i've found alot of different opinions on throttle bodys and manifolds. if i am to swap out a diamante or gts intake manifold, do i need to swap out the upper, lower, or both manifolds? i've also heard of a guy that custom builds stock manifolds into short manifolds; any info on that? another thing, what is the best way to upgrade throttle bodies? i've heard of getting the stock one bored out (proflow, i think) that makes them. any info? also, is the stock throttle body off a gts or diamante larger than mine (01 gt spyder)?
