i know that my top end is not really the greatest. since i have the greddy kit can i buy a 18g from the b16 kit and bolt it into my setup?

 

Nope, I just called and they said I would have to get the manifold and the TD05H-18G.

 

Hmm.. being a Mitsu turbo, what is the turbine housing on it? a 6cm squared? If so, I would think you could port the manifold to a 7 cm housing, and use a 20g, skip the 18g.

 

how does anyone feel about this?

 

I feel you should do it if it is a mitsu exhaust housing...

 

if you go to http://www.forcedperformance.net/subaru_turbo_fp.htm
you can upgrade. i emailed them and they say it can be done with the greddy 15g. it's an 18T, which flows a little more than the 15g. or you can find a place that can upgrade your turbo to a td04h-16g, which is the turbo that is coming out on the new neon srt-4

 

yes they said they could put in the 18T wheel and clip it for 600 (including the rebuild) I thought that was a little steep. Anyone else?

 

i'm not sure. other upgrades are just about as much. my biggest question is how much power gains can be expected on top end. also at what rpm boost begins and when it hits full boost. anyone?

 

i think i am going to wait untill the turbo takes a complete crap on me. I am using the stop map sensor so goign over 13-14 psi is the limit for the sensor and the turbo. sounds like i should just stay under that. 12psi daily sounds like a good number to me.

I dont know any specs on what the rebuilt turbo would flow. but he said he does the same work for wrx guys, so i imagine lag would be a bit more than i want.
