Someone mentioned this conversion on one of the Facebook forums today, pretty much its a light truck motor out of a Nissan 1.5 - 2ton truck. Very similar to a ZD30 but it must have a longer stroke and heavier internals. It revs out to about 3000rpm. Due to its robust construction it can handle A LOT of boost. Some examples has reached 40psi. If anyone has anymore info post it up, I find this an interesting conversion.
