Cummins 4 B series, 3.9 L
4B = Simple air intake
4BT = Turbo
4BTA = Turbo and Aftercooler (either Water/Air cooled) or CAC Charge Air Cooled
Many different power ratings on all of the above engines. Power Rating strictly depends on the CPL # ( CPL = Control Parts List). The CPL # totally describes what parts make up the specific engine, power/torque, top RPM, Injector pump timing and Injectors, plus a lot more.
