RB25 with RB20 transmission... what driveshaft???

[NismoJunky]

I just put a RB25 in my s13 hatchback. I got a good deal on it because is has a RB20 transmission, I was under the impression that I could use my stock drive shaft like the RB20 guys, but I tried to put it in, and its too long.

are there any guys on here running the same set up as me? if so what did you do about a drive shaft?

Why not get a custom one made?

you can use the same s13 driveshaft. just remove or trim off a little bit of the gold dust cover at the tail of the transmission.

what kind of mounts did you use? i believe the stock driveshaft only work with the skyline crossmember...

I used some mckinney copy cat mounts from eBay

try using a different stock driveshaft. I forget which one is shorter... non s14 abs, or with abs.
