if you already have the h22, dont worry about getting an h23 bottom. i may at some point nest year stroke mine out to 2.5 litres..with a full all motor build, how crazy would that be eh! 2.5..with say 12:0 to 1 compr Jun cams..mmmm sounds yummy, ill have that
on a side note, i actually ran an h23 vtec last week...bad result for him, he was shiocked to say the least
