Throttle body questions...

Hey guys - I've been reading through all the threads on the injector swaps and intake swaps (4.0, btw) and wondering, what throttle body is everyone running? Stock zj? WJ? Aftermarket? I've read that the TB spacers really aren't worth the money, but have seen something about a 62mm (correct my numbers if I'm wrong) TB. I'm planning to do the 703 injector swap, 99+ intake swap, and possibly a header all at the same time, and would love to go ahead and change out the TB if necessary.

If the motor is stock, I wouldn't worry too much about it, but if you are stroked, then yes, a larger TB would be beneficial.

Isn't red the only color a vehicle should be?
If at first you don't succeed, use more speed.

I ran a stock one that was bored out to 60mm with a 99+ intake, header, cam, etc. Every little bit helps. I wouldn't waste several hundred $$ on a BBK, RE, HESCO or other name brand TB though, a stock one bored out achieves the same result.

Stock ZJ, not stock WJ, right? This something you did yourself or send it out to a shop? I know I'm not going to pull too much power out of stock 4.0, but like you said, every bit helps.
