I think there's a communication barrier here. I'm not sure what the difference between full swap and stock swap is.
If you're just looking for a stock replacement, you'll have a harder time because those motors have had some issues with crankwalk, they are new and therefore expensive, and the 90-91 "6 bolt" motors are easy to swap in and are also pretty cheap. Don't waste your time with JDM here, some people don't seem to know any better and think JDM mitsu motors are better (I know many honda motors are better JDM than USDM, but there's only about a 4% chance that when buying a JDM motor you'll get one of the very rare motors with slightly higher compression, a larger turbo, or larger injectors...and those are the only improvements, otherwise JDM and USDM are practically identical). Stock these motors are good for around 400hp no problem, and if you're looking for more you can always build one. My suggestion would be to find a good used 6 bolt, or build a motor from the ground up.
