Buck to the OPs question. Just remember the K20A civic engine was first seen in 2000. The BP-ZE engines from 323s/mx5 were first seens in 1990. There is 10 extra years of engine developement in the K20A. And considering the 90s saw massive engine advancements compared to any other decade. It's not surprizing the K20A is massive leaps and bounds above a BP-ZE

Thanks to the OP for the question. I had noticed the cranking and thought it strange compared to other cars I had dríven but gone no further than questioning it in my mind.
Thank you for all the explanations. Makes a lot of sense and part of the reason I love the MX5. So simple and and fun to work on (mostly).

On the other hand I've got an NA8 and I've always loved the fact that it starts first time every time. It's one of the fastest starting cars I've known. Never, ever noticed any significant cranking. These cars are about 20 years old and it wouldn't be surprising that a lot of them need an ignition fresh-up: connectors, coils, plugs and leads, starter motor and leads, earths, sensors are all getting tired.

Personal attacks are not welcome on this forum.

If you want to be a keyboard warrior do it on another forum.

This forum is about MX-5s.
If you had access to a car like this, would you take it back right away? Neither would I.
