Q45 to Max ?

I think it would be pretty hard to do, since the Max is designed for a transverse engine and front wheel drive. Q45 is rear wheel drive. I would be really surprised if the Q45 engine would mate to the Max's transaxle.

Why think small? Here's what you really want:

"The new 5.6-liter 32-valve DOHC V8 will be placed first into the new full-size Nissan Pathfinder Armada sport utility vehicle. It will also be used in the Titan King Cab and Crew Cab full-size pick-ups.

Built on a new state-of-the-art line at the engine assembly plant, the design of the Endurance V8 features an aluminum block with cast iron liners, chain-driven dual overhead cams with silent single-stage timing chain, microfinished forged crank and camshafts, molybdenum-coated pistons and electronic throttle.

The engine will produce 305 horsepower @ 4,900 RPM, and 385 lb-ft of torque @ 3600 RPM."

Of course, the Maxima's tranny won't handle this any better than the Q45's V-8.
