FasterProms has cores available.

Give them a call or email, they can send you a ported TB and then you send back your stock core for credit.

No down time.

PS, to answer your exact question, you need a 90mm, drive by wire tb. G8s and Corvettes use them also any LS2 powered car. (ie, 05-06 GTO)

I would guess Pace would have one you could buy to get ported

Honestly, if I wasn't going to do a core exchange, I'd be calling junk-yards.

Ha I always forget about them...doesn't Fast offer a ported TB?
If they do is probably cost $$$

I don't think they've built too much that isn't based on the old LS1 & requires adaptation to fit anything newer than 2004.
The FAST intake to fit L92 heads has been coming "next week" for the last 2 years.

No, FAST only does cable driven TBs, no electronic yet.

Ls2Portworks usually has cores, too, and does a good job

I've got one here on an L76 crate engine that is surplus to requirements.
I'll remove it and work out the postage to USA today.
