Troywright68 Posted June 3, 2017 Share Posted June 3, 2017 Hi, I have a 2002 Rd Mack which has had the bigger injectors installed. Which turbo do I need to increase it to 400 hp?

MACKTRUCKS4 Posted June 3, 2017 Share Posted June 3, 2017 What did you start with? My 2000 Rd was a 400. I installed super flow injectors and changed to a 427 turbo. Running 490Hp.

Troywright68 Posted June 4, 2017 Author Share Posted June 4, 2017 I started with the 350 Quote Link to comment https://www.bigmacktrucks.com/topic/50055-which-turbo/#findComment-371399 Share on other sites More sharing options...
Mackpro Posted June 4, 2017 Share Posted June 4, 2017 With early 98 through 2002 ETECH engines , the only difference between 350 and 400was the program. However Mack wanted us to install a larger vibration damper if the engine had the smaller one on it. Being yours is a 2002 it could have either the ETECH or the CCRS style engine in it. I believe the CCRS engines were like the ETECH and the 350/400 used same everything but programming. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/50055-which-turbo/#findComment-371428 Share on other sites More sharing options...
Mackpro Posted June 5, 2017 Share Posted June 5, 2017 After looking at 2 different charts I have found on the CCRS engines, Some 350's and 400's used different turbo part #'s. However some used the same.
