Very helpful thread. Im going on a mssion with my TB. I'm a make it work, though. I'll be sure to come back here and post my results.

I'm probably getting the ford racing gt500 throttle body. Expensive but maybe worth it after I put on headers.

I gained 11rwhp with a TB swap. I've since gone back to the stock one because I'd rather walk a 400-mile road trip than drive a Mustang with an aftermarket throttle body. They are all crap when it comes to drivability, regardless of how much you try and tune them out.

I had a GMS twin62mm

for you guys who are contemplating a larger TB a cheaper route may be to pick up a unit from a 6.8 V10 (60mm i believe) and a cheap billet spacer off ebay. I think I was in mine a total of around 100-125 bucks.

To get it to fit I had to do a little dremel tool work on the spacer and on the bolt holes in the new TB, and use a "fernco" piece of rubber to adapt the larger inlet mounting flange to my CAI but in the end it worked perfectly and did not require a retune. I *think* the idle is slightly higher, maybe 50-100 rpm over stock which hasn't been a problem at all with my automatic and honestly now that it's been on for awhile I haven't really noticed it.

Did I pick up an increase? Who knows, I installed my CAI and tune at the same time - but I doubt it hurt me and it's just 1 more mod done to the car

btw this is for a GT not the sixxers obviously
