Start out with a set of tool steel connecting rods (Carillo for instance) at around $2500.00 a set. Then buy some custom forged pistons, Venolia or something similar- - - -$1,000.00 +, then fabricate a set of cooling nozzles to spray a constant stream of oil at the underside of the pistons to keep from melting them under full power. That's going to require a very high volume oil pump- - - -possibly a belt-driven one from the crankshaft hub since the distributor shaft and gear won't be able to handle that kind of load and a standard-type pump won't be able to supply enough volume. Once you get the bottom end beefed up enough to survive, then turn your attention to the cooling system- - - -run a BIG oil cooler and an oversized radiator, plus an air-to-air intercooler to make that extra air the turbo is pumping into the engine dense enough to be worthwhile, not so hot and thin it does you no good. Now for the cylinder head- - - -break out another few thousand for a highly modified head to handle all that extra intake volume, and a carburetor big enough to flow the air and mix enough fuel with it. Then build a huge exhaust system to handle the turbo outlet volume.
After you give your checkbook CPR for a while, sit back and admire your handiwork. You can do that every time you nail the gas pedal while you're waiting for the turbo to spool up and develop some boost!
Alternate suggestion- - - - -purchase a bone-stock Cummins turbo Diesel in a RAM pickup, and start out with more HP and torque than the 292 can ever hope to make- - - -with a factory warranty to boot! And spend a lot less money!
