Hey everyone i wanted to know if i could use my f20C crankshaft on a stock f22C block? Would it work with the f22c rods and pistons? No modification to it?

I believe the only difference mechanically between the 2 are the crank,rods,and pistons. That being said, you should be able to swap the entire reciprocating assembly into the f22c block.
The crankshaft must match the rods. F22 crank with f22 rods. F20 crank with f20 rods.
Check out the s2000 section as well. From what little I know about s2000's, your idea should work.

Ok thanks for the info. But would i be able to do. F20C rods and cranshaft. with f22C. Pistons???????? If anyone can let me know asap!

If the compression height of the pistons are the same, it should work. What the compression ratio will be, I don't know. I would think f22c pistons would lower your compression vs the f20c pistons since more stroke with same dome volume increases compression.

Would i still be able to rev. To 9k with this setup?????!

Factory redline of the f20c is 8900 right? So I think you should be ok if you wanted to hit 9k

Dimensionally, the F20C and F22C blocks are the same. So, using a F20C crank, F20C rods, and F20C pistons in a F22C block makes a F20C engine (with an F22C stamp on the block). It will act just like a F20C engine. Using the F22C pistons will yield slightly LESS compression due to a slightly smaller dome volume and shorter install/compression height.
