Hey guys, I'm considering getting a new turbo/manifold for my car. I'm currently running a T3 super 60 at 9psi, but it's a little big for my kind of driving, it's got all kinds of top end power (unfortunatley the ECU cuts fuel at 115 with no way to remove the limiter short of a stand alone fuel managment system), but doesn't start to spool until around 3k rpm. This kills me from a light, and I've been thinking about getting into auto cross, so I'm looking for something that might spool a little quicker. Anybody got any sugestions?

PS, I'm running all this on a 4g15 engine. 210cc injectors (will upgrade to the 290cc's I've got sitting in the garage if/when I replace the turbo), AEM fuel pressure regulator, 4g93 (1.8 mirage motor) throttle body, ported intake manifold, 2.25" intercooler piping, Evo VIII FMIC, Hallman MBC, A'pexi SAFC II, and a 2.5" exhuast

 

Hi,
I'm not familiar with the 4G15, but I can tell you @ 9psi the turbo your using is being wasted. Have you considered a big 16G, or a T04B 50trim? Also you'll spool more quickly if you upgrade to a 3" exhuast
