"I NEED A 2.3 TURBO THEN"
No..., you need a donor car, an engine hoist, the capabilities to weld and fabricate sheet metal for installing the motor mounts and engine compartment alteration. You will need a transmission capable of handling the power output. You will need (at least should) have an 8" rearend. You will need (at least should have) a larger radiator. You will need an external high pressure fuel pump.
Lastly you will need 200 to 400 hours to do this right. Yes, there are people who say the did it in a weekend but they probably had a '74 and up car, knowledgeable friends helping and all the parts ready to go. The car was probably "functional" but likely far from proper.
Don't assume you can just drop a turbo on an engine or simple slide a turbo engine into a Pinto (especially and early one).
To answer your question: just about any turbo motor should have forged pistons. The 2.3 Turbo motors came with forged pistons and a compression ratio conducive to the turbo boost.
