6 months later still doesnt run right- sorry so long HELP!!!

[ShifDown96240SE]

I was posting a while back about swapping the S13 motor over to my S14, and everyone said that as long as my s14 intake mani was still being used it would work-WRONG. My head was ported too much for that to work, so I swapped over the port -matched intake mani from the s13, and it didnt run because of the harness and ecu didnt match. So I bought a harness and s13 ecu(which courtesy nissan in texas sent me a power harness instead of an engine harness, and when I sent it back they said it was burnt up and wouldnt return my money, they sent it back to me and the harness is in perfectly new condition like they sent to me in.....). So 700 bux after that, we get it all hooked up perfectly, but the car still doesnt seem to have that much power(seems less than stock), and it starts to struggle in gear at about 4Krpms, and it wont go past 5.6K!!! But for some reason it will rev up just fine all the way to and past redline(theres no more limiter, and it only revs out of gear all the way up most of the time). The engine seems to sound nice but it doesnt want to drive right. It still has the s14 crank sensor and the s14 transmission, and cams in the engine. PLEASE HELP ME!!!!!!!BryanSo Cal UTI Student

You have a s13 harness and ecu with s14 components?? Is there a engine light on??

did u run the ecu for codes?

[ShifDown96240SE]

S13 engine, s13 engine harness, s13 ecu, s14 body and chassis, no codes at all, fixed all codes, runs like hell. beautiful engine and setup, even the nox, and smog stuff is within range, not too lean or rich.
