werd, I used to be a weight ninny too, but its seriously like a 40 lb difference. The AC on your d16 weighs that much, so yeah, its pretty negligible.
Honestly, for the price, the H22A is a phenominal engine and has way more torque than you'll ever get out of that b18c without a turbo. Throw a turbo on a B18C, and you've spent $5k+ all together and offset any weight advantage you might have had by going b-series.
The swap is a bit trickier, if you're planning on doing it yourself, but HASport has great instructions with their kit and there are TONS of online resouces on how to do the swap, so I wouldn't worry about it. In your shoes, I'd get the H22A in a heartbeat.
