How is 87 turbo engine different from NA?
An aqaintance is considering getting rid of his 87 T2 - basically clean but shot apex seals et cetera. Can I use the motor out of my N/A 87? If not, what about used japanese market motors? They were almost all turbo, wren't they?

The turbo and NA engines are completely different. Among other things, they have different irons, housings, rotors, lower and upper intake, front cover, wiring harnesses and ECUs. There are many more differences, but suffice it to say it is not a direct swap.
As for J-specs, just remember that you're buying a wrecking yard engine. You might get a bridgeported monster with a T66, you might get a stock engine ready to blow. It's a gamble.

Do you reccomend buying a TII engine? Or a j-spec

I am sure a couple of other people will back me up on this, but IMO, J-spec engines are nothing more than decent cores for rebuilding. Any motor that has been sitting in some Japanese junkyard for the last 10 years is going to be in poor condition. To top that off, most of the ones that were in good condition were found 3 or 4 years ago.
Notice how most USED Japanese engine sellers are saying no warranty or only a 90 day warranty on rotaries anymore... its because they too know that the motors are all crap from sitting or worse and won't last more than a couple of weeks.
Now, don't get me wrong... I think they are great for conversions (NA to T2), but only when rebuilt first. But the odds of getting a Jspec that will not need a rebuild in the next 5000 miles is almost 1,000,000 to 1.
