I have an evo and was wondering if I could get any more power out of the stock turbo and if yes then by doing what???
I already have:

Full exhaust (no cat), ported and jetcoated exhaust manifold and 10.5cm hotside,Ebay O2 Housing, 272/272 hks cams, valve springs and retainers, alky kit, ARP head studs, boost controller, dynoflashed, Upper and lower I/c piping, act clutch, fidanza flywheel.


what do you all think??? I've read about intercoolers but it seems that they dont give you that much hp on a stock turbo...I could be wrong though.

 

Aftermarket lifters and injectors.

 

If you already changed the 9.8 HS to a 10.5 HS, then you could change the VIII compressor housing out for a IX compressor housing. It would still be a stock turbo but you'd have an extra 15 WHP. You could also try any of a variety of hotter camshafts. Yeah, the intercooler upgrade could produce more power, even if you already are using alky injection. How much boost are you running? You can always crank up the boost a couple more PSI. And, finally, you can switch to an AEM EMS.

 

There have been some really high numbers with the VIII with either 280s or revolver cams. Maybe swap your 272 out

 

I'm running 26 psi I've heard its safe to run up to 28 but I'm kinda paranoid about it lol. Yeah the EMS would be awesome but just soooo expensive. 280 cams might be a little too aggressive for a daily drive IMO. I'll probabably do the intercooler thing I guess even though I dont think it will help that much. then look at the EMS. then a new turbo kit

 

I hope you have a fuel pump. I guess you foregot to put it in your sig.

 

yes I forgot to add that too...I'm glad I do...I might have blown up by now lol

 

What WHP are you currently at?

 

I'm really not sure. There isnt a dyno around here if I had to guess maybe 380-400
