The MTQ kits are the best of both, they are Water cooled and Oil cooled Bonus! and a reliable Turbo system that is playing safe while getting good performance.my vote is a water cooled DTS kit. go see MTQ.
I've got 2 of them. one is running stock boost and the other is at 20 psi with cooler and some turbo mods.
A GT2860RS with a 0.64 rear should be fine to then, much higher and personally Id be moving to a .86 rear.thanks benno, really helps!
well for the initial set-up will be running about 8-10psi until i am comfortable and then i will up it to 15psi down the track when i get an intercooler.
