Today I am taking apart a 1993 D250 for a frame for the 62 crew. Will I ever actually do it? It has only been in my yard for 8 years waiting for me to work on it.

Got a spare 4BT you want to part with, Superdude?

The 4BT responds to tweaking just exactly like the 6BT. I know of several guys, dozens, getting 300 HP & 500 torque out of a 4BT. Common oppinion is they stay real reliable up to about 275+ HP, a little more maybe, then you're pushing it some. That's equivalent to 415 HP from a 6 BT.

Even fairly mild stuff like compound turbos, intercooling, exhaust work and twisting up the pump can make a real ground pounder.

I'm so satisfied with mine's power as is that I haven't even tweaked the pump except for 3,200 governor spring and turn a notch or two under aneroid. I added a HTT Stage II 58cm Compressor to convert from H1C to HY35, to get boost up to 25-28, but that's it.
