MOST '93 B13's had the highport. but there were a few at the end of the production line that had the lowport. I know because I had one..
SR Engine Series
I have seen other references to this besides the one listed. It's just that there weren't that many of them, they call the lowport '93 models the "1993.5".
but really it should be more like a 1993.8 LoL
oh here's another reference to it:
93 lowport black on black testing waters NYC - SR20 Forum
I wish i could find the pic of my engine bay... from the one I wrecked in 2005...
here's another where Serban starts out stating that only the 1994 got the lowport and then some other guys chime in with actual dates of production and how the parts people ask if his 1993 is a low or high port..
sorry, hi-lo port question again - SR20 Forum

glad you figured it out. Make sure you grab a new crank seal while you are at it and if you didn't know DO NOT pop the pulley off using the threaded holes. That is unless you want to break your timing cover.
