’89-’98 240 SX U.S.A.

Your kit should include:

Instructions for in car installation.

1.        Depending on what is all ready on the engine, like a turbo or full header, in may be easier to put the vehicle on jack stands and get access from the bottom. You will need to hold up the motor while the stock brackets are removed.

2.      You may also need to remove the lower steel transmission braces from the block to the transmission and the brace bracket under the intake manifold to the block.

3.        Remove the two nuts from the top of motor mounts that go to the frame. Save these, they will be reused with the new mounts. You can also loosen the bottom nuts, this may help with installing the new brackets.

4.        Place a jack under the oil pan in such a way to lift the motor without denting the pan, lift the motor until it’s just off the mounts. It can still be on the studs, but without pressure.

5.        Remove the four bolts (Per bracket) that hold the stock steel brackets to the side of the engine block and remove the stock brackets

6.        Install the new lowering brackets with the stock four bolts. It’s a good idea to ease the motor down a bit to align the brackets prior to tightening the block bolts.

7.        With the block bolts tight and the engine sitting down, you can check the pan clearance to the cross member. Soft mounts may allow the engine to rock to much and contact the cross member. You can add a washer or two between the new bracket and the motor mount to raise the engine if required.

8.        With clearance checked, you can now put the nut back on the motor mount and tighten it down.

9.        It’s a good idea to check if the oil pan touches the cross member after the is driven to verify the mounts are not allowing the engine to move to much.

10.        After a test drive, if you feel excessive vibration from the driveline, you can lower the transmission tail shaft by adding washers between the trans mount and body. Be sure to maintain enough threads in the body to hold the transmission!!!
