Hey mate, all you really need to mount the engine is some Castlemain Rod Shop engine mounts. Cost about $150 i think, which is pretty good i reckon, no mucking around then, just drops straight in then. But you will need to make a crossmember for whatever gearbox you want to use. check out www.gmh-torana.com , there is a couple of people doing rb30-25 conversions on there.
