One of my other projects...K24 Miata Swap :)

[aCab]

A few friends and I are swapping a K24 into my 10th Anniversary NB Miata. Initial goal is 230whp/190tq.

I have been laying low on the forum for the past few months, but I have some exciting news for the K series and Miata communities.

With the help of a few close friends, we are building what we believe to be the first K swapped Miata. Best of all, once we have it up and running (summer of 2013) and have some seat time on track, I plan to make all essential swap parts available for purchase. It's putting the cart before the horse a bit, but just wanted to let everyone know that this is not just a one-off swap, but one I hope can be easily duplicated by fellow racers.

As a K24 integra track car owner, as well as a Miata owner, this swap just needed to happen. Honda reliability, and a 2000 lb. RWD chassis with legendary handling is going to make the perfect track car, or even daily driver.

Best of all, we expect this swap to cost us less than most popular K swaps into the EG, EK, and DC2 chassis, as we are using the stock Miata trans (5 or 6 speed), stock rear diff with Torsen LSD, stock shifter, driveshaft, radiator, axles, etc. As you can see from the pics, the miata has TONS of room for this motor. Although we are mocking this all up with a cheapo k24a1 motor, the eventual plan is a 230+ whp 190 wtq k24a2 setup. Stock bottom end, just some cams and dual valve springs (maybe even use the stock TSX cams). We will be using an S2000 manifold with an adapter plate, which should be ready to install in the next week or so. Clutchmasters is supplying me with a custom flywheel that will allow any Miata clutch kit to be used.

Biggest part of the project is the crossmember mod, which is still in process but will be done this week. While this first car will have a chopped, tubed, and welded stock piece, we plan to do the next car with a full tubular crossmember similar to the V8 swap kits. Next car we do should be a bolt on swap with no welding needed.

I feel this swap has some distinct advantages to other Miata power upgrades. I feel it is a better choice that a turbo setup because we will make more power out of a mildly modified K series build, and it will keep things cool and reliable on track. V8 swaps are cool, but less practical for road racing, they add 200 lbs., and require much more modification and parts that our project. V8 swaps require welding, custom driveshaft, new rear end, axles, and the list goes on. Finally, f20c and f22c swaps have been done, but as we all know, a k24 has much more all motor potential than these motors, it has VTC, and more aftermarket support. Plus using the stock Miata trans simplifies the swap and keeps cost down.

Anyway, enough talk, here are pics of our first few hours of the swap. The goal is to shake this car down at Gingerman Raceway by the end of May 2013. Stay tuned

too sweet

Cool!
After turbocharging a 10th anniversary NB I fell in love with them. So easy to work on...

Good luck with the rest of your build!

Very cool. Surprised that K series into Miata hadn't been done before.

Hoping to debut this car at ITR Expo in September!

I like it.

Quick question: Why put a K24 in a Miata as opposed to an AP1/AP2? Just curious.

Still, very cool swap.

i'm guessing the reason is it's a lot lighter and cheaper to do the swap in..

nice job OP

Wow!

Unfortunately, things change. I am moving from Chicago to Atlanta and have decided to relinquish this project to my friend that was working on it with me. It's a great swap, but for the time being, I could not find a use for it in my stable or my budget .
