high compression pistons without sleeving block? - Honda Prelude Forum

I am planning on getting some 11:1 compression pistons. My question is can i get the pistons with out sleeving the block?

It is my understanding that ify ou changes the pistons you have to sleeve the block.

If you get the Type S pistons, I do not think you would have to, but I may be wrong on this one. I dont know the difference in sizes.

I saw a site the other day that was selling Civic Type R and Integra Type R pistons and you could order stock or .40 over sizes... I can't remember if they had Type S pistons or not...

I thought re-sleeving of the cylinders was reserved for FI applications?

Someone can correct me if I'm wrong, but resleeving is necessary because aftermarket forged pistons like JE or Arias etc are harder than the NickaSil sleeves in our block. Over time the piston will wear the sleeve into an oval shape causing blowby because the rings don't seal, loss of compression and a slew of other headaches. Cost you a lot more in the long run.

I'm not sure if you would have to resleeve if you go with the Type S pistons though...

You do not have to resleeve with the Type-S pistons and they come in .25 overbore sizes. Type-S pistons will give you 11:1 compression.

Dirtylude is right. You don't have to resleeve for Type S pistons and you can get them in stock diameter and 0.25mm oversize.

There is a lot of debate as to whether or not resleeving is necessary, but I don't think anyone has tried aftermarket pistons without resleeving to see if there would be a problem or not.

I know of that site, or a similar site and they sold type S pistons. Like I said before, you wont need to with the type S ones and they are 11:1 so that would be the best way to go.
