Larger TB for FI

[american thunda]

Hey guys Im thinking about adding a 58mm Tb to my car but wondering what type of gain would i get.I know most Na lt1 s get a 8-10hp gain by adding a Tb. I was just wondering if a fi car would get a larger gain. A larger tb would be pretty much my last mod i could do to my car before i went into the motor. My car has a p1sc procharger on it with the stock Tb. thanks

unless the intake or heads are worked, and unless you have some better exhaust than stock manifolds, there will be virtually no gain from adding a bigger TB. The whole setup needs to be bigger and flow better, not just the TB or just headers.

Every little bit will help. I wouldn't say that adding a 58mm TB won't give you any more power, because it will. But as QC97Z pointed out it will take the complimenting of several other aftermarket parts to see the full potential gain from the larger TB, like heads, exhaust, cam, intake, ect.
