How much does it cost to LS swap a Miata?
We can't give a reliable figure for the swap-specific parts on a Miata LS swap yet: none of the required parts we list (mounts) has a price we've confirmed. The parts are below so you can price them; the whole-build budget is on the Miata swap guide.

The parts on our list for the Miata (2026 retail prices; required unless marked optional):
- V8 Roadsters MX5 NA/NB LSx Mounting Kit (engine plates, mounts, T56 crossmember) (price not confirmed)
On top of this you'll need the engine (junkyard or crate) and, unless a kit above includes them, the transmission, wiring/ECU and tune, fuel system, cooling and exhaust. The whole-build budget is on the Miata swap guide; price your own combination in the swap cost estimator and see how much an LS swap costs for typical ranges of each item.
