Hi Can someone please help me getting my head around the diffrence in a sleeved block and using a block guard.

1. do you use a block guard aswell as a sleeved block or do you just use it when using stock clyinder sleeves?

2. last of all what would you say are safe WHP figures for running stock a stock sleeved bottom end with a block guard? with forged pistons and rods?

pics of the diffrence would be very much appreciated!
Thanks in advance

cheers,
Mark

First of all, a sleeved block is totally different than just a block guard. Sleeves that are aftermarket and can hold up 40psi with proper tuning. While stock sleeves, even with a block guard can only hold up to around 25psi with proper tuning, but not for long. A block guard is a piece of metal that suppose to help reduce the chance of sleeve wall. While the aftermarket sleeves are 2 times as thick and are made of iron, which is much stronger than the stock aluminum, iron sleeve.

It depends on you power goals, if you want more than 500+ hp in general, then I would sleeve the block. It you want less than 450hp, than I would stay with the stock sleeves. It's all personal preference, and some will say that you should'nt use a block guard, but it does'nt hurt to have that extra piece of mind. Yes someone will argue this point, but there's no proof that block guards are harmful(Darton has them attached to their aftermarket sleeves.)

Goodluck with making your decision, it should be based on your HP goals.

the size of the sleaves between oem sleaves and GE sleaves are about four times the size.

Why do people insist on basing the limits of a motor on psi alone? 30psi on a t25 is different than 30 psi on a t3/t04e 57 trim.

I will have to dissagree with you. PSI will be the same no matter what turbo you are running. The volume is what will be different, therefore the bigger turbos will allow you to make more hp/tq.

Pounds Per Square Inch(PSI), It's the same no matter what your talking about. Just because you are a smaller person and can swim down 500ft in the ocean, does'nt mean you will not meet the same pressure of the larger person at 500ft. Can you see me drift, pressure is the same. And if you call any company about there aftermarket sleeves, they are rated on PSI.
