1G fits easy as pie, the ony things needed are custom gearbox and crossmember mounts and a custom sump, you just need a rear bolw sump, cut it off just below the pan rail, and turn it around, then weld back on. Radiator fits with the fan on the front, and there is still enough room for a 70mm thick cooler between there and the grill, albeit a little tight. I have this in my KE70 wagon and it is a very snug fit indeed, although a pain in the ass to get in and out without srcatching my very nicely painted engine bay
