What other cranks can the F22B accept? What cranks will an H23 accept?

Ive searched and need more help I know PirateMCfred and Rick Solis were compairing notes. What rod/piston combo's will yeild a higher C/R for an H23. I know piston diameters will not allow the F22 to use an H pistons but what about building an H23 with other H motor parts to yeild a higher C/R? Any ideas?

 

Bump!

 

try using the word "crank" when you search

 

Thanks wise guy so which of the 918 results was it?

 

its the domed pistons that are high compresison. check out importbuilders.com They have everything you could want engine wise. Im sure they do high compression pistons for your motor.

 

ok maybe I need to clarify what I am looking for.

I know what equals higher compression engines, what combinations will raise compression in an H23 when combined. Ex. H23 block with JDM H22 pistons and H22 head will move up to 11 something. Will that work with just an H23 block with H23 head or will there be clearance issues? Would changing cranks with another crank push the C/R up? If so what cranks will work. Most of what I found reguarding cranks were for B series motors. What combinations will raise compression in an H23

I think the crank is just going to change your redline abilities. Because the crank is one of the big components that determine stroke right?

 

The crank must also affect rod stroke too though wouldnt it?

 

I'm not sure if this will help you any but this is what I've done
with a H23 block. We took a F22 crank and pauter rods with
13.5 to one compression. The crank will bump the compression
ratio up to 14.1. Now of course the block has darten sleeves.

It is the ONLY component that determines stroke.

The H23 head will yield higher CR than the H22 head since the combustion chamber is smaller in volume. If you have an H23 you can swap in USDM or JDM H22 pistons for a higher CR, using the Type-S pistons will result in over 13:1.

You could also mill the head a thousandth or two to bump up some points.

 

So are the H22 rods and H23 rods the same length?

 

gernerally held to be accurate:
h22 rods = 143 mm
h23 rods = 141.5 mm (same as f22 rods)
f23 rods = 140 mm
f20b rods = 145mm

So no H22 and H23 rods are not equal. Usually as stroke increases the rod gets shorter.

no... the H23 and H22 rods are different lenghts. All I was saying is that if you have an H23, you can swap the H22 pistons onto the H23 rods and get a bump in CR. If you use pre-97 H22 pistons, then it is a straight swap... with 97+ pistons you will have to get the H23 rods rebushed to accept the floating wrist pins used on the 97+ pistons.

 

A longer stroke will always increase the compression as will an over bore (assuming the same head and gasket thickness is used). Unless you raise the deck, the rod will have to get shorter or raise the pin (compression height) in the pistons. We recently did a short block for a customer with 97mm stroke, 89mm bore, Pauter rods, Custom JE pistons ( for 89 bore and 13.5:1). It was an H23, but will work in any H series. We had to align bore for 55mm main journals, but some blocks already have these journals. Naturaly we had to sleeve it to get 89mm bore.
