I believe mckinney makes a kit, the stock mounts are pretty close to linign up with the crossmember, you can slot them and make it fit but the engine sits too far forward and too high, it wouldn't be too difficult to fab a new crossmember to olld the vg but the steering column might be a bit of an issue
as for trans, ideally you'll use a manual trans form a Z32, custom driveshaft
you'll need some sort of ecu, weither you sytay stock or full stand alone
here is a thread fomr hybrid with a vg30dett, same motor but wiht a couple of turbo's to get in the way
