20 or 22 teeth mx5 clutch

[ferny]

So, I may have had a bit of fun in the car today and now the clutch is a little unwell. Great for testing the wobbliness of a jelly when you pull away though! Still, I had planned to replace it anyway. Easy enough, jump on Euro Car Parts, put in my registration and pick my clutch. Except they list three, two have 22 teeth and one 20. I assume they mean splines? Without removing my old clutch from the car how can I tell which one to buy? It's a (August?) 1991 1.6 car.

Best bet's to phone your local branch, I've found their online system often throws up multiple options based on just the car rather than your specific reg. In store they should be able to help more.

If they don't know, then maybe give MX5parts.co.uk a call. They list different clutches for 1.6s and 1.8s, which I'm guessing's the difference between the ones ECP list.

Cheers. I'll buzz them later. I did a Google search and it threw up a thousand results and opinions, some saying that the 1.8 and 1.6 use the same clutch. I went to mx5parts to see that they list different ones! I believe that the 22 spline is the 1.8, but again that's based on unreliable Google results.

Hi, according to this -

the 1.6 and 1.8 both use 22 spline, the 20 spline is for older Mazda models like 323,s.
