2024 Mazda CX-90 Debuts: Three-Row Hybrid SUV With Miata Tech, 340-HP I6 A PHEV version using Mazda's e-Skyactiv 2.5-liter engine with 323 horsepower is available, too. Jan 31, 2023 at 11:00am ET
If you aren't porting/deshrouding, don't waste time/money on O/S valves. The 99-00 Miata have the BP4W (non VVT) head casting. Swapping the standard BP4W intake cam for the slightly bigger BP5A cam from the 04-05 turbo model is a few more cheap and simple hp. The 01-05 Miata has the BP6D VVT head.While the NB didn't sell in the same numbers as the first-gen Miata, Mazda did move plenty of them off the lot. NBs saw the milestones of the 500,000th Miata and the 750,000th Miata.
