I've been reading through trying to find info on the GSC S1s. I do not want to upgrade my valvetrain so was curious how beneficial these cams would be on an fp green setup.

 

I don't think you'll see enough results to outweigh the cost on the install honestly.

 

i was thinking that would probably be the case. i was hoping for maybe 25whp, but does anyone have first hand experience with these?

 

i saw more than that on a std turbo with GSC S1,,with no loss in torque ,,,so im guessing they must be of some use with the Green...........the graph is somewhere on this board,,im gonna have to find it and link it

 

If you're gonna do cams on an X, go big. Get some basic beehive springs for $250 and put them in w/ the head on the car. I wanted the S2's SO bad but due to no stock ended up with the Kelford 214-B's. I absolutely LOVE them, they improve spool/bottom-end so much its just amazing! These really really set off a bigger turbo on an X. Smaller cams or on the stock turbo I say meh--rock the stock cams. For as much work as it is to do cams on an X, go big.

 

Right, if you are going to get cams, you might as well go big. If you are out for a big turbo and 500+whp then get the S2's. If you have a milder turbo, then the Kelford's seem really good too.

I will probably rock the Kelford 214B's and a medium size turbo.

 

Would you guys who say the same for MRs? i.e. more aggressive cams GSC S2 or Kelford Bs for MRs?

I can't find any dyno results
