change pistons

[92smokeaccord]

is it hard to change pistons in an f22a1.some one told me u can remove the oil pan and disconnect the rods to pull the out the pistons. is this true or do i have to rip the block apart.

You have to remove the oil pan and disconnect the rods, yes. It is quite involved, but with the right tools, it's not extremely difficult. Just know what you're doing before you take something apart.


And what do you mean "rip the block apart"?

I'm thinking he means taking the head off and diving into it that way.

i meant kinda like a rebuild apart but only as far as pistons. take motor out put it on a stand and dissasemble like a rip and rebuild.

What are you going to replace the pistons with? Stock or performance parts?

i need new piston rings. i got some extra $ so i figured id buy the bisimoto perfomance pistons.

If you're doing this, I would remove the block from vehicle and have it prepped at machine shop. You need to make sure the bores have proper piston to wall clearances, etc.

If you skimp out, you could have compression issues and piston blow by, not worth it.

Performance and backyard don't go together for reliability. Now, if you were just installing new rings on stock setup, OK.

i would have to have my block bored any way cause the pistons im lookin at are 86mm. +1 over stock.

I wish I could say that.

Yes, if you go that way. However, there are pistons of stock bore/85mm too. Regardless, you still need to maintain P to W clearance, which on Arias/Bisimoto pistons for NA are .003"

i really dont want to 86mm but i couldnt find 85mm performance pistons. if u know of some please leave me a link or 2.

I used the Wiseco 11:1 85.5mm pistons (purchased from this site) I also had my block bored and honed.

They also have 85mm as you can tell as well. Honestly though, I would go with Bisi because no matter what you will have to have the cylinder walls worked for proper clearances.

if you are changing to different pistons/rings, it is highly recommended to get AT LEAST a hone. even if they're stock pistons from another used car, or brand new stock pistons, it will need a hone. part of the break in process is the rings creating a unique groove with the cylinder walls. when you swap to different ones, they won't match up.

if you're going with larger pistons, you will need it bored out (bore is the diameter of the piston/cylinder wall) the larger pistons like you're wanting you will require the engine to come out of the car and then stripped to just the block. the cylinder walls in the block will then need a larger bore done by a machine.

to answer your question, you will need to have the engine out and machine work done if you go with larger pistons. expensive, but may be worth it in the end if you want the most out of your accord.

Wiseco has 85mm pistons with higher than stock compression ratio.

kinda like when u change the clutch. the old grooves dont line up with the the new.
