Another successful project in the books 🔧

This 2005 BMW E60 came in for a full drive-in, drive-out conversion to a ZF 8HP gearbox — and what a transformation it turned out to be.

We installed an 8HP70 gearbox sourced from a 2017 BMW F10 530D, paired with a 10-pin 8HP shifter from a BMW F30. A custom-made adapter was fabricated to perfectly suit the M57 block, while also accommodating the original starter location on the bellhousing.

To bring everything together seamlessly, we integrated a CanTCU controller to manage communication across systems, along with the necessary coding on the stock CAS2 module to ensure everything runs harmoniously on the same bus.

Replacing the original 6HP26 with the 8HP70 has completely changed the car’s characteristics — smoother shifts, improved responsiveness, and a much more refined driving experience.

Drive in. Drive out. Transformed.

We’ve just finished getting this GC8 Subaru Impreza EJ20 ready, completing the CAN integration and tuning, with plenty more still left in this setup. This is one of ProspeedParts shop cars that they built, and here at Boost Brothers we handled the CAN integration and tuning on a Link ECU, hard-wired PDM25, Blink Marine keypad, and an AIM dash.

The results speak for themselves at 630 hp with 800 Nm of torque, laying down a solid foundation with a lot of potential still on the table for what’s next.
