The Incomplete, Complete Guide To The RB20 Engine

Welcome to the incomplete, complete guide to the RB20! Whether you think you know everything about RB20s or you are still convinced you should use yours as a boat anchor, you will learn something about RB20s from this site. I have created this site to compile all the information I can about RB20s in hopes to clarify every piece of misinformation and fill in the gaps for missing information.  No more looking at forum posts from 2006 with dead links or stressing out about ordering the correct parts. Everything will be explained in as much detail as possible on this site. There are many different versions of RB engines and some of the information may cross over, but this website focuses on the RB20DET.

Finding information about a 30+ year old engines sold half way across the world in a language I do not speak is very difficult, so please let me know if I have made a mistake or you have information you would like to contribute. *Full disclaimer, information has been gathered from my own personal experiences and trustworthy sources, but still may not be 100% accurate as there is still so much I do not know.* I have done my best to weed out misinformation and label things I am not 100% confident in. I have learned so much, but there is still so much to learn hence why this is the incomplete, complete guide.
