ISR Performance LS Swap Mounts for Nissan 240sx S13/14

ISR Performance's LS swap mounts for the Nissan 240SX fit every RWD LSx based engine into both the S13 and S14 with one part number. The trick is a small base mount pedestal paired with a separate mount bracket, which lets each mount pivot to account for the slightly different width and pitch between the S13 and S14 subframes. Other kits force you to pick a chassis, or compromise fit in one of them; these fit both correctly.

Key Features

• Fits all RWD LSx based engines (LS1, LS2, LS3, LS6, truck variants and similar)
• Pivoting pedestal and bracket design accommodates S13 and S14 subframe differences
• Urethane engine and transmission mount bushings that dampen vibration without being overly stiff
• Appropriate for daily driven cars as well as track cars
• Transferable between chassis if you move the swap to another car

Fitment

Nissan 240SX S13 and S14 chassis. On the chassis side bracket, the lower mount holes are for the S13 and the higher mount hole is for the S14.

Install Notes

Keep the two bolt lengths separate: the longer pair is for the mount to chassis connection and the eight shorter bolts go into the block. Set the engine, snug everything, check hood, steering shaft and oil pan clearance, then torque. The pivoting mounts make it easy to fine tune engine angle before final tightening.
