Hi I'm Bryan Plummer new to the diesel world I have a ? My son is putting a 66 mm chrome turbo on his 2003 Cummings 2500 with smarty tuner double disk clutch. What other mods need to be put on

 

Bryan welcome to diesel bombers.

 

He is going to want a set of injectors with the size of the turbo he is using.

 

Welcome, there is a ton of knowledge here on the forum.

 

What does he have for gauges? If none I would say gauges next. Especially an egt gauge. When you increase fueling, you increase egt's.
And welcome to the site.

 

Thanks to all who have giving great info it's helped a lot. I have another ? I have a 2001 2500 24 valve Cummings the # 3 injector line has broken in half 5 times in the last 6 months. What could b causeing this to happen. It's pretty much stock just has pilled gauges , edge tuner, 4 inch exhaust.

 

Are all the original clamp blocks still in place and in good shape? Is there any bending preload on the line when you hook it up?

 

All clamp blocker r n place I take God care not2 put any stress on them when installing them
