I know the FJ that was intercooled had a water cooled turbo and these were smaller than the early turbo fj motors. The smaller version made 160rwkw on 14psi, so if it is the bigger verison that i would assume it should make more and could run lots of boost, no ceramics. So get it rebulit, $300 or so, and run it, it will be a little more laggy but not too bad.
