The scope of this project was and is immense. It isn’t something that I will do again (at least, not in the near future) but I commend AES Auto for working with me, encouraging the swap, and then bringing all of the pieces to fruition. In the past, I’ve always had my hands all over the projects but for this one, due to the pandemic and the intensity of the build, I handed the keys to Paulo at AES Auto and he and Taylor took off! While putting the K24 into a Nissan B13 platform was new territory, AES Auto is a Honda specialist and have done numerous swaps into a wide range of vehicles. Most recently was a K swap into a Honda Fit – a meticulous project that I’ve followed from the beginning (and have to write about soon!). AES Auto has looked after my car since I moved to the west coast almost 6 years ago – and I’ve appreciated the creativity, ingenuity, and dedication that this shop offers. There was no question in my mind about who should lead this project – it was AES Auto. My role was relegated to securing some of the parts and being a cheerleader. Due to the pandemic, I wasn’t even able to take my own photos so huge thanks to Sean and Ronald for looking after the build photos for me.
Honestly, the engine was the easy part. Paulo had a backup K24a2 out of a TSX that was pristine – and he no longer required it as a backup engine for his 1000 whp AWD Civic – so that was an easy choice for the powerplant of the NX. There’s a lot of talk and evidence of the advantage of a K20 head on this block, but we stayed with the K24 head. AES Auto assured me that set up properly, this head would perform as well as a K20 head. This engine was mated to a 05 RSX Type S 6-speed transmission.
This setup was left stock …
Haha ha, yeah right! There was simply no way that a stock K24 was going into my NX1600. In fact, the only reason a stock K20/24 was in the engine bay was to allow AES Auto time to mock-up engine mounts. And then the work began.
First up was a Unit 2 Fabrication metal oil pan. This steel pan is going to be excellent for the power levels and track use that the NX will be doing. The Unit 2 Fabrication K Series Elite aluminum oil pan is absolutely astounding, and if my budget was unlimited then it would absolutely be on the NX. However, the K-Series Steel baffled oil pan comes with a 4 compartment baffle system with 7 trap doors. James Houghton runs this same pan in his very fast GLTC Acura TSX. It will be ideal for my use. Unit 2 Fabrication is a Canadian company that I’m very proud to support and represent.
