Just wondering if anyone has experience with these? I know about the JUN kit but way overpriced. Was wondering if anyone has used the Paeco kit? Obviously their crank isnt forged so does anyone else think this would have problems handling say 650rwhp? I was reading through search and Z from Japan was going to try a bore and stroke up to 3.5L. Anyone else give this any serious consideration or know if he actually did it? Lastly, everyone says it will affect your ability to rev, but anyone actually know by how much? Would this effect even be noticeable? Thanks.
