BMSwaps.co.nz was built around one obsession: putting BMW’s incredible inline-six diesel engines into the vehicles that deserve them most.

I’m Turoa, based in Auckland. I got into BMW diesel conversions because I genuinely believe the M57 and N57 are two of the best engines ever made — and most people have no idea they exist. Smooth, torquey, fuel-efficient, and built to last. They just happen to come in BMWs. We fix that.

Every build gets the same treatment: proper engineering, clean wiring, and a result that drives like it was always meant to be that way. No bodging, no shortcuts. If it’s leaving the workshop, it’s done right.

Based in Auckland, I work with customers across New Zealand. Not local? Get in touch — we’ll work out what’s possible.
