Best Cam match for a Evo Green?
Your profile says you have a IX, so most of the suggestions that have been made are not applicable in your case. (Lucky for you, you couldn't install the Revolvers if you wanted to.)
If you do have a IX, the Cosworth and GSC cams have been proven to make good power. My suggestion would be Cosworth, especially if you're looking to go with a larger turbo in the future. Have fun.

Juns don't seem to work (friend of mine w/ Green is pulling his 272's out now)
On an 8 HKS 272's & GSC's & whatever Buschur is using seem to work best

Not to thread jack, but I wanna pose a question to the Evo owners who actually have these various FPGreen with "x" cams set ups, that I'm pretty sure the original posted was looking to have this answered as well. Here's a little background as to why I'm posing this:
I remember driving a customer car a while back (98 gsx Stock 2.0L 6bolt, with 8.3:1scr pistons, stock head..hks 272's and an FPRed). This thing made tons of power, but only in the very upper rpms. The Red wouldn't reach peak boost until about 4600rpm, and with the 272's shifting the powerband upwards, this thing was a dog at anything below 4k, but then a rocket until redline. I pulled him time after time with my dsm (FPGreen/264's) Although he made more power..422awhp vs. my 392fwhp. I credit this to the fact that I had a very broad usable powerband. While he made more up top, my car was in it's powerband alot quicker, and remained there until redline. At the same time, my car was friendly to drive as a daily (4th gear, lo-throttle passing was easy, etc..). Enough rambling on, I think you guys should be seeing my point by now..
Wondering if it's any different in the Evo world as far as cam/ turbo mating. I'm assuming with static compression, head flow, etc..being similar to the 4g63's of the dsm era, it shouldn't be. I think the original poster as well as my self are looking to see what cams behave well with the Green on a daily driven vehicle?? With full boost being reached on the Green below 4krpm, I'm assuming that a high lift, long duration camshaft like a 272-280 wouldn't be much of a problem, considering the turbo will be making power below 4k correct?

I am not an engineer, but I think the GSC S1's with a combination of slightly higher lift on the exhaust side, with a little less duration are a good combination. You could also try some very high lift, lower duration cams like the Piper rally cams, but then you'll need new springs and retainers. Everything is a trade-off, you just have to know what you want.

The Gren is the smallest turbo up-grade for the Evo, so keep in mind, higher duration cams could out flow it, just like it does to the stock turbo to an extend.
Any other Cam brands I am not familiar with, but they should permorm similar.
Mr. Buschur has posted some info on what Cams not to use on the Green. Try a search for that info.
It's just better to show dyno charts and let the end user decide what works best for them. There is no perfect answer.
Like I mentioned earlier, there are trade-offs for everything. I have seen many torque deficient cars running the 280's. Good on the top end, not so much on the bottom.

Fair enough. Read 'em and weap:
Just want to pass along my good experience to others. I installed my alky kit at the same time here, but I'm only running about 1.5psi (peak) more than I was before...I've posted this elsewhere tho.
At the moment I'm goin for a solid daily driver with 400-450hp With alch injection, 91 oct ported everything and built top end. What have people seen with Revolver, Cosworth, GSC, Tomi ( meh) ? Any info with dyno sheets would be awesome. At the moment I'm thinking Revolvers... 
So, are you already running the Green? In your mod list, is that a ported housing on the IX turbo, or is it on the Green? I wondered, because, I'll bet your car is pretty quick with the ported Ix turbo, as is? And if you added meth and cams, you should be able to achieve your HP goals w/o needing the Green.
You should see more of a power boost either from the cams or the meth than you would from upgrading to the Green. Why don't you try maxing out the IX turbo first. Maybe it'll be good enough.

GSC S1's should be awesome with the FP Green. I've seen the GSC 280's (now S1's) produce some great #'s for both torque & power and nicer spoolup on Evo 7 & 8's .
If you have an Evo IX the toss-up is really between the Cosworth & GSC S1's as previously posted by other members....both work great.
