I am new to the diesel performance and would like any info on how you guys would build this motor to tow with but still take it to the track and rock (50-60K a year). The block is an 01 that needs a sleeve. Sleeve it or buy an LBZ block? Rods? Crank? Cam? Head porting? Pistons? Twins or single turbo(Lowest EGT's for towing). I'm planning on a single CP3, EFI live, tranfer brace.Tranns will be built but not sure by who yet, all front end braces, and all the other basic bolt ons. I'm sure this one will be itresting since everyone has an opinion. All info is greatful.

Dont sleeve the block.

define "rock" while at the track.

If your only going single CP3, your looking high 11's on a good day in a light truck with ideal conditions.

Single pump will also dictate how much fuel you can push, dictating the charger size, dictating the heads/cam combo.

The truck is a single cab longbed. The only reason for a sinlge CP3 is the drag of the other CP3 for milage, unless I'm wrong a duelfueler is good. Mid 11's is just fine to keep it reliable.

Congrats also. After Dmaxallitech said not to sleeve it I guess I will have to find a short block LBZ or lmm.

I don't know Erics reasoning but I have a friend that tried running a sleeved 6.5 and it would pusn a head gasket out far too often.
