I'm swaping a crx si motor into my dx crx, and the dx has a larger crank pulley bolt. I have a bolt that will work for the smaller si pulley snout, BUT....The crank pulley's hub that I bought for the motor is much larger then the crank snout is. Are there different sized crank snouts for 88-91 crx si motors? I read somewhere there are 22mm and 24mm ones. Where can i get the right sized crank pulley, because mine seems to be small. Does this mean the crank is also smaller?
