There honestly isn't too much difference between the s13 red and s13 blk top SR20DETs. The main difference between the 2 are simply the year difference between the 2 colors. The associated ECUs do carry some differences between the s13 red and blks. With the newer type X black top. there are some difference between the normal s13 red and blks. Search around for some links on the main difference, I have them saved somewhere, if I find them, I will put them up.
