If your looking at a new turbo with a price tag over $1k your looking at ones that either way to big for your car, or are marked up. Also with the JWT ecu's you need the cobra MAF, their wiring harness and a bunch of other stuff for it to work properly, ontop of that the tune will still not be very good. just get a nice rebuilt holset, buy everything to run megasquirt, buy everything else you need, tune it for 14psi, then tune it for 9psi and be happy.
