so this is my first diesel swap project, i want a 4bt cummins in my '91 ford explorer. i was wondering if there was anyone here that has done such swap and about how much did the swap cost? i would really like to use my 5 speed trans that i already have, is that possible (or wise) to keep the stock tranny? what kind of milage did you get after the swap? and did you take pics and do a write-up when you were done? any help at all is greatly appreciated!!
