There is an discussion in this thread from this forum. All I could really find in the time I spent. I couldn't find anything engine manual wise that was in English for officical documtation but I have seen the two, they are different also in combustion chamber size to match the bore. The reason why the sr18 that I saw wasn't used and was re-sold. This was at least 7 years ago but I think the port size may have been smaller also, but can not say so for sure.
