hi, i'm a newbie to Nissan. I have a quick question. what's the difference between the red top SR20DETs and the black top ones?

Doba's240

difference is i have a blacktop and i dont have a redtop

J/K your best bet is to search, you'll find this answer right away..
blacktop is newer 94-98
redtop is older
im not sure if there are any power differences, ive read many different articles saying yes and no..so i dont know.
