I would love to get my hands on one of the MZR-R engines. With Indy lights kicking the bucket, I wonder how long before they pop up?? Anyways.....

I've read that the 2.0L cams and heads on a 2.5L block was the way to go for max N/A power. I didn't know Indy Lights used the MZR, might be worth looking for cams and heads from those cars too...

Nah I just work here. LOL #shamelessplug

AFAIK Reverant has a PnP MS3 for NC in the works.

RalliartRsX 10-17-2018 03:11 PM

In my case, PNP is not the issue. Retaining emissions control via the stock ECU is.

nc's are not a popular platform to turbo, a few builds exist mostly on miata.net and most use fab9 tuning stuff.

As the prices drop, they will be.

The NC's are a way better platform to boost than our cars for the following reasons:

- 09+ comes with forged internals.
- Transmissions don't explode when you look at them
- Larger displacement engine makes for quicker spool and transient response
- Ability to flash stock ECU and have actual decent knock detection
- Strong diffs

Once they drop down in price even further I think they will replace the NA/NB as the "easy to turbo" Miata's.

The Enhanced MS3 for the NC has OBD-II support. :)

^ You have my attention :)

Doubtful. Unless MS wants an EPA raid and fines headed their way...

I dont think EPA has any reach in Greece

The EPA works in mysterious ways. If a third party is able to use a MS product to fool emissions readiness, EPA will place blame with MS for not locking the OBD-II protocol output down tightly enough.

Ask Edge. Ask Cobb. Ask Jeff Evans. Ask Bully Dog/SCT.

I'm trying to find the case of where a person or company was making a device specifically designed to shown emissions readiness (I think it was DSM's). Huge fines were levied on them when they were discovered.

BullyDog just got pinched.

Rolling coal and those damn brodozzers.........The dumbest thing this side of eating tide pods.

P.S EPA compliance cost $$$$. It an be done, but unless you have the deals in place (history of OEMs) and the $$$ to sink, then yeah....

Reverant 10-19-2018 02:25 AM

The key difference is that the Enhanced MS3 fully implements the OBD-II stack. This means that readiness monitors are only set if there are no pending or active DTCs, as the Enhanced MS3 supports about 60 different DTCs, much like the stock ECU.
