its not a big deal to remove them.. people have been plugging oil squirters for many years on other honda motors with no problems. Most engines dont use them from the factory

What is done to the k24 crank to work with the f20? Are the k24 cranks all alike or is one preferred over another?

All that needs to be done is to have the lip for the flywheel machined away. I believe there are only two different part numbers for the K24 cranks. All K24 motors use a single part number except for the first generation TSX's. Even the older TSX's changed to the same part number as the Element and such.

On the K24/h22 combo. what Material do you guys to notch the bottom of the block?

IMO it doesn't matter as that's a garbage build.

Has anyone done this with success yet? Would love to hear about results...

mine ran for a short time due to parts failure. i made 272 hp and 195 tq rev to 8300 rpm. im doing an LS swap now, tired of high strung motors with little power and no torque

What parts were you using? Did you buy a complete stroker kit or did you use H22A connecting rods? What caused the engine to fail?

I am also interested in stroking my s2000 to 2.4 liter.

so even the inline pro s2k k24 stroker kit will have that lip on it?

That seems awfully high to me - equivalent to revving the 2.0 litre 84mm crank to over 10,000rpm

To match the piston speed of the 84mm crank at 9k, the 90.7mm crank would need to be capped at 8375rpm (which is why Honda reduced the redline to 8k - to give a safety margin). The 99mm crank only needs to be doing 7,673rpm to match the piston speeds of the 84mm crank at 9k.....

This is what happens to even tuner prepped cars if they are revved too high :

Obviously Honda have built in some safety margin with the standard limit of the 84mm crank, but I wouldn't be wanting to be going much beyond a piston speed of 84pfs without some significantly stronger rods / rod bolts.
