like the title said which one do u guys preffer?..im in the market for cams?.

 

I'd wait for info on the GSC S2's. GSC has S1, S2, and S3 cams now. As far as I know they're not going to be selling cams listed by the duration anymore.

There's quite a bit of info about the Cosworth cams, and some about the S1's. Id contact GSC and tell them what you have, what your plans are, and go from there.

 

Supposely the cosi's are better than the gsc 280s. However, it is a toss up between the gsc s2 and cosi's. But if your using the stock turbo then its s1 and cosi's.

 

....

 

what are your mods and maybe i can help.. check out our gsc motorsports section of evom for the S1 results tha t machines gone wild did.

 

Here's the site good gains don't know if its whp or bhp https://www.evolutionm.net/forums/sh...=1#post3856389

 

This is kinda the grudge match that everyone on here has been talking or debating about. GSC or Cosi....Which one is better? Which one nets more power? It will be nice to see when they release the test results for the back to back on both. IMO I dont think you can go wrong with either.

 

Just depends on what you plan to do stock turbo s1's upgrade then maybe the cosi...

 

i have works dp, works rtp, hks exhaust. and a works flash. and getting a O2 housing and a ported manifold, arc intake, greddy uicp, ams licp.

Why? how much experience does Cosworth have with 4g63 motors?

How much experience does GSC have with the 4g63 motors?

If we all drove Ford's I'd say Cosworth all the way, but that's not the case...

 

LoL well cosworth makes a race motor 4g63 and yeah...

Gsc cams sound great too you just have to look down the road and see what mods you plan on doing... S1's for stock turbo and cosi for antthing besides 30 and 35 if you have those the s2's are more aggressive and should out perform the cosi

 

Chrylser could make a 4g63 race motor. Doesn't mean they have any experience with it. I'm not saying Cosworth stuff sucks, from all accounts it's pretty decent. Is it worth the money? IMO nope.

It just seems to me that Cosworth needed to branch out into new markets to recoup money they lost in building a temendous failure of an F1 motor, among other things. They have such a high overhead, which is why they're stuff is so expensive. My point was, when it comes to knowing the ins and outs of the 4g63 motor, there is no replacement for experience. One of the reasons why I trust Dave Buschur's word over ANYONE, well, I'll throw Jun, or Garage HRS in as well, but I look to who designs and builds the fastest, strongest, most reliable 4g63's when it comes to parts.

Cosworth is an impressive name in racing for sure, but, look at the fastest Evo's and DSM's. Cosworth isn't mentioned. They may in the future, but I'd look elswhere until their parts are a little more proven.

This is all IMO of course, so take this rambling FWIW.

 

It seems like everyone is saying that if you have a 35R that the gsc s2s will perform better than the cosi's?
