ok my car is a 2011 and it broke a piston ring. The piston looks perfectly fine from what I can tell and so does the cylinder wall. So I'm wondering who makes a drop in piston / rod kit. I see complete rotating assembled from mmr and jdm but not really just a piston/rod combo. If I'm pulling the motor to fix the one piston I feel like I mine as well spend the little extra money and upgrade them all as well. Is balancing going to be an issue? I was going to reuse stock crank. I will also probably install a set of cams while it's at. Car will be a fully bolt on e85 tvs. So maybe 8-900 hp.
