its a very nice setup bro. But with all that it really depends how the tunner is but over here a setup like that with pump and meth will make over 600 like 28-30 psi and very safe. So u wont be dissapointed at all and will be a mid 10 sec car in the 1?4 mile with good driver!

^ change out those small cams and get GSC S2s. On my car I went from HKS 272/280 to a custom GSC cam and gained 90hp.

Was that with the stock turbo?
If not what kind of gains would that be on a stocker?
How rough is the idle with those?
And IIRC you HAVE to upgrade your valve train with those correct?

 

No that was on my Black. On the stock turbo HKS to S2 you will see 20hp. Idle on the S2s are not bad at all. You can find videos on youtude. My custom GSC cams are a bit aggresive, one of the most aggresive on the market and my idle isn't that bad but I'm also on a 2.4, not a 2.0.

Yes you will have to get springs and retainers with the S2s. It is worth it though. Good luck

damn my hks 272 r pushin my evo around makin over 600 whp pump gas i was thinkin about the Kelfords thoughh.... but im happy with the HKS's

 

wats u guys.. havent dynoed my car yet but got a street tune till i get to do sum dyno time.. just wondering if u guys might know from experience and knowledge wat kinda power i might be putting down.. my mods r on my sig. and im running 28 psi on pump..

 

Definitely agree loose those bumpsticks and get some bigger ones. Lose the injectors for some bigger ones or pick up WMI. I would definitely do some WMI but thats personal preference.

 

Ill play haha

thanks peoples !

 

single 255 and 1000cc injectors are going to stop you at 500awhp on 93 octane.

 

400ish with 93/meth with the stock cams holding you up, no mention of injectors

 

not much data on that turbo, I'd guess 400 possibly. Hopefully you just forgot to mention the walbro pump you're going to need
