We just finished up the first stage of project s2K24 and I thought I would share the progress up to this point. Our goal was to do this swap utilizing as many of the stock f20 and k24 parts as possible so others could do this without spending alot on custom manifolds, rails, fittings ......... For this project we started with a 2006 Acura TSX k24a we picked up for $1500 and proceeded to make an adaptor plate for K engine to F trans as well as an intake manifold adaptor so the stock s2000 intake mani could also be utilized. This aloud us to use all the stock fuel lines, rail, sensors and so on cutting down on cost. We also found a mix of stock f20/k24 pulleys and tensioner so no additional custom hardware is needed there ether. So far it is only fuel tuned with no dyno time or cam angle tuning but even with that I can say this is the engine Honda should have put in this car to begin with. The stock f20 was gutless below vtec in this heavy of a car. But now with a 2.4L and vtec coming on at 3500rpm this car is a much more pleasant daily driver. You have good useable power from about 2800rpm and up. With the stock K cams it is only making power to 7800 rpm or so but with some Skunk2 cams (closer it size to the stock f20 cams) it will soon be back to making power well over 8000rpm. Even though it doesn't make power to 9000rpm anymore the powerband it's self is MUCH wider than it was with the f20 equaling a much more usable powerband. All through the stock s2000 intake, header, cat, and exhaust. We will soon have dyno numbers and I will post them up when we do. After that comes stage 2 of this build we will be adding a PTE6265 so stay tuned!! Enjoy












**update 5-16-11**
we finally got time to put the car on the dyno for some cam angle and ignition timing tuning. This sheet is a comparison of a stock AP2 tuned on Hondata with intake and exhaust vs the sk24 with intake and exhaust. The AP2 made 220hp and the s2K24 made 219hp but the real story is told under the peak. The s2K24 is making about 40tq and 35hp more around 5500rpm than the 2.2L AP2 engine. AP2 was tuned on 93oct vs 89oct on the S2K24. The s2K24s engine setup is: stock 06 TSX K24a2 bottom end, stock K20a2 head with TSX ex cam and 08 Si intake cam with 50* vct gear, stock AP1 intake manifold and TB, and a stock AP1 header. Next we will being adding Sunk2 cams and maybe a TB. We will post those results when we get time, then the turbo kit goes on so stay tuned!!!

 

Sweet build, anymore details or pics?

 

sweet another k series swap!!! have any plans of mass producing this as a kit??

 

looks good... I just replaced my built motor with a 2006 K24a2 it is a great motor cant beat oem reliability

How did you deal with the upper coolant neck on the back of the head I cant see anything in your pics?

 

what is used to make the K24a ecm and sensors work with the S gauges??

 

thats pretty awesome! I love how everything bolts up! Nice work!

 

What's the difference in hp and tq

 

Are these adapters going to be sold in the future? It would make the swap tempting.

 

Awesome swap! With the way ivtec is coming....... this might be the best option.

 

Thanks guys. We swapped the TSX head out for a k20a2 head that doesn't have the rear water port that would hit the firewall. Since we made an adaptor plate to be able to use the f20 intake mani we are able to use the water port on the back of the stock mani. We do lots of different K swaps but this was by far the most challenging and fun K swap yet
