I checked the locations that B Serious mentioned above - nothing available. I know I have to be patient.

Any other recommended sources for block and perhaps crank?
Do you feel an F22C engine can be rebuilt for decent long term reliability if done correctly?
if i dont plan to go FI, should i revert back to OEM pressure plate (id need to buy one) instead of the ACT plate that i have?
Thoughts about a K24 swap? I've seen the kits from companies like Ballade Sports. Is that all you need plus the engine?
Is everything preserved like A/C when doing the swap?
Sorry for all the questions.

 

I'd expect Inline Pro to be the most experienced rebuilder. Your block would likely need to be sleeved at this point which is not going to last as long as an OEM block. InlinePro should be able to build a "reliable" engine but it's not likely to last 200k miles.

ASMotorsports would be my first choice for a K-Swap. Plenty of places make mounts but the wiring and electronics would be of more concern to me. ASM offers a factory Honda harness and modifies it. I'm sure they have a working configuration for A/C and everything too.

 

If you use stock parts and don't have to machine the block, or crank, long lasting rebuilds are possible. It's when you use aftermarket parts or have to machine the block that you end up with issues. As long as the parts are within spec they can be used. Someone had to assemble that engine in the first place.

This block for an F20 looks like it's in decent shape.

Here's a F22 crankshaft. Most of the 06+ stuff is in the head. The tricky bit would be to get the bearing clearances on the crank and rods on point.

My issue with K swaps is that good K series engines are not cheap, or you'll be going the Frankenstein route. Also the initial swap is going to run you around ~$8-10k depending on the engine and miscellaneous parts. That said, a K24A2 with a K20Z3 head will wipe the floor with any F2xC engine.

 

If I go kswap (and I may) it will be a K24 and will likely be this package. They have a super good rep and have done some great builds. Hard to beat the price for having 99% of what you need. Have to modify (or have them modify) the harness and provide the ECU you are going to use. F2K Swap GLTC Track-spec Engine Package. ASMotorsports Store (shopasmotorsports.com)

Have autocrossed with some of the guys running their swaps and the cars seem very well put together and perform great. And the tq curve difference appear to make a hell of a difference in the cars. And yeah, have already been talking logistics of the swap. If I did not have about $15k worth of woodworking and construction projects lined up that I have to pay for (And do myself) this winter I probably would have already pulled the trigger lol. I would absolutely go this route vs spending $5k on a 100,000 mile used F series though.

Good K24's are still a hell of a lot cheaper than an F motor.

 

Good K series engines aren't cheap??

RBB K24's are cheap. $1000-1200, last I checked.

Even K20A type R longblocks are quite a bit less than a F longblock.

If I were in OP's position, I wouldn't trust a rebuild on a F series unless I found someone who know exactly how to build up a F series. There's so much non-standard stuff that people can't even trust the dealer in most instances. You have to find a S2000 specialist. And even then...there's doubt left on the table. Is it possible to have a succesful rebuild? Yes. Probable? No.

Yes, someone had to build them in the first place. But those someone's aren't just anyone. It was a handful of people who were building the engines by hand in a factory chamber. With all the support and equipment you can find at a Honda factory. They also weren't using parts from a previously blown up engine.


Here's a possible option, OP...

To answer your question about the ACT. There is no logical reason to use this unless you want extra holding power. If you're not going FI...then...go OEM for sure.

 

I'd have a hard time removing a perfectly functioning F but a N/A K24 S2000 seems pretty awesome. Used F series prices are pretty dumb. I do wonder how long the cheap K series will be available but that'd be a different topic. I believe the ones we want, with a separate header not cast into the head, have been discontinued for a while.

One option I do not think has been brought up yet would cost a lot of money but I think you'd have a reliable outcome. You could buy a new bare block from Honda and have InlinePro or a builder with extensive experience build it. It would cost a lot but if you want a new F series, that's the only option I see. A lot of the issues with F's seem to revolve around no solution to hone FRM cylinders. A new casting with new FRM cylinders would be starting from square one. I don't see why a good builder couldn't assemble a reliable engine from a new block. It's just that it would cost $$$ and require a lot of attention.

 

Considering they put Kseries in civics, crvs, multiple acura's, and others there are a TON of them out there. With how popular of a swap they are across a lot of cars not just hondas means there is a lot of support for the. 4piston is manufacturing new heads for them. I wouldn't be surprised to see blocks at some point (they do make billet ones but that's a different thing). If the F22 in mine ever went I'd go K series and buy a built one from 4pistion.

 

Yeah you're right, Type R K20C1's are going for less than F22's. If the swap kit is ~$5-6k a K20C1 swap may make sense.

 

SOS's K20C package looks pretty good. But...no, its like $20K or something. Still a good value for something that's mostly turn key tho.

RBB K24A's and K24A2's are super cheap though man. Millions of TSX's, Accords, and Odysseys got them. Honda just tossed a forged internal, 3 lobe VTEC engine into the most pedestrian cars for no reason.

The F series is a better engine in terms of build quality and durability. But the K series makes so much sense.

 

I thought the $20k is with a crate engine ~$10K, parts AND labor. If you do the labor yourself and get a used engine for $5-6k maybe it comes out to $12-14k. Considering a turbo kit costs around $8k out the door.
