OK, So I so again i'm planning on running 1 bar or 14.5lbs of boost. I have crower pro rods and cp 9:1 comp. forged pistons. I read that the crank can handle 400 hp and so i'm not replacing that, I'm trying to get out of this as cheap as possible. So I only want to crack the block open once and be done with it. So I have seen 2 different designs for blockguards / sleeve savers. there is the scalloped design That has big grooves cut outs along the edges or the basic solid rings with holes drilled in them. Know I hear that the scalloped guards are designed for better coolant flow, but are they as strong? Do you have a preference or experience with either one of these designes? do you think I should spend a lot more money and just get it sleeved? Anyways let me know what you think, especially if you know what your talking about.

Do it right and get it sleeved. Do a search for why the block guards can creat big problems for you.

In my opinion you would be better off running with out the block gaurd and just getting a really good tune. Best case would be to sleeve the block, block gaurds do way more harm than good. What engine is this and what turbo?

b16a, turbonetics t3/t04b, what kind of harm does a blockguard do??? The only thing I have heard about are hot spots in the engine due to improper coolant flow.

Block guards are a total waste. They do nothing for increasing structural rigidity in a non-knocking condition that a properly tuned engine operates within. The block guard will not save the sleeves; they will crack if the engine knocks. They also expand at a quicker rate because they are made out of a different materiel than the sleeves, typically 6061 aluminum, this rapid expansion causes them to oval the cylinders.
