My initial tune I had done with Steve at Divulge Motorsports turned out to be a massive disaster. After some extended time driving and having taken the car to the track, I noticed the car didn't seem 100% and was no where near the claimed 250whp. It's a long story, and I will note the details possibly later if I can be bothered to, but I ended up having to file for a chargeback that ended up being successful which I was quite surprised I had won in all honesty. I ended up going with Jeff Evans at Evans Tuning which I highly recommend (He also tuned a buddy's supercharged s2000 which I was doing the datalogging and revisions for). My final numbers for the car ended up being disappointing at 204 peak hp & 159 peak torque.
If I had been on a stock k24 motor I would have been perfectly happy. However, I had opted for some camshafts which were supposed to have netted me ~220 peak hp & ~170 peak torque. After speaking with a few friends and other k-swap folks, the conclusion was that the engine was limited on how much air it could flow. The cable-throttle s2000 OEM throttle body is only ~62mm and the K&N FIPK intake tubing is largely similar in diameter. At the time, I was also running a 63mm test pipe into a 70mm exhaust system. I looked into finding options on expanding the oem intake manifold, and even had a fabrication shop looking to do the work. Long story short (again) it didn't work out and in anger/desperation I purchased a brand new K Power Industries RWD intake manifold.The KPI intake manifold is a direct fit for K-series engines. This meant I ended up having to need to replace my fueling system with RDX injectors, new fuel rail, new fuel pressure regulator, and other various fuel fittings to be compatible. I also upgraded to a 74mm throttle body and fabricated a matching sized intake. On the exhaust side, I opted for a 70mm test pipe and a 76mm catback exhaust.
After explaining to Jeff that I would be doing some upgrades, we worked on more revisions to account for the breather mods. As of writing this update, Jeff sent me a very polished revision and he felt confident that I would be good to hit the dyno and get my required dyno certification runs.
Final results, and the configuration I will be running for the rest of the year, are 218 peak WHP & 169 FT/LBS of torque. This is much more in line with the expected power bump from the cams!
This update wont be nearly as polished as the initial post but I had just enough motivation to recall and write down my thoughts of the last few months. All in all, it was a fun journey building the car. I do miss the 9k redline of the old f20. But for the purposes of the car, the k24 just cannot be beat in terms of usable power & cost effectiveness.
Hey @jiepo I went the ASM route, current working on spotting a small oil leak. If you have any questions HMU. Working on getting my butt into HC eventually currently in HPDE2. I continue to run VIR Full to get more comfortable with the build, summit will be on the books for next year I think if not by year end.

Thank you!
Im actually expected to receive my GLTC spec motor with a Link ECU and PnP harness from ASM later this week. Nice to see there's so many others doing similar swaps.
Hey @jiepo feel free to DM me with your location. I kinda networked with other s2k folks to really gather my research on who I wanted to perform the swap. Part of me wanted to tackle it myself, and well it really boiled down to time vs. money. I have an AEM Infin 506, Andy has moved on with LinkECU, I know it was an option for me to swing either Haltech or AEM, link wasn't available yet. Andy is a wizard when it comes to these cars period, but I do think there are several areas where I would focus. My (very small) loss is your gain here. I have NO clue what your plans are for your S, but there does seem to be more Kswaps and/or new-er s2k track builds. My local fabricator told me such. If you wanted a pointer to a good fab again just let me know.
Make sure you ask about getting a breather on your valve cover out to a catch can, when I received mine it was quite literally "breathing" (more like coughing) onto the FW, without a filter or anything like that.
I ended up removing the OEM pressed part and putting in a swivel radium unit which works just fine. I can provide you the part number if you wanted
Killswitch (good band but srsly may want to consider his wiring expertise)?
I had swapped in AP2 drivetrain including trans, diff and to the hubs. (Not a fault of ASM nor Andy but.....) I would have them shake it down a bit either on video as proof or something akin to that.
Check valve cover for leaks, I have one (again not faulting ASM nor Andy here) but I will be refreshing the VC gasket with some optional HB in specific areas of note (any pointers from the audience would be great here links welcome)
Check the drainplug on your moroso pan, the copper washer provided wasn't the right spec and leaks a drop here and there, check it before taking delivery.
Make note of the additional oil you will need to feed the car
I added an oil cooler to mine cause I invest a good amount of coin in refreshing the block prior to "sending it" to Andy. @robrob gets the nod here great writeup and frankly I owe him a beer or five (coffee if else)
I would ask Andy where he plans on mounting the ECU, mine is where the OEM location is, a bit tight, but I kinda wish I had it mounted someplace else for easy access.
I am slowly working on generating more content for my youtube chan, my goal is eventually to get to Honda Challenge with NASA.
Thanks for all the pointers, I just checked out some of your videos!
I'm in Canada and planning to do all the work myself. I've already begun disassembling my car.
I believe I'm the first to get the Link setup.
I've got a vent-to-atmosphere catch can ready for both the PCV and breather ports. Unfortunately looking at the pictures I got, I think I got the valve cover without the removable press fitting. The radium press-fitting would've cleaned it up a bit.
Ahh hailing from the North. I should ask for some good ol Tim Horton's coffee, good stuff. I used to work for a Canadian Telecom company back in the day. You are performing the swap yourself?
I am doing just about everything, I really needed ASM's expertise on swapping in the trans, motor, drivelines, hubs etc. You'll have to share some of the goodies o the link setup, is there a mobile app to view things, license fees etc?
