Im not a big fan of the 4.3L either, but if it's what he wants to build than all the power to him. The only way I see it running worth a damm is either with boost, or n20. I don't think running 9's, or 10's with a 4.3L in a S10 would be out of the question, but would take some $ for the engine to handle it reliably. You would need to convert the block to splayed, 4 bolt mains, short hard block fill, Good pistons, H beam rods($$$ there different than a 350), Custom turbo cam, valve springs, and push rods, port the heads to flow 250+ CFM, machine the valve guides down for the springs, and extra lift, balance rotating assembly(which will likely need mallory$$$), head studs, cometic gaskets, etc. There will probably be well over $1000 in machine work alone.
After your done with that swap over to the marine style intake manifold, and start building the turbo kit. I would start out with something like a Master T76 p trim, 68AR.
The reason everyone is saying LS swap is you can get a 5.3L from the wrecking yard, swap the cam & springs, build your turbo kit and your done.

that right there said funding is a issue. but its normal for people who wanna build something thats gonna be insane amount of money to say money is not a issue.
we all like to joke around here a little bit cause we have all been down the v6 rode, at least i have. you getting mad feeds the fire. if anything we are helping you but trying to show you the cheapest best bang for your buck route.
