Well the packages have started showing up for my turbo build...here is the first one
Race Enginering block guard I paid about 110 for it shipped i think.



The machine shop told me that they would reccomend this guard cause they use it the most. Thus they know how to install it properly. I posted a while back on sleeves, block guards, and machine work and from what I read it machine work a lot to do with how well of a machinist they are; so I bought what they used and feel comfortable with.
Thanks for Reading

looks nice and i hate to give bad news but that same blockguard gave me overheating problems so i had to get it taken out. pain in the ***. i switched to a golden eagle blockguard and had no problems after. if i were to use another one id go with the STR or the golden eagle design

I am about to go with a GE blockguard. If you put this one and GE beside each other you will see why 99B16Si is having better luck with the GE. The GE just has bigger openings for the coolant. BUT, as we all know from this forum, it is NEVER the same case with every engine even if they are exactly the same. I wish you luck, and I believe that success with a blockguard is 99.9% dependant on the installation.

thats why i switched from the GE blockguard to GE sleeves

looks good, to race engineering, great service and quick shipment. i got the sleeves for my last motor from them

It's clean but I hate blockguards, sleeved blocks or just plain old stock sleeves for me... Just my $0.02

why?

V-SPEC 1

GE block guard.

the reason people hate block gaurd is because they go in the coolant jackets bloking flow. also the will have contact with the walls were coolant would normaly be. this causes hot spots. and because of the bloked cooling passages you have a greater risk of detonation.
it is the same principal with open and closed deck sleeves. closed deck will only be practical if you are running alot of boost, otherwise there is no risk of not having the top of the cylinder walls braced.
so basicly block gaurs don't do you much good

They gotta work for somebody or else all these companies that make them are headed for bankruptcy.

They make people think they work, but I doubt that that little blockguard will really stop the stock sleeves from cracking under extreme abuse. With the money you are spending on the block guard and machining costs, you can pay for part of sleeves, and then have a really reliable motor!

Most of the problems with the sleeves is poor installation. Everyone smashes the guards level with the head of the block and then has it machined. The guard should be inserted at least 1/4 of an inch below the surface of the block and then the block needs to be machined and cleaned. Block guards will reduce the risk of sleeves cracking, same idea behind pinning sleeves.

Which also has some of the same inherint problems as a guard.

The thing about actual aftermarket sleeves is they are designed to hold more pressure themselves where as blockguards transfer any extra exerted pressure into the actual casing of the block... We've cracked stock sleeves before, **** happens but how many times have they cracked from the very top where the blockguard sits? About half of the time... More often than not you'll just blow a chunk out of the sleeve half way down... Like I said maybe it's just me, I absolutely will not build a motor with one... Just my $0.02 again

Yeah I thought that the holes were a little small for the coolant to get through; I guess Ill send it back. The machine shop tells me they throw these things in all there honda motors that they build....Of course they didnt say how many of them were successfull either. I cant afford sleeves other wise I would get them; I feel with mild boost I can have fun until I sleeve my LS block for LS/Vtec and then really make some power
GE block guard it is?

heheheheh me too

I did a little EXTRA research today. I looked at golden eagle block guard and it does look like it flows better. I called Race and talked to them about it, and they havent heard any problems with there guards. I called the machine shop (Buds Machine Shop) which were the ones that reccomended me to go to Race, and he said he has done over a dozen of these things. He found that if you place the guard 1/8-1/4 lower then the deck it makes a little water pocket that helps the flow better. Im going to trust their words on my project. I think it comes down again to the machinist and how well they do their job.
99b16Si- I hope Im not going to have the problems you did; if I do you can come smear my face in it later
Thanks guys Ill keep ya posted!

If your motor is blowing sleeves halfway down, I would say that's detonation rearing it's ugly head. Sleeving will offer more protection from detonation, but the bottom line is that enough pinging will kill any motor, sleeved or not.

Im having a shop help me turbo the block. Hes told me a million times mild boost would have ran on my stock rods, pistons and sleeves, and i bought a lot of aftermarket stuff to build this thing up. Stop posting about me getting sleeves; this is about block guards
thanks for trying though
Hes turbo'ed a GSR with 30psi on a STOCK gsr; he just had aftermarket pistons thats all...he runs like a 9.25 qm!

Actually you're right, we've never blown a boosted motor and actually they've all been my friends nitrous motors... He had no signs of detonation prior to blowing up but I'm sure that's what took them out... Playing with the Digi6 too much, haha...

I bought the race eng. block guard for my car. I was originally going to drill out the holes bigger to get a better coolant flow, but I didn't want to change the structually integrity of the brace so i left it like it came. I have not had any overheating problem after about 7000 miles. Here's a pic:

Thanks for the pic. Your post is re-assuring

I think that everyone has forgot the orignal idea behind block guards. Why do some of the engines also use block girdles? The idea is to tie everything together and to keep the parts from moving independently. The same goes for the block guard. It is not going to strenthen the sleeve to much. The idea is, unlike a full cast block, honda's sleeves under high rpms will shift. This shifting, especially under boost and high rpms, will increase. The block guard is to help minimize this.
notice my block guard is also 1/4" below the deck

I was told this that makes a HUGE difference...
