like the title says im trying to decide on one. i am going with powerjection 3 and will upgrade to 75 to 80lb injectors after i get a new bottom end, but for now im only planning on 6 to 8 psi pump gas.

have a few questions


1) do i need an intercooler? compression is right at 9.4:1 with vortec heads( yes i know... iron heads)

2) will a 38mm wastegate let that much air past for me to run the s475 that low?

this is set in stone, i ordered a walbro 255 and turbo xs bov. and will be ordering powerjection 3 next week, unless i find a good deal on a turbo first.

will i reach 550 or so with this low of boost and will it be pump gas friendly?
