I have been looking forward to change my cams.
Now I currently have 272/272 HKS cams with FP black and it runs around 430 hp.

Im now thinking about GSC S2 cams (274/274)
but I was wondering it might lose the low end.
Right now my turbo kicks around 4400 rpm.

To be honest I do not exactly know what GSC S2 cams would improve my car. Would it not lose the low end power and how much would it increase the hp and the torque? would it be able to hold more boost on my car?

Please help me out!!

 

Searching is helpful. There are atleast two back to back comaprison of hks 272 to s2s...

and since I'm feeling nice today:

S2's are a wayyyy better cam then the hks. Id switch the the s2 ASAP

 

I have same cams and am switching to S2 by the end of the month. Looks like no low end power lose and slight mid lose. More top end. Ill let you know my findings after Im done.

 

fp red and stock cam was 3800, fp black and kelford 272 was 4200.

 

Are you using stage 2 beehive valve spring or stage 1? so you dont lose any power at the low rpm right? I have the stock motor right now by the way

 

I have supertech dual springs with titanium retainers already installed

You will loose low end power period.
I would not trade loosing 10hp/tq down low where I use it everytime I shift for 20-25hp/tq up top where I rarely take my car. Well maybe a couple of times per week but still it's not worth the trade off unless you're a hardcore racer.

 

Those s2 cams ams used I believe were the old style with less duration. The new s2 cams are better as seen in 2nd post link.
