Using an LS3 Intake for Boost, which TB? 90 or 92?

Hey Guys,

I'm doing a blower setup on my car and I'm going to use the OEM LS3 Intake. Anyone know what diameter size is the inlet? 90mm? or 92mm? what TB size is best to use for boost, if the opening is only 90mm I think a 90mm TB should do just fine with boost right? My intake is on the way here but before I buy the TB want to know exactly which one to buy.

Thanks

Kamil

Stock. Use the stock intake and stock throttle body.

I'm going to be running a NW 92 on my boosted setup. Healso makes a throttle cable bracket to fit his TB which you need because the ls3 intake doesnt have a provision for it.
