Ok I just got one question. Any reason you boast about having a 91 engine in your 93? Was just reading the other thread about tranny fluids and "then again i have a 91sr20 in mine". Cause the engine from the 91 to 93 never changed. Maybe LATE LATE 93's might have the low port, and ever so slightly milder cams but 93's have the same engine as 91, 92's. EXACTLY.
