KMiata recently debuted their K24Z3 swap kit for the Mazda Miata. The company already offers kits for the K20A and K24A engines however they received a lot of feedback from customers wanting a kit for the K24Z3 model. The K24Z3’s biggest drawback is the integrated exhaust manifold however the benefits are lower price, availability, enough-for-me power (205-210 whp), and being able to use the stock Miata subframe. The initial price of the kit is $4295 and includes engine mounts and pads, transmission adapter, flywheel and dust cover, baffled aluminum oil pan, oil pump adapter, hydraulic clutch release bearing, Wilwood master cylinder kit, RWD intake manifold, 74 mm throttle body, wiring harness, upper coolant neck, serpentine belt, billet aluminum timing chain cover for K24A crank sensor, and 3-inch downpipe. You can read more details on the kit here.
Is this for the NA chassis also? Or have the NAs gone forgotten and not worthy of mods anymore?? Remember the NA is what started the whole facination and craze in the first place. I have 94 Miata with just over 67000 odd miles, and a 2017 Fiat which is the closest thing to the original Miata as you can get, especially when you remove the VERY heavy factory muffler and replace with non resonated popular axel back exhaust which removes at least another 20 lbs. I do love the original 1.6 I’d just love to do simple webber carb conversion, or small turbo like the new Fiat 124s. Cant even tell there is turbo, no lag etc. Always loved how smooth the 1.6 was compared to the 1.8 from the Protege and 323. The 1.4 on the Fiat doesnt idle particularly smoothly however lots of software which will raise your btm line by a good 30-40 hp with few mods if any.
Yes. This kit is built for the NA and NB models.
I have had 6 NAs, 2 1.6s the rest the 1.8. A turbo on a 1.6 sounds sweet. Or once I educate myself on these new Skyactive motors I will likely be impressed. Anyone know if there is a conversion for the Fiat 124? To go to the newer more powerful and higher redline naturally asperated Mazda Skyactive? Gas miliage has to be better than the Fiats 1.4 as I average 25 mpg overall. Not si impressive when that’s what a 92 1.6 would give you or better. Like 31 mph on highway. Mixed driving was about 23-25 mpg
What do these skyactives see miliage wise? Redline is 7.5 or higher? (Need to read up)
NA and NB Miatas are mechanically 90% the same.
