it will bolt in using the R33 crossmember and fit well enough to get you on the road, but the engine will sit a little higher and a little farther forward than is ideal. Some of the hood bracing will have to be removed to clear the throttle body and blow-off valve flange and the shifter will sit about an inch and a half forward of the center of the shifter hole in the floor. The Skyline's transmission crossmember is nearly identical to the one on the 240SX, but the transmission is longer, so it won't line up with the holes in the car. Again, you have options.

If this is just a show car, file the bolt holes on the transmission mount so it can slide forward on the transmission a half inch or so. Then shove on the flimsy, flexy transmission mount until the center hole on each side of the crossmember (originally a drain hole, not a bolt hole, but it will work) lines up with the rearmost mounting hole on the car. Bolt it on with one bolt on each side (it's supposed to have two) and go polish something. Oh, sure, the top of the transmission will be jammed up into the top of the tunnel, but that won't really matter on a show car.

Now, if you actually intend to use that big turbo six to make power, two bolts aren't enough, and having the transmission hitting the tunnel won't do.
Finally, if you want the engine to sit low enough to clear the hood bracing, the shifter to sit where it used to, the steering shaft not to hit the downpipe and everything to bolt in properly, there's a third option. McKinney Motorsports in San Diego, Calif., unStable Hybrids in Conyers, Ga.,Syko Performance in Torrance Calif, all make engine mount kits that move the engine down and back about an inch and a half. In addition to making everything fit better, moving the drivetrain, which weighs about 650 pounds, shifts the center of gravity in exactly the right direction. This is also the ideal option if you have an engine, transmission, harness and ECU, but no front clip.
