Re: forged pistons?
I used Speed Pro L2256F + .030" OS forged pistons in my 4.3L TBI engine. They produce 9.7:1 compression ratio. . However, those are flat top pistons and a turbocharged engine will need a forged pistons but with a 12 cc dish to reduce the compression ratio to about 9.2:1. A .200" deep x 3.00" OD dish can be machined in the Speed Pro pistons if you cannot find a forged piston with a dish. The L2256F 350 CI V8 Chevrolet pistons will work in a 4.3L V6 engine if the engine is completely precision internally balanced. They have ring lands for 5/64" top, 5/64" second, and 3/16" oil rings Don't get pistons that use the 1/16", 1/16", 3/16" rings because they will not last on the street and they are designed for floating pins, that is, a racing engine.
Maybe someone else is aware of a forged piston that is a direct replacements for the Chevrolet 4.3L V6 turbocharged engine.

Probe makes a forged dish piston:
(Link was the first google one I found)
http://www.coasthigh.com/Chevy-350-20-3cc-Dish-Top-FPS-Pistons-p/p2441f.htm
These are functionally equivalent to the TRW 2441F.
There are many, many aftermarket options...SRP/JE,Diamond,Wiseco...

Re: forged pistons?
Keith Black ICON forged pistons for 4.3L V6 engines are now available. The word is finally out how failure prone hypereutectic pistons are in high performance applications. KB has decided to start making forged pistons or go broke. Speed Pro/.Sealed Power (made in India) uses VMS75 low expansion aluminum alloy so their forged pistons can be set up with tight cylinder wall clearances just like hypereutectic pistons for better oil and compression control. Tight cylinder wall clearances allows the car to pass today's more stringent emission requirements.
