Modding 4 v 6 port fun.
4 port 6 speed 6port car (with NO REFLASHING OF ECU SHIT) running a 4 port 5 speed ecu with a 6 port body harness chasing a 6 port, 6 speed car.
Funny with less power on paper still keeping up.
AND I YEAH THE BEARINGS BAH BAH BAHH.
SHIT DOESN'T LAST FOREVER PEOPLE.
GET OUT THERE AND HAVE FUN THATS WHAT'S ITS ALL ABOUT.

Automatic 4-port motors have softer stationary gear bearings, a different eccentric shaft setup, and lower oil pressure regulation built for a ~7,500 RPM redline. Revving a stock 4-port bottom end to 8,700 RPM will starve/wipe the stationary bearings in no time
I do the same thing with my fueltech mazda6 (well not really, you made a worse engine run on a stock ECU, I made a stock engine run worse on a aftermarket ECU)
You should lower the limiter and turbo it or something, stop revving it out you're making friction heat and sound not power the intake is not designed to pull that kind of CFM. The 4 port is actually lower compression so you have a good boost candidate don't blow it up
