The major considerations are pressure and heat.































IF you added a turbo to a stock engine, engine detonation would be a factor, you would HAVE to start using 93 octane, and possibly even add ethanol/methanol injection.































It's very possible that you could get away with just 93 octane, bigger injectors, high flow fuel pump, and a dyno tune if you added a small turbo and had it limited to 4-5psi without any other internal modifications. With the addition of long tube headers, you could possibly get away with 6-7 psi.































Of course, this would only be a roughly 60 horsepower increase. Turbos are a lot of money and modification, holes have to be drilled into the block for oil circulation to be routed to the turbo, etc.































If you don't wish to spend the money on upgrading the internals, I would suggest sticking with a small, self contained supercharger setup. They have enclosed SC kits that only require maintenance every 100k miles and do not require any of the modification for lubrication/cooling.































This is all just guesstimation, I don't know exactly what that little Toyota motor will take, but my guess is 4-5 psi as long as you have plenty of fuel for lubrication and the proper octane to prevent detonation. Best of luck.
