i don't see how the AWD setup could work with out a ton of custom work, and not to mention having around $10k to blow. i personally think that money would be better spent swapping in the HLSD trans from the maxima. from there you can get cams, then PnP head, port match upper and lower intake manifolds along with throttle body, get a good tune and raise rev limit to 8.5k. you'll be beyond happy with that, and it would cost around the same amount as just swapping in an AWD trans. you could also get the speed force racing intake manifold with a 2k9 throttle body instead of porting the manifolds and tb. all this would put you WELL over 300whp.
