If you have a 1994 Land Cruiser then you should have an inline 6, not a V6. If you have a V6, you either swapped out the I6 or don't have a Land Cruiser...
You should have the 1FZ-FE engine. If you want aftermarket, a place to start is IH8MUD.com, along with Specter Off Road
www.sor.com and Toyota Racing Development (TRD). J.C. Whitney might have stuff for you. I've heard of 80 series being turbocharged, supercharged, along with the usual mods for off roading. The aftermarket is there, but for boost you might need to search for things not in the USA, instead the Middle East has the best things. If you want, a machine shop can custom make an adapter for whatever kind of boost device you want to apply, be it turbo or super. Good luck!
