Yeah, this question comes up once or twice a year. There are always a few out there who say it can be done, and yeah it can, but it isn't a simple pull your motor, swap it in. Like has been said we have a tiny engine bay, just imagine adding 2 more cams, 2 turbos and about 10-15 feet of 3"tubing in there. If you are going to go through the trouble and want to keep it Nissan, look into the VH45DE. It's a V-8, but the stock traynny on it will bolt right up to our TX-10A T-case. Also, it is lighter than a VG motor.
