Upgrading 4 to 6 cyclinders in '81 Toyota 4WD pickup?

Does anyone know if it would be possible to drop a 6 cyclinder engine into my 1981 Toyota 4WD pickup truck? I love the truck, it runs super well, has only 102K miles, is in great shape otherwise ... but the little 4 banger doesn't allow for much hauling or pull in the mtns with a full load. So: can I upgrade it to more power? if so, what kind of engine should i look to buy? and what's a ballpark on what it might cost me? thanks!

Yes it is possible, but very involved. Personally I would buy a donor Toyota pickup that has a V6 in it. U-hual had a lot of those. It was the really small box truck.

You will need everything basically, the harness, the computer, and anything specific to that engine. Would make it a whole lot easier if you had the donor truck right there.

Oh, and by the way, it is a very tight fit.

The clutch will not engage properly on my 1988 toyota pickup. Already replace clutch master cyclinder and clutch slave?

There are a couple of possibilities; worn clutch plate, failed pressure plate, possible hanging up of the throw-out bearing. Also, some hydraulic clutches have a throw adjustment on the slave cylinder that may need adjustment after replacing the slave cylinder.
If you plan on more DIY maintenance, I would highly recommend buying a Haynes service manual, you'll find the $25 well-spent:
