"Holden 5 speed" As in the stock RB30ET or RB30E gearbox? Yes, All RB motors have the same rear gearbox bolt up patten. Even RB26s.

The MF5 box doesn't even hold up to the RB30E half the times LOL. You could use an RB20DET box which are usually around $350-450 second hand which would be a better idea. I'll be doing an RB20 swap as soon as mine gives way. Good, cheap upgrade I say.
