This month I plan on buying ...a aluminum intake manifold, 75mm tb/plenum combo with a tb spacer, U/D pulleys and a CAI..Will I be able to notice a diff installing them all at once? Hmm about how much power would this give me..think I could hit a 13.4X with this + my current mods?

 

LT's, o/r mid pipe, Typhoon or HPS hardballer intake, accufab tb & plenum, Steeda UDP's. Def get your exhaust.

Plus look at getting Subframes connectors, and maybe getting some aftermarket upper & lower c/a's and a good set of DR's.
