I found a compression cart but it only uses stock pistons. H22a1 block H23a1 crank H23a1 rods 8:5:1 h23 pistons 88mm bore. .51cosmetic headgasket or OEM. 28? Trying to find out what the compression ratio is going to beWith 8:5:1 pistons or if I should go with 9:1 or something. I'm confused with the whole h23 crank h23 rods h22 pistonsAnd that puts you at 12? I want low compression. So the h23 pistons drop it down to 10? On h23 crank and h23 rods. But IRead the h22 and h23 are the same highth crank to piston top. Just moreStroke.? I'm just confused if someone will let me know the CR I willbe looking at with h22 block h23 crank h23 rods h23 8:5:1 pistons. Not 8:5:1H22 pistons. I think the compression highths are different on the twoPistons.... help or point me in the right direction please.
