Is the difference between 70 & 75mm TB's noticeable?

Stang_ROTY · 08-15-2004, 12:53 PM

I'm going to the Victor Jr. setup and I was wondering if I really need to spend 300 bucks on a TB that is only 5 MM larger than what I currently have (I have a 70MM TB ans EGR spacer now). Is the difference going to be worth the money?

I should note that the opening on the Victor Jr. EFI is 75mm.

No need, too big will just kill you on power.. the 70mm is fine.
