Which Turbo is best for track racing?
 

im currently building a trackcar and i am kind of indecicive about which turbo to use. The track im using it on is a short track so i need something that spools quick. Let me know if you guys have any experiences on the topic.

Have you looked at the Apexi RX-6?

"Isamu" RX6B turbo kits are the flagship series from A'PEXi. All Isamu kits incorporate the world acclaimed IHI RX6 turbine. These kits are all external wastegate style and come complete with all necessary hardware. Isamu turbo kits are also distinguished by the high precision exhaust manifold. These manifolds are beautifully TIG welded using SUS304 high grade stainless steel. The RX6 turbo is a high precision ball bearing turbo offering large horsepower gains without compromising the low end power band. A racing wastegate comes standard with the kit allowing for stable boost pressure. The kit comes with all necessary gaskets and hardware."

gt35r, or a 500r from aspec, jsut get ahold of them they will help you find the exact turbo (although they would probably steer you tword the one I mentioned).

Im using GT42.... roughly 600 RWHP soon.

We are talking about tracking the car not drag racing.
