Yeah the box R likes 90mm throttle bodys im building my dart block with that intake cause im gunna run 700rwhp+ but im not gunna go with a 90mm im going with 80mm the intake will lose about 5 more hp cause the intake is made for 90mm as said in MM&FF but im building the engine all together so im not going to be running that intake without a S/C or turbo of some kind.

yep, no emissions on my car, what is the advantage to the 80?

dude car won't run right with a 90mm unless you are pushing out tons of power...like everyone said 90mm is huge...that's which basically no one on the street runs bigger then a 75mm
