What is the donor motor from and what is it going into?
donor motor is from a jzx90, but the waterpump pulley, ps pump, loom and ecu is from a jzz30 (thanks to a toymods member! forgotten his nickname)
it's going into a W201 mercedes. I did have a rb25det in it... but I had to compromise suspension/balance to fit it in. I had stupid reasoning to go for the rb25det and against the 1jz Oh well... I can transplant the rb25det into a r31 after I'm done. should be basically a drop-in transplant
