S13 KA24DE-T into 98 S14 - Basic questions - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Did some searching with poor results. Anyone done this?

What's the best way to accomplish the wiring? I'm thinking re-use the S14 engine harness, modify it to work with the s13 motorset, swap the distributor over.

Does the Nistune type-4 board work with the OBD2 s14 KA24DE ecu?

What else should I be aware of swapping the 13 KA into the 14?

Use S13 KA wiring harness and ecu...done

I just did the opposite on my car

Thanks for the reply! From what I understand the s13 harness will not interface with the fuse/relay block nor any of the dash/interior connectors? Well without a lot of splicing, which I don't mind but would prefer to avoid if possible. Did you run into any other random issues with your swap?

Also I believe the 14 engine harness will work properly, provided I swap the 14 distributor and intake manifold over. I'd prefer to run the 14 ecu + harness, along with a Nistune board if possible..

If someone who's done this swap could confirm or post up other things I've missed I'd greatly appreciate!

If you have an s14 harness use that all you have to do is get a s14 dizzy and most plugs should line up ex. IACV and TPS etc etc and wiring a s13 harness into a s14 is possible and has been done but its a mess!!

eesforteen, thank you for the info. Sounds like s14 eng harness + s14 distributor + s14 I/M + s14 ECU is the way to roll with the s13 motorset.

My latest diggings on NISTune seem to show it only supports up to 1995/OBD1 S14 KA24DE ecus. I have a greddy e-manage that I can use but would rather not.. any input on EMS would be appreciated.
