stock H22A4 piston w/ H23 head= 11.8:1 pushing the limits of piston/valve clearance and pump gas if you use aftermarket cams
Mahle H22 9.0:1 compression pistons w/ H23 head= 10.8:1 which is milder than the 11.8 but alot better than the stock 9.8:1

where do you think i said the h22 11:1 pistons would skyrocket the compression to dangerous levels i have heard of bisimoto and so on and so on.... when i said lack of performance parts i mean there is nothing except the valve train that is specified for the h23 and if you look 90% of parts for hseries are for h22.... an all motor h23 is goin to take a whole lot more research than a all motor h22 considering the research has been done for a h22....trust me i may not have it on hand like d with all his research on his computer but i can get to it just like him i have done my research and on my desicion i am better off with my h22....
