Honda 3.5L V6 swap
#130
The last time I talked engine swaps with Shawn Church, his eyes lit up when HE brought up the J series engines. The sand rail guys get 450whp with a single turbo and stock internals, and 250-275whp NA with a stock ECU that's had the immobilizer chopped out of it. A quick check of the Acura forums shows all sorts of Franken swaps with J37 cranks, hi-comp pistons and wilder cams. Oh, and Honda.
I bet the weight would actually be LESS than a turbo or Rotrex car, with engine weight more mass-centralized. And last I saw that they made a new oil pan that looks less like an asphalt anchor.
I like the concept. But then again I'm a glutton for punishment.

Seriously, do you think the Lakewood housings are that much heavier than stock? For example, the T5 trans is only 75lbs but I don't know if that includes the housing or not. If it does, then that's Miata territory weight for a trans than can take 330wtq. That would be enough for a built J36, and not too much of a weight penalty.

Are we talking about T5 or TKO? T5 are nice but you have to basically DIY it to get the gear ratios you want. The lakewood bellhousing doesn't fit any T5 transmissions, if I recall.
TKO is like 90-100lbs without the bellhousing. It looked like the best option to me, especially with the lakewood bellhousing. But then I read a bunch of posts regarding shift problems at high rpm and kind of gave up on the idea.
At this point the transmission I'm interested the most is the BMW E39/E46 6-speed manual (Getrag 420G). It's rated at 370ft/lbs, weights 100lbs, can be had for reasonable price and has good gear ratios. The issues is that its short (probably hard to mate to PPF) and has a flange on the output shaft, instead of a spline, requiring a custom drive shaft (since you can't use a slip yoke). And of course, no easy way to mate it to any engine.
edit: to answer your question, I'd expect a miata-sized aluminum bellhousing to weigh like 10lbs.
