I'd love that.... lightweight sexy 2 seater 2 door with the new engine mmmmmm

I meant to stick a worked S6/RD engine in the RX8.
Just waiting for RGs response .It shouldn't be too much a drama . Some of the parts would be interchangeable , balance wouldn't be compromised ,my question is will the interceptor work ,would the throttle body be able to fit and be utilised or would you use the cable .Uhhhhh Any more problems ?

mikeschaefer

yea i got my threads mixed up, oops!

guitarjunkie28

everything should fit LOL
i'm in the process of a cosmo swap in an rx8 right now. the fd tranny is easy to molest into place, but everything else has to be done from scratch. it's a LOT of work!

Ciao

I have been of entertaining this option as well .How do you sync up the Speedo with the FD tranny ?That was my only fear .I would much prefer the S6 Box
Also besides fabricationg new engine mounts ,should the rest be straight forward ?
The alternator,etc should just mount up ??Maybe one could utilise the front cover of the RX8 engine to fascilitate in the crossover

How about the Management ?Can you run the Fly by wire throttle and run the intercepter as per "normal"as per what Rotary God Says?
How are you going in the transplant guitar junkie? The 13B cosmo is almaost identicle to the S6 engine

I am looking at doing this conversion .......more power....Mmmmm 500 at the bags

the swap is holding still until the customer gets more money, but the engine and tranny are mounted up, ready for the turbo and ems to be installed.

So I should be able to disconnect the factory ecu from the coils/injectors/water & air temps sensors but leave everything else connected including the crank angle sensor (I assume its needed for the factory tacho?).

Then I hook up the Microtech to the coils/injectors/water & air temp sensors and piggy back on to the crankangle sensor. I probably don't need the tps as I'll be tuning in MAP mode and the engine will idle fine in the load map.

Does this sound about right?


I also thought about fitting an FD engine and 5 speed. Off the top of my head some mods would be:

Mount the engine & box
Change to cable throttle
Remove the RX8 ign coils
Adapt speedo sensor into FD box (or the FD one may work)
Lengthen drive shaft?
Modify sump?

Leave the stock ecu connected to all of the sensors. Leave the mass air flow sensor in place. Leave the ignition pickup trigger alone. All you do is tap into the lines you need to with the Microtech while also only disconnecting the wires you need to from the stock ecu. Many wires such as oil and water temp sensors will be hooked up to both ecu's at the same time. You disconnect the injectors and coils from the stock ecu. That's it. Leave the rest in place to it and keep it working. Then just tap into where you need to with the Mictrotech. The stock ecu still needs to controls certain other things.

That sounds straight foward. Is there a reason why I cant remove the mass air flow sensor? It would make the piping a lot easier.

seriously mang... just talk to scott at mazsport. he's the man.

rotarygod

Theoretically you could but the factory ecu still needs to read from it to do certain other things. That's why it stays put. Remember it's still controlling the drive by wire! Yes it works. The maf isn't a restriction anyways.

The only thing that may set you back is if the Mictrotech can't read the stock ignition pickup wheel. It might not. The Interceptor while based on a Microtech can read it. I don't believe the standard Microtech can though. It might just be easier to use an Interceptor. The wiring issues are all worked out for you and it can read the trigger wheel.

You always come through RG !!Legend

Look who's back!

Thanks to you ,Sir
