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.

 

Get a fuel pump, and cams. Both hks/gsc cams have been proven to give great gains. What cams/and duration is up to you, either way you cant go wrong.

 

Yup.

 

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!

 

intake

 

Driving school.
Alot of the weak points of the Evo is between the Momo steering wheel and Recaros.

 

I am with him fuel pump, cams, with custom tune. That would be the most bang for the buck. You do not need a intake unless you really want one. The stock airbox is fine.

 

Get intake and GSC cams, you will unleash a whole new car

 

stickers... lots and lots of stickers.. you want a fast ride... well then you need stickers...

 

At that point, I put in a fuel pump and upper/lower IC pipes. I just bought 272 cams + gears, and hopefully they'll be in by this weekend.

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

 

sweet I hope you get them in before the BBQ.

 

Yeah, me too. Maybe I'll have them work on my car while we're eating

 

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!
