Details
No, not as a swap that keeps all-wheel drive. The ZN6 gearbox is built for a rear-wheel-drive car, so it has no front drive output for the WRX's AWD. Forum posters discussing RWD Subaru builds think the bellhousing is close to the EJ's, but the BRZ starter sits high on the side where turbo EJs put the turbo. We found no documented GD install.
