2.2
2.2 Nickies & JE pistons. 84 mm, compared to 85mm Nickies & JE pistons. Would like to know what displacement the 85 mm would be. Will be building up a 65 aluminum case with all the modifications, using 2.4T ( opened up ) heads & IDS Webers with SSI heat exchangers & a like new 71 exhaust. Would the 85 mm be any great advantage? Thanks for any input.

Hear good things about them. And, what are the alternatives ie, availability.

Again, why Nickies? Heck you may as well bore the cases and go up to a 92 bore with Nickies.
As far as 85mm bore, I doubt you will notice any difference over the 84mm. I believe you can bore the stock cylinders up to 87? That may be a consideration.

Essentially, want to keep the 2.2 vibe with more reliability. Want the aluminum cylinders reliability & weight savings. Hear all other cylinders; steel, have out of rounding issues with time & mileage. Thanks.

Lot's of choices in Nickies. All about the same price.
Looks like for slip ins you could go up to 87.5mm https://lnengineering.com/products/aircooled-cylinders-pistons/porsche-911-1965-77/porsche-911-22-875mm-nickies-inc-95-1-je-piston-set.html If it were me I would go with these. https://lnengineering.com/products/aircooled-cylinders-pistons/porsche-911-1965-77/porsche-911-27-93mm-nickies-inc-95-1-je-piston-set.html

Hello S hammer , I'm surprised you're building a custom engine and do not know how to calculate the displacement . How will you know the compression ratio ? I certainly recommend some homework . There is a cliche that most anyone can turn some nuts to put together an engine , the hard part is making it run right . An engine with 85 mm cylinders would be a 2.25 liter .

Good point. I’m just wadding in to this endeavor. You’re right about the homework & I plan to get more informed about these calculations. Have to admit, numbers are very intimidating for me & in recent years have a greater interest as they relate to an engine that is very intricate & genius in design.
