Hi, so my friend has a 1988 318i, which is running with an m40 on automatic transmission which he is currently working on. Its done about 160xxx k's, M-Tech body kit as well. This will be my first car and I am a huge fan of the e30 chassis. I am not the biggest fan of driving an automatic, and I am interested in converting it to manual. From my understanding a getrag 240 is what is needed for the conversion, but is it worth converting it? The m40 isn't the fastest engine, and over time I would like to swap the engine into an m50b25. Would i still be able to use the getrag 240 or will I need another gear box completely for an m42 conversion? I wouldn't want to waste money converting and then needing to get ANOTHER gear box if I decided to swap the engine. Any advice would be nice as I am new to this.
Cheers bros!
