Today I ordered a set of 4 ECi Tapered-finned Nickel+Carbide Cylinder Assemblies for my IOX-340S engine. The set also includes 9.5:1 compression pistons. Since I picked up the engine case, the crankshaft & camshaft a few weeks ago, I’ll start purchasing the accessories over the next year so that when I get back I can put this thing together with Tom Schwietz.
A nice thing about buying the cylinder assemblies as a set is that ECi ensures that all the cylinders are flow matched, making for a much smoother and efficient engine.
Here’s a representative pic for context.
