Head Builder for Mazda MX-5 NA NB

Our comprehensive head builder for the Mazda MX-5 NA NB allows you to spec your perfect head. You’re able to see all possible camshaft combinations and what components you need to install them.

Camshafts can be selected from the dropdown for each engine. Here, you can choose from drop-in, short-duration cams all the way to massive high lift, high duration options that require a host of parts and machine work. Each camshaft has a description that outlines the parts and labour needed for installation.

Cams that require head machining have significantly larger lobes that come into contact with the casting of the head. We recommend sending both your head and cams to a machine shop and getting it professionally clearanced to ensure proper fitment.

For 1.6 cams that require retainers, you’ll need to upgrade to 1.8 retainers. All 1.8 cams should work with the standard 1.8 retainers.

If you have any questions about options or want to talk to us about your head building plans, give us a call on +44 (0) 203 795 0515  or send an email to [email protected]bofiracing.co.uk.
