ps. wat size turbos r u planning?
No worries, not picking on street cars just noting we're working from a completely different league: Rally. Isuzus have a lot of background with TMIC and if you look at the overseas IC turbo-diesel models they all have TMIC. You get much more surface area, simpler mounting options and greater plumbing flexibility. Heatsoak just isn't even an issue, let alone a concern. With proper radiant shielding on the exhaust components why would you?

As for turbo size we've been eyeing the T20, T22 and T25 range.

MoonRaker: I've been through the ringer with water/air IC's with my XR4Ti/Cosworth hobby. Too heavy, too complex, too inefficient. In some applications they work fine, but the general tradeoffs just aren't anywhere near worth it. In a rally application a water/air IC would likely self-destruct.
