Default Will 102mm throttle body fit on 90mm LSX intake?
Looks like I am going to have to buy a new throttle body, so I am thinking of going with the 102mm, if it will fit on my 90mm LSX intake.

Yes and no .. Youll have to port your 90mm opening a bit to get the blade to clear

damn. I was hoping I wouldn't have to remove the intake again. Maybe I'll just look for a NW90mm.

We also make an adapter that tapers down to 92mm. Direct bolt on solution.

Wouldn't just buying a 90mm TB be easier?

I assume this moves the throttle body forward enough that the blades will clear a 90mm LSX manifold?

I want to switch to an LS7 style MAF and 4" plumbing, so the 102 mm TB would eliminate the need for 4" to 3.5" couplers.

Plus, I can't find new 90mm NW throttle bodies.

I looked at them, but there are too many reviews about products that do not line up right.
