whats the best choice to do with a 80mm TB? the 78mm or the 90mm LSX Intake?? the 78 is cheaper by like 200 bucks.. and i dont think i will get any extra power with the 90.. but i thought the 78mm would cause problems cuz of 80mm TB...

 

Id stick with the 78mm with your mods. The 90mm is more for big cube and H/C motors.

 

Go with the 78mm.
