I am looking for a 90mm throttle body for a LQ4 swap with L92 heads and the LS3 intake. I want to keep it drive by cable and so far i have seen the Holley sniper but it looks like you have to use their IAC and TPS. Anyone use this product or is there one that you all can recommend?

I only see 92mm from Warr Performance. I was looking for a 90mm will it make much of a difference if i use 92mm?

No. It is a c*nt hairs difference. I have one on my ported TBSS intake, and I am ordering another for another stock TBSS intake.

Whats everyone's thoughts on the PCV? How would you run? With it or use a breather?

Why wouldn't you use it? Look at my wagon's LS1 - it has a fully functional set of emissions controls.

That is a different question. I have one without and had to source the fresh air forward of the TB but behind the MAF because it is metered air, and as part of a closed loop system it must be pulled back around through the crankcase and back into the intake. Mine comes out of the valley cover PCV into a catchcan.

I also just relized that there is no cable braket for the LS3 intake. Anyone know of where to get one that will work?

Use the truck manifold and adapt one like I did. It is a better intake anyway.
