greatly increase the fuel flow in the system and it'll only cost around $50.

The ECU can handle a 350 HP engine without problems. Add a S-AFC for better control, but its really not needed.
