looks like those guys are having a hard time getting the 2.8L 4JB1s and are getting the 3.1L 4JG1T/4JG2T instead. jerry said that one is a little different?
"WHAT I WOULD OD ISTART LOOKING FOR A 4 JB1 TURBO ENG , THEY ARE JUST OVER 105 HP AND IF YOUR TRANS IIS IN GOOD SHAPE IT WILL BOLT RIGHT ON THE 4Y ENG, AND THE FRT ENG MOUNTS ARE THE EXACT SAME SPOT .
IT MAKE A GREAT SWAP AND IS PRETTY STRAIGHT FORWARD , THE 4JG2 135 HP 3.1 ENG WILL ALLSO BOLT UP TO THE TRANS ,BUT HOW LONG IT WOUDL LAST WITH THAT MUCH MORE POWER , ??????????????? NOT REAL SURE ABOUT THE FRT OIL PAN CLEAR ANCE ON THIS ENG , SINCE THE OIL PAN DROP IS MUCH LARGER IN THE FRT , IT MAY CLEAR WITH NO PROB, HAVE NOT SET ONE IN A FRAME YET . GOIGNT O THIS SUMMER , THAT ENG WOULD BE AWE SOME INAN EARLY TROOPER , AND PULL LIKE A FREIGHT TRAIN. . THE OEVER ALL COST WOULD BE A ABOUT 50 % HIGHER THAN TO DO THE ORIG ENG LIKE IT SHOULD BE WITH HI GRADE PARTS , . JERRY"
from what i have read the 4JG1T and 4JG2T are the same engine with direct and indirect injection, respectively. I guess the 4JG2 is more common:

If you don't want to do a body lift, the 4JB1-T (and 4JG2-T) should fit. They're closer to the weight and size of the original engine. Power is about twice that of the diesel LUVs--about 105 hp for the 4JB1-T and about 120 hp for the 4JG2-T. If you're familiar with diesels, you already know that the hp numbers don't mean as much as the torque numbers.
