throttle body size
I have just recently purchased a trick flow upper intake plenum for my 02 gt and was wondering what size throttle body would be best. It says it can take a 70 or 75mm but Im not sure which would be best. I would like to get a ford racing tb, but I cant find a 75mm and that is what I wanted. If i go 75mm what would be the best tb to get. O yeah I also wanted to get the intake plenum ported if that helps with the decision of the tb. Thanks in advance for everyones advice.

Well, what are your plans for the car. If you think there is even the most remote chance that you will go with a supercharger, then get the 75 mm tb. If you are going to stay N/A, pick whichever you find cheaper. I picked up a FRPP 70mm tb for 40 bucks. Cant say it did anything by itself, but Im going to be getting a plenum soon. By the way, how did you like the gain you got from the plenum, anyone notice anything? I need some torque, will I get any?

I noticed a pretty good gain with the plenum and tb. It's more responsive and I gained over 2 tenths in the 1/4, and that was with the stock paper filter, and air box. I haven't ran it with my CAI on yet, but I bet it would have gained even more.

The 75 will flow more, therefore making more hp. It will prolly be about 2 hp more, but if you are after every last hp for your street car, and might do a blower in the future, just go ahead and spend the extra 10 bucks for the 75 mm. Neither tb will hurt the performance, but dont expect anything phenominal.
