Mazda Miata NB (1999-2005 US model years): Power mods

Forced induction and engine swaps Reported

R&T and a mod guide say turbo and supercharger kits are common; the Mazdaspeed's non-VVT head and lower redline limit big power; buying someone else's finished build is cheaper; and the clutch needs upgrading at higher power.

Caveats: No kit is recommended here; no power figures are verified.
