D@mn you're lazy.

The RB25's transmission is slightly longer, and the output shaft slightly larger than the 240SX, so a new driveshaft is needed. If the Skyline's driveshaft yoke was included in your clip, slide it into the transmission and shove it all the way forward. Then bolt the stock driveshaft to the differential and let it hang. Measure the distance from the center of the U-joint on the diff to the center of the U-joint on the back of the transmission and--this part is important--subtract 1 inch to allow for driveline movement. Take all the pieces to a driveline shop and tell them "I want this yoke (Skyline) and this rear U-joint (240SX) on a one-piece driveshaft this long (your measurement)." Then give them money (probably a few hundred bucks). If you don't have the Skyline yoke, you can use one from a twin-turbo Z.

Can you handle that? Good luck. Not as hard as hard as you think.

actually you dont need to do any of that. get the motor mounts from mckinney motorsports and it fits everythign fine.

rb25jun · 10-06-2004, 06:18 PM

if all i need are the motor mounts why do they sell it with a drive shaft?? as a package.
