I know this is an extremely old topic but I have been searching the site for the difference between the rb20det vs. rb20de. I have 3 rb20 motors 2 det and 1 de and would like to use the DE as a spare motor to build incase anything happens to the others.
So far the differences I have read are the DE block doesn't have oil squirters, possibly no spot for oil drain?
Anyone shed some light on this topic I'm sure has been beaten to death.
