im building towards a turbo kit im going to blow up my new motor and build my old block with weisco pistons. i guess i can order them when i figure it all out. right now im working on the exhaust manifolds and figureing out the pluming issues. that motor bay is really tight. but yeah i think i need to upgrade to a bigger sensor. i have a friend who figures out all kind of crap formulas for different things and he tells me 2.5 inches before my runners will give my intake cfm charge .15 to .4 mach so around 2.5 will give me that. but i need a better sensor. 200 bux is a bit high. anyone have a extra one. my car is being used as a test bed for this company that makes turbo kits and stuff so well see how this works out. by the way... im thinking my secondaries are gonna be a pain in the ass with a stand alnoe.......grrrr. why didnt i buy another rice burner. was it the body kit. the bad ass headlights. or maybe the fact i beat the crap out of a si when i test drove the svt. i dunno. and yeah i swapped for another svt engine.
