I would remove the stock cat. That's a huge restriction...

"Anthony" is running a FP Green w/meth. If that's what you're running, it should be easy to get 400whp. And he has an VIII

"05 Evo VIII
Fp Green 28 psi w/meth 431AWHP / 403 AWTQ"

Also, from what I hear the GSC S1's are making more power than the cossie's for smaller-ish turbos

 

+1 on that. Why do u call up Tuning Technologies to find out what u need to do to get 400awhp with ur 20G

and 3000ways, I think it's www.tuningtechnologies.net now, not .com

 

He said he wants streetability over track. It's hard to DD without a cat.

All bolt-ons and meth should be more then enough.

 

Im hitting 400 whp and torque on the stock ix turbo on 28 pound spike with ZERO knock. Meth is a beauty

 

u put cams on the car and it is going to idle like ****

 

cosworths are decent. streetability stay with 272s
GSC makes good cams as well.

up the idle a couple 100 rpms and it wont idle badly at all.

untuned yea they suck but with a good tune theres no problem with them.

 

Just hop on a dynojet!!

 

Cam idles really depend on the type and the tune. Not all make your car idle unbearable.

 

mods in my signature put me over that mark on a low reading mustang dyno

 

Mine has Stock Cams, full exhaust, Intake, UICP, LICP, AMS IC., BUSCHUR Ported and Coated Manifold, Injectors, fuel pump, 02 Housing, meth. kit, Exedy Twin HD, and Tuned by JESTR.

 

Second that i was talking to Buschur and they said that for me to get up to 350-400 WHP all i need is a 20G, now they also said that if i decided to get a 30 or a 35 this power would be made alot easier, but the 20G would get the job done for a more economical price

 

so cosworth then? and after my retune ill be right around 400? and if i tune with c16 ill be way above.

 

OK so I just picked up my 20G and I was thinking I was going to be able to get over 400 with just the turbo and my supporting mods. I currently have:
Hks 272
AMS IC, LICP, UICP
Invidia TB exhaust and downpipe
HKS Intake
AEM cam gears
Perrin MBC
XS Power exhaust manifold

and now my 20g which is not installed yet. So am I going to get above 400 or not.

 

you will be close
