F24C Long Rod Engine Build 2.4L
#221
Everyone thought my Deck Plate motor wouldn't work either, but it does. Everyone also though my deck plate was a waste and over thinking/engineering to make a stoker kit. In fact I love driving around with this motor much more than my K24 S2000. But we needed to succeed and make one step to be able to move onto this next step. No one would make an adapter plate/deck plate for a K head if they didn't have K24 Long Rod rotating assembly already in mind. We'll see how this comes out.
Here is the F24 deck plate with K head gasket over it. The head studs all line up. And 3 of the oil return holes are exactly the same on the exhaust side. The others overlap with is good. I just need to make the bottom of the plate F series and the top of the plate K series. First is the mock up and making the K timing tensioner work. We may even be able to use a standard K24 timing chain now, since the deck plate makes our block height the same as K24.

I know who you are talking about. That was an i-vtec conversion still using the F20 cylinder head. That required modifying the head a little bit. I'm going to try that first on the engine we already have with the deck plate. But the real beans will be in the future if I can get the K20 head to work.
Imagine the use of any K series cams, with a block that already has the same K24 rotating assembly. The internals don't know the difference if the block code is an F20 or a K24. Because we already have a K series kit for the S2k, I'm in great position for this mod. I already have a K to S2k Header, Intake Manifold, ECU, Engine Harness. The idea makes me excited to have all the direct fit block assembly, engine mounts, AC compressor, Trans, clutch, flywheel etc. And all I have to do is make the head fit. The biggest obstacle is making a timing chain tensioner location. The F20 head holds the TCT. The K block holds the TCT. We will have to modify the block a little for TCT location. I already bought a K20 head assembly! Progress is coming!

I prefer the K Head for 50 degree VTC & have variety of camshaft options.
It's as having TODA 2.2 Stroker Kit in a K20 w/ stock F Series Rod Stroke Ratio
I have outline(s) ready for this K on F Build

Probably requiring either custom pistons or custom rods and a sleeve, it should be possible to take it to 2.5 without much drama.
That engine has a 26mm air restrictor. Note the US Formula 4 cars use a Honda K-series, Japanese F4 cars use a Toyota motor.

Personal want to see a K24 Block, F22 crank, F20 (sized rods) with custom piston and K head for turbo use. Get a nice rod ratio, and nice thick head on the piston for boost. I have a spare K24 block..... Hmmmmmm
