NB Miata project – Performance modifications after six months

In my last post I covered my experiences looking for and purchasing my current project car, an NB Miata. I also covered preventative maintenance work to get the car up to a known reliable state so that I could move forward with other mods and really enjoying the car.

This post covers NB Miata performance mods that I have done to my car during the first six months of ownership. I explain what I did, why I did it, and what my experiences were with various different mods.

Full exhaust system

When I first got my Miata it had an engine code related to the post-cat O2 sensor. My car was originally a California car so it originally had two cat system. A pre-cat built into the exhaust manifold downpipe, and a secondary cat downstream from there. O2 sensors are placed before and after the pre-cat. The secondary O2 sensor is just for emissions, so it didn’t impact the use of the car. I still wanted to fix it, but wasn’t in a rush. [Read More]

NB Miata project – Purchasing a Mazda Miata

My last post covered my experiences with my first project car, a 1987 Honda Accord. At that end of that post I mentioned that I purchased a NB Miata to replace it. Today marks six months since purchasing my Miata so I thought I’d start a series covering my experiences owning it.

This is an introductory post where I cover what a Miata is, why I chose it, the original condition, and how I prepared the car for what was to come. I have several other posts that I’ll be publishing in the near future covering the first six months of ownership. [Read More]
