My friend has a 1988 crx dx d15b7 1.5L engine that has bad rings and instead of replacing the rings we were wondering if we could change out his block for my 1992 Civic dx d15b2 1.5 L. The engine ran perfect when i pulled it and it only has 102k on it versus his 192k. would this be a direct change over for the blocks?? are the identical?? Im not sure if i have the engine codes in the right order with the cars, but you get what i'm talking about. Thanks for any info you can help me with.
