here's a link with some good info for throttle body size and plenum combo. personally, im going with an accufab plenum and 70mm throttle body. since you dont plan on supercharging, i'd say 70mm

FRPP 70mm T.B.comes with TPS so u don't have to tranfer or buy a new one

here's another link with some dyno sheets comparing different throttle bodies and plenums on a few differently modded cars.http://www.cnlperformance.com/plenum.html

It also measures less than 70mm.
Go with the best - Accufab, but be sure to team it up with an aftermarket plenum for decent results. Some reported a loss down low with the 75mm TB, so I went with the 70mm...and I have no regrets.

without a blower in the future, I'd go w/a 70 MM TB, but keep in mind you probably wont see/feel a gain unless you match it up w/a good plenum and maybe a CAI, and a tune. Pulleys are a good idea, too, but you might also consider a lower opening temp thermostat to make up for the cooling differences you will see when you add the pulleys in the desert heat
