turbos are very tricky. first if u want it to be efective you must have some low compresion like at least 8 ta 1 and forged pistons,rods and even crank if u want big boost. if u use stock componets u will sieze a piston. thats when the piston gets so hot from the turbo fumes it expands till it gets stuck in the block and the next thing is bam the connecting rod blows through the piston so build up that engine

 

You can run stock engine components IF you don't exceed the safe boost range. I have a friend who turbo'ed his '96 *onda and has been running 5-7 lbs of boost for about 5 years and 45k or so miles. He runs the crap out of the car constantly and nothing has broken but the tranny, stock internals.
But I agree with Mustang1968, with twin turbos on a smallblock, why detune all that high dollar stuff just to use stock internals?

 

Turbo engines do not strictly require high end parts. Turbos are easier on parts than any other power adder at the same power level as well as naturally aspirated. The toughest thing on parts is when the piston has to change directions. With forced induction this is somewhat cushioned. This along with the fact that RPM kills parts and turbo engines dont need more than 5000 RPM or so to make good power makes stock parts very usable. Of cours if we start talking about double or triple power output then you need to upgrade. BTW the piston stuck in the bore thing is not accurate.

Please look through the old post for more information. This has been discussed over and over in detail along with books I have recommended many times. Come back with some questions after really looking at what is already there for you.
