Hi tr i got a question i got a 91 ka24de on a 1990 s13 chassi the car had before a 98 ka24de with the 98 wire harness and ecu etc.so now i got the 91 ka24de with the 98 ka24de wire harness ecu etc.and my car is acting up like its starts sputtering at high rpm's the car was off timing before and i got on timing and now its sputtering at high rpm's i was wondering if having a 98 ka24de ecu wiring harness etc on the 91 ka24de engine would affect the performance of my car.

 

you need an S14 intake manifold, and S14 dizzy on that engine to run it in your chassis if you're using S14 wiring harness and ecu.

 

do u know anybody that would trade my s14 wiring harness and ecu for an s13 one?
