Block Guard?
Does any one feel these things work good. I have recently done a turbo build and just blew my head gasket and was wondering if they were worth putting in my block. I plan on running no more than 18-19 psi w/ a 66mm turbonettics turbo. Any input would be great. Thanks

I think they help keep the tops of the cylinders from moving around during high rpm, high boost conditions. Lets you get a little extra life from the head gasket.

Maybe but what about in the long run. Most companies won't even touch a block that comes in like that. Block guards are only there to prevent the block from cracking when you crack a sleeve.

block guards are ok but you should only put one it when the block is apart because the block should be re honed after install. when installing a block guard the right way it can and in most cases will throw the stock sleeve out of round. as far as posting goes i never sagest it why would you want to drill holes in a block for any reason. if your going to do it do it right and sleeve it and be done with it then you never have to worry about it again

I thought they were just to keep the cylinders from squirming around. I've seen a bunch of cracked sleeves with block guards.

Yeah, that's why a lot of people don't believe in them.

IMO, leave it open or sleeve it. I too seem to see a lot of damage from guys using these. I have also seen stock sleeves crack just from pulling these out...

Re: (ninesecrx)
I guess that answers my question. I have heard mixed things about these block guards. I decided to go in the direction of being open sleeved and just invested the money in a set of custom pistons from Arias. They say its all in the tune. That can determine how much power and how long an engine can survive. Thats why its important to select your tuner and do alot of research on them to see what kind of track record they have. I let my boss, who is a HKS pro dealer, but specialzes in the 350Z community. I think he used way too much timing on my tune, thats why the gasket blew in just a few days. I guess next time I would rather pay for a tune from a shop that specialzes in your vehicle than getting one for free from your boss that flys all over the country to tune the VQ35. Thanks for the advice and has anyone heard of Maximum Velocity Motorsports in Georgia? Thats where i'm taking my car at the begining of the year to get tuned.
