ISR Performance RB with RB20 Transmission Swap Mounts for Nissan 240sx S13/14

The ISR Performance RB swap mounts with RB20 transmission mount are a complete mount solution for installing an RB20DET, RB25DET or RB26DETT into a Nissan 240SX S13 or S14 using the RB20 five speed. Engine mounts and transmission crossmember are designed as a set so the engine sits where it should for driveshaft alignment and steering clearance, and because the same kit works in both S-chassis generations, you can move the swap from one car to another if needed.

Bushing Choice

ISR uses a urethane engine mount bushing with a rubber transmission mount bushing. The combination dampens engine vibration without being overly stiff, which suits a daily driven street car as well as a track car.
