hey im wondering if u sleeve ur block, will it wear out ur pistons sooner? and what kinda diff. does it make on the engine if the block is sleeved? thanx.

 

sleeving the block means you are getting a
bigger bore cylinder walls so you could acomodate biger pistons
therefore increasing your cc's
and gaining more torque on the low/med range.

so it doesnt mean that your pistons will wear out faster...

 

sleeving give the opportunity for stronger cylinder walls. I would only suggest in applications recieving over 1 bar of boost. It isnt cheap, and workmanship could be questionable.

 

Block Sleeving is the process of cutting out part of the original cylinder sleeves and installing a thicker Iron Ductile Sleeve.

It will actually hold more pressure than stock sleeves during high boost applications.
Another thing sleeves let you do is do a bigger bore on the block. Lets say a regular B18C1 block is a 81mm bore, you can sleeve it and bore out to an 84mm bore. That results in about 2.0L
Almost a .2L increase in displacement which results in more torque and potential power for the motor.
There's more to this process but thats a brief explanation of it.
