block guard?

[HiTeK 510]

what is this and what does it do? is it an alternative to rebuilding engine to stronger internals?

[LudeAction]

all i know is my buddy has one (his only internal mod) and he runs 15psi daily

yeh i need some more info on this topic cuz im thinkin of turbo'ing sometime soon...dunno if i should replace stock internals or go with this "block guard"

block guard will save your motor, honda motors are all open deck except fot the h22. this means that when you open the motor up and look at the block you can look straight down nect to the cylinders. a block guard closes the deck and stregthens the block tremedously. it will help prevent cylinderwall blow out and will also stop cylinder sway which is when under boost and sometimes under high RPM the cylinders rock back and fourth this is bad the block guard holds them in place. great mod. i highly recomend it. but if your going turbo do it right the first time and get pistons and rods. dont want to crack a piston and blow some rings cuz then your gonna have more problems.

blockguards prevent proper coolant flow which leads to high engine temps which leads to detonation

is that bad?...sorry dont kno much bout this subject

This is what I know,

Honda Engines are built with floating cylinder sleaves, there is a space between the cylinder sleeve and the engine block that allows for better cooling and lower operating temperatures. This is called the water jacket. This is not a bad thing, but under heavy boost the cylinder sleeves can shift around within the waterjacket, this is a very bad thing. A block gaurd reinforces the cylinder sleeves to prevent the cylinders from shifting in the water jacket under heavy boost.

The internals of a stock engine are built to run within a certain rpm range. This includes everything from the crank shaft, piston rods and pistons, to the valves and valve springs. The reason that we end up reinforcing the internal components of our engines is because we increase the operating speeds of those components and the pressures that those components are being subjected to. A drivetrain that is built to run at a maxium of 8500 rpms will not last very long if you are reving to 9500+ rpms. Increasing the maximum RPM of your engine is a good way to get more power out of your engine. This is true with both Boosted and NA engines. To do this you need to rebuild your engine with lighter and stronger internal components that will allow your engine to move faster with less stress.

If you are going turbo and going to keep your rev limit the same, and not go with massive amounts of boost then I would say, yes you could get by with just a block gaurd and maybe some stronger piston rods and of course adequate fuel delievey and spark.

IMO if you are going to install a block gaurd in your engine block you might as well rebuild the bottom while you are in there...it will save on labor costs if you decide to do it later.

damn, I must have been writing that post for a while, I can see that I have repeated most of what has been said.

acurasquirrel is also correct, a block gaurd will keep your engine from cooling correctly.

Honda Engines are not a good base for turbo applications, but I don't think that has stoped anyone yet.

im thinkin i just get tha block guard along with all other internals (rods/pistons/camshafts)...doing so, will this "bulletproof" my car even if i am goin to go at high revs (~9000-9500rpms) since im doing both block guard w/stronger internals?

They have supports that allow coolant flow I forget who makes this but they support the cylinder walls and still allow proper coolant flow this is what you need
