Transform your Mazda MX5 into a performance powerhouse with our cutting-edge turbo conversion kit. Unleash untapped potential and experience a thrilling ride with enhanced horsepower and torque. Engineered for precision and reliability, these kits are the ultimate upgrade for every enthusiast. Embrace the thrill of the track and conquer the road.

We have created the ultimate Mazda MX-5 Turbocharger DIY Kit. Using the very best CFD Cast Manifold, Genuine TD-Core Turbochargers, M-Tech 3-piece intercooler systems, and, of course, the ME442 or ME221 ECU. This is a complete turbo kit to transform your MX5 into a turbocharged 250BHP machine (with the addition of a clutch and further tuning!).

Why use our kit?

We have been working alongside M-Tech in tuning and developing their drive-in/drive-out turbo conversions since 2014. This means we are using the very same components they have used, tried, tested, and proven over and over again in over 300 conversions carried out to date. This means above all else, reliability. When installed & tuned correctly, there should be no extra requirements when using your car beyond annual servicing – giving peace of mind for tens of thousands of miles.

Our bolt-on complete kits will allow you to realise around 180-250bhp (stock clutch permitting). With a clutch upgrade (along with mapping) you can safely run up to 250bhp on stock engine internals. Go for a TD05 turbo and a forged engine, and 330+bhp is easily in sight with lower spool than the larger Garrett Units.

With UK offices and full-time support staff at the other end of the phone, we can help you get your cars up and running on the pre-installed basemaps – we even include a startup check over a remote connection should you need it, getting you ready for a visit to your local rolling road for a final polish of the map.

The kit consists of a few main components, to see a full breakdown, see the bottom of this listing;

Manifold and downpipe - We utilise the G19 EVO2 Cast Manifold in our kits, proven to flow better than competitors, meaning more power and less engine stress. Couple that with our unique, in-house designed 2.5″ CNC Mandrel bent downpipes means an accurate, trouble-free fitment, with improved flow over monocular hand-fabricated units. Our downpipes are also fully TIG welded for longevity, and use a quality flexi for years of happy boosting.

Turbocharger - Our manifold, downpipe, and intercooler kits are designed to work with the IHI TD04-Pattern turbocharger (as fitted to UK model Subaru Impreza's), and as a result, we stock genuine units. They also arrive pre-clocked, meaning everything will line up once bolted on – not like the Garrett Models competitors use which may require custom fabrication for a good fit. They can deliver up to around 280bhp with ease and, being a modern turbo, they spool early giving OEM feel and driveability.

Fuel Injectors - For fuelling, we use genuine Bosch EV14 Injectors. Complete with MX-5 specific inserts and plug adulators means a painless install. With over 640cc/min fuel flow rate, these injectors are good for up to around 350bhp, yet still deliver a steady idle and excellent fuel atomisation.

Engine Management - Of course, we use the Plug-In ME221 ECU as part of our kits. The premier ECU for the MX-5, as used and recommended by all the top tuners in the UK. Fitting the factory casing makes the installation a doddle, and we are always on hand if you need support. We pre-load a suitable basemap so your car will start and run, ready for you to arrange tuning at your nearest rolling road. The ECU's powerful feature-set can be used as your project expands, offering advanced strategies such as closed-loop boost control, anti-lag, and launch control. For motorsport-orientated builds, we recommend upgrading to the ME442 for the onboard wideband and added engine protection strategies.

Fasteners and fittings - Everything is provided, from the basic nuts and bolts, jubilee clips, and water lines through to the custom braided steel oil supply hose, Inconel exhaust studs, turbo gaskets, and Mikalor clamps – its all there for a pain-free install from start to finish. Also, every part of the kit is labeled to help you identify what you need as you progress through the printed install guide.

Manual - Our 30-page, printed install guide covers the full process from stripping the stock parts, fitting the new parts, stage-by-stage checks and finally getting the car running. Also, included with our complete kits, is a 30-minute TeamViewer session (if needed) whereby we can dial into your laptop and carry out a remote sign-off of the ECUs settings, and sensors and help you with the first start. Also, at any point in the build, we are on hand, 9am to 5pm on Weekdays with dedicated UK phone support.
