Hi i have a 2.0 evo 9 with:
aftermarket rods and pistons.
built head(272 hks cams etc)
35r kit tubular manifold w/ 3" downpipe
ams fuel rail and 1000cc injectors(for now)
ets 4" speed density intake
im at 26psi and dynode @ 460awhp-350tq on mustang dyno.
I know that e-85 would be the best bet for hitting the higher hp but i don't want to have e-85. Im wanting to get around to 600hp and this is for street use only and having fun.
So heres what i had planned. Get s2 cams, Port intake man. and TB, get bigger injectors and possibly bigger than 255 walbro. And finally getting a meth kit. What do y'all suggest.

 

Do you have E85 in your area?

What 35r is on the car now? Cast compressor, gen1 or gen2 gtx?

The bottom end should be good to at least 9k as long as it was put together correctly. I'd put S3's in it with appropriate springs and let it eat.

A Magnus V5 and appropriate throttle body would help as well.

 

i purchased this turbo kit from AMS like 7-8 years ago and i don't remember which one but i think the cast compressor and its a precision turbo. And i do but i don't want e-85 its like 20 min away and i want to travel in the Evo. I agree with the magnus V5 it is a badass manifold. I heard that the s3's were for the 1000hp range.

 

S3's are for an RPM range. a 35r on a 2.0L should be revved to at least 9k for wider useable powerband, S3's will help with that. Having Mivec will mitigate most spool up loss vs the S2's and you won't even notice them.

If the turbo has a cast wheel, I'd highly recommend going to a modern billet compressor turbo. A Precision gen2 6266 or Garrett Gen2 3582 would do fairly well. The 2.0L with T3 open flange (assuming its that since the kit is old) will hurt a bit for spool, but both of those turbo's likely won't feel any more laggy than what you're at now.

The cams and manifold would likely get you to 500-525 on the current turbo. A modern turbo would get you around 550whp on pump gas, then you can add a bit of meth for additional fun. I just did a 2.4LR with a 6466 that made 560whp on ACN 91 at barely 23psi of boost.

I would get Injector Dynamics 1300cc or Fuel Injector clinic 1200cc injectors (they're both rated for over 650hp on gasoline) and go to a walbro 450 fuel pump with hi/lo voltage rewire to ensure you have enough fuel.

 

don't see intercooler nor have you listed exhaust mods

 

haha i overlooked them. I got ETS 3.5" and HKS TB exhaust.

 

E85, E85, E85,E85
Bigger injectors, pump, ethanol sensor, full flex fuel tune, and E85. With the flex tune you can just run 91/93 pump or whatever mixture when you "travel", unless you think you really need all 600whp to be available on your whole trip, all the time.
Did I mention E85?

 

Thanks hokiruu yea so if i get a flex fuel tune with say.. 2150cc injectors then i could run those injectors on pump and it would be fine?

 

For e85 you'll need 2150's and a double pump setup.

And I would still do the other supporting mods, camshafts at a minimum.
