As far as the actual engine, I've run into the issue of the DBW stock setup and the V8/V9s using DBC. I've read that using a 06-07 WRX or 04-07 STi manifold would work; but does this mean I need to swap over my TGV's too(or would I need the intake manifold's original TGV; assuming different bolt pattern), and would the original LGT TBW throttle body bolt to the WRX or STi manifold? Also, would I just be reusing my old engine harness(main thing is if I were to do top-feed conversion, they would still fit)?

Sorry for so many questions; I've been searching for basically a week now and couldn't find the exact answers I was looking for.

Thanks, Kevin

free bump, i also want to know
