For the last couple of days i have been looking on a lot of threads and getting a little bit confused. I have a obd2 96 prelude h23 with a full exhaust system, true cold air intake. I am planning on putting a stage 1 crower cams, dual valve springs, and pistons to make it high compression. After looking at all of the threads i have been gettting very confused about the h22 pistons. Are the h22 pistons, type s pistons, and h22 type s pistons the same or different? If they are differnt what are the differences.
