beemwr 46 Report post Posted May 3, 2020 1.Have an M50 engine, on the block l can read 31250976 and underneath these nos.20 6S 2. What cc engine wouldthis be? The sump is at the rear of the block suggesting it came out of an e36,I believe. 2. Hoping it is an M50B2.5TU and whether it would match up to a e46 manual gearbox and which wiring loom and ECU would best be used? Quote Share this post Link to post Share on other sites
beemwr 46 Report post Posted May 3, 2020 Been searching and pondering and tentative conclusion is that the 'code' 20 6s 2 is the best clue to suggest that the engine is from a 1993 e36 M50B20TU Right or wrong? Quote Share this post Link to post Share on other sites
