Yeah id suggest B18b1 for a cheap generous upgrade since theres SO damn many of em on craigslist all the time or do what i did, hold out for a good b18c1. But u gotta understand that just cuz u might be able to buy a Lon block and transmission for $2000 doesn't mean that u have $1000 to get it installed. There are lots of little things like mounts, shift linkage, engine harness or modifying your own etc thy u need to buy for the swap
