KA24DE in 90 S13 with KA24E

ok so im going to buy a 95 KA24DE, this is what comes with the engine: tranny, S14 ecu, stock MAF, SR20DET injectors no wirining harness … now what would i need to do to make this thing work, ive been doing some research on KA-T and it pretty much says that i would have to get my ecu tuned for the s13 or get a piggyback EMS which btw im not understanding that concept all too well. Im thinking is going to be ems hooked up to the ecu so that i (hahaha) or a proffesional can tune it any input would be a appreciated and if this something thats been covered 10000000000 times sorry im a nOOb

I believe you also need to swap in a 91+ gauge cluster. Can someone confirm this?

yes you do. …

Get a S13 KADE harness and all the sensors so u can run a ODB1 ECU…Its easier to get it tuned vs the S14 ecu.

Ok sweet does anyone know of someone that has a wiring harness for the DE here and a 91+ cluster.

You’ll also need to get a 91+ power steering reservoir and modify the lines.
