Or buy a Vette for the same money and have an all around faster car stock.

Typically going 2.5x the stock hp will be volitile.

CSG Mike said it best, to check with a reputable builder.

Yeah im definitely gonna do that, now since we have a recall on the valve springs and the engine is gonna have to come out so what i thought was since the motor is out and head off might as well forge it, oh and i work for toyota as well they seem to be ok about that so far,

As others have said 400 whp with a good turbo kit ie JDL, MAP or ptunning running e85 with supporting mods will work. How long will the block last is anyone's guess and have money ready to rebuild the block when the time comes

Reliability is pretty much on you. Someone can give you the best golf club in the world, engineered to drive the ball 600 yards with a swift swing. If you don't have the form or skill to hit it true, it's just going to be another bent club.
