If I where to use these kits to increase engine capacity. Why is it seemingly impossible to find high quality 87mm High compression ratio pistons? I want 87mm Pistons, 12.5 cr or 12.7 cr. Or is it possible to modify the HKS Pistions before ordering? I want higher compression ratio and bigger bore. Also, I need the valves to match.

-I dont care about FI(Forced Induction), as I am a NA (Naturally Aspirated) fan, and will remain that way.

with the cost of those is probably cheaper a long block fa24 and goes faster..

Umm the prices online are 30-40k for this are you really going to spend that much on a gt86 motor :eyebulge:

^^
Waayyyy cheaper. I've seen entire FA24 running assembly with trans locally for 9k.

It is impossible, so I decided to improvise. Custom made 90mm 11.5:1 pistons and custom sleeves. Modified OEM head gaskets. Just under 2.2L on the stock crank.

Sleeves were made by LAsleeve. They'll likely make you another set if you ask them. Some of the forged piston manufacturers will do custom stuff. Gaskets are trickier... I got greedy and had to machine a bit out of stock ones to get 90mm. If you keep it sensible the stock gaskets are good for 89.5mm
