I am considering an F/I installation, but I understand our stock blocks are hard-pressed to function well under boost. I know a tiny bit about sleeving and nested sleeving. What other methods are available to tie together our open decks to make them stronger? I also contemplate adding forged pistons and rods, not to mention an upgraded tranny valve body. I guess while the head's off, I should consider new cams, valves & springs, and retainers as well. Your thoughts?

In order to increase HP [reduce friction losses] they used lighter rings with less tension, lighter pistons, lighter rods and a much lighter crankshaft and narrower bearing all around.

It is not just the cylinder sleeves. The previous versions [3.0 liters] were bullet proof from a block stand point] and lasted way too long. How many new car buyers care if an engine can last 300,000 miles +............when does diminished life affect resale value?

 

now If I just get the pistons and the rods without sleeving the block, will our stock block can handle..hmmm let say, 500HP??

From what I've read, our open decks leave the cylinders unsupported/braced on the open end. Under heavy boost, the cylinders oscillate... kinda like six wiggling fingers. Over time, the cylinder walls may work-harden and crack open like dragon eggs. I'm trying to figure out how to tie the cylinders together so they can handle boost without all the oscillation.

There's a group buy on my350z.com right now for Pauter rods and Aries pistons... it ends soon and is a pretty good deal, mine our already paid for!
