Don't you hate it when you're texting and girl and her reply is " k "
 

We're at it again! We acquired a wrecked car with a good front end and electronics system so that we can do a K swap from start to finish!

We are working on the following:

K Swap Plug and Play Wiring Kits
K Swap Mounts
K Swap Oil Pans
K Swap Transmission Options
K Swap Headers
K Swap Hose Kits
K Swap Intake

I will try to keep a detailed list of what we have spent parts wise on this swap as we go!

Parts Purchased Used:

K24 With 120k Miles $900
S2000 6 speed with 90k miles $600

Parts Purchased New:
K to S2K adapter kit $900
Skunk 2 Intake Manifold $770
6 Puck ACT Clutch $500
DBW Throttle Body $380

I'll keep it updated as we go!

Update Video!

Final Resting Place! Our prototype engine and trans mounts are just about finished!

Why the S2K Trans? How does NO CUTTING, NO HAMMERING, NO WELDING sound????

Oh fuck yesss was losing hope for a sec LOL. Are we wble to find out what ecu we be using? Also will you be making a turbo manifold for the guys that want to boost?

$4k into it so far n looking good.

Yes!!! :party0030:
Looking forward to do this swap

I had a RSX type-s back 2 years ago before buying the FRS, alway liked the K20Z1 way more then the Fa20... This kind of swap is an option I will consider most likely!
Keep up the good job guys!

When are the mount availible for purchase?

OMG FINALLY!!! I love this. every. single. bit.

I prefer it when they text back "JK LS". JK. Cool project!

So, HASport says a K24 with axles, manifolds, accessories and transmission weighs 413lbs. Subtract the transmission, axles and p/s pump weight from the listed K motor weight and you're looking at an easy 100 pound reduction up front of the 86 compared to the FA20. Maybe more depending on manifolds used, etc. That's almost more appealing than the power bump.

What is this insanity? A Hondubaru? Subhonda?

Interested to see how this works out! Always liked the K24!

Is there still room for heater core hoses to connect?

Does front of motor sit any further back than stock motor?

No height clearance issues? Assume this is fixed by oil pan you referenced?

Also will you be doing a full dressed weight so as we can comapre to fa20 motor trans weight? Would imagine there is a a 60-80lb weight difference (which would be awesome)

more room for heater core hoses then the LS or 2J swap actually. Need throw a hood on this car (shell didn't come with one) to get some pics, But it clears with a straight edge and the tallest point is further back than the tallest point of the 2J swap so it should be no problem. The modified oil pan is to set the motor back to clear the subframe and steering rack more than height. It is as low as it can get without cutting the subframe

We are almost done getting the design 100%, after that, we take them to our water jet guy and wait for them to cut a complete run of them, then we weld them up and powder coat them, so probably 3-4 weeks hopefully. I hate waiting on other people lol

I spoke to another shop that did a one off K swap in a rocket bunny FRS, theirs was turbo and it still only weighed 2460 full interior! So imagine no turbo kit and no rb kit, I think with some lightweight wheels and brakes you're talking 2300ish, that is INSANE if it happens.

Love the idea of this so was wondering how one would comply with emissions etc .

Also which is the best model K24 engine to use if one was to do a swap as I know next to bugger all about Honda's :sigh:

Which adapter did you use that cost $900. The only one im seeing is the Ballade Motorsports one for $400.

Wow...sub-2500 would be fantastic. Free horsepower and handling.

Are you planning on doing any internal engine work? I'm not too familiar with Hondas but stock power levels aren't particularly impressive on the k24 unless I am missing something?

massive NA potential. 300whp is a cake walk for them. That plus less weight off front end will be amazing. at 2400 lbs thats a 8:1 weight to power ratio. Rough equivalent to a 400whp sti or wrx for comparison.

that's just the adapter. You need the custom flywheel as well

For this particular setup, no, but if I were doing it for myself, I would probably do cams, springs, retainers at a minimum.... and then boost the crap out of it lol

250+bhp in a sub 2500 pound car doesn't sound like fun to you?

What would one have to do to get 300 NA? 250-280 with head work doesn't seem unreasonable for a 2.4L, but I'm a bit surprised at 300. I guess on e85 it wouldn't be unreasonable if that's what you are talking about?

A bit off topic, I apologize.

Unless I missed something in my limited research, stock k24s made like 205hp at the crank...

Im not familiar enough with Honda motors to speak from authority, but what has been discussed in other threads is the difference in having reliable, power potential over the Fa20.

good simple breakdown

Is it safe to start buying the parts on your list that you bought new?

You're correct - I saw the S2000 transmission being used and started mixing F and K motor spec. My bad. That said, it still isn't a bad platform to start with, and the weight reduction is still very real.

Lol I figured that was what was going on. I was thinking the same thing until I looked it up too.

I agree it's a great platform to start from if you eventually plan to do head work. In addition to weight reduction, it also looks to shift the cg rightwards and rearwards, which is good for LHD versions of the twins. Only problem with this setup is moving the cg up vertically by some amount. Low cg was the main benefit of the boxer IMO. (I don't think Subaru knows how to make anything else anyway, so that is probably just an excuse lol).

True, but it's a higher cg for a lighter motor, and further rearward. Accessories are also lower, so if I had to guess, I'd say it's a wash.

Lol @ all the people who are worried about the k motor... This is the best swap since the 2j or ls...

A friend sent this to me... Enjoy.

How much will the entire swap package cost approximately? 5k like your LS and 2JZ packages?

What ECU will be used?

Any other options besides pricey Motec??

Would it be possible for Pure to collab with the K-Miata guys for an A/C kit for this swap??

Why not use the 5 speed bmw trans that are being used in Miatas?

This swap has my happy. If my FA blows, this is a possibility. My friends EK mad 240whp on e85 with a K24, and all "oem" honda parts inside. No aftermarket cams,and a meh header.

the s2k trans seems to be the cheapest route and is fine for what most people would do. Maybe if we get a build or this build turns into a boosted application we can make more options available. At this point just trying to get it up and running for the most reasonable price that it can. From there, the possibilities are endless.

we are working on a new way to drive the ecu cost down. there's still a fair amount of r&d that needs to be done but it is in progress starting with our current 2j vvti car. once that's sorted out, the same setup will be adapted to the K/F20 setup

Guessing issues are linked with getting all the interior stuff figured out. Could get cheaper if it was a full race car with no oem stuff to worry about?

Ive debated selling my brz limited, cause its a heavy pig and making a race car out of a wrecked or stolen car.

Did this guy just openly say he'd use a stolen car? :bonk:

Maybe use a aem infinity? Like what prime did

Nothing oem works. If none of the oem features work, we don't want to use it. AEM and Haltech had no desire to work with us and we have been asking them for well over two years at this point so their loss. We are playing with another ecu that is very capable, but at this point we still have a lot to do software wise.
