You said exactly what i was thinking, only more eloquently.

BUMP for you. I'm sure cumminalong will know what the going rate is.

EGT being lost inside the crossover pipe won't help your engine any in the grand scheme. You want to get it out and away from your engine. In that regard, the larger pipe is better. However, you want to hold on to heat as it makes a big difference in spooling turbos. I have a 2.5" CO pipe and i...

3 inch pipe also has larger surface area. It's possible that this would cause you to lose some heat energy in the exhaust that would normally be exerted on the turbine wheel.

GM got rid of cast rockers because they would crack, and eventually, break in two. The stamped rockers are better IMHO. However, the plastic pins that hold them on the pivot shaft is pretty goofy

The forged crank is listed for 950 bucks. Scat cast steel cranks are quite a bit stronger that the factory cast iron. I'm not sure i would swing the extra 650 for forged unless i were trying to build the world's most powerful IDI GM diesel

My thoughts as well.

I just remembered that the LS series engines are all distributorless. There would be nothing on the end of the camshaft to drive the oil pump. The ls engines use a gerator style oil pump that's crank driven.

Well, the 6.2 definitely can turn some rpm. The stroke on these engines is relatively short for a diesel. Governor springs aren't the only thing limiting you. A rotary style IP is always limited in fuel volume at higher rpm. A p-pumped cummins can turn 5k, but the P-pumps have a plunger for...

Excellent point. I forgot the LSX engines shared the same firing order. Whats even cooler is that, according to all data, the LS series engines also have the same cam journal size as the 6.2/6.5. The 6.5 uses an undersized journal on the number 5 bearing that the lsx doesn't share but that could...

I can vouch for the torque converters being junk. Mine slips like crazy.

Nope, 6.2/6.5 cam journals are bigger than BBC cam journals. Just checked out of curiousity

Hooking up the oiling for the turbo is a non issue. The 6.5 used an electric fuel pump and had the turbo drain running to the old mechanical fuel pump port on the side of the block. Supplying the turbo is just a matter of putting a tee on the back drivers side of the block where the oil pressure...

Its worth the 300. So long as the 700r case wasn't damaged, anything else can be replaced. Is the transfer case coming with it?

I'm pretty sure you're right. Either way, its good to see someone tweaking the old db2 cause i'll never run an electronic IP on my stuff.
