How do I find engine model no for my BMW 318?

Help! My BMW needs a new engine as a piston apparently punched through the base of the engine. I've been looking around for a second-hand one but am getting confused by engine model nos. My car is a V reg (1999) 318i SE E36 saloon shape. I can't work out if my engine is M44 or M43 (or something else!). Also would a different engine model fit /work anyway?|||The engine is an M43 (based on the info supplied). Enter the last 7 digits of your VIN number on www.realoem.com and it will give the engine number of the car.





Any E36 engine will fit your car (even the M3 and M3 Evo's) but you will need to make a number of additional alterations, depending on the engine, including (but not limited to): -





Gearbox


Prop-shaft


Differential





There are three BMW magazines in the uk that advertise BMW specialists or have a directory in the back, Total BMW, Performance BMW and BMW Car. Give a few a call and see what they've done.





Thornley Motorsport and Bexley Motorworks are featured regularly, as is CA Automotive.





I hope this helps,
