Best way to hit 400whp in evo 8
I want to know what I should do to be able to hit 400whp, i'm looking to use this as my daily and street car. it would be great if i could get a list of previous builds that hit this including internals. not trying to blow it sky high, thank you

I can only speak from my experience but i have reached 400hp on a stock block, BBK lite, RC1200 injectors, AEM 320 fuel pump, GSC s1, mil-spec 100 cell high-flow cat, RRE 3 port boost controller, Turbosmart Evo 9 internal waste-gate, RRE 3" cat-back, random 3" downpipe, and a buscher street FMIC. Granted all these parts combined with a solid tune on e-85 got me to 400. I'm fortunate to have an e-85 station near by allowing me to daily on it. The power levels you seek are attainable with a Evo 9 turbo. What do you have in your Evo? Rather than recommend parts it's best to know what you are working with.

Simple as this:
- Cams (GSC S2s or any 272s and upgraded valve springs if you want 400whp)
- Turbo-Back Exhaust (Downpipe, Testpipe/ HFC, If you have the money ported o2 housing or dump)
- Intake
- 3.0"+ FMIC, LICP
- Fuel Pump (255 walbro or higher)
- 800cc+ injectors
- Evo 9 BOV or something other than the 8 BOV (since they are crap and leak)
- New Tune and E85
- Head Studs
I basically have all of these, but not E85 and I have GS1 cams
Im making 331awhp - With E85 and higher HP rated cams you'll be somewhere around 400whp.. (And depending on your budget, an evo 9 turbo or an HTA71 will boost you HP too
