What is different between N20B20A and N20B20
Hello!
I just bought F10 528I and engine was replaced to N20B20B. I try to search for the information the original engine should be N20B20A. I need to get more understanding what the different between A&B? I.E. Cylinder, spare part, capacity of oil, HP power. Maintenance issue. Thank you for answer. |

You will see the different outputs on the N20 depending on model trim (Though you do not see B20A or B20B there if you look carefully) The Engines are for the 520i and 528i Series from what I researched. Compression Ratios are different as well with the 520i Series having a 11:1 and the 528i have a 10:1 This would go the same for all the various models of that had a 20i and a 28i that also used these variants as a reminder. Hope this Helps! Last edited by ChiltiCoatl89; 07-31-2023 at 04:43 AM.. Reason: More info! |
