I have a b16a engine with the si computer and i was just wondering how i could get it to redline at 8000 instead of 7000

 

why would you wanna do that. im sure the b16 doesnt make power that high. but if you got cams, you could get a higher redline with valve springs and retainers. or you could get a chip, or a whole new ecu. but its really pointless without cams beucase there is a certain point in your power band where you stop making power adn you dont wwanna go too far past that

 

get a chipped ecu or vtec controller i think allows you to adjust it... not sure

 

if you have the B16A swap then Si (p28 ecu) will simply not cut it indeed. you can chip the ecu or get already chipped version or stock P30 variety.

check my sig for different options

 

vtec controller only allows you to fine tune your fuel and set vtec cross-over points, not make your rev higher.

 

yea sure, go ahead and raise you rev limit without upgrading anything else. then come back in here and post a question like "What is the ticking sound coming from my engine?"

 

The b16 makes its peak power at 7600rpm and was deemed by the factory to redline at 8000rpm. It will last turning 8000rpm for quite some time. He doesn't need to upgrade anything but the ecu.

 

My very humble opinion...
I feel that raising the redline on a stock engine is a little risky because the stock valve springs were only meant to go so fast before you get some valve float. Even if your car theoretically makes usable power above the stock redline doesn't mean that the stock engine will handle that rpm. Engine balancing, spring rates, and other things become questionable beyond the recomended redline. You're not going too far past the stock limit, so maybe it would be ok, but I'd wait until you hear back from several people who say they have done exactly that with no problems. Good luck.
