if i have basically a stock evo 8, whats the cheapest and quickest way to get to around 400whp? with good quality parts that will last.

 

AEM intake, 3" turbo-back exhaust, GM boost control solenoid, FP Red, E85, Walbro fuel pump, injectors, ECU tune. About $4 - 4.5k for parts and installation.

 

a 150 wet shot of n2o hahaha

 

all Bolt on plus e-85 should be close.. i made 394 (evo ix tho) with the mods in my sig minus the cams

 

And with those cams you will do WAY well 400WHP. WEEEHE!!!!

 

so its gonna cost 4 grand to get to 400 whp? i was hopin to do like 1 or 2 things, plus a tune, and be pushing like 380whp

 

^ Well, this is real life, not fast and the furious... Your best bet is to follow a similar setup like drinky84.

 

if i didnt mod anything and i just got a tune i heard i could get 30-70 whp is that true?

 

no, full boltons + RED u'll be a lil over 400whp

 

Like everyone has said all bolt ons plus e-85 or meth. i have ix with TBE, manual boost controller, 02 dump, intake ,UPIC, LICP, ets 3.5 ic, walbaro 255, 50/water 50/ meth injection tune, shep trans/ Fidanza 4.3 clutch and made 349 on cbrd mustang dyno if i woulda been on a dyno jet i woulda made a lil over 400 Thats an ix with stock turbo stock cams, stock head and stock block. But e-85 is suppose to make more power than meth so if u wanna be closer since u have the iiv go with e-85 instead of meth.

 

Yes, that is true when compared to the stock factory tune ... you need to do some more research, but to get you started: from the factory the Evo has 286 bhp at the crank, so approx 230 whp stock (i.e. bhp at the wheels) once you account for drivetrain loss. Since the factory tune is somewhat rich, yes it is fairly easy to get to around 300 whp i.e. 70 whp increase, depending on supporting mods.

Stuff for the Evo can be expensive. Here is a rough list of parts costs (parts cost only, installation NOT included) that will be needed to even hope to get anywhere near 400 whp:

Drop-in filter: $75
Walbro fuel pump: $110
Injectors: $360
Turbo-back 3" exhaust: $800
Tune: $450

That will probably net you somewhere around a little over 300 whp for an Evo VIII on a Dynojet on 91 pump gas. Maybe somewhere around 350 whp (?) on a Dynojet on E85 (though once you start upping the boost you probably want to upgrade your head studs as well). And remember, if you want to get tuned for both 91 and E85 because you don't want to run E85 all the time, or don't have access to E85 all the time, your tune will likely cost more than $450.

From there, things start to get more expensive e.g.
- $900 for cams, springs and retainers
- $800 for FMIC and lower intercooler piping
- $1800 for FP Red turbo upgrade
- $500 for clutch
- etc.

And remember, all of these are parts prices only, and do not include installation. If you want to make power, costs start to add up quickly!!

 

Every heard the term, "you gotta pay to play" well this is were it apply's

 

I think you are mistaking whp for bhp. A stock Evo make about 300 bhp which is about 225-250 whp. Its a long ways to 400 whp from that starting point.

 

whats the diff between bhp and whp? thanks for all the help guys
