Build Summary

This list equips you for full DIY maintenance and repair on your 2005 Mazda Miata NB with the BP-Z3 1.8L engine. The NB Miata is a well-documented, wrench-friendly platform, but its low ground clearance demands a low-profile jack. At advanced skill level, this kit covers oil changes, brakes, suspension, spark plugs, valve adjustments, and diagnostic work within your $1000 budget.

Vehicle Intelligence

2005 Mazda Miata — BP-Z3 1.8L Inline-4

The NB Miata has a timing belt (not chain) due at 60k-mile intervals — a critical service requiring a rental harmonic balancer puller. Valve clearances must be checked with feeler gauges every 30k miles: intake 0.25mm, exhaust 0.30mm cold.
