With the hardware portion nearly finished in the engine bay, the next step is to wire up the electronics. For this vehicle we’re using a MS2PNP that is set up for electronic boost control. Overall an incredibly easy to install unit, and the only wiring change (aside from the EBCS) is adding a post-turbo IAT sensor. This is easily spliced into the OEM harness, and with that we will have full timing and fuel control.

Well, not much of a rocket. In fact, it is a 1990 1.6 Miata that has been passed around more than….anyway. This car no doubt has a checkered past truly unknown, and surprised us with clear hints like a drag race strip sticker and signs of “put-back-togetherness,” that you only realize after pulling back the carpets. But that’s ok. Aside from having to trailer it from a neighborhood where 24″ dubs and tinted windows on Landrovers are the norm, the owner had duct taped the torn top together–poorly. As a result it released a torrent of rusty water when we loaded it up on the trailer. Not to worry, we have welders…
Day one, still on the trailer and ready to head to the shop.
Top has seen better days. As we pull back the carpet the drama unfolds.
Removing about 150 lbs of exhaust, wet moldy carpet, panels, top etc…
After pulling back most of the carpets, the body is surprisingly very straight and intact. Until….
…we get to the drivers side footwell. This one did not have the drain grommet open, so it collected water as the top leaked over the years. The result is some serious rust and hole in the floorpan. Nothing our welder can’t fix.
Current plan is to restore this car to a track worthy condition, and get it out to some local auto-x events. We’ll be gutting it as much as possible for maximum lightness, and adding in a custom roll bar setup. After that the fun starts!

We spent a few hours working with a customer on a JDL kit. First order of business is to see how our remote tune stacked up. We did the baseline run, then spent about an hour trying some additional variations to see if we could make any more power. Turns out the base tune with the remote revisions was spot on when mated to the wastegate spring.
What you don’t see on the dyno plot is that the boost controller the customer used was not functioning correctly, sending the car to nearly 20 psi. Fortunately our failsafe boost cut saved the motor. Upon arrival we were able to isolate the issue to the boost controller itself, and then did the dyno runs using wastegate pressure only. Despite only running 7 psi past 5000 RPM, we still made a healthy 277 WHP and 235 torque.
A customer wanted to get every last HP out of a car, and we of course are more than happy to do what it takes. While some of the intakes have a large MAF housing, they require pinching of the primary tube to get past the smaller OEM bulkhead, or reuse the OEM snorkel that necks down to 2.5″. None of those are valid options in our book. However, Skunk2 aka Kraftwerks/Grams/Group A, have released their intake which addresses many of those issues. Bigger snorkel, filter, and most importantly, a HUGE elbow from the filter to the TB. We put it on the dyno. Result? A bunch of HP throughout the powerband. A winner in our books! The BRZ/FR-S Skunk2 Powerbox tune is now available as well to remote customers.

The guys over at Hux Racing in Alabama installed and dyno’d a kit this week, and here are the results, over 300 on pump gas! This is all achieved on stock fueling and the stock pulley. Not only that, but this result is achieved with perfectly safe AFRs and without altering the knock control in any way.
Kraftwerks C38 BRZ/FR-S Kit, Tuned by Moto-East
A gem of an early Miata, this NA is quite unique. Panels that are straight, rockers that aren’t rusted, and the coveted 1.8 motor mated to an NA chassis. Only problem? Way too slow. Owner previously had a BRZ supercharger we put on, and pushed 285 to the wheels. Don’t worry though, we have a solution for slowness! 79 was dropped off last night to get some much needed boost.
What happens when a misrouted wastegate is employed? Normally fireworks and rods exiting the vehicle. However in our example here, the motor was saved. You can see a few things here. First off the timing goes way negative, and engine acceleration all but comes to a halt. The engine normally takes on a deeper growl and sounds miserable. That’s the cue that something isn’t right and it is time to double check things. Here when you look at the data, you can see that this BRZ tried to spike to 2.2 bar, that’s 18 PSI on the stock motor! Though some employ a fuel cut to aggressively shut the motor down, that can have its own consequences. That brief period ends up making the motor run lean and can cause a large detonation event when paired with high boost. Here we are basically not lighting off the spark until the rod and piston have started moving away. This creates a larger area for the combustion to happen, and greatly reduced cylinder pressures. End result? It gives you a second chance. This is just one of the things that makes our tunes stand out from the competition, and why we love the custom mapping ability we get with EcuTek RaceROM.

Here in the northeast things come to a halt in the winter. Lots of RWDs and drop tops enter hibernation, rarely to be seen until April or May.
For this winter, we are introducing the winter special. Instead of storing your car in the garage or storage, leave it with us to get some serious modification done! Custom roll bar/cage, custom turbo, supercharger install…all long(er) term project pricing will be 15% off from the months of November – March. But you have to book and schedule at least 6 weeks in advance, the earlier the better!
Having done several of these cars, we had a chance to get an otherwise 100% stock car with the Kraftwerks base kit on there. With 100% humidity and warm weather (and a broken weather station on the dyno so no corrections!) we managed over 260 WHP! Expect around 270-275 with correction.
Kraftwekrs BRZ/FR-S Dyno Results
100% totally stock original owner car with 80,000 miles, completely transformed with nothing more than a tune! We won’t get into the details of what exactly was done, but the timing is very reasonable, AFRs are safe and rich, and the turbo is not spinning itself into a blow dryer. Simply amazing with 305 ft/lbs of torque!
Did we mention it is equipped with EcuTek RaceROM? No lift shift, launch control, rev matching all enabled at the push of a button. Next up is ethanol testing and our new flex fuel kit.
