The more I’ve been poking at the Miata, the more I’m thinking Ecotec swap. The BP6 can safely handle 200hp but let’s be real - it’s got 200k and will probably not live long like that. A turbo kit is also not cheap. So that has me thinking LE5 Ecotec swap sooner than later.

However, my online searches have turned up mostly beat up motors. Rust-belt, broken, cut wiring, horrible looking lumps. When I decide to pull the rip cord on the BP6, what is my best process for finding a good under 100k mile engine?
