Ok, so kinda stupid question but I just wanted to see on here if anyone knew for certian. I know that there is a difference in the bolt pattern and valve cover design between S13 and S14 KA24DEs. My question to those of you who have worked on both motors is, are there any other bolt differences? Mainly I am concerned if the upper timing front cover is different between the engines as well if the lower timing cover is different. I'd assume that atleast the lower cover is the same as I'd assume they run the same blocks, but with the different head designs I was unsure if there is a difference in the upper front cover. Any help/pictures would be greatly appreciated. I did run a quick search both here and google, but only found references to the valve cover differences.
