The 2023 Mazda MX-5 Miata: pure driving enjoyment. With its ideal power-to-weight ratio, you feel as though your MX-5 is connected to you, anticipating and answering your every command.
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.
The 116-hp four pushes the Miata from zero to 60 mph in 9.2 seconds and to a top speed—with the hardtop on—of 116 mph. Those aren't the sort of numbers that test-results buffs drool over.
The 1.8 engine: pros and cons. According to Mazda, the 1.8-litre versions of the NA MX-5 Miata have up to 129 HP from the factory. The 1.8 models were produced from 1994 to 1997 at a smaller volume than the more common 1.6 models.
There are Miatas out there with turbo'ed 1.8L engines putting as much as 400 hp to the ground. The really insane ones, with stroker kits, fully ported and polished heads and monster turbos, have been reported to go well over 700 hp. By that time you will have $10,000 plus just in PARTS added to the engine, however.
