You really gon rev that motor out wid them cams?? You got a 2.5 on there?

Them cams dont go well with that size turbo if on a 2.5L. We done up a STi wid Crower 264* on that same turbo kit and turn up 500whp on DynoJet. On mustang it wudda done up 470whp had it not been spark blow out. We were runnin on E85 here on this setup.

Yup Fuji is correct on that. I think 450 will be a bit hard running pump gas.

a few things.....




1. bc 280 cams and springs - 264* for GT3076
2. tgv deletes - plug them good
3. 850cc injectors - maybe look at the 1000cc top feed kit
4.perrin gt3076 rotated kit - save a little more foro the 35R if that's what you want
5. full straight pipe exhuast - as long as it's 3", that's all that matters
6. turboxs fmic - you gone need one with good end takes like APS's big FMIC if you go 35R
7. wiseco forged pistons and rods - You gon run 8.9:1??
8. turboxs utec - What you gon do that? reflashed ECU works well.
9. unequal header - Which ones? Better not be aluminum foil. needs to be thick pipes
10. soon to have aem meth kit - you aint got E85 there huh?

I'll still say those 280 cams would be a bit too big... Hmmm, go with some gsc 272 cams or kelford 272 cams and you should be fine with a 30r on or a bigger turbo on later down the road.

Why are you guys keep saying that the cams are too big? what is it bad? He is going to make more power with bigger better cams than with small cams

With the cams and mods you have (if your not hurtin to get your car back for a DD) just save and wait another couple weeks and try and get an HTA 35R - especially if your not doing the work yourself. I built my motor with cams, pistons, rods, bearings, etc, and then put an HTA Green on the car. I wish I had just waited another couple weeks to save and put a 35R on the car. However, financially this was not an option for me as I needed my car back for daily transportation. Sounds like your in the same position as I was. But in the long run, if I was able to be without my car for another couple weeks (which I wasnt) I would have waited for a EWG'd HTA 35R. If you can do the bigger turbo go for it. Even if you can't though, its still gonna be a fun car with the 30R.

cams go with powerband produced by turbo. So if the 35R is in mind later, then they are fine. I choose cams that will give me the widest powerband without losing too much down low and still hold power from dropping off up top.

This is true but by how much?? In EVOM they use 280 and 282 with stock turbos and they work perfect. Next time I have to open my engine, I will be installing something retarded big GSC 282 or something big from Kelford

The EVO's are a 2.0L. That focuses the powerband more up there where the motor needs to rev so it can make power. They DO have a turbo that's quite large from factory. Damn inline engines....

Thats is what I am asking: how much it will hurt, and I am sure no one really knows . Is probably a few rpms, while the gains could be substantial and they should be substantial

450HP is very doable with the right parts and proper tune. 35r is not really needed unless u really want that turbo. u don't need meth for that level.
