Few nameplates in Ford's modern performance catalog carry as much weight as Shelby, a legacy that traces back through decades of homologation specials profiled in our Shelby Mustang retrospective. The latest example to catch our eye takes that heritage and multiplies it several times over: a 2020 Shelby GT350R that's been reworked into a 953-horsepower, twin-turbocharged street car, and it just surfaced for sale on Cars & Bids.
Under the Hood: The Fathouse Performance 1000R Package
According to the listing, this GT350R's 5.2-liter flat-plane-crank V8 has been fitted with the Fathouse Performance 1000R Twin Turbo package, and the seller reports a dyno-verified 953 horsepower and 674 lb-ft of torque at the wheels. The setup pairs a pair of Xona Rotor dual ball-bearing turbochargers with a 4.5-inch air-to-air intercooler, stainless steel turbo headers, billet merge collectors, and turbo blankets to manage heat. Fueling comes from Injector Dynamics ID1300x injectors and a twin-pump return-style fuel system, all controlled by a standalone MoTeC M150 ECU running Johnson Tuning calibrations for both 93-octane pump gas and E85.
Driveline, Suspension, and Stopping Power
Power gets to the pavement through a built TREMEC TR-3160 six-speed manual transmission, backed by an RPS triple-disc carbon clutch and a QA1 carbon fiber driveshaft, hardware chosen specifically to survive four-digit torque figures without shredding. The seller also fitted an MGW short-throw shifter and a 1000R billet weighted shift knob for quicker, more direct gear changes. Underneath, a BMR Suspension anti-wheel-hop kit and Ford Performance lowering springs work alongside the GT350R's factory MagneRide dampers, while 19-inch Signature SV101 monoblock wheels wrapped in Toyo Proxes R888R tires handle grip duty. The factory Brembo brake package remains in place to rein in all that added power.
Inside the Cabin
This particular GT350R rolled off the line with Equipment Group 920A and the Technology Package, adding niceties like a MagneRide-equipped chassis, Recaro sport seats trimmed in cloth and Miko suede, and factory Brembo calipers, on top of the model's standard carbon fiber wheels and Track Apps data logging. The seller notes the car retains its factory 19-inch carbon fiber wheels wrapped in Michelin Pilot Sport Cup 2 tires as a spare set, along with two keys, the owner's manual, a Fathouse Performance welcome kit, and extra spark plugs, turbo filters, and Toyo Proxes R888R tires.
Condition, History, and What to Expect
The seller purchased this GT350R new in May 2020 and has been the sole owner since, with the Carfax history report showing no accidents or mileage discrepancies. Only about 5,700 miles are on the odometer today, and the car has reportedly spent winters in a climate-controlled garage. Cosmetic imperfections noted by the seller include some small chips on the front end, a scratch on the rear bumper, and light scuffing on the interior door panels, minor wear consistent with a car that has clearly seen some spirited use. Given the extent of the drivetrain work, the seller also points out that this Mustang may not pass emissions testing in every state, something prospective bidders will want to factor into their plans.
Final Thoughts
As of this writing, bidding on this Kona Blue GT350R sits at $50,000 with several days still left on the clock, a starting point that seems light given the scope of the twin-turbo build and the documented ownership history. Whether it sells to a track-day regular or a collector chasing something genuinely different from the usual modified-Mustang playbook, this GT350R is a reminder that Ford's homologation special makes an excellent starting point for serious horsepower.
