David (of isuzudieselswappers.com) uses an unusual approach. On the 4BDxx engines, there are two sections to the bell housing - the engine section that attaches to the engine block and extends back a ways past the flywheel. This section also provides the mount for the starter. Both the Isuzu automatic and manual transmissions attach to the back of this "engine section" of the bell housing. David attaches his adapter plate to the back of the engine section also and then the GM transmission bolts to his adapter plate. He drills and taps the flywheel to which he mounts an adapter to which the GM flexplate attaches as his adapter was originally designed for an automatic transmission. The end result is that you have both the flywheel and torque converter if you use an automatic transmission or two flywheel, the Isuzu and the GM, one behind the other if you go with a manual transmission setup - a rather novel approach!

I've never pulled the head on a 2T but pictures that I have seen show a removeable precombustion cup in the head and the piston is essentially flat whereas the 1T has a significant combustion pocket in the top of the piston but the head is flat.
As far as the intercooling, the turbo setup on the 1T and the 2T appear to be identical except that on the 2T the output of the turbo is routed forward and through the intercooler which is mounted in front of the radiator then back to the intake whereas on the 1T the turbo output is routed via a 2" pipe directly to the intake.
