i just bought a 91 crx si.. it has a b16 swap everything is clean..might try to post pics.. but wonderin i got in on it and my car shut off at 115 or so redlines at 8200 rpm lsd y1 tranny...pw0 ecu.. hassport motor mounts.. also i get a lot of vibration..anybdy know why it tops out at 115 the guy i bought it from said its the gears..not sure

 

the hasports will give you more vibrations....as for the speed limiter, idk ecu?

 

the limiter is a fuel cut in the ecu if you get it chipped or get some sort of tunable ecu a shop with a dyno should be able to remove that for you
