Cosworth teams up with Borg Warner on the new EFR Turbocharger

biggest problems with fitting them to an existing kit:

Turbine Inlet Flange: Looks to be a Garret GT style flange which means it would bolt up to the GTM manifolds, but not to the GReddy.

Turbine outlet: V band neither company uses this and it appears to sit at an angle which means custom down pipes are a must.

Wastegate: The wastegate set up is quite different than the traditional turbos. The bracket and actuator pictured would not work with either kit. The GTM bracket may work but the actuator arm is set up as a clevis style where that is not. GReddy kit is only offered as an external gate so it would be 100% custom on that.

Plumbing: Can't tell from the pics but the water and oil inlet and outlets could also be different. Could be as simple as a different thread pitch to different orientation.

Bottom line its all do-able, but probably not worth the added cost for the gain over the Garret turbos.
