what year is the best for the 5.9 cr i am building a another fordcummins and am not too familiar with the cr

 

My vote goes to the '03-04 555. But I'm a little biased.

i am curious about what makes one year or modle better then others

but thanks for your vote

 

03-04 get awsome fuel ecomomy and can be modded pretty good

04.5-06 get way better horsepower numbers the computers are way bigger and you can play with them more

i have an 03 and love it

most kits i have looked at use 03cr engines

 

i have been looking for a 05 i also hear they make better power

 

yeah 05 make awsome power

i guess if you could find a wrecked 05 that would be easy just swap every thing over

hear is a web site might help but you probably have already looked at it

The '04.5 and newer (600 and 610) can make more power but also is a little more finicky with the injectors. Also a penalty with lower fuel economy.

thats what i plan on doing but i want a nv5600 trans
yes i have seen that site but and there are a couple more out there that are good too

 

A good old Fummins. I like my 04.5 but I think all the CR engines make good power. They all seem to have their own combination of power adders that they like.

 

that is true just pick your beast in the CR family and you will be happy

and there so easy to drive

got to love smooth power curve of the cr

 

You cant really go wrong with any CR. Now puttin the superior Cummins in the inferior Ford...I dont know about that!







J/k (only halfway); sorry I couldnt resist!

 

The 05's are supposedly the best flowing heads. Other than that I like my 03,, especially now that there is more stuff for our smaller computer,, lol,,

Are the '05 and '06 heads different?

 

couldn't agree more ... except that we have an '06 and love it ...

 

i like the way the 12v's sound and it seems like they can crank out the power too, plus less electronics to go wrong.
