My VQ35HR Build
Curious what break-in method you're using....the typical safe way or the drive-it-like-you-stole-it-to-break-in-rings-better method....
I'm also working with a buddy we are going to run earls fittings on everything and the hoses will b custom made. Will be pretty nice no worries bout hose issues after
Any updates?
I would think that the small iron-aluminum-aluminum boundary layer would help to conduct heat away from the top of the cylinders vs the iron-coolant-aluminum interface.

From a structural sense, the block guards make alot of sense. From the little research I have done so far, it appears that they are not as strong as sleeving, but reduce cylinder movement in high HP builds. Some people are claiming that they do reduce cooling in the upper part of the cylinder, which would not be good. Nonetheless, both the SuperTech and KMS block guards have numerous small cooling passages and, of course, they will need to be drilled out with much larger cooling passages to match those in the head gasket.
Another solution could be to only use portions of the block guard at structurally significant locations. For example, instead of completely surrounding the cylinders and then drilling holes, perhaps weld in a 2" section on the two opposing portions of each cylinder that are aligned with the rotation of the crank.

Quick question. If closing an older block with over 100k miles wouldn't oil sweat out of the block during welding and compromise the weld?

why did you use rev-up cooling system that passes coolant to the heads at the rear cylinders instead of the HR that passes coolant to the exhaust valves??? are you planning blowing the headgaskets out the rear of the engine??? just an observation... and the VR38 deck does have holes to alow coolant to the heads through the gaskts... oil cools the combustion chambers coolant is around the cylinders for quick warmup for emissions... I think that is all of my 2 cents...
has anyone looked into this or have more info about it GTM close deck block. i would like to hear from SAM him self about this block and what kind of temp it gives

thats the block they made for TTG35forT. Its sittin at Japtrix right now awaiting install, so Sam has no idea about the temps as it was his 1st motor out of the shop.

I spoke with Japtrix today, we are scheduled to get started on Sunday.
