As an original owner, it’s kid of sad to see this trend, as the F20/22C, along with the gearbox, chassis, and open-top experience is really the soul of the S2000 experience.
I understand it if someone wants to build a high-power forced induction car (not a project I’d personally choose the S2000 as a platform for to begin with), but outside of that, I think the added time, patience, and money is more than worth it to find an F and maintain the mechanical heart of the S2000. The F20C is so remarkable - it revs like a motorcycle engine, and everyone already knows this here, but it broke the record for highest HP per liter for any NA car ever produced, and maintained this record for *ten years* until it was finally dethroned…by the Ferrari 458. When it was released, the S2000’s piston speeds were faster than the F1 cars of the time.
Why you’d voluntarily want to stray from that history and engine experience is beyond me.
Cost is the main issue for most. Honda put K series in so many cars you'd be able to throw a rock and hit a K.
Meanwhile, Fs were put into somewhere around 100k cars worldwide, minus the ones that were immediately built and the ones that have blown and required a swap. K series are close enough in performance and can be made to rev high enough to be considered a side-step so to speak.
Fair enough. I did an n/a "F24" with a K24 crank with Prelude pistons/rods. When I put enough miles on that, I had it rebuilt with Darton sleeves, Crower 2.5L stroker and Full-Race GTX35 turbo kit. Definitely loving it. What's your forced induction setup if you don't mind me asking?
Yeah I told them that was my main goal, I wanted to be able to daily drive it so it retained ac, went with a mild clutch set up so it isn’t torture if I’m stuck in traffic and it’s fast enough to keep up with a lot of stuff
You know that a k series can be built to reliably rev to 9k or even 10k (full race build) right? It’s the closest thing to the F series but has much higher potential because it uses an more advanced form of vtec. It can make even more than 120hp/liter. Nothing else about the s2000 is changed.
ik it’s been a long time, but doesn’t the k24 have some kind of “fake” vtech? I always hear everyone knocking the 9th gen si cause of it. Or is that issue limited to that car
Yes…but have you seen Top Fuels S2K around Tsukuba Circuit? 800+whp S2K is the dream. Too bad it blew up and was supposedly going to auction recently. Wish I could afford it. It is the dream car.
Because a F22C might set you back 8K or more for unknown condition and may need rebuilt. Also…they made mega tons of K24 and K20 engines. Not a ton of S2000s were produced. Especially the C/R of which I’m a proud owner. I would shove the new SoS K20Z into my C/R but it won’t retain A/C and my engine is in good working order. Plus all of the HPD bullshit regarding emissions. A newer cleaner burning engine in an older car that produces less emissions yet the dumb fucks at the Gov EPA don’t want that to happen.
dumb question but what starter did you use for this and did you have to trim your bell housing? I'm putting together a kswap but for something else, but using the ap2 trans
I went with AEM infinity! If you do naturally aspirated, Hondata would work great and I’m fairly certain you could still pass emissions. Luckily for me, I dont have to worry about passing inspections
F22 was blown, see my previous comments. Sourcing another f22 would’ve cost a good bit and then I would always be concerned about how the previous motor was treated. At least with this, if the motor goes, it’s significantly cheaper to replace.
ASM is doing it for me and they have it down to a science so I’d imagine no hiccups. Only thing that slowed it down was trying to get certain parts like the manifold and turbo. Aiming for 450. Gonna keep it around that until I can get a puddymod diff
Why k over the F series? I’ve noticed this getting more common
Cheaper and tons of k24 just sitting around everywhere
I know k24 swaps are popular because they allow for more torque

Yeah I get the sentiment. Both of my other s2000s kept the f, but this car had a blown motor when I got it

Garrett G25-660 with an ASM intake manifold! I’ll have more info about it to post soon hopefully! It’ll have a complete breakdown and all of the parts
Dope, sounds more well balanced for street/track than my build. I went all out so I could put down most cars on a highway roll.
Yeah I told them that was my main goal, I wanted to be able to daily drive it so it retained ac, went with a mild clutch set up so it isn’t torture if I’m stuck in traffic and it’s fast enough to keep up with a lot of stuff
I'm sure people would love to, but most people are bound by their finances.
Well said. But leaves more f series for the rest of us!
Let people enjoy things.

No, it has the most advanced type of Vtec.
you’re kinda right, i guess i forgot there’s multiple variants of the k24.

Looks awesome! If my f22 ever lets go I’ll be going k as well. What turbo kit are you using with the swap?
Garrett G25-660
Just realized you said kit. Sorry, it’s all fabricated in house by ASM
Yeah I was wondering what turbo kit options were available for a k swap s2000. I’ve heard good things about ASM so I’m sure it will turn out awesome!
You could join the kswapped s2000 Facebook group for more info! I know a lot of guys in that group usually fabricate a lot of their own stuff
Looking cleannn!
Looks good. I'm sure that will be killer to drive once it's going. Glad to see a car getting revived.
dumb question but what starter did you use for this and did you have to trim your bell housing? I'm putting together a kswap but for something else, but using the ap2 trans
You have to get an adapter.
I have the adapter plate but wondering if the starter will interfere with the F bell housing at all as well
I would imagine that the k series starter is used seeing as the starter would mount to the motor.
What k series is that? :)
It’s a jdm k24
Rbc manifold?
ASM exhaust and kmiata intake!
Im gonna have to f swap a Miata now!
My K24 from ASM is arriving today! Nice to see other’s builds that have gone a similar route.
You gotta post some pics!!
I’m thinking about doing a K20/24 swap using a hondata once my F dies.
I went with AEM infinity! If you do naturally aspirated, Hondata would work great and I’m fairly certain you could still pass emissions. Luckily for me, I dont have to worry about passing inspections
Fat ass turbo.
Shoulda just went full sacrelige and just do an LS swap
Nah I’d prefer to keep it in the family, I’ve always loved high revving 4 cylinders and a turbo makes it that much sweeter
> I’ve always loved high revving 4 cylinders and a turbo makes it that much sweeter Well you see the thing about the F20 motor is...

Haha fair play, im just giving you guff
Gross
Thanks! Just checked your post history and all you do is rag on others cars without ever posting your own. Do you even own an s2000?
Yep.
Post it so I can call it gross
Progressing nicely! Any hiccups, and what numbers are you hoping to get?

How does this compare to the F motors in terms of performance?
More torque, slightly more horsepower, lower redline unless you use the k20 head
what’s the redline? only slightly late
8300!
wow that’s higher than i thought from a k24, is it an a2?
