Both sites have some great deals, and i've heard great things about RIP. I'm looking to make a purchase soon, stock turbo can't handle more then 35 psi, its nothing to build 37 psi with it but after 35 its pure heat and egt's go through the roof, this is why i was leaning more towards the 14 or 16 cm housing, i know they won't light up as quick as the 12 cm but i'm worried about keeping her cool. I see where the turbo Dcreed mentioned would do me well, but i may not put compounds in it, I tend to look at 2 as one more thing going wrong, i know they've come a long ways in the past years but i'm still skeptic about them.
