I'm selling my 1990 Nissan 240SX Automatic with a KA24E, if it doesn't sell though, I think I'll keep it for the long haul, so I'll want to have the Motor Rebuilt... Where and How much would this cost total? Shop owners, feel more than welcome to post a quote/timeframe to me... If the car doesn't sell within the next 3-4 days, I'll be doing this to build it up for some basic modifications.
