I talked To Greg Vogel 2 days ago about this swap. It would be a bolt-on for my P11. He can get SR style bellhousing for this tranny for around $300 or so + 8 week wait from Japan. The cool thing about this is there are many of these tranny's sitting in junkyards.
The next problem is the flywheel, its 225mm. I checked on maxima.org and maxima flywheels have 124 teeth or so. I don't know if this will be a problem for our starters or not. I imagine the the altima FW probably has just as many teeth.
