I love the spool of my set up with my S15 turbo/ GT28r! Starts boosting @ 1300 RPM Full boost @ 2800 RPM It can make 330whp with supporting mods.

You don't need forged pistons or rods unless you plan to make more then 400-450+whp! You don't really need cams to hit 350whp but they would help.

The most common turbo used for that hp range is the GT2871R .64 like mentioned above. Aftermarket headstuds and head gasket isn't really needed, but it adds further insurance. I'm still using the oem headgasket and headstuds.

Do you know what rpm boost starts and then reaches full boost on the 2871r 64/ar? Do you have bigger cams or aftermarket exhaust manifold? I really wanted that turbo but the extra $500 went toward a nismo 2way lsd at the time.

it hits full boost around 3500 with 264 cams and MR manifold.

Look on Phase2motortrend.com under the GT2871R turbo. They should have the size you need.

I've got the fmic and fuel pump. That's my goal is ~350whp for daily. And good thing the stock internals can do 350whp cause I dont' want to do a massive overhaul unless needed. At least, not yet

*edit* nevermind, made my choice.
