3.5 turbo; seeking pistons and cylinders input
 

(x-posted from the Rebuilding forum)

Engine is a 3.5L (3.2 case bored to 105 mm), twin plug, turbo. Heads, ancillaries, case and related bottom end bits are all sorted and in hand. Looking for input on pistons and cylinders, which I need to source.

Pistons - this is a 91 octane build, so thinking 8:1 CR. 2618 probably a must. That means… CP (preferably in their X-forging) or JE (preferably in their FSR forging). Any others?

Is there a “mature” CP/JE/other piston out there that fits the above bill? Considering that my engine recipe is pretty mature/sussed-out by now, I’d rather avoid roll-my-own custom unicorn pistons.

Cyls – are Capricorn cylinders suited to 2618 pistons, thermal expansion-wise? Certainly the LNE cyls are, though they're pricier.

Trying to keep this build pragmatic, so pretend you’re spending your own money here in the responses.
