i know that the h22s need to be sleeved cause that was the last motor that i owned and worked with for turbo but what about the k20z1? does it need to be sleeved in order for it to be able to fit forged internals for turbo? i searched and havent found anything like this about the k20 motor. am just asking cause i know some honda motors have iron sleeves like the accord f22 motors and some dont.

 

anyone>?
