MX5 NC Alternator Relocation Kit

When Mazda Forgot Turbo Kits Exist

Let’s talk about the NC’s engine bay layout for a second. Mazda put the alternator on the exhaust side, which is fine if you’re planning to keep everything stock forever and maybe add a sticker or two. But the moment you want to fit an actual turbo setup? A downpipe that flows properly? Anything larger than a hairdryer with ambitions?

Yeah, that alternator becomes your nemesis.

It sits there, hogging prime real estate exactly where your turbo manifold wants to live, and suddenly you’re playing 3D Tetris with metal objects that get very hot and don’t compress. Spoiler: you lose that game every time.

What This Kit Actually Does

Simple: we move the alternator from the exhaust side to the inlet side of the engine bay.

Suddenly you’ve got room to breathe (well, your turbo does). No more sacrificing downpipe sizing because “it won’t fit past the alternator.” No more creative routing that requires a degree in origami and the patience of a saint. Just proper, sensible space to build what you actually want to build.

Plus your engine bay looks cleaner. Not that you bought an MX5 to stare at the engine bay, but it’s a nice bonus.

What You Get

• Alternator relocation bracket (the bit that makes this whole thing possible)
• All necessary hardware to mount it properly
• Instructions that assume you know which end of a spanner to hold

Important: This kit is for NON-AC cars only. If you’ve got air conditioning, this isn’t going to work without significant modification (and at that point, you’re on your own).

Alternator Compatibility (aka “the ones that actually work”)

You’ll need the 3-pin type, which slots straight into the MX5 NC like it was meant to be.

• Mazda 3: A3TJ1091 (110A)
• Mazda 6: A3TG1391A (90A)

Note for LHD owners: You may need to trim a little metal off the alternator to clear the steering arm. Think of it as giving it a quick haircut — not a full lobotomy.

Why You Need This

If you’re going turbo: This isn’t optional, it’s essential. Unless you enjoy explaining to your mates why your turbo manifold looks like a modern art installation and your downpipe has more bends than a politician’s promise.

If you’re staying NA: You probably don’t need this. Save your money for other things. We’re not here to sell you stuff you don’t need.

If you’re thinking about going turbo: Do it now. Seriously. It’s ten times easier to relocate the alternator when the engine bay is still relatively stock than when you’re waist-deep in a turbo install, realizing you should’ve done this six months ago.

The Bottom Line

This kit frees up exhaust-side space so you can actually build your NC properly instead of compromising on every turbo-related decision because Mazda didn’t think anyone would want more than 160bhp.

It’s not the sexy mod. It won’t make your car faster. But it makes everything else possible.

And sometimes that’s what actually matters.
