yes 12HT is Di, they have a seductive idle and a luverly 'rattle' when under light throttle. Still wish they were an easily available engine. They can be given a bit more boost and fuel to produce some very nice torque levels, and are reasonable on fuel if geared right (read HIGH). Factory is 4 to 5 psi region, and very low fuel settings. The crankcase is braced, the pistons are overengineered, and they still run a simple inline IP.

When you say crankcase is braced does that mean it is stronger than alot of other blocks by alot? Is the big ends big like the isuzu ? 5psi boost isnt much even for a big motor how much boost can it run ? Can it be turned up to say 15psi intercooled and fuel up to 600°c like the isuzu ? Yes they do have a nice purr at idle compared to other engines the na 4L's used oil like its going out of fashion I heard but the 12ht is probably a pretty different engine though
