I'm getting close for a timing belt service and thought about cams since its already having to take the T-belt off. I only have TBE, intake, and a tune. My plans were only where I am but decided I may want a little more. I have a 5 percent chance of ever changing turbo so I'm not looking for major power but cams that would be worth the time and money. I wouldn't changed springs, valves or nothing so just looking for good cams that won't require head work. But I am looking for the absolute most power cams. What are your opinions or suggestions?

Edit: by the way my evo is a IX

 

Well if you want the "absolute most power cams" I am pretty sure you are going to have to change out your springs and valves. I would just check out this stikcy here https://www.evolutionm.net/forums/ev...no-replys.html that will pretty much help you figure what the most aggresive cams are without having to change anything out.

 

You're not going to find "maximum power cams" without upgrading to at least a better set of springs....period. now, if you want decent power without upgrading anything other than the cams and not have to worry about valve float, go with either some gsc s1's or cosworth m2's. The way I see it though, you might as well throw some springs in there while you are doing the cams and get a nice set of kelford 272's or 280's. Do it right once.

 

I went with the GSC S1s and absolutly love them! They do not require upgraded springs and I picked up an additional 24 WHP with them with similar mods to yours. I will side with BenJ tho if you are even thinking about ever upgrading in the future go with the springs right away.

 

Forced performance 4rs or cosworth m2s

 

GSC S1 or FP 4rs would probably be your best bet

 

im running hks 272's and love them. i would recommend spring upgrade tho.

 

i would do gsc s1's............

 

Without a doubt go with kelford 272

 

I have a fully built evo making over 600 easily and my HKS are great! nice sound even on my AEM. Thats my choice

 

I did HKS 272 cams but would do GSC S1 if I had it to do all over again for sure.

 

to each there own but i got the kelfords 272, drivability is great!

 

i'd do gsc s2 cams....

 

cossi M2's worked great for me and by the way woke up the top end on the car on stock turbo IX

 

Of all the cams we have tested for the IX's the most power has been S2s, but not everyone likes to do valvesprings because of the budget needed. You can get away without doing them but we do recommend them.
