I have a B18B1 with golden eagle H-Beam rods and wiesco 8.5:1 pistons. I dont have the money for a sleeved block so I was thinkin about a block guard. The thing is I heard that a block guard causes hot spots in a turbo motor. So my question is, is this a good idea or not I have alot of mixed answers, whats ypur opinion?

 

There are a thousand opinions in the search archives.I don't see a few more being any more helpful.

 

My opinion is that they are a waste of money. I have never installed one but I firmly believe that a stock sleeve would break just the same with or without one.


Careful tuning and a smart owner seems to go a long way....

 

If a block guard is to be used, the best way to install it would be the way JG and other engine builders do it. They hand fit the block guard to the block for a close fit before any other machining operations are done to the block. The block guard is then TIG welded in place. Skip welding is used to minimize distortion to the rest of the block. After welding, the builder machines the deck of the block flat, then the final bore machining is done. In my opinion, this is the correct way for a block guard to be used. At the very minimum, the block's bores need to be machined after the block guard is installed. Again, in my opinion, a block guard should never be installed in an assembled engine that is sitting in a car with its head off; instead, it should only be installed when building a new engine and the bore honing can be done after the block guard is installed.
a website said that

 

Personally i would rather run stock sleeves without a block guard. From what i've heard, all they really do is help you sleep better at night. If the sleeve is going to crack, a 1/4" piece of metal isn't going to stop it.

...also, you have Eagle rods, not Golden Eagle

 

sleeving ur block will be the only thing that will help you sleep at night. that with a good tune and u'll be sleeping like a baby
