im going to buy a jrsc for the time being. the jrsc is for a y8, the guy said it will work on a z6 crank pulley. i found a low 105k kms 88 crx motor locally so i thought id throw that in the car and bolt up the jrsc for now. so does anyone know if the crank pulley on the 88 si motor ( i think thats a a6 right?? not up to speed on my honda motors yet) is the same as the z6, or if i can swap the crank pulleys around?
