Ive heard theres a diffrence in the cams from a manual tranny and an auto. I recently just did an obd2 gsr jdm b18c swap into my gsr 99 integra. the motor I got was off a auto tranny. I think there is a diffrence with the cams cause you can barely tell when my car hits vtec. the motor feels very healthy and smooth. there is just close to no audible cross over to vtec. the car still pulls its just you cant hear that crossover. im throwing no codes. has anyone else had this?

 

bump... nobody knows?
