Hi

I want to learn about this topic in the forum of Italian miata
[N.A.] Exintake su 1600
With a small modification to the original cams you can mount two exhaust cams and have an increase in power cheaply

 

The original intake cams

 

The small adapter to be built with the lathe

 

The adapter to be inserted in the exaust cams

 

A small plug to fix everything....

 

How it is held in place? I would imagine it to fail when the engine reaches operating temp. I've seen a 1.6 exhintake mod done by cutting the rear off and welding it to the exh cam, don't know how this lasted... But nice idea nonetheless, hope it works! I really need a lathe.
