Weโ€™re excited to share a small update on our Mazda 13B stainless steel cast manifold!

Our goal is to develop a cost-effective solution that allows fitment of the Garrett GBC37, creating a high-value bolt-on kit for all Mazda RX-7 FD3S drivers.
We are currently testing fitment and aiming to move into production for the next samples soon โ€” stay tuned!

They say variety is the spice of the tuning life, and we have something different in shop for a custom dyno calibration. We love tuning and couldn't turn this cool 1.6l miata away. Owner installed a track dog supercharger, bigger injectors and 6 speed trans. It came in with another brand ecu and problems starting and running. So we installed a haltech ecu and started the tuning process and ended up with a clean pulling engine at 9 psi boost and 151 hp and 130 tq that's just a Lil ripper and allot of fun!
