under my hood im running a b16a with a 95 gsr tranny when i had my stock ex d16 motor and tranny i was able to hit 75 going at 3,000 rpms easy maybe a little more but now i have the swap and when i hit 75 going toward 80 im going at 4,000 or about 4200 ... i wanna know if this is bad for the engine if i go a long distance going 80 or 90 and the rpms are at 4,000 i know the tranny has shorter gear ratios for better acceleration but could the b16a handle it ?

That's normal. Your B16 spins more rpm's to generate it's power than the D16 does. Going 85mph in 5th gear on my B16A transmission puts me close to or around 4,500 rpm's. I also commute four hours a day total driving time doing that speed here in Atlanta. The B16 redlines at 8,000 rpm's. 4,000-5,000rpm's aren't going to hurt it.

ahh ok i thought it could justwanted to make sure thanks...
