I have a 2006 evo mr 100% stock and I'm looking for a somewhat budget way to get to 400whp. I plan on doing this with e85. Don't know if the stock block would have trouble with 400 or if I should get a different block? Any input is appritiated

 

You will need:

(Dyno Jet no.s)

Open intake (AEM or similar)
1000cc inj or larger
3 port boost solenoid
Full open 3" exhaust / no CAT
255 Walbro
E85
Tune to 27 psi

Youre set

 

E85, manual boost controller, 3" exhaust, test pipe, 1000cc injectors, Walbro 255.

 

All the above + SD conversion. Stock block will take 400whp no problem, it's the torque you'll want to keep lower than 450~ ft/lbs. Stock rods don't like torque.

 

FYI SD conversion isn't necessary, if your on a budget.

 

Everybody's right.

With E85, it can be done with simply:

-Turbo Back Exhaust w/HFC
-800cc injectors (Although you should really just get the largest you plan to run for the future)
- Boost controller
- Intake
-Walbro 255

It can also be done on the stock downpipe and o2 housing depending on the tune.

Correct me if I am wrong, but I was told that the stock intake in the evo systems are not restricting at all? Was also told due to the nature of drawing air using the intake scoop and it being sealed to be kept away from heat was better then a open cold air intake.

Was just wondering if there was some light that could be shed, as I have a AEM intake and was going to back the stock intake setup.

 

Myself and another person I know made 400whp on the stock intake. I had a small cam, though. He may have also.
400whp on a IX is super easy.

 

My tuner had the evidence to back this up. The AEM delivered approx 15 whp more than the stock box (I dont even run the shielding). A true cold air box may yield more

He's the one who layed out the recipe noted above which yielded 407whp / 405 tq (Dyno jet no.s)

 

Instead of fixating on dyno numbers, just get an intake, exhaust and a 71HTA chra. http://www.forcedperformance.net/PROD/FPEVO971CHRA.html

Should be able to get ~370 whp on a good 91oct street tune. Best bang for the buck by a mile.

 

But he asked how to get to 400.

 

people are forgetting licp

crushed bov

megan o2 if you dont want an o2 dump

used s1 cams

 

no no no.. leave it stock

 

I think the lesson here is there's many ways to do it LOL

I have MIVEC cams that will help get you to 400. Greddy EasyCam, 264s, no need for springs and retainers. I made 450whp with them (slightly different setup). $50+ shipping and paypal fees.

 

I've heard that you should get s2 not s1
I don't really know the difference though or the hp gain from them
