as we know (or maybe don't know as the case may be) honda designed it's engines with the cylinder walls floating in the water jacket (no the don't actually float, it's just at the top of the block (the deck) they are not connected to the rest of the block in anyway) This is called an open deck design.
works great for cooling but put any pressure on the side walls and those cylinders will distort or crack or throw a rod right through them... anyways the block gaurd reinforces the op of the cylinders and therefore allows them to withstand more side loading... however the cost is less water jacket coolant flow due to the restricted opening. basically it's a trade off.

first: how much do you think it would cost to get this intalled ??
second: is T-toping similar to this ??
thanks again

it shouldn't cost much at all to install as long as the head is off. If not then it should cost as much as gettin a headgasket done.
Its sort of like t-toping a block. Same idea just cheaper....a lot cheaper. T-top sleeves are expensive, very expensive, but worth it i am sure. Sleeving an engine would be a lot better than simply using a block guard but sleeves alone are like $1000 plus install which i am sure costs an arm and leg.
T-top sleeves turn your engine into a closed deck design, this is what a block guard tries to accomplish but costs a fraction of the price. It essentially adds a strength to the top of the cylinders, as gatherer said, but i don't know about compromising coolant flow.
Take a look at where the holes in the headgasket are that the coolant flow through versus the shape and design of the blockguard i have for sale.
I don't see how this blockguard would block coolant flow. Now i have seen cheaper designed block guards which simply have holes cut out that would probably block coolant flow....like this one.
But overall i would say a block guard is cheap insurance for someone running forced induction.

OK, here is the real deal. block guards are a waste of time, te never fit all the way around the water jacket leaving gaps everywhere (so whats the point?). you MUST bore the cylinders after install because they walls distort from the block gaurd going in. Tsleeves are the only correct way to go, the are precision installed so they fit all the way around the water jacket. as well i have never seen a block guard with holes the same size as the holes in the head so yes they do restrict coolant flow.

I agree about tsleeves being the way to go but not everyone is made of money.
I've seen block guards that fit perfect, but i've also seen bg's that don't fit so good and like you said don't touch all of the way around the water jacket.
b16civic:
When, or if you have ever installed a BG did you weld it on or just tap it in and use locktite?

Torrey, it's not the search part, it's the honda-tech part. We have enough people here on this board who can help with all of everyone's questions. We don't have our own online community (which does more traffic then HT i might add) so that we can refer people to HT.
Not to mention that everyone on HT is a retard.

I gotta agree with both of you on this one... but if we refer everyone to HT then we really have no need for the whole forum altogether. other than "where in the GTA can I get XYZ?" which would **** me right off 
peace on earth and happy new year everyone!
