Hi Matt,
Thanks.. I get a smile every time I drive it.. I can tell you one thing... the 1kz-te gearbox is much larger than the 3L box, and I'd be surprised if it was possible..
My only complaint about the whole setup is that the standard diffs for the LN106 are geared to low for the 1kz. But if you have decent size tires you'll be ok.
Things you must have for this conversion are..the complete wiring loom with computer, steering column controls/stalk, dashboard with rpm speed etc, speedo cable, gearbox and one piece tailshaft, 1kz air box, (3L box is very small and restrictive) exhaust system upsize.
