lol.. its not possible for people to know about this back in 1991...
seeing as how the S13 blacktop sr didnt come out till what.. 96? something like that.
but yes.
to the original poster.
get the third version of the redtop instead, it is the best one. came with 275hp and 300ft/lb of torque stock and was endurance tested at the nissan factory and it was able to maintain a steady 8000rpm for 10 hours straight without any catastrophic failure.
it is marked by cooling fins that are slightly slanted to the right on the head of the motor, and a red valve cover that has a slight tinge of orange in it
hope this helps
