search for blokhard or blok hard in your favorite search engine, make you own guard.

If you really want a block guard be sure to buy the STr one (www.strspeedlab.com) this is the only one to deliver high flow for coolant

This is what i plan to do. I want to get a b18b1 install it in a 1992-95 hatchback and then boost it with a garret t3/t04e turbo. I want to push 10psi on race day and 6-8psi for daily driving. I plan on getting 450cc injectors and apexis Super AFC.Do you think that i need a block guard for this setup.

dont get a block gaurd.

uhm also, if your putting devcon in your motor and thats the only motor u have.. uhhhhh its not a proven method yet lol one person has tried it.

i would experiment with a D series before u do that on a B series.

Yeah, don't get the blockguard. I regret putting mine in. I was told that it slightly warps the cylinders and causes blow-by. If you were to install one properly, you would have to hone the cylinders afterwards to true them. If you were to go that far you might as well do it right and get it sleeved. I would think if you had a good set of pistons and rods, you wouldn't need to worry about the block at only 10 psi. If you ever seen a blockguard being installed, you would change your mind about it. They were meant to be press fitted and most likely you will use a hammer to put it in which obviously isn't the greatest method.

dr.boost is absolutely right, its not worth it unless you plan on dragging the car... and at that point get a machine shop to do it so that they can get the block guard deep in to the coolant channels so that it doesn't warp the tops of your cylinders during exhaust strokes. Also they will have to do a little machining (honing and possibly notching) to get it in there and make really good use of it

Cylinder walking isn't to bad on a honda, if this was a bigger engine (like a V6/V it would probably be more then worth it to do it.

I made a bunch of separate rings on a lathe and cut them into sections to be pushed down into the bores. I also used screws through the side of the block to hold them in place. Using this method I was able to use the screws to apply pressure and true up the bores which were out of round. Gave the bores a quick hone to rough them up and put in new rings. I run about 8-9 psi and don't have any trouble with the motor.
