i just recieved a set of cp pistons for my f22c build and the part number is the same as f20c but i ordered for f22c. are the pistons the same? it doesnt make sence...
F20C 87mm Bore x 84mm Stroke - 8.815" Block Height (from BC's website)
F22C 87mm Bore x 90.7mm Stroke - 8.815" Block Height
the difference in stroke is f22c is +6.7mm
Engine Series Pin dia B E bore Length B E width
2.0L F20C S2000 early .906" 2.008" 6.023" .935" (from pauter's website)
2.2L F22C S2000 late .906" 2.008" 5.902" .935"
the length difference being f22c is -0.121" which is -3.0734mm

now if the piston is the same that means the piston will stick out of the block 3.6266mm

any thoughts?

 

The bore size of the pistons are the same. What is different is the small end of the rod. The placement of the wrist pins are different since the stroke on the F22C is not the same. So due to the rods being different the pistons pin hole placement is different. Hope this helps.

 

ok thats what i though the pin height has to be different

 

ok so i called inlinepro and they say its the same piston... i hope this works.

 

The 2.0 liter stroke is 3.307 and the connecting rod is 6.024, the CP Piston is 1.131 compression height. This comes out to 8.808

The 2.2 liter stroke is 3.570 and the connecting rod is 5.895, the CP Piston is 1.131 compression height. This comes out to 8.811

There is only a .003 difference, depending on who manufactures the rods.

The wrist pin in both is a .905

i just realized this. i feel dumb
