No i dont see it "manifesting" either, I did a little research just to see some people say "its a super hard swap" but how? past some wiring, custom mounting and custom shaft, wtf is so hard about it? It seems like a great swap to me, the picture above clearly shows the end product looking 10 times easier to work on. This car obviously wouldn't be a handling queen, i would never build a fagtastic "drift car" so scratch that idea, I think as far as cruising, some highway fun and a little 1/4 mile, this car would be the tits.

RB's look to have a median price of $1700/2200 for the 5spd. not really pricey.
RB25
Motor/tranny mounting
driveshaft
wiring, im sure taylor could pull this off, there no way I'd ever attempt this shit.

profit.

but seriously, it cant be that hard. Decent single setup, supporting mods = WIN.
