Cummins 4BT vs Cummins QSB 4 cylinder

Bikerso · 12-12-07, 02:53 PM

I am researching a possible Cummins engine for old FJ45 and was wondering if anyone has had any experience with the newer Cummins QSB compared to the older 4BT engines? I am familiar with the Dodge Cummins engines when it comes to the 12 Valve Vs 24 Valve----I would much rather have the 12 Valve. I was just wondering if the older 4BT was still a better engine than the newer QSB? Thanks in advance for any help.
