With support from my wife, I purchased a 87 528e MT with a blown engine located about two hours away in Long Island. From what the owner claims, he has a extensive service history and had many parts recently replaced. Also, the car was repainted last year. Same color combo as my e28. The owner said that a connecting rod broke in the engine. I was wondering if I could put in Botond's M20 engine that he has for sale from his 87 325e MT into this 528e. I am pretty sure some cooling parts will be different, but if the owner has records of recent coolant parts, I could just reuse those. Any thoughts?
