Red cherokee: I tried to track down this engine for you ( I don't know where your gettin it from) My suppliers tell me its hard to get and that it will fail emmissions testing in Quebec.
As far as cons on the RB26 swap they are above.
I'm telling you guy your gonna have a run for your money, I'm usually optimistic about swaps but there are a lot of incompatibilities. Your going to need a diffy, engine ,tranny, ecu, clutch, mounts, 24 beer...The other prob will be replacement parts afterwards.
I dunno man I'm good with Jap cars but this really seems like an expensive project 10000$ plus
