tune 0 Report post Posted March 31, 2008 Hi all, I've got a 85 323i 5speed just wondering if i put a AFM off a 2.7L or 2.5L on the 2.3L would it make any difference performance wise? My brother has a skyline with an rb20det and he put a nissan 300zx AFM on it and it went hard. Quote Share this post Link to post Share on other sites
OLLIE 26 Report post Posted March 31, 2008 um i don't think it's a good idea. The AFM is designed for that particular engine - you are better spending your time getting it tuned properly you will see a better result performance and economy wise. Even if you just tune the Air/Fuel at idle. in saying that - are the AFM's any different between those 3 models anyway?? Quote Share this post Link to post Share on other sites

My brother has a skyline with an rb20det and he put a nissan 300zx AFM on it and it went hard. Its not as simple as just plugging in a bigger AFM. Ask your brother. He is ether running an aftermarket ECU like a Power FC or Link or has had his ECU chipped to suite. You would need to do the same on the BMW's. As Ollie said. Just get her well tuned.

Justlikemusic 0 Report post Posted April 9, 2008 M30 AFM is a common swap on M20's... big difference in size. Google M30 AFM E30 or something.... heaps of info. I think you can use any AFM with the last digits 021 or 020 or something like that. Research it through google. Quote Share this post Link to post Share on other sites
