hear are some pics of my old rotor housings.
The engine had done 48k from the factory and was running perfectly. I striped it down because I bought a new street ported 13b to go in freash for this year and I didnt want my original engine to go bang this cumming summer and leaving me off the road.
I have had a close look at them and i think they are in good condition but I am no rotory expert.
How much are they worth?
Well if they have not got hot (you can tell this by the Colour of the bottom of them), The Chrome is not flaking anywhere and there is no grooves they usaly go for about £100 each second hand.
Also check for hairline cracking around the spark plug holes
