second gen throttle bodies can be bolted on this engine, and uncork the exhaust a bit for a free uptick in power--people complain that theres no factory support for hotrodding these engines, but they already have most of the upgrades from the factory--only in the last 3 years has nissan and ford stepped up to match the moosemotor in size, making their own 3,5's. a second gen motor is already hotrodded--just install it into a smaller vehicle to up the p/w ratio.
