Hey guys, I was wondering what Resleeving an engine block means and whats involve in Resleeving the block? If someone can go in detail in what is needed and what the process are to resleeving the block so I can understand what it means and what are the benefits of it. Also, do you need to take the block out of your car and send it somewhere to get it resleeve or can you do it with the block in the car? Thanks for any info and replies. Appreciate it.

 

To resleeve a block, you bore out the engine and replace the cylinder walls with ductile iron sleeves. Then you bore out and hone the sleeves to the right size for whatever size forged pistons that you want to run. Basically if you want to run a lot of boost or nitrous(100+ shot) then you need forged pistons, and you can't put forged pistons into an H22a without resleeving the block first. You have to take the block out of the car and give it to an engine builder or Golden Eagle can resleeve your block for $900, but you have to send it to them.

 

Resleeving a block means to press the cylinder walls (sleeves) out of the block, and then replacing them with a different material. This is really only needed for a bullit proof motor, or very high boost. Forge piston's are very good for both, and they are also fall backs to bad tuning. remember bad tuning with kill anymotor, ductile iron sleeves w/ forge piston's can be hurt easily. this has to be done outside the car, and only let a trust worthy motor builder do, you do not want to make a sleeve sink when the motor is running.

 

Wrong.... The old sleeves are pressed out, not bored out of the old motor..

 

And that is why i made my post.

 

If you plan on running any type of forged piston, you will need to sleeve it. Ductile iron sleeves are not necessarily the best either.

And no, you can't bore the stock sleeves. Well, you could, but it'd be a disaster.

 

I figured, just backing you up so the orginal poster would know which is right..

 

Thanks for all your replies and info guys. you've all been very helpful Would I need to resleeve my block if I want to put Type S piston in? What I wanna do is an sort of an all motor set up but with a little help from a 55 shot Nitrous just to give it a little more boost. What are the compression specs on the Type S piston and would my block still be able to handle the 55 shot with the high compression domed Type S piston? again.........thank you for all your help

 

You don't have to do anything to pop some Type S pistons in, just pop them in and GO! That is the beauty of them

 

To put in type S piston's, you'll need to hone the block, and get new rings. i'm not sure what your compression would be with stock cams (Vs type S cams) but i'm guessing itd be in the 11.2 range. type S cams have alittle more lap, and thus lower the static compression of the motor. Yes, you'll be able to run a 55 shot if you have an equal amount of fuel coming too. i personally wouldn't recommend the 55 with that high of compression.

 

Ok........thanks for all your help guys.
