I'm considering buying and building a miata for endurance road-course racing, and this looks like a great resource. I have alot of experience with KL engines, so I might throw one in said miata. Who knows?

Thanks!

Welcome! The BP fits and has been proven in enduro racing in the 140-150 range, as have ecotecs in the 170-180hp range. There’s a certain group of enduro racers that love constantly fighting an up hill battle, and I’ll never understand them, but that’s your choice. There’s also a j series, lfx, or jag aj30 kits to consider if you’re dying for a v6.
