It will definitely be easier to reach that goal with a built block. Even with an FP Black or 6262 and some s2's I don't think you'll reach 550 on pump..assuming you upgrade the injectors as Gypsy suggested and go with a fairly aggressive tune you'll probably be somewhere in the realm of high 400s or maybe even low 5's.

A friend of mine had a very similar setup to yours with ID 1000's and an FP Black (he also went with the HKS 272s) and his X put down 490/378 on pump 92 @ 23 psi. Then again every car is different and a lot will be determined by the tuner (especially if you want to preserve the longevity of that stock block) just don't get your hopes up!

As far as injector size goes, take Pacent's advice. If 550 is as high as you'll want to go FIC 1050's or 1250's should probably be okay I'd ask your tuner what he would be most comfortable with...if you want to leave some breathing room maybe go with 1450's.

 

ID1000's will def support 500 whp. Meth injection doesn't have too much complexity and will allow you to run a ton more boost while substantially lowering intake temps.

If you go with the FP turbos, make sure you do research before buying it. You will need to buy the high performance feed line and use a specific oil (ams oil)

 

really, why is that? i had a fp black on my last evo and it never gave me no problems as far as which oil to use... but i will look into it amsevo6975, thanks for the advise guys...

 

well lets just say, if you follow those directions its basically for the warranty for the turbo you buy from FP

 

I have 800whp evo's on stock ecu as do many other people who tune evos as well.

you also don't need to port the head to achieve 550whp on 93octane fuel.

The MAF will support a hell of a lot of power as long as the person tuning it knows what cap limits to remove in order for it to keep up with the airflow passing through it. if you overrun the MAF (which ive yet to see), you can use speed density with the stock ecu. people have made 1000whp dynojet on the stock ecu.

 

sir shiftalot it will take a really expensive setup to hit 550 on the stock frame turbos with just 93octane.. you would be much better off going with a t3 setup, such as the FP HTA3582/86 or a 6266 precision based setup.

If you do meth injection, then that's a different story.. then you will hit your goal, but you're still going to need better supporting mods..

to name a few things that will get you there:

non restrictive free flowing TBE
good cams like kelford 272, gsc s2/s3
non leaking bov / tial, forge, etc
fic injectors (wouldnt go lower then 1000cc for room to grow)
walbro 255 (modify it by punching the relief valve for alittle extra flow)
better fmic = br race, vrsf, ets, etc
port the intake mani and exhaust mani
clutch that will withstand the power.
65-70mm tb will help also

if you add meth with enough cc's in spray you will get your goal with a stock frame turbo.

most people these days just go with e85 and have 2 maps one with 93 one with e85 that way they can switch off and on when need be.

just do a lot of research and you will see what is best for your setup.

 

I've got pretty much the same pasts as you except s2 cams and unported head with a 6262 made 500 whp, that lasted for about 20k miles lol. its gonna be hard to hit 550 on a stock block & u might as well build it while its all apart instead of having to pull it apart in 12 months. O hand im running 1050cc.

 

im going to ask both of you gus this because i actually plan to do something similar, and same car.

what all would you reccommend for the drivetrain for supporting that? mainly the transmission. i hear so many mixed results that the tranny can and also can not support that power.\

any REAL ideas?

 

I run a stock tranny with an Exedy twin with my setup no issues what so ever. And I know I was in the 500s with pump gas with my setup. Maybe Tom can pull up a graph for you.

 

thanks so much fr getting back to me so fast.

i have no idea why its like that, is it common on here for people to talk crap about the evo1-9 trannys?????

 

 

Well the 8 and 9 trannys are pretty stout. I don't know much about the 4-7 but I am sure they were evolved to what they are today. The 1-3 were pretty much like the dsm trannys, they were kinda weak and needed some help.

 

I agree with everyone about pump gas...it's garbage. It will be difficult to reach. Get a dual map put on your car for pump and e85
