that does suck... but you still have your h23 tranny? then just go with a h22 longblock. you can get them from hmo for 1200. I know I certainly wouldnt want to go from an h23 to an f22. but yes the tranny will work, intake manifold will work, header will work but maybe different lengths. but I would definetly look into getting an h22 longblock if you still have your h23 tranny it shouldnt be too much more than what you got for your h23. oh and yes there are forged f22 pistons. raceeng.com
