Haltech engine management and supporting parts for the Mazda RX-8, 2003 to 2012. Standalone control for the 13B-MSP Renesis, plus the harness options builders need when something other than a Renesis ends up between the rails.

Nexus R3 and R5 plug and play adapter harness kits are available for both the 2003-2008 and 2009-2012 chassis, each matched to a Boomslang adapter harness so the install needs no cutting or splicing and can be returned to stock. The Boomslang harnesses are also sold on their own for cars that already have a Nexus, and the Haltech plug and play ECU option covers simpler setups.

For swaps, we build RX-8 engine harnesses in house for the K20 and K24, a 13B-REW harness for turbo rotary builds, and a DIY chassis jumper for anything that does not match a catalog part number. Injector Dynamics ID2600-XDS secondary injectors, Zestek Racing steering hubs, boss kits, and Velo modules, and a rotary compression tester fill in the rest.

Rotary is what this shop was built on. Every ECU here can be tuned remotely by us, on the engine we know best.
