I've done alot of research and I still don't get a clear answer. I know it will be laggier than stock turbo, but I would like to get the quickest spoolup with the red out of the mods I have.

The current mod list is(Evo 9 MR):

Perrin TBE
HKS Intake
Reflash

Current WHP: 365 @ 27psi

Will Add:

ETS 3.5 FMIC with IC pipes
FP RED
880-1000cc Injectors
CAMS: ???

Goal: 430-450WHP

I'm leaning towards GSC S2's from what I have read, but I would like to get some feedback from you guys . I'm willing to sacrifice some power in order to get better spool up. Also if there is any other supporting mod you guys think I should add, let me know! Thanks in advance

 

I have and really like the S2s....other people go with Kelfords...whatever floats your boat I guess....

 

I run kelfords and love them

 

From what I gather on the forums u can't go wrong with either the s2 or kelford 272

 

both are good, depends on the brand you are leaning on

i hv GSC S1's loving it... may go for S2 for nxt upgrade

 

In addition to the FMIC and hard pipe kit, port your ex mani, get a larger o2 housing, port the head, all of these items cotribute to quicker spool.

 

a 02 housing, ported head and ex mani shouldnt be a necessity. Honestly you wont notice that much of a lag diff between the red and stock turbo. also have you looked into the Buschur 272 i have heard they are great cams also

 

+1 for the GSC S2's

 

+1 on everyones quotes except this one, come on guy yes you will notice lag going from a stock turbo to an fp red, as for the cams, i had kelford 272, but also heard great things bout s2 cams, im personally going with S3 cams on my current build, just don't forget to purchase valve springs and retainers to match the cams, otherwise you won't beable to fully extract the cams potential. Also i saw your list of mods and noticed no fuel setup? you'll need a bigger fuel pump, the 880cc should be fine, good luck.

 

i love my comp 280

 

I run the Cosworth M2 cams with my FP Red and I love them!! I made 470/450 at 27psi!!!

 

Kelfords here. Very happy

 

you want top end powa

I forgot to mention I have a walbro 255 installed . Also, I'm planning on upgrading the valvetrain too!
