S13 Motor To S14 Motor

[X 350GT X]

Hey Everyone,

My S13 Motor was blown. Someone is selling a 98 S14 Motor. Can I just drop this in my S13? What do I need to change? ECU? Whatelse? I searched but couldn't find anything.

Thanks

What you will do is use all the s13 electronics. Just change out the manifolds and the dizzy and you should bet set. You might as well change out the front and rear main seals, water pump, thermostate, tensioners, chains, etc while your engine is out. I would also use the s14 upper intake manifold and the s13 cams on the new motor.

And you WILL be set. Thats all you need. Just remember that when you order engine parts its for a '98 240SX. Valve covers and stuff are different between S13 and S14.

you could drop in the 98 KA with the ecu and engine harness with no problem other than splicing about four wires on the engine harness to the s13's body harness. You'd also need to splice wires to the tach, speedo, and temp gauge.
