Why not spec longer rods and shorter pistons?

I I think the idea is to keep the moving components as OEM as possible. But I'm sure Ballade will comment on this.
The amount of material in the piston from the top of piston to the first ring land is not that great. I suspect that will be the reason.

It just seems like, to me, they're overthinking the shit out of this.

I doubt it's worth the money to create new rods for this, but I'd be curious to see you guys test the F22c crank with the 9mm deck plate to see how far up the powerband shifts. Either way, props for thinking outside the standard industry box!

Thanks. We don't plan on creating new rods for this engine setup. Everything we need for pistons, rods and crank are all provided by Honda. This is a custom engine block case, with the idea of using all off the shelf Honda parts. Just not S2000 F series parts. Current stroker kits are the ones using custom rods. Shorter custom rods. Minus the prelude type S rods.

Again I really like that approach. I'm having an engine built in the Uk to replace this Urge pos I have, and the race engine builder is adamant that all the Honda parts are far better and more reliable than 95% of the aftermarket items. OEM parts being modified, like shaving cranks etc isn't ideal either. I guess as an engine builder you get to see all the failed bits coming back and see what works and what doesn't. OEM parts are generally built, balanced and tested to much higher standards and designed to last a lifetime assuming they are kept within a reasonable operating window. The tricky bit is selecting the right parts when you go away from oem...!

But I'm all for an oem Frankenstein build

Took a photo of a K head gasket over an F head gasket this morning...... Temptingly similar. 2 passages are moved slightly.

Ummm....one method uses custom length rods....another method uses a custom crankshaft, this method uses a deck plate, longer timing change, but all the other moving parts are OEM. Seems relatively simple as an idea.

Ballade, could we also get a rough estimate in cost of parts and/ or labor (and if possible current/ expected cost to date)?
