Max 22R Power
I have a 85 22r, and I was wondering what is the max power the stock crankshaft can handle, I was looking at LCE short block kits, but if I don't need a new crank then I will just get pistons, connecting rods, ect

Welcome to the forum.
You would need a new crank for what? Are you wanting a stroker or a high hp motor or ? I guess the stock crankshaft can handle about 350-400whp in turbo application but it also depends on the revs. Then again 22r is carbed, turbo and carbs are hard to adapt.

Im wanting to make around 275-300 whp, and I was going to get a short block kit, so it would handle the turbo, and bored cylinder, when I get the money, but now I'll just get pistons and connecting rods, since the crankshaft can handle it

For one, you're talking about a 85 22R so I moved this thread to the 84-85 Tech Section.
Two, you're thinking about tripling the HP on this engine - that isn't something you do with a few bolt-ons and build as you go. If your goal is a high powered engine then you have to build it as such from the beginning. Why buy pistons now and then bore it out later and have to buy pistons again? If you plan on forced induction then you have build the engine at a lower compression than you would a naturally aspirated engine.
Building a performance engine costs money, time and labor (and labor costs money). To suck every drop of power out of a 22R you'll have to go to the maximum safe bore, chamfered oil holes, dry sump oil system, decked block, stroked forged crank, forged rods, forged pistons and rings, super over-size valves, ported/polished head, performance camshaft, performance rockers, side draft intake manifold, dual side draft carbs, performance ignition system, performance fuel delivery system, custom exhaust, performance flywheel, performance clutch, and the list goes on and on. Then once you plop that engine in the truck you'll have to go back and reinforce everything to handle the power (ie: torque plate, engine mounts, tranny mounts) and upgrade your driveline so you aren't constantly blowing up thirds, twisting driveshafts and snapping axles.
EASILY, you'll spend over $8,000 just to build the engine alone and that is assuming that YOU can do most of it yourself and don't have to pay an engine builder. If you want a powerful 22R engine, you can snag one from LCE for $7,500 or if your goal is to simply put power under the hood and don't care if it isn't Toyota power, you can buy a Chevy 350 crate motor for $4,000-5,000 and throw out over 350hp.
I'm not trying to burst your bubble here, but from my experience there are a lot of people out there that get overzealous about building a high performance engine on a limited budget - those two realms do not belong together especially if you think you can build it up as you go. It doesn't work that way.
