Yet another 2.2T owner seeking sanity check on adding displacement

[myflat6]

here is the marketing speel (copy paste) from LN on the thermo/cooling and other benefits. Take it for what its worth

Nickies have more surface area and up to twice the thermal conductivity of factory Mahle cast aluminum cylinders

Nickies have as much as four times the thermal conductivity of cast iron or ductile iron cylinders

Nickies have up to 50% greater tensile and ultimate yield strength than OEM Porsche cast aluminum cylinders

Nickies are stronger and more ductile than any cast iron, ductile iron, or aluminum OEM or aftermarket cylinders

Nickies allow for larger slip-fit and machine-in sizes than previously available with cast iron or aluminum cylinders

Most Nickies cylinders for Porsche applications come half-mooned for improved crankcase windage, which is typically good for 8-10hp over factory Mahle non-half-mooned cylinders
