Awesome … or Sacrilegious! Meet the Nissan NX K24 Swap.

Paperwork, bills, other stuff just got shoved to the side when the Exedy HyperSingle arrived. It seriously looked like I was a standard transmission newbie when I went on my first parking lot drive. I’m used to it now, but this spins up so fast. The pedal is so light. Wow!

 

The Exedy HyperSingle combined with the K-Tuned 80mm throttle body and other upgrades makes for a car that is happy to rev!

 

There are many options for limited-slip differentials, and I turned to a company with a local connection. MFactory Competition Products makes a wide range of products that are race-tested and proven. The 1.5 Metal Plate LSD was pre-set by Patrick at MFactory for an aggressive bite – and that is absolutely the LSD that has been installed. I’m so pumped. Patrick also races at Mission Raceway, which is my home track here on the west coast, and he loves Honda’s way more than I do, so I cannot go wrong! After the rather clunky break-in period with 10w30 oil, this aggressive 1.5 metal plate LSD has significantly calmed down once filled with Motul Competition 75w140. Spoon magnetic drain plugs are also installed in the transmission housing and the oil pan – necessary security.

When ordering this MFactory Metal Plate LSD I requested that it be set at it’s most aggressive level. Before it was broken in, it provided quite the ride while doing the figure 8s. Now that the break in process is complete, it feels quite civilized. This is coming from a man who thinks that Kirkey aluminum race seats are very comfortable!

While the MFactory plate LSD was installed, AES Auto went over the RSX transmission to ensure that it was ready to go for years to come. The 05 Type S transmission has a close-ratio gearbox and a 4.764 final drive, which is an advantage on the track over the earlier model’s 4.389 final drive. While it was very tempting to take advantage of MFactory’s wide range of custom gears, here restraint was shown and the decision was made to utilize this transmission in stock gearing format. As I’m still running 15″ wheels – Volk TE37 and Gram Lights both of which were purchased at PZ Tuning – I want to see how this setup performs before doing anything extreme.

AES Auto specifically selected the RSX transmission with the 4.7 final drive. MFactory provides a wide range of gearing options – we left all of the ratios at factory specs. With the 15″ tires we are running, that should work well.

  1. 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.

    1. 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!

  2. 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.

    1. 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.

  3. 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.

  4. 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.

  5. 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.
