    So I have an 02 379 with a red top celect plus, holset 1919 turbo and upgraded fuel pump. I spun the number 2 and 5 main bearings and now I'm looking at used replacements. I don't know squat about cummins. I've been a cat guy my whole trucking career. I was told the only difference between an n14 plus (black top) and an n14 celect plus (red top) was the ecm. is this true? Can I swap out a celect plus for just a plus? Am I going to be pissed down the road that I did that? Any help or advice would be greatly appreciated!

    there has to be more different than that i know they run different injectors and cam also different ecm and the last thing that a lot of people forget is the cam follower gaskets are different as well. besides those the mechanical like pistons and head everything is same.

    Early n14's had problems with fretting at the main bearing saddle. Beginning with engine serial# 11875596 changes were made to improve durability. That was early 1998 so look for something newer than that. Being a red top doesn't mean it's good or bad. The first n14's in a 460hp rating were red tops. I'd look for any 525hp rating built after 1998. Check the engine serial#
