Not trying to tell you what to do, but i think it would possibly be just as cheap to get one of those used motors from Japan. It would be a heck of a lot easier than trying to rebuild it. Not to mention, if you did rebuild it, there's always a possibility that you will not do somethin right, causing you to have to remove the motor from the car again. You would be very irritated if that happened. I know this first hand. My 91 Yamaha FZR 600 motorcycle tranny messed up. I took the motor out, fixed it, and came to find out if forgot to put a damn clip back on the tranny thing. I eventually just bought a used motor for it after i did get it fixed and screwed it up again.
