Diy block sleeve
 

click the link and comment. I personally wouldn't do it myself but have heard great results. A friend of mine just ran his b series build on the same sleeve setup and hasn't had a problem yet. Just found it to be out of the ordinary and different.

sorry if its a repost.

might be interesting to try it on a spare block and see how long till it blows up! :D

My buddy has made 5 or 6 passes on mid 20's psi or so. Hasn't had any problem with overheating or the material breaking down. If you take your time and do it right I believe its reliable. His setup is a bonestock b16, just a new head gasket, oilpump and waterpump. And besides the arp headstuds and acl race bearings.

Oh and it will probably hold till vtec kicks in yo!

Technically thats not a block sleeve. Thats 'closing the deck' so to speak. It helps the cylinders resist walking.

It has worked well for medium boost constantly.

put some concrete in them shits

so whats this exacly? is it the same as a blockguard?

Yeah... it's no different than a block guard you can buy stupid cheap on eBay.

im pretty sure it failed in the end. then again it was 36psi on a crap tune

People have been doing cement for years. most shops do it and dont talk about it
