Teaser Article

You pay to read the meat of each of these articles.

I believe no 3.9L has had common rail fuel injection; only the 4.5L.
B3.9L=cylinder bore of 4.02 inches and a piston stroke of 4.72 inches
B4.5L is structurally similar to the six-cylinder B6.7 with both sharing a 104 mm (4.1 in) bore and 132 mm (5.2 in) stroke.

I was following where some guy bought many 4.5L engines; wanted to sell them on ebay, but could not figure how to rig the common rail. He asked. He was told to use blue bird bus engine control. Haven't seen where he is selling the B4.5s yet.

Saw That TOO

Walk in van AC is not automotive. That is a constant RPM engine.

Did not and would not help the fella with the engine lot he wanted to sell.

The ISB 3.9 is a CRD. It's the 4 cylinder equivalent to the engine the currently in the Dodge Ram; think of it as a electronic 4bt. I'll post the link to cummins where they talk about it.
