Default 70mm or 75mm T/B?

Hello All,

I have a 02 GT that I am just beginning to mod. So far I have the exhaust done as you can see below, and I have my Densecharger w/ MAM and underdrive pullies on the way. Now I am trying to decide which T/B and plenum to go with. I know that I will probably go with Accufab, but what size is enough or what’s to big. I found a site where both sizes (70 & 75) are the same price so cost isn’t an issue. Thanks in advance for your input.

I have almost the exact same setup, and yes Accufab is the best brand to get. The 70mm throttle body is the best for you, until you get a supercharger. Then if you really wanna, you can get the 75mm.

70mm, a 75 will kill velocity unless you have a supercharger or turbo
