replated cylinders + JE's, anyone try 'em? Options

[brp914]

mahles run into some serious $ when you get into the 3.2+ size. Anyone try the replated cylinders from ebs or others? Are they a long term reliable solution for a street car, or is it better to bite the bullet and sink 3.5k+ for the real deal? TIA

I can't actually say that I have the answer to whether or not cryoing changes the actual hardness, but I do think it's a good idea to cryo a used cylinder. The process does provide a more thermally stable casting and does relieve any stresses that have built up over the years. I actually used cryogenics for a batch of Nickies where Alcoa forgot to stress relieve the extrusion. Big difference in how it machined before and after dimensionally. Not so much so when it's already been stress relieved from the factory. Castings have been shown to have the biggest improvement from the process.
