Supercharger adaptor GM M90 baseplate AS0510RC

AUD $425.00


Eaton M90 GM super charger adapter plate can be drilled, welded and machined to suit most manifolds and plenums when converting the commodore v6 blower to other engines. The sand cast adapter plate has provisions for the bypass valve and is sold as a raw casting. This gives a great start for your DIY supercharger project.

The adapter is universal and will accept both Generation 4 and generation 5 Eaton m90 superchargers. The top of the adaptor is designed to use a standard commodore type L67 supercharger base gasket.

The adapter can be welded or machined for your own supercharger fit up. the discharge hole is the same size as the weiand 142 supercharger. We would not recommend trying to fit this adapter to a manifold that is designed for use with a 4 barrel carb. A supercharged engine will require a plenum volume larger than what is designed for non supercharged single 4 barrel engine. The unmachined casting is 20mm thick

You are buying the raw unmachined adapter casting only, it does not include gaskets or studs
