So I posted a thread, but i guess i want to change it up a little bit. I have an 08 evo gsr with an aem cai and a gfb bov. this summer i'm getting a buschur bullet cat back exhaust. what are some other mods to get to bump it up to 400 HP? maybe list things that get me to 350, then 400

 

also wanting to stick with 93 octane gas

 

3 port solenoid
dump pipe and test pipe/high flow cat
UICP


I don't work in american horsepower too well but i think for 400whp you will need a Green/EF2/MHI sized turbo, or maybe even the next size up Red/EF3 if you're on 93 fuel.
fairly sure a Green will be just shy of 400whp in dynojet speak? like maybe 380-390?? throw in cams, or go up a size in turbo to be sure

 

I think i read somewhere that if you max out the stock turbo you can make 400... not 100% sure but close.

as far as stuff for the job, fuel system upgrade (injectors, rail, pump) and i'd go with a full IC kit. pretty sure with all that and the stuff you have/are getting plus the 3 port, DP, and hfc with a tune, you'd have 350ish hp

 

Turbo upgrade unless your on a very generous Dyno.

 

Pump gas 400whp is not possible with the stock turbo.

 

I agree, On pump gas on a real dyno, (Mustang dyno usually) u will need IMO IC, all IC piping Full exhaust system, Intake, 1000cc Injectors, up graded CLutch, upgraded fuel pump, might get away with it with stock cams, but most important a upgraded bolt on turbo like the DOM2 which i hit 420 awhp or the EF4 which i hit 480 awhp both on mustang dyno. I wouldnt worry to much about dyno numbers vs actually 1/4 times. Dyno numbers dont mean anthing if you cant prove it. I have beaten cars claming to have 600 hp when i was at 420 awhp lol. They said i wasnt way more the 420, I said your way less them 600 hp hahaha

400 w/ stock turbo and 93 octane. I know numbers are different on different dynos but i'd be satisfied with ANY dyno that said i was making 400 whp with the stock turbo and this powerplant

 

Moore's dyno results... The power levels they claim on the stock fuel system are not possible; I personally do not trust any results they publish. Dynojets read high, but not that high. They are this year's version of TTP.

 

ha!

 

Buy a CBRD BBX (full) Turbo, that's what I did.
