Hello guys, I am currently in the middle of a jdm d15b swap on my brothers 91 ef sedan. I want to keep the power steering but however the jdm d15b crank pulley doesn't have the v style pulley for the ef ps pump. I tried swapping over ps pump pulleys and the jdm d15 pulley has a bigger bore for the bolt so I would have free play on the d15b2 ps pump. I managed to fit the ef ps pump by doing some cutting. so the only thing left to attempt is to swap the d15b2 crank pulley to the jdm d15b. I heard that it will be ok as long as it doesn't go from a 1.5 L to a 1.6 L due to the fact that the crank pulleys on a 1.6L work as a harmonic balancer. is this correct? any more input on this will be appreciated thanks in advanced!
