4bt

[Rotty]

Does anybody know which turbo is on the 4bt?

I am in the process of researching and would like to do some serious performance enhancement before I install the engine into my 53' GMC.

Also, which pump in used on the 4bt, is it the P7100? or VP44 type. I have seen information that maybe both types are used. But when I go to NWcummins.com I see on there picture a P7100? inline type.

Any information would be helpful.

Besides, I have learned more about diesels in ~9 months than working on them (chevy) many years ago as a grease monkey.

Thanks... .

Have you thought about a B5. 9? Guy down the street has a '46 Chevy COE with a Dodge/Cummins B in it. Ohhhh it's nice! Dual stacks, lotsa power, it does GO!
