Wondering when somebody will finally offer a turbo kit for the ND Mazda MX-5? Wonder no more, because that time is now. Flyin' Miata is now selling BBR Stage 1 turbo kits for the latest Miata, with claimed power increases of 70 horsepower and 70 ft.-lbs. from a kit that would look factory to the untrained eye.

Per Flyin' Miata's site, each kit includes:

• BBR bespoke twin scroll hybrid TSX30-71R turbocharger including jet turbine specification fixings
• BBR bespoke cast iron twin scroll exhaust manifold
• BBR stainless steel downpipe
• BBR high-flow lightweight front mounted aluminium intercooler with factory look black intake pipes
• BBR high-flow custom silicone turbo pipes in factory look black finish with stainless steel hose clamps and unique black coating
• BBR lightweight aluminium battery tray in factory black finish
• BBR Recirculating piston type dump valve in factory black finish
• BBR / Bosch MAP / Temperature sensor
• BBR high efficiency carbon fibre turbocharger heat shield
• BBR high flow K&N Typhoon induction kit
• BBR stainless steel oil and water lines
• BBR Starchip EcuTek RaceRom calibration software

The kits cost $5695 each, and Flyin' Miata claims they're the easiest kit to install that they've ever produced.

Everything looks good on paper, but what's a turbocharged ND like in real life? Look for an exclusive first drive report right here at Grassroots Motorsports tomorrow.

Funny you brought this up. I saw one being delivered yesterday.

With the reported issues with the ND transmissions, isn't this just adding fuel to the fire?

What is "jet turbine specification fixings?"

The transmission was upgraded in late 2016. If you have an early one, you have 3 years/36000 miles to break it.

I believe BBR is sourcing aerospace spec hardware.

I must have missed that they upgraded the transmissions.

I love OEM looking upgrades- not a hint of silicone blue . Looks like very short routing and with the latest in turbos I wonder how little the lag.

I like that the ND is the first miata quick enough out of the box that a turbo version could more or less automatically be assumed to be fast. In the past, a bolt-on boost kit for a miata wasn't even guaranteed to make it as fast as an ND is stock.

Buh? It's been a long time since anyone sold a turbo kit that didn't make at least 150 rwhp on an NA/NB.

It's not all about the peak power number, NDs are faster than the power peak would have you think. It's a legit comment. Think about the state of the Sebring supercharger circa 1991.

Basically no lag. The high compression spools this thing quick. I'll bet that if we didn't have the big TURBO on the hood of our car, you wouldn't guess it was turbocharged when you drove it. It's quiet.

A) a Sebring isn't a turbo and B) As much as it makes me feel old to say it, 1991 counts as "a long time ago". :)

Do you have a dyno overlay of an ND vs, say, a Voodoo2 on an NA/NB?

Keith Tanner MegaDork

Vigo also used the term "bolt on boost kit", which I think also includes SC. From the 30,000' view, the evolution of forced induction for the NA looks like the evolution of forced induction for the NC. The ND is shaping up to be slightly different, possibly, but some of the same factors are still there such as an initial supercharger kit that will be limited but a commodity.

I do not have that comparison readily handy, but it's kind of irrelevant because they're very different cars. The most powerful Voodoo is going to have slightly less peak power than the initial dyno runs for the ND turbo, and the ND will only get better from here. The shape of the curves would show a bunch more low end with the ND due to the higher compression and larger displacement.

Vigo brought up the question of a turbo NA/NB vs stock ND, which is what I was addressing. Yes, with the extra displacement/etc I would fully expect an all-else-equal turbo ND to be faster than a turbo NA/NB.

In reply to Keith Tanner:

Just curious, how much weight is gained from the turbo kit? I'm assuming around 50-70 lbs; that about right?

I'm sure you guys have been pushing it. Any idea what a boosted ND would need to survive ~20 minute lapping sessions? Bigger radiator? Oil cooler?

In reply to roninsoldier83:

70lbs on that car could be made up easily in horsepower. Hell, most Americans could lose 35lbs and make their miata faster

Keith Tanner MegaDork

It's not 70 lbs. I don't have weights yet, but I'd say closer to 45. The box isn't all that big

More information on cooling, etc to come. Most of this car's time has been spent either on the dyno or in the trailer going to the Mitty!

In reply to yupididit:

I wasn't thinking so much in terms of weight as I was weight distribution. When I drove the 124 Spider Abarth, I could really feel the extra 100 lbs over the nose vs the ND. ND felt much more eager to rotate.

In terms of acceleration, I'm sure a boosted ND is a riot to drive!

April 22, 2017 10:36 p.m.

In reply to Keith Tanner:

Thanks Keith! I'll eager to see what you guys learn and put together for the boosted ND!

Nice looking kit Keith! I am sure you will move plenty of those.
