I got mine from Crimmo, its the one he used to have in his gold MR30 sedan! Beleive he got it from autobarn. Im only running 8psi atm (leaning out about 6k still on standard ecu and injectors, had it all ready to go but a house got in the way of things haha), it makes 162kw on jaustech's dyno...Crimmo used to run 14psi through it in his old car, never had a problem with the cooler getting hot, or heatsoak or anything.
What turbo you have on there?? Still the VG30?? What boost you pushing through it now??? Wouldn't be pushing that much more then 14psi if its still on there...
Oh and yes, another vote 1 for leroy, he does good work
