286whp 205wtq N/A K24 build
Here's a nice K24 build we recently put together. It was running on a basemap and wasn't fully sorted out until we got it on the dyno yesterday, and it proved to be a winning combo. The idea here is to show off what can be done with your typical K24A2 powered Miata if you're looking to take it to the next level.
The chassis is my blue 2000 NB, weighing 2180 lbs. with our K24 Ultimate Swap package. No changes were made to the swap kit parts list, it's all the same stuff on our website. Skunk2 Ultra Street manifold (no porting), 74mm throttle body, KMiata 4-2-1 race header. 3" intake, 3" exhaust. Engine setup is as follows: Stock K24 block Wiseco 12.5:1 pistons (87.5x99mm) K1 rods Stock K20A2 head (RSX Type S). No porting Drag Cartel 4 cams Supertech valve springs 775cc FIC injectors Tuned on pump e85 (tested at 78% ethanol) As you can see, this combo rocks out to 9000 rpm with a torque curve that can barely even be called a curve. We plan on throwing a 4Piston ported head and ported manifold into the mix soon which should put us comfortably over the magic 300whp mark. Can't wait to get this thing back on track in the spring. edit: It's worth noting that this was done through a ZF 5-speed trans, Getrag stage 2 diff, and on 15x10s with 245s. https://cimg3.ibsrv.net/gimg/www.mia...297d247719.jpg https://cimg0.ibsrv.net/gimg/www.mia...3eaa8e95f3.jpg |
Looking good so far! Curious how mine is going to compare with a slightly different but less extensive approach. Will also try to get dyno plots for science.

Very good David. Assuming no local access to E85, any estimate on how that combo would perform on 91 octane pump gas? I suspect 12.5:1 Pistons would be a tad much for our Calif. piss water gas. What ECU did you use? That is not a torque curve, but a torque table. Kudos! |

Kudos! 12.5:1 pistons would be fine for 91 octane, you'd just have to pull timing but I'd still expect this setup to make 270s on 91. This car is running Hondata Kpro. |
