What should a B16a engine redline at ?

 

8 grand i believe

 

what ECU are you using? Some people say 8200, some say 8k....

 

exactlly also depends if auto or m/t ECU autos have a lower rev limit.

 

from the factory is 8000

 

88 CRX Si ECU

 

for that crx ecu your vtec won't be working and I believe the rev limiter is 6500 rpm on that ecu

 

Well I know I got the vtec, it screams Not to mention the V-AFC shows it. 6500 for rev limiter? That's way too low

 

ok you have V-tec because your running a V-AFC to activate V-tec, the rev limit on a SI ecu is 6500 cold and 6800 warm, you dont have a B16 ECU if your rev limit is below 8k with no CEL, now if you have a CEL the rev limit would still be 7200 RPM's
