I am getting ready to pull my engine to work on a few things and I figured while it was out i might upgrade my pistons. I have an h23 and I would like to run usdm h22 pistons not the type s pistons. I have heard it can be done but I would like to know what all needs to be done to run these pistons. There is a lot of controversy on whether or not there is enough clearance with an h23 head. I basically want to know if it can be done and what i need to buy/do to run these pistons. If it isn't really feasible I wont mess with it, because it works now.

 

Shouldn't be any extra work needed

 

They will stick out the hole .020, but the head gasket is .026, so as long as you run stock cams and nothing has been decked, you should be fine.

 

Keyword being "should". Don't take any chances. Check your clearances.

 

Alright thanks for the help so ill check my clearances to make sure everything is good and hopefully install some h22 pistons
