I'M NEW TO THE NISSAN GAME AND WAS WONDERING WHAT HAS TO BE DONE TO PUT A 91 AND UP MOTOR IN A 89-90 CAR.
I BOUGHT A 1990 240SX WITH A BLOWN MOTOR. I WANT TO GET IT RUNNING BEFORE I SWAP THE SR INTO IT.
I WANTED TO KNOW IF EVERYTHING WILL BOLT UP AND "PLUG" INTO MY CAR.
DOES THE WIRING NEED ANY CHANGES?
DOES THE 89-90 TRANNY FIT ON THE 91-UP BLOCKS?
AND SO ON.
IF ANYONE HAS GOOD KNOWLEDGE OF THIS PLEASE EMAIL ME SOME HELP.
THANKS FOR THE HELP,
SCOTT

Before posting next time, insure your CAPS LOCK key is OFF.
At the very least you will need a new gauge cluster, and PS lines. You will want to run all the wiring from the DOHC for a clean install.
The SOHC tranny will bolt up to the DOHC.

Yea basically what he said, its pretty straight forward.. the wires being the tricky part.....

The thing im not sure of tho...... but it would be common sense that you would need a DOHC ECU perhaps?
