Another update: engine should be shipping out of Miami this week (as soon as I pay for it!) and I should have it 3 to 4 business days from the ship date.
The fellow from the importer tells me that it's one of the cleanest he has seen, totally complete with - get this - the top-mounted intercooler! I guess this is the 4JB1-TC model. Not sure of the difference in power output, but I'd guess it will be an improvement on the non-intercooled model, if only a modest one.

Still looking for ideas on a radiator to use. Also, the Troopers with the intercooler used a hood scoop. Ideas on fabricating one? Maybe score a stocker from New Zealand (does it bolt on?)? Or convert to a front-mount intercooler?

If this goes well, I'll post the importer's contact info for interested parties. He claims he's got access to 15 more of these right now.

That's all for now. I'll post photos when I receive the engine.
