okeh so im a bit of a nub with modding my car so i have a question..or several rather... do you have to sleeve the h23 to run forged pistons? or is that only the 22? im getting some car stuff for xmas and was thinkin about maybe some high compression forged pistons/rods but wasnt sure what else that involves...also i havent really modded the car at All yet, so would it be a better idea to just go i/h/e for now and maybe cams/pistons/rods later? this car will be n/a... also if you have any recs as far as i/h/e if i go that route lemme know, thenks

 

Yes you have to sleeve all the H series motors when running forged pistons. do a search, this has been covered 10 million times before.
