whats the difference between 52mm and 58 mm??????????

i was looking to upgrade. i have a lowtemp thermo, catback, and cold air intake already. worth it or no?

cars a 95 z28

 

Umm...the difference is about 6mm

In all reality a bigger TB isn't going to help you unless your over 400 HP, don't waste your money until you start doing some internals.

 

no not if thats all u have its not going to help enough to pay ya back for the 15 min it takes to change out.

 

My 97 Z didnt have 400 hp and the 58mm made a noticable difference between mine and my friends 94 Z, not very much by way of power but throttle response was F-in mind blowing in my Z. But yea it prolly isnt worth it as an early mod, maybe a step two kinda thing ya know?

 

it will help if u have the complete setup air intake too

 

i got the trickflow elbow and a k&n cold air intake...
