Some guy on the Accord forum posted he had his f series bored .20 over. I thougth these motors didnt come with iron sleeves.???? Can you bore or even hone these blocks since h and f series blocks are designed alot alike?

 

it matters if he got forged pistons or cast pistons

 

He used the Race Engineering pistons and crower rods. But how do you bore a motor with no iron sleeves??

 

to put forged pistons in any f or h engine u got to re-sleeve it
and u can bore it how much u want then

 

either that or he had .25 overbore FACTORY pistons.

 

Is it possible to just replace the factory pistons with forged pistons and not hone or bore the block? Will you get a good seal for the rings?

 

If you can clean up the cylinders and stay within the F22 oversize bore limit (.25 over...85.250-85.260mm, .50 over...85.5-85.510mm).

Per honda factory manual...Reboring limit .050mm max
