Hello everyone. M52b28 aluminum single vanos block var. Applied 87.70mm sleeves and working with 85.50mm honda pistons. 89.6 crankshaft 135 rods. I have a new project in mind. Using 86.00mm piston. The block has 87.70mm sleeve. And the 85.50mm is already working. It has 2.2mm sleeve thickness. It will be reworked for the 86mm piston. The thickness of sleeve with 86mm pistons will be 1.7mm. My question is, is 1.7mm sleeve thickness safe? Have you ever heard of aluminum block and 86mm pistons. And Your think. I'm sorry for my poor English
