1990–2005 Mazda Miata NA/NB LS swap with V8 Roadsters mounting kit: engine plates, polyurethane mounts, DOM-tube T56 crossmember with 3 exhaust-routing options; retains factory suspension/steering pickup points (V8R).
Recommended engine: Any LS (LS2 + T56 per review); LQ4 works but needs intake, accessories and crank pulley changed to suit the chassis (V8R) — compare LS engines & donors
