Would it be worth the challenges trying to replicate this fabulous powerplant, or just use more available parts to target similar power levels if one were looking to build a separate performance replacement engine? I'm dreaming at this point, but all projects have to start somewhere. Ha ha.
EJ22G [from Wikpedia]
Phase two 2.2 litre closed deck, based on the EJ20K STI engine. Uses identical cylinder heads and turbocharger but with a unique closed deck 2.2L crank case. The pistons are factory forged items, the connecting rods are stock. Although being closed deck, the block does not feature oil squirters for piston cooling, opposed to the EJ20 closed deck block and the USDM-only Legacy EJ22T closed deck block.
