    It depends on too many variables what kind of power you will make at what psi. What will you be tuning with, what turbo are you running, what is your static CR? What are the specs on the cams and valvetrain?

    More info is needed before a solid answer can be given. A blockguard wouldnt hurt, but in my opinion they are garbage.

    Eh, I dont know that I would trust a block guard for too much more power than I'd trust stock sleeves.

    yeah they are hype, and i have one... pointless, they dont save a thing...

    the only way a block gaurd truly works is if it is welded in, and if you are going to go through that kinda trouble for piece of mind, u may as well go with a sleeved block..

    becuase a block gaurd is just a false sense of security... imho....

    if you want to run a stock block.. use a built ls bottom end, slap a vtec head on it with gsr cams, throw 13 pounds at it and you will put down 330hp... (if you run a .63 a/r turbo)
    and still be safe as long as you dont get boost happy and crank it up past 15.....

    well i done spend all that money into my ls motor so im going to stick with it so my question is how much boost the block would take ? 350hp? with hondata s200? and t3/t4 turbo

    alot of that depends on the internals u have within the block and the tune....and the type of gas u use, c16 91 93 100+ octane

    Cool

    AS i understand it the blockguard doesnt really do anything but keep the cylinders from flexing and walking around. I wouldnt waste my time on a block guard i would go with getting it resleeved or getting the block converted to closed deck.
    I heard from my tuner before Jim at Motorvations he tunes Hondata, that if you want to do it the right way get it resleeved. Im with Teghoe on this one dont waste youre time with a blockguard resleeve it if you have the money.

    Post I use them

    Supposedly the best way to use a blockguard or the only effective way to use one is to have it installed and then to have to cylinders bored afterwards. Why? I don't know. On a stock Ls bottom end you could probably run 10-12 psi safely with a good tune without any problems. I had a stock ls running 15 and it didn't survive too long.

    my block guard was fucking awesome, not only did it save my block lke it was supposed to, it lasted fine under heavy stress at 400hp on a basicly stock boosted motor.

    Yeah but of much boost were you running and how many miles did you run that amount of boost. Furthermore how big was the dam turbo and how much cfm did it flow? When professionals build these things they either usually close deck the block or resleeve it and i would say most of the time they resleeve it.
    They install blockguards as well but the usually resleeve the block along with that. The only thing the blockguard really does is stop the cylinders from walking around.
    Yeah your motor might have held 400 horsepower. I was running like 11 pounds on a 57 trim turbo with 0.63 exhaust and 0.50 Area Ratio and it made 332 whp 249 ft lbs.
    Im not saying an engine cant sustain this but sooner or later the dam thing gonna go up in smoke pistons will melt, rods will snap, (or even maybe more likely it will damage the tranny), especially if the engine is on stock internals like mine.
    I dont know what engine youre doing this to but i know 400 horsepower is alot for any honda engine to run with a turbo on stock internals.
