TD04 Turbo Kit for Mazda MX-5 NA NB

Our TD1 kit is the ultimate TD04 turbo kit including absolutely everything you need for your engine to make 250 horsepower. With years of personal experience with each product, we have handpicked the best and most effective parts specifically for the TD04 platform. We’re confident you won’t be able to find a more complete kit anywhere else.

At the heart of the kit is the G19 cast manifold from Motorsport Electronics – one of the best TD04 manifolds currently available on the market – coupled with a high-quality pre-clocked TD04-13T turbocharger. This includes an accompanying downpipe that fits directly to the catalytic converter.

You have the choice between the ME221, ME442 and MS3 Mini ECUs. The ME221 and MS3 Mini will come with AEMs X series wideband sensor and controller whereas the ME442 comes with its very own plug and play wideband sensor and onboard controller for the easiest install.

The TD1 kit also includes often overlooked extras such as a dedicated boost control solenoid, Forge blow-off valve and tap & drill bit for the oil drain.

Years before BOFI, our very first turbo MX-5s were cobbled together TD04 builds with questionable parts – this is the kit we wished we had back then and we’re sure it’ll put a smile on any MX-5 owners face.

We Can Install This For You

We've designed our workshop services to be easy to book and pay for online. To book, you'll need to pick a date and time that suits you and then add the products you want to be installed.

Each workshop product is a labour price only. We've recommended some products on each page, but you can also find other compatible products at the bottom of the page. This way, you know exactly what product you're getting and how much its costing to fit.

Add both the workshop service as well as the product to be installed to your basket and proceed to the checkout. Once there, you can confirm your dates and process the order. Occasionally, some products may require confirmation, when this happens we will make sure we have the stock to fulfil the install and get back to you within 1 working day.

If you have any questions, want a bespoke installation or would prefer to book over the phone, give us a call on +44 (0) 203 795 0515 or send us an email at [email protected]
