Was working on a personal project to turbo my m40b18 and ended up investing nearly $3000 on the patterns required to cast a manifold for myself.
Just making this available if anyone else out there is wanting to do the same.
Manifold is cast from SG steel, coated in three coats of VHT paint, and the flange is for a GT28 turbo. (The fit has been checked in the engine bay on any regular e30 with m40 motor.)
Item location is South Africa. Can ship anywhere in the world for approx $100.
either email diytuninginfo@gmail.com or send a DM.
