Nice. I suppose a twitter of this wouldn't have quite as many updates as a normal twitter. Nonetheless it's good to hear the rotary is running.

By your estimation, would it be possible to run this swap with a normal RX-8 ECU? I know Hansamobile in Germany is supposedly doing that. The reason I ask is I need any swap to pass CARB, which means factory ECU and all the factory smog equipment.

 

I'm currently running a Racing Beat modified RX8 ECU. 09 RX8 parts would be quite interesting for this swap as well.

Tabasco is Spicey!!!

 

Oh. I thought you were running a piggyback. Good to hear that you're running a stock RX-8 ECU (relatively).

Wouldn't the 09 be relatively similar? I know there's all that third injector jazz and all, but they swap over too wouldn't that? Considering the improvements to both the 09 NC and the 09 RX-8, this would be an interesting thing indeed.

 

nice sound it made

 

hehe, "my wiring genius"

I guess interfacing the mx-5 stuffsz with the rx-8 ecu was a fun superwire solderpalooza, but I need to be able to make it more 100%'d. I don't even think the tach was working

 

ahh is it blue like the one in japan

 

The tach works fine.

Paul.

 

oh, i should've figured you pansyfoots wouldn't rev the thing... I couldn't tell in the video if the tach was working or not, it didn't move much except for the start-up sweep thing...

 

My dear son (And talented wiring GENIUS), instead of making your big chested internet statements , why don't you come down here and see it in person and BE in the next video.

Paul.

 

hehe, I didn't realize my chest had gotten big enough that even the internet noticed! I'd like to come see it run in person, hopefully sometime this week.

 

As usual I look forward to seeing you.

Paul.

 

Was the K-frame changed on the 09 RX-8? If that is still the same, the engine should still bolt up right? Even better, it goes with the transmission it was already designed for, the NC transmission.

 

Same K frame as previous. What I'm suggesting is an 09 engine actually. The NC tranny is not the same but rather family just as the original RX8 trans was derived from the Aisin 6 speed from the NB Miata. The NC 6 speed I took out is built by Mazda and yet when I installed the RX8 Aisin gearbox it fit perfectly with the shifter arriving exactly where it should and the driveshaft splines from the Miata are identical. Two different manufacturers and identical dimensions (Or close enough).

Paul.

 

Well I'll agree to that. With the improvements to the 09 engine, it would be a no brainer to try to incorporate it if you have access.

 

this is such a sweet project---you have to see it to appreciate it.
2500lb car with the renasis engine. Huge amount of room in the engine bay. Once the connectors are completly done heck a swap package could be sold. i would consider it.
this engine looks like it was made for this car

I'm hoping that Mazda releases a rotory driveline option for the MX-5. I think if it was rotory only, it would kill alot of the current popularity and wreck havoc with the various series it is used in. But I agree as well. The 13b and the MX-5 go together way too perfectly to ignore. It wouldn't surprise me if they were supposed to be produced together at some point in time, and money, economics, or politics got in the way.

Danny's detailed build in Australia is a prime example.

I'll be watching this build as well!

 

Any updates on this project? It's been a few months and I think a few of us want to know how it's going.

Also, do you happen to know how much the NC's MZR engine weighs? It seems there's no data point on that. It would be interesting to know just to try to calculate a rough delta on the weight change with this swap.
