About my 240sx

[S-Dimensionz]

I have a 89 240sx I have an engine out of a 96 240sx I have a wire harness and ECU out of a 92 240sx DOHC. My question is can I put the engine into my 89 and is there anything else I need to get to make it work in my car.

Just the OB2 harness and you should fine IIRC.

no, you do not need an obd2 harness... use the 92 dohc harness you have some emissions sensors will not be used as s13s dont have it.... you need a s13 dohc distributor, the wiring on the dohc and sohc dash plugs are also different so you will need to rewire, you need an s13 lower engine harness to make life easier, if you want powersteering you need dohc lines...
