when i read that he was trying to unbolt the chassis i about fell off my chair.
Now u can put a LS1 in a prelude. Guy on honda tech did it, just never finished. Ran out of money and time, he sold the car for someone else to finish.
Heres the post
Honda-Tech.com: Hybrid: 1993 Prelude Through hell and back.
but as far as a realistic swap goes, get the H22 and build that. Mahle makes drop in pistons now that don't require you to sleeve the block in order to crank out some nice power. Spend your left over money on that.
I know a guy selling a h22 for 400 bucks, just needs to be reassembled. Perfect opportunity to send the block to United Speed World, they know how to bore and hone a FRM sleeved block. Get Mahle Pistons and some Eagle rods (or whatever rod you prefer) and boost it or run alotta nitrous
