Project S2k24
**4-4-11** 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.

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!!!

round 2 of project S2k24. This time we have added Skunk2 stage 2 cams and a Skunk2 74mm TB thanks to my buddy Tony Shagday at Skunk2 Racing. Skunk2 has come through for us time and time again over the years with great support and products. I really cant say enough about this company and the team at Skunk2!! I also must give a shout out to Justin at FullBlown as well for providing a FB340 fuel pump and radiator as they have for some of our other s2k builds. We are still using a stock K24a2 bottom end and unported head, OEM s2000 header, and modified OEM s2K intake manifold,.... for now. 170tq off the throttle at 2500 rpm makes these cars way more fun to drive. No more down shift to pass people and it still makes power to about 8400 making for a much wider power band than the old f20c ever thought of.

** update 1-31-12 **
we just started on round 3 of this project, boost time!! We are in the process of fabbing up a turbo kit right now and should be finished soon. We are hoping to hit 500hp with only 12-13psi. Kit consists of a 6265, id2000s, tial 44mm gate, tial BOV, 2.5"-3" IC Piping, and custom manifold. Updates coming soon so stay tuned!!
