Return of the EUNOS MANTICORE – featuring an Ecotec 2.4 engine swap

[MiataQuest]

will this be a stock version 2.4 EcoTech swap or Turbo'd? If its anything like the Mazda 2.3L it will have lots of low end torque!

Also looks like its brand new in that photo, is that a crate engine?

Yes, it is a brand new GM crate motor.
My plan is not to have a turbo. I am looking for simplicity/reliability while increasing performance close to the limits of the Miata drivetrain.
It will have a header, performance exhaust, and dyno tune.

I have rented a lot of N/A Ecotec powered cars for business trips over the years.
I was very impressed with the power/torque curve across the entire RPM range while still being a high revving engine. I believe it will really compliment the character of the Miata chassis.

I hope it can "do it all" with the 3.9 Torsen rear end and 5 speed.
* High speed, long distance highway cruising while using air conditioning.
* High speed!
* Keep it revved through the twisties for the ultimate Miata experience
* Autocross
* Occasional track day, pass a BRZ, keep up with better Miata drivers.

Today I got an update from Matt over at EcotecMiata.
The engine may be fired up tomorrow!
The completion date should be soon after that!
I am so excited

Now this is a sleigh ride!

The engine had it's initial start-up! Then the low mileage used transmission that I provided to them had a leak in the case halves. I had them split & re-seal the transmission. That was recently completed. It should now just about be ready for the dyno-tune. The preliminary schedule now is for completion sometime in early March depending on the weather.

Some other notes:
Ecotecmiata now offers an improved 4140 steel flywheel adapter with the latest kits.

Ecotecmiata is also working on a new kit that will utilize the Solstice AR5 transmission with the Miata PPF. This is good for higher horsepower applications such as running a Solstice GXP or Saturn Sky Redline turbo engine. A simple tune and exhaust nets over 300 horsepower. Also the turbo engine has a different flywheel bolt pattern. Going with the AR5 transmission allows for the original flywheel and clutch assembly to be used without any adapters.
