Ive got a 97 ka wired into my s13. Im using full s14 harness and everything. Its on a obdI ecu so that i can tune in the future when boosted. The first problem was if you gave it anything past 30% throttle it would start sputtering and try to die out untill brought back down. As i was driving home it got worse to the point of around 10% throttle.

Timing is dead on

It has fuel pressure

Decent spark

Im thinking the coil in the dizzy or maf..

any ideas?

This motor ran amazing when it was in a s13 running with s13 shit. Might as well just swap back. The reason its running s14 stuff now is a long story.
