I’ve been looking at scanners for a while to help when developing new products, re manufacturing obsolete parts and ultimately scanning engines and gearboxes to get accurate dimensions and models for future products and conversion kits.

I’ve bit the bullet and gown for the Revopoint Metro Y Ultra. Hopefully my laptop can run it!

Watch this space for upcoming projects.

A custom Cosworth YB to MX5 NC gearbox setup recently sent out to a customer.

This is the custom clutch used in the kit.

There is a custom 240mm 4 paddle sprung centre to suit the MX5 gearbox and YB flywheel.
This is clamped in place with a Helix cover.

These remote bleed kits have just been added to our website for our concentric release conversion kits for the 5 and 6 speed RX8 gearboxes as well as the 5 speed MX5 NC/N7 gearbox.

These kits make it much easier to bleed the concentric slave cylinder by having a bleed ni**le on the side of the box.

They fit through the side of the bellhousing ensuring they aren’t anywhere near the flywheel.

The original table bracket broke and tried to be glued back together so we modelled one and simply printed another.

Another MX5 to zetec/pinto kit gone out the door.

This consisted of the following:

🏁 Adaptor plate
🏁 Universal gearbox mount
🏁 One of our custom MX5 organic pinto 215mm clutch plates
🏁 N7 5 speed gearbox
🏁 Concentric release conversion kit

All of these parts are carried in stock and available for delivery or collection.

This is to replace an old type 9 gearbox. The customer can still keep their existing flywheel, clutch pressure plate and starter going down this route.
