If you’re thinking about jumping into a project like this, then by all means go for it. But this is not a project that I would consider again. Should you go out and attempt this swap – probably not. But it is a project that I am happy to have. The creative powerhouse behind this unique build is absolutely AES Auto. Paulo, you are the man! Taylor, thank you for the skill and focus you brought to the table. If a creative swap is your dream, then by all means, go for it! Want a great team to work with, AES Auto is my first choice. Meantime, stay tuned for the next update that be a review of the Feal Suspension and the NX K24’s first trip out to the track. A quick spoiler – while there were a few minor glitches I was smiling all day long and the NX K24 was one of the last cars to come off of the track at the end of the day.
Huge thanks to the many enablers who have encouraged me on this journey. James Houghton, Jeremy Norquay, Bron Palko, Kyle Krunick, and Ronald Retandy. And there are so many more.
Were you worried that I’d end without numbers – that simply cannot be. I cannot leave you hanging without providing these critical details. We all know that dyno numbers are relative, but in 2018 on this same dyno the 54C turbo put out 359 wheel horsepower. In 2021 with the newly installed K24 the NX was back on AES Auto’s Mustang dyno where it developed 281.6 whp and 215.2 ft/lbs of torque from this naturally aspirated build. 200 whp is attained at about 5000 RPM and just before 5000 RPM 200 ft/lbs of torque is hit and that continutes through to about 7500 RPM. At this RPM the intake manifold’s limitations at upper RPM probably took 10 to 20 whp away. Although it’ll likely take more than a cut and ported RBC intake to hit the 300 whp mark. The question is, will I leave the RBC intake as is, or won’t I!

you really love that car…
I’ve owned it since it came off the showroom floor – so the answer is yes.
DAMN VERY NICE. IS THERE A SWAP KIT FOR SELL ON THIS K20 INTO B13 SHELL. IM SURE ALOT PEOPLE WILL BE INTERESTED SINCE THERE SO MANY PARTS OUT THERE FOR THESE K20 MOTORS.
B13NX2K, there is no kit that I am aware of in production. Sorry.
The Ridge Motorsports Park is in “Shelton, WA”, not “Sheldon, WA”
Noch, thank you for catching that. That slipped past all of us! In the first paragraph, no less. Corrected!
Very good read on the article Frank. Enjoy the ride.
Upgraded, thank you so much. You’re very aware of the struggle that I’ve had the last few years. And know that a lot of thought went into this decision. Thanks so much for introducing me to AES Auto!
Awesome write-up Frank! Cool to see such an unorthodox (turbo to NA) swap play out in such a satisfying manner.
This K24 engine is simply silly fast. WHP drop from 360 to 280 – but at the first track day I was out all day and as long as I wanted each session with temps barely rising. I haven’t had a day like that with the DET ever.
It’s like Honda put the things it learned in the past into the K24 and made available in many platforms — Decent power, good reliability with potential for upgrades.
Awesome Build, Awesome write up! Thanks for sharing
Brycen, glad you enjoyed the article. I’m enjoying the car. It’ll be back at the track in a week.
I don’t think we got a final pic of the subframe, but it seemed like there had to be more crossbracing than the one bar with the motor mounted in it, right?
Also, that’s a 4-2-1 header that’s installed.
Hey, congrats on the build. It should be bulletproof.
That’s it for bracing, Joe! And bulletproof is the key here!
A little sad to see the SR go, but nothing better than having a track car that just works every time and nothing to think about! 280whp on a mustang is plenty of power. It would probably trap 115-120mph in the 1/4.
And for reference, my old B14 SE-R with T25 and JWT S3 cams put down 250whp on a dynoject and trapped 110mph. The poor stock VSLD wore out which made the car about worthless on an auto-x. Not too bad on a road course with big enough turns to keep from lighting up the inside tire.
Khiem, sorry that I missed your posts. I haven’t had it out to the 1/4 yet as I’m worried about the axles. I’ve lost Nissan axles in the 1/4 and they were relatively available so I wasn’t worried. These axles are one off and, while I’m having a second set built, I don’t want to risk them just yet. The M-Factory LSD is absolutely keeping the power down in corners, so I’ll have to get out to an autocross (just never been my forte), and just a few weeks ago I put down a personal best at my local track. Besting the SR20DET’s time by half a second.
Man I have a Nissan 200sx. I would love to do a K-swap in my car.
Hi Thomas, there’s now talk on the SR20 FB groups of a swap kit. Maybe it’s getting closer!
Cool to see someone throwing a K series in an NX.
I currently have the only known Nissan Pulsar NX with a K series.
Well Done! I think there are now more than one B13 chassis with the K series, but at the time this was the first running one that I knew about. Do you have some pics of yours?
Sacrilegious! what acrap of project, this articule must be remove and banned from this great webside
I would like to know the list of items I need to swap a k20 and k24 swap into my nx2000
Frank Ewald
Would it be possible for you to send me the parts list that I would need to put in a K 20 or a K 24 in my Nissan NX 2000 and what would be the best mount to buy to hook the motor to the B 13 body for the K 20 or K 24 motor mounts
I’m trying to figure out what universal harness indeed for my nx2000for nthe inside of the car.
what harness did you use for your nx2000 kswap
