Here is my build gsr block and head. No boost planed. All motor. Stock thickness head gasket. skunk2 70mm t-body and intake manifold. Aries forged pistons with a +5 dome. Skunk2 valves, springs, retainers, pro2 cams. ARP head studs. I have a block guard but have been reading that they can cause hot spots on sleeves. Also can rattle? I tried to install the block guard with no luck. Its a very tight fit and I don't want to mess the deck up on the block. I got the block guard just because I was going to have the head off and figured it would be a good idea to get one but now I am not so sure. Looking for some input. Install block guard or forget it?

You don't need a block guard on your build. Leave it out. I wouldn't run one myself.

My build is close to yours and I will not be running one, I say don't use it.

MR.johnson

if your going to make more power than stock sleeves can handle. sleeve it.

if not your fine.

block guard will make your motor overheat, means less coolant will go through between the cylinders, thats what happen to one of my friend fully build gsr motor, its similar to your set up, i say dont used it.

manicmechanic

So the stock sleeves should be able to handle what I am doing to it. I forgot to that I also have a lower temp t-stat and fan switch installed on the block. If I remember correctly I think the t-stat is a 60 degrees celsius and the fan switch is an 80 degrees celsius.

dc2_poojan

yea the stock sleeve will be no problems if your not going over 82mm bored, any bigger than that i consider resleeving the block, unless the car is only drag only car not daily driver but still its not a good to have a block guard, with no block guard you can still daily drive the car quiet sometime...

MR.johnson

no. but they still suck.

manicmechanic

No the car is not my daily driver. I have a ef that is my daily driver. On nice day I can take my motorcycle into work. But for the most part the ef is my dd and winter car. Don't get me wrong I do plan to take the eg that I am building to the track at least once. One of the reasons I am building this motor is because I sold me other ef with an ls motor in it. Should have built that motor and kicking my butt for not building it.....Nothing I can do about that now.

So my question to you all would be why would big companies like Golden Eagle, Supertech. Sell such item if its not good or useful?

DDTECH

It has its purpose. For instance, i run one on my b20vtec. On motors with stronger sleeves like a GSR or b16 build, its not needed. It just provides a peace of mind really.

For Sleeves that can easily be distorted(b20 sleeves) its a good thing to use, if funds are tight and you just want alittle extra. Its almost to the same point as to why people run girdles. You dont really need it, but people want to run one for a peace of mind. If a motor isn't properly balanced for the rpms it will see, a girdle is a good idea for added safety for the bottom end.

00Red_SiR

It's called marketing. Sell what people will buy, not what they need. If there's a buck to be made somewhere, people will make anything and tell you why you need it. I'm oversimplifying the reasoning for the block guard here but it's basically true.

egb18c5

thats exactly what made this honda scene into the way it is now. people are believed that they need this part or that part to make power etc.

manicmechanic

Well I think I am going to ditch the block guard. Like I sayed when I put this post up was that I was going to have the head off. And I was thinking what the hell why not put a block guard in. But now I am not going to. I will have to get pics of the build up here soon.

AlHimself

id run a girdle over a block gaurd anyday.

do LS have a girdle as standard?

N/A

No the ls doesn't but they make aftermarket ones

Then it was installed incorrectly or it had another issue.a block guard just doesn't start making your engine overheat

"Fully built" lolz

It is simply a placebo.

Not quite a placebo. I had my B18 a block bored for next size up pistons. The shop recommended a block guard, but I said no. I then provided a deck plate for the honing stage, and after it was in place the cylinder was out of round just enough that I had to go up to the next size piston. The shop does championship level drag cars, so they normally know their stuff - but this surprised them. They really should have waited for the deck plate before doing the bore, but they thought it would be ok.

The pertinent observation is that if just adding a deck plate distorts the cylinder so its a bit out of round, then so will bolting on the head. I authorised instalation and welding in a block guard, and then they rebored and honed it with the deck plate. Price adjusted.

For info, race orientation engine, 11.7 cr pistons before milling etc, likely to end up 12.5 cr when b16 head b18c crank and b18c rod combination and milling added.

I have a D16y7, ebay turbo build, gonna have YCP pistons with the custom long rod no block notch set up. Planning to make around 400hp. Will I be safe without a block guard??

All dependent on your tuning capability and fuel used. Cylinder sleeves on that D16Y7 has had a record of supporting that power with those things.
