Suggestions from the community on whats next 4 my EVO
Ok, I've got a full turbo back exhaust, boost controller and custom flash. I'm now off to Harmonmotive to get this puppy dyno'ed. Given the 91 octane situation, I'm probably lucky to get 275hp/275tq. Besides alchy injection, are cams the next best mod for me? Has there been a definative test on cam combos, and are the GSC cams the next thing, or does HKS still rule the roost.

I found out that running a 272 intake 264 exhaust will give you a good curve, and you won't need to use aftermarket cam gears to get it to idle right. Just a thought, and you could always upgrade that 264 later if you wanted to get the gears. The information that was presented to me was that the 272/264 is the best combination with the stock turbo and shooting for ~340whp. So, yeah...cams, fuel pump, intake, and another reflash to accomodate those mods - also might want to look into an aftermarket clutch to hold the extra power and a heavy duty kevlar timing belt to help prevent things going south really fast!

Most of the major vendors have staged upgrades which are great to follow, they've been tested and proven. I'm loosely following Buschur's staged upgrades, and I'd recommend taking a look at that, because right now you're essentially what they'd call "stage 1":

Good luck with whatever you choose

I would go HKS Suction Pipe Kit, and the GSC Cams...then I would stick some intercooler piping on their to quicken the turbo spool...The one thing that keeping the stock turbo, is with a few mods it will spool instantly!
