I am on stock turbo right now...im about to purchase all the bolt ons that i dont already have and that includes cams. I have read every thread in here about cosi vs. s1's. But i cant find a definitive awnser. i dont plan on going to a larger turbo except maybe the green. So which cams do you guys recommend for me. This is such a hard decision. I dont want to upgrade the springs and retainers because i dont think it is neccesary unless someone can convince me otherwise. I have a IX too. loping or a smooth idle is not a concern of mine i just can decide on which is right for me...can someone give me there advice.

 

Cossie 272 make the same power as GS1 on a Green. GST Motorsports posted a log somewhere. I found it in my great cam search. Plus if you ever go bigger Cossie will be ok where GS1 will be maxed out. You do not need to upgrade springs and retainers if you keep the stock redline. A stock turbo runs out of breath and there is no need to go higher.

 

ok thanks but what about the stock turbo i said i might go with the green one day? Def nothing bigger so im mainly focused on the stock turbo and the green? Would u recommend gsc for stocker? Anyone else?

 

I ran HKS 272s on stock turbo and on my 37r, no problems and ran great!

 

you dont have mivec cams though...

 

daaaannng..i just noticed your setup....i bet you lag like a ****...and u cant rev it to high...stock block...your power band is pretty much unusable...id like to go for you to take me for a ride though...lol

 

ive ran GSC S1's, Cosi 272's, and tuned HKS...

S1's stock turbo = ok
Cosworth on anything, lots of torque more top end than HKS or S1
HKS just as much torque as the Cosi's, not as much peak, still much better than the S1's

keep in mind all of this is my own experiences with these cams and from the tuning ive done... Other people may have seen differences, but this is the trend i have noticed

 

Might lag some but I still rape FP greens down the track.

 

So cosi 272 ftw then. Anybody wanna sell me some now? lol
