Do h23 rods fit h22 type s pistons without any modifications?

 

no, i believe you have to modify it to a floating wrist pin

 

what parts do i need to do that ....and where can i take that to get it done a machine shop....or is it easy enough to do myself

 

take them to a shop, you can leave them press fit, but they will need to be honed out a bit. they will have slightly too much press fit the way they are now.

option 2 is to have them bushed and then you can have a floating pin.

 

will there be a clearance issue with the head since the h23 rods are longer?
what engine is it going in?

 

its the h23 block with the h22 head......using h23 rods and h22 type s pistons.......i thought the h23 rods are shorter than the h22 rods just the h23 crank has a longer stroke right?

yes h23 rods are shorter.

5.572 H23 rod
5.636 H22 rod

 

if you use the H22 pistons with a stock H23 crank and rods, they are going to be sticking out of the block by .018

 

so you can have the rod machined to have a press fit? no problem to the type s piston?
how much would they need to be honed out?

is there any difference on the piston between floating pin en pressed pin?
thnx

 

from what I understand the pin in a type-s piston is about .001" bigger than the regular h22 pistons. i think some people have left it alone, but imo thats a little too much press fit.

type-s pistons aslo only take type-s pins.

 

so no prob with the type s piston if i have a type s pin pressed fitted...?
