Did a little digging on the F series and it appears the F22 and F23 do not share the same crank nor the same bore diameter.

F22A/B bore and stroke is 84mm/95mm. Whereas the F23A bore/stroke is 86mm/97mm.

I dunno how that works, but apparantly the F22 has a longer stroke then the F23. Maybe the 2mm in bore makes up for it.

Good luck, hope this helped a little.

Not sure where you're getting your info from, but you should stop using that source.

F22A/B bore/stroke is 85/95 while the F23 is 86/97.

To answer the OP's question, you cannot swap cranks. Reason being is because F22's have 50mm mains while F23's and H22A4(obd1 only i believe) have 55mm mains.

Even if you manage to fit the crank in an f22 block, you have a much longer stroke, which will make your pistons meet your valves.

You should be a little more respectful when correcting someone. By the way, I was 1mm off due to a typo.

Since you like to get butthurt easily and like to take things personal online, you weren't off by only 1mm.

You said "84/95", that's 1mm.

You also said "86/87" which in that case you were off by 10mm.

Do I have to kiss your ass now that you're an admin? You certainly never said anything about my posts before, and I've always had the same "tone".
