blueprint's K24 Powered S2000
 

First and foremost i'd like to thank Alex, Matt, Aaron and crew over at Ballade Sports for making this happen for me.

Back in March of this year I spoke with Alex and decided on doing a K24a2 swap for my AP1. The Potential, Availability and Cost of the K series really appealed to me and made the decision easy. After mapping out what this swap entails we put everything to paper and went to business.

Overall the entire build exceeded my expectations. I wanted to keep the build as simple as possible and in the end I believe we accomplished that. As far as where we go from here that's still up in the air.

Very cool!!! Any plans for forced induction?

There's a part of me that would take this over your GT4. Congratulations :thumbup:

Don't get me wrong, this is a beautiful build but why not just stroke the f20 with a k24 crank? You would get the same numbers at a fraction of the cost...

Nice. I was thinking of doing the same in the future since I've had K-swapped vehicles in the past. Checking how much the swap kit cost? Also does anyone know if we're able to use our current F series SC setup for the K?

Looks good! But a couple of questions:
- why keep the OEM intake and intake manifold if it´s known to be a limitation to the F engine so with the increased displacement of the k24 would be worse?
- torque shouldn´t be showing more improvement since it´s what makes the K series "famous"?


also the car looks lovely!
keep us posted with the project :)

Usually my problem every morning... Which car to take to work lol.

In all seriousness the K24 S2000 would give my GT4 a good run.

Zero. Im not a fan of Forced Induction.

Finding another F series + machine work + parts + EMS... It was a wash when we added up the costs. In the end we achieved something different. The Cost, Engine availability and overall potential was the driving force for making this happen. Im not knocking the F2XC... It's a phenomenal engine but the numbers speak for themselves.

The swap kit was a little north of $3k.

Not sure about the F series SC setup... I highly doubt it would work though.

I considered it but was curious to see how she would do with the F series IM/TB. I also prefer the cleaner, OEM look. The numbers aren't to shabby either.

It looks like the tuner was very conservative with the cam timing to say the least. Your typical K series will have a nice fat hump in the middle from the cam timing. I tuned a similar engine with 11:1 compression ratio pistons and cams a few years ago.

Notice the hump in the middle and the peak torque coming in around 6k.

Here's another example:

Mmmm Power! K24 8400RPM All Motor Dyno !!! - Club RSX Message Board

That's a stock block k24a2 with the same brian crower stage 2 cams. Again, notice the hump you see on your typical K series.

You should be seeing a lot more mid range hp.

I don't think cost for performance gained was the primary goal here, or he would have just bolted in a stage 1 Supercharger.

Nice. This is a project I want to tackle down the road. For the reasons you listed and mainly because I'm looking for a big project. Do you plan on seeing any track time with this car?

People get really upset over this engine swap for some reason. :confused:

Do you have AC?

yes he does

My tuner very well could be erring on the side of caution... It's hard to gauge how other K24a2's perform when there isn't much information out there on one swapped into an S2000.

Yeah, it does look like its starving for something about 5k rpm. The power kicks pretty good still about 5700rpm so I don't know if its just a matter of ignition timing and fuel, or cam timing/transition, but your clearly leaving free power on the table.

thats encouraging. I'll discuss with him and see where we can improve.

I'll be joining in this spring.

-08 k24a2 bottom end
-type s head
-ballade header
-custom RBC mani w/ 74mm TB
-rdx injectors
-3.5" cold air intake
and maybe some BC stg 2 depending on what my tuner says

Very nice!! Look forward to seeing your build.

thanks for sharing. i'm looking to complete mine hopefully this time next year.

ciuld you elaborate on the pulleys and belt used? is ps/ac remaining?

looks amazing! Glad to see anther Swapped S2000 with something other than the small stroke F.

Curious on how you only spent "a little north of 3k"

Seeing as I spent a "a little north of 30 k. LOL (the kind of LOL that hurts)

LOL 30K is alot!

Pretty sure Allens 3k is for conversion parts only ..not built motor, labor, ECU etc.

Hehe just to clarify i said the "SWAP KIT" itself was north of $3k. I can't disclose how much exactly i spent as I was given a very good deal on the swap.

The engine, head and parts alone were well over $8k.

It's amazing how fast this stuff adds up. My first motor I think I had it in the car running for like $6500 (more like $2k after selling OEM F22 stuff) but it only made just north of 240whp. So, then the power bug bit me, By the time you buy $1000 intake manifold and $2000 ASP header, dry sump, different cams, Different engine mounts etc etc etc then loose a motor, then a 2nd motor the bill starts to tally pretty high. I'm afraid to add mine up, but I'm fairly certain I'd be north of 30k, Maybe even approaching the over the hill number. But I've probably made about 30% of that back selling the take off parts. So it's not as bad as it looks. I at one point had a $1000 bill from a dyno shop for the car having a tuning issue (turned out to be cams) that sat on the dyno for an entire day doing random pulls.

I agree. I was able to sell off my F20c1 stuff to recoup some of the costs but the parts for this swap added up very quickly. I had initially thought about doing a F series stroker utilizing the CNC kit however when I added up the costs it was looking to be in the $7-9k range as well after all was said and done. Figured for a little bit more I can swap the K series in and have much more potential in the process. The aftermarket support for the K series is huge and the cost/availability of K series engines made the swap very appealing.

It was not cheap but in the end Im very happy with my decision to swap the K in.

The other advantage is you can sell the F stuff and it then makes the K cheaper.

I have been keeping a spreadsheet of my build so I can post up an actual cost for one of these swaps soon. I am hoping to be running by the first day of spring.

2017 OR 2018? Just kidding. I wish you the best of luck.

Dressed it up a bit.

Changes are coming soon. :)

is the stock heat shield still able to bolt to the car behind the header?

Nope.

Just curious, whats the main reason behind this swap? Sure you might make 30 tq over a f22 in the midrange but with peak numbers being damn near identical i dont feel its worth $15-20k on this swap unless theres something else real obvious that im not seeing. I mean kudos to you for getting the swap done but wheres the big benefit?

Unless I'm reading the dyno wrong it's showing 251hp to the wheels, which is quite a bit more than a F22.

Except the OP isn't making a killing in the mid range here either. It looks to be making pretty much a stock vtec F series power curve, just a bit more power throughout. About 20trq/whp over a Standard bolt on F22. Not to knock all the hard work here, but yeah I'm pretty much in the why bother camp myself. But I have always been thrifty with my money with this car, trying to get the most for the least. This build flies in the face of that in every way. To each their own as they say.

okay maybe i was exaggerating a little when i said damn near identical lol. But 30whp and 30wtq is not worth $15-20k imo. Plus all the research and work put into doing the swap unless he just dropped it off at a shop and paid someone to do it.
im just saying there are means to gain just as much with the stock platform for far less. But if he did it just for the sake of having a k series in the s2000 then my curiosity ends right there.

I always wondered how these would do supercharged as in root style. Heck, just get your basic k swap kit and a stock k24 and supercharge it. Should make a shit ton of mid range without building the motor.

kswap kit as stated above-3k
k24 long block-1k give or take
root style supercharger jackson/comptech-2k?

Another positive is the supercharger will keep the perfect balance compared to a Sos/vortech f series supercharger. Blow the motor? No problem, grab another stock k24

Mod for mod the K series just offers so much more potential in NA form. Additionally the K series has i-VTEC which allows a variable intake/exhaust valve overlap.

This configurability allows the engine to respond to modification much better. To greatly simplify it, it allows the engine to make both high top end power and low end torque by varying the amount of valve overlap based on RPM & Load.

In the end the decision for me was simple. The potential, engine availability, cost of replacement engines and the endless aftermarket support. They all played key factors in my decision to swap this engine in. I am very happy with how the car performs.

Smaller cams solve that. A lot of the "stage 3" cams out there make less power on the K24's till 8000. Sure they make a bunch more power from 8000 up. But A sub 8k motor needs a much smaller cam then what he's running and that allows you to run more VTC which will give you a much bigger Mid range bump in power. I myself have made the same mistake and put much smaller cams in it recently. Haven't made it to the dyno yet.

I'm one of the few people that can appreciate the swap. That being said, I'm curious to know if the current setup is set to extract the most amount of reliable power from the k24 or is it a mild setup? Is there a possibility to squeeze out more power from this engine than what you have already shown us?

Similar setup with aftermarket intake manifold and E85
https://cimg4.ibsrv.net/gimg/www.s2k...16acc6258f.jpg

E85 is next for me. How much WHP do you think E85 got you? 10....20WHP?

It was 2 different motors, but this motor was better then the old motor in nearly every way and made 6hp more and the old motor was on race gas.

damn..only 6. Ok maybe not next on the list lol. Cams and Intake mani hunt for me still I guess

Not to mention all the E85 headaches you gain. (where to buy the stuff, is it really E85, now you gotta test it. Or buy the flex fuel sensor. My Haltech isn't setup for one so I have to buy the sensor, an I/O expander and a Can Hub box. $1000ish later and the thing still cant test for Moisture in the fuel).

I had a budget in mind when we put this together and more importantly I wanted the swap to look clean... If i didn't care about AC and Power Steering I very easily could've gained even more power.

I have a pretty simple build. It has a head built by Portflow which has full Supertech valvetrain as well as Porting but other than that it has bolt ons. Stage 2 Cams.

-Drop In Pistons.
-Stock Air Box
-F Series Intake Manifold
-91 Octane

I very well could just remove AC, Upgrade the Intake Manifold and run a less restrictive intake and probably gain 7-10hp with proper tuning. Im leaving power on the table however with my current tune as I believe the car is capable of a little bit more... Im doing homework currently and going to have the car re-tuned at some point.

Well said, It's not worth the extra headache.

he made 6hp over his old motor which was on race gas. He probably made 15-25 over a pump gas setup. E85 or bust! 280hp n/a is nuts

Correct but the old motor was 1.7pts less compression so I don't think the E85 gains were much.

Beautiful car.

I run 100 octane now 13:1 compression. Never use 91

My previous engine was 12:1 and was tuned on 100 (kinda old 100 actually). This engine is 13.7:1 and was tuned on E85.

I had an 06 TSX moderately modded in addition to my CR. The TSX engine was very responsive to any mods. Nice pic on the swap. Nothing you say will convince me that your S is as quick as the GT4. Unless I can get a ride of course. :)

Hey mate, what have you done with the breather port on the valve cover? The last pic on page 3 shows it left with no hose/filter.

I am thinking of capping this off/welding it closed, and tapped a new fitting on the opposite side so its closer to the rad.

sorry to bump an old thread .. i am about to do this swap and wanted some insight. no one really explains the harness issue. what engine harness was used, what needed to be extended and what sensors added. i know the rywire was used. what ecu ?

thanks op

what did you do to make the ac to work

Wealth of information here guys, thanks!

I heard through the social media grapevine that this engine blew in a canyon run. Is that true? Kinda disappointing.

how much did that put down? We did 293 whp on a stock k24 bottom with a stock port and valve k20 head with a mild cam and an after market intake mani. Motor had a real fat mid range. Alternatively, a stock off the boat k24 did 249whp. With an aftermarket header and intake manifold. All tuned on 91 octane.

how much did the conversion and parts cost?
