The PC-Pro gag was almost funny 2 years ago.

Lookin' forward to seeing pics of this kit! And your PNP AEM kit is silly affordable. Nice!

How many e-cool injectors tho...

I've seen the turbo, held the turbo, stroked the turbo. I still dream of the turbo.

What are you doing in order to put the Inconel/Stage8 hardware on the EFR? Will you machine the turbo housing or trim the hardware or what?

I was only able to fit the Stage8 bits on 3 of the studs and the 4th one had to be cut short. Otherwise turbo hit block stud.

We'll either trim the hardware or just use Resbond on that nut instead.

Cool vid on the EFR turbos:

:-/ I was hoping it was going to be a v-band kit. Decisions decisions.

There are no v-band options for the efr "yet". The general awesomeness of the efr and the badass internal wastegate/bov are definitely worth the 4 bolt hassle, especially when the inconel bolts have solved the "turbo fall off because racecar" problem.

Treadstone has had this page up for over a year now: http://www.treadstoneperformance.com...m.phtml?nik=52

but there hasn't been any recent news about those actually happening.

For a kit that is supposed to be hassle free and easy to install, the t2 4 bolt flange will be a one time annoyance. Also, depending on the manifold design, hopefully the turbo will be able to bolt to the manifold as one piece before bolting the manifold to the head.

^^ that and it seems it's mostly the Miata crew that has most issues with this. Somehow it seems others have managed to figure it out.

many other cars use bolts larger than m8 m10 IIRC. also lots more bracing since they come factory boosted. also lots less vibration since the bp vibrates like a dildo

Don't be ashamed, baby.

This kit will be bomb diggity. I don't want to hear people bitches about no 4 bolt flange neither. TSE's stud kits fixed that problem.

Of course, now I'm just waiting for the 1.6 kit to come out :rofl:

you should stop being gay and go 1.8 like the rest of the power bottoms on this forum

Nah

We will never do a 1.6 kit, sorry.

Bam. Cut off at the knees.

Good, then I can stay as one of the top HP 1.6L cars :).

Although, after seeing this MZR engine plot I imagine my next build will be a 2.5L VVT set up. Maybe with an EFR.

Savington - any reason you prefer the AEM ECU over others?

Lots of little reasons, but I'll hit on a couple of the big ones.

The AEMs are not the cheapest ECUs out there, but they are far from the most expensive, and they provide a fantastic set of features for the money spent. The EMS-4 in particular is one of the new Series 2 boxes, which gives it improved idle control and simply outstanding on-board knock detection capabilities. Not only does the ECU do its own window filtering, you can set a 2D RPM-based noise filter, and we can set a frequency filter in the software, all of which makes the knock sensor highly, highly accurate.

It's also got all of the features that you would expect a good standalone to have - electronic boost control, switchable fuel maps, excellent spark/ignition table resolution, and closed-loop WBO2 feedback. It also has native VVT control and OEM-style A/C control (TPS and RPM dependent), NB alternator control (with our patch harness), etc.

The AEMs are also very, very easy to use. This goes beyond the software (which is very good). The box has native USB support, so the maps download and upload fast, and there's never a struggle to select the right COM port - the AEM takes care of that automatically. The AEM software is based on tabs, and each tab combines several of the settings which you would normally adjust together. For new and intermediate users, there is a small explanation box in the right-hand corner that gives a brief synopsis of each function as you select it, which helps immensely with truly understanding the adjustments you're making. If you're an advanced user and you want to build your own tabs, AEMTuner makes that very easy - I've developed a tab on my tuning PC, for instance, that mimics the old VVT page from AEMPro so I can quickly make alterations to the VVT map. The software provides a fully customizable display of parameters with each screen as well.

For users who want nothing to do with the tuning aspect, the AEM is one of the most widely used standalones in the US across all makes and models. Even if your local dyno shop isn't a Miata expert, the chances are very, very good that someone employed there will be comfortable working with an AEM, and you'll get a great tune as a result.

Overall, the AEMs combine a great featureset, low cost, and the support of a very well-known and respected company. We've been using their ECUs for 2+ years now, and I have never wanted to upgrade or switch to anything else.

Thank you for the detailed response. When do you anticipate your kit being available?

No hard ETA. We'll post about major R&D steps, but we don't want to rush to market.
