They went above and beyond to help me with my purchase. Best company out there hand down.
I recently installed the Outsider Garage throttle body adapter on my R32 GTST with an RB20DET and Zerofab manifold. The adapter allowed me to swap in a KA24DE throttle body when I couldn’t find an OEM RB20 throttle body, and it fit perfectly. The main advantage of this adapter is the ability to run an OEM-sized throttle body, which significantly improves drivability and throttle response, especially at lower speeds, compared to oversized aftermarket options. After swapping the TPS to match my harness, I easily calibrated it in my Haltech Platinum Pro, and the car has been running great ever since. The adapter makes the car feel much smoother and more responsive, offering better idle stability and OEM reliability for street use. If you’re running a Zerofab manifold and want to retain OEM throttle control, this adapter is a great solution.
