Gen 3 2.0 Project
So im doing a little project with a Gen 3 2.0 block from a 2011 Buick Turbo. As we know the Gen 3 2.0 has no sleeves which means you cant bore it because of the special coating on the bores. Soooo I have a set of Ductile Moly Alloy liners made .090 wall which is 50 percent thicker than our stock liners. So after a visit to the best machinist on the east coast I have this.
All I need now is a rotating assembly. Should be good for 600 HP

It cant be bored unless you add sleeves because of the coating on the aluminum cylinder walls. The cylinders as cast are twice as thick as the older blocks making them very strong. No we bored the cylinders out and sleeved it back to stock bore . Super strong now and can use any type piston available. No need for a girdled block now.

The original bore is just coated/treated/hardened whatever. You can't bore it without removing the hardened area and leaving you with soft aluminum. He bored it out to accept a double thick sleeve and the n bored out the sleeve bring it back to the original 2.0 L but with a thicker sleeve so you don't have to girdle it.

The direct injection 2.4 looks similar to the 2.0 except it has sleeves and a whole engine can be had for $750. It also uses the LNF head used on the 2.0. Cheap source of parts. I was thinking of getting a set of sleeves made which would shrink the bore to 88.5MM to make it super strong.
