WRX internals upgrades


Recommended Posts

so, do the EJ20G, EJ20K, EJ207, EJ20x (2.0L turbo engines) come with cast internals?

 

if they do, finding a good EJ22E or EJ18E would mean they could grab forged (yay forged) internals, that would just swap in (provided as my theory and research conclude that all phase 1 bearing and journal sizes are the SAME) and have a little bit more of a capability of the internals to handle power. this goes for STI people too as far as the rods go. STI people would need to find a phase II EJ22E for the crank to swap. but the only reason they would really want to do that is to lower CR, move to something forged, and be able to have a higher redline. this would make a stock STI engine a destroked 2.5L at 2.3L, and lower the CR quite a bit.
