The M1 K.C. Kits include all hardware and pipe work you require to bolt on the M122H supercharger.
The Supercharger & Intercooler Kit is not included. Please order the Supercharger & Intercooler from our shop separately.
The M1 K.C. Supercharger Kit also requires the use of the Straight Six Manifold. This manifold is not included in the M1 K.C. Bracket Kit. Please either order the Straight Six Manifold separately or by selecting the M1 K.C. Base Kit, that includes the Straight Six Manifold, above.
For the S50 and S54 engines with the ITB (Individual Throttle Body) we manufacture a custom manifold on order. Please contact us to request this service.
To complete the installation, you will require the following additional parts:
- an intercooler kit*
- vacuum hose
- an air filter
- larger injectors
- a boost gauge
- a boost controller and
- proper tune (reprogrammed ECU or standalone ECU).
All parts (except tune) can be provided by us on request, at extra costs.
*The M1 Supercharger Kit does not use the Silicone Pipe Kit and instead uses the intercooler setup. If you are buying the intercooler setup, it will consist of all the required pieces.
For tuning, we suggest the Ostrich II Piggyback for the OBD I (M50 – pre 1995). As for the OBD II (M52/M54 – post 1995) we suggest to remap the ECU or an Standalone ECU with a dyno tune from 3rd party tuners.
