yeah, i've been told that the difference between turbo and na inlet manifolds is negligible... neither is particularly great for flow, but if it's boosted it's less of a problem than for NA anyway...
we didn't get the turbo 280zx...which sucks, and everyone i've inquired about in the US quotes ridiculous shipping charges...
i might try new zealand...they have more l20et's right? shipping shouldn't be too bad...might even be able to get an LD28 crank while i'm at it and built my L28 out to 3.1 litres...and turbo to boot!
another idea for the inlet manifold i've been thinking about is this set up

it's a EFI intake, cut at the start of the runner, to preserve the injector mounts, then welded to the larger twin SU manifold, with dual throttle bodies where the carbs were.... of course you have to port the EFI flange to match up with the carb manifold.....what do you guys think?
by the way, thanks for all the quick responses guys!
