Throttle Body & Spacer? 65 or 70mm?

oo-gonzo · 10-04-2006, 10:00 AM

Hi, just a question! I have a 93 GT. It has a new typhoon upper & lower intake. I am looking at TB's and spacers! What is the difference in HP and performance from a 65mm TB and a 70 mm TB. Reason: Found a great deal on a 65 mm, but was looking for 70 mm. If there isn't allot of difference between them, then I would rather go the better deal route, for money sake! Thanks! Gonzo

If you are mostly stock (heads & cam) then I would do the 65mm unit.

65mm TB has alot of potential. Not much difference to a 70 for a street car.

I agree with the above. You'd have to have some really good heads and a healthy cam to see any difference with the 70mm. You should be fine with the 65mm. . . especially if you can get a good desal on it
