Hey, I just joined the F-150 diesel forum because I bought a Land Rover (LR) with the TDV6 and ZF8speed. While I understand the engines are very similar, there are a few major components that are not. Most importantly is the forged steel crankshaft added to the F-150. I also have been told that the connecting rod are also stronger on the F-150.



Does anyone know if the F-150 short block parts are interchangeable with the LR TDV6 to make it stronger, before I start tuning this truck? LR has Crank shaft issues, mostly in remote parts of the world. It probably has to do more with oil and maintenance, but who really knows. Forged cranks and rods are always better then not especially if your putting more power to a block that already says no.

As someone who does not own that motor,(Ram Ecodiesel) I think you should forget about tearing your motor apart, but rather think about how you can make your motor last and give great service and performance. As far as tuning, I would think about tuning for more efficient operation, rather than maximum hp/tq. For example, eliminating EGR will probably add longevity, and eliminating DEF injection and even eliminating the SCR/ CAT probably will gain mpgs. Just saying, I have a GDE tune on my Eco Diesel Ram that gives me about 4 more mpgs, but only a few more hp/tq. By eliminating a bunch of the EPA mandated BS, my motor runs cleaner! Using less fuel and having a bit more power is gravy. You ask, how do I know it runs cleaner? In 43,000 miles, the inside of my tail pipes shine like a bottle! My heavy ass Ram has been averaging over 30 mpg winter and 33+ mpgs summer, btw.
