They said they could get oversized aftermarket pistons big enough, but not o.e.m. I hope I don't have to buy another engine just because o.e.m. pistons aren't available and aftermarket pistons aren't allowed.
as per rule:
Maximum displacement for 2.4L Engines: 2.4110L Liters (147.15 CID)
Must use original manufacturers OEM pistons
