E30 325i Rag-Top 2956 Report post Posted February 10, 2020 Any alternator for an M20Bxx engined model should bolt straight on to your engine. From experience there are a number of different sized ones that all fit, the 325i one was pretty big but I don’t know the electrical rating sorry. The M20 5-Series might be bigger still as they had more electrics in them. Check your wiring is in good Nick and should be ok to update. Quote Share this post Link to post Share on other sites
