If you want more technology then what about a V8 from a wrecked Comonhore?
Getting something post VR shouldn't cost to much, and might be cheaper than an imported RB20det (which is not going to make as much power with out some more $$ spent on it).
Would be just as much work in terms of wiring, but there are plenty of kits out there that makes sorting things like the mounts, tailshaft and gear box out much much easier, which in the end will save $$ and time as these are the annoying things that will end up costing the most if you try and put an RB into it.
And tell me, honestly, would you rather have a 165kw 6cyl, or a 185kw V8 which never has to worry about Turbo lag
