A few of my friends have mentioned this engine but I’m a little ignorant about them. How versatile are they? What are the pros and cons vs the 4bt?Not a Cummins but I've had a complete Isuzu NPR truck with a good running 4bd1t listed on here for 4 months at $3500 OBO and have yet to get a response.
Thanks for the info. It doesn’t sound like I’m gonna be interested in this motor. I’m not one of those guys that has to have EVERYTHING built to a ridiculous standard. But I do like ease,convenience, and simplicity very muchThe Isuzu engine is a good engine but does have some issues vs the Cummins. There are tons of aftermarket parts for a 4bt but not so much for a 4bd1t. Both engines have similar power in stock form and the Isuzu probably has a wider torque curve in its power. Transmission adapters often become an issue with the Isuzu. Companies who have made some have come and gone over the years. Not sure what is currently available. The Isuzu has its oil pump located in the pan and if there is interference between the pan and front axle there's not a lot that can be done. The Isuzu the Bosch A injection pump. Not a bad pump but not a lot of performance mods out there. Same style pump was used on 4bt industrial engines. The Isuzu has replaceable sleeves which can be considered a positive. Instead of boring the block, you just replace the sleeves and stay standard bore. Both engines are direct injection but later model Isuzu 4bd2t was indirect.There's a section on the forum dedicated to those engines so you can do some reading.
