the wiring is no where near plug and play. in fact, its pretty f-ing weird. i can do it though. the RB25 in that car will make it VERY nose heavy so be careful. you dont need to use the mckinney driveshaft, it'd be cheaper to just have one made. in fact, depending on which tranny you get (depending on your goals) you may even be able to use your stock driveshaft! there are two variants to the RB tranny. one uses an SR-style trans, while the other is MUCH larger. the larger of the two will use a combination of Z32 and S13 driveshaft parts making it a one peice driveshaft.

its most definately possible and the 02 housing needs to be modified to clear the steering rack, which we can also do for you.
