MGC GTS SEBRING RECREATION FOR SALE

Postby sandywashburn » Wed Jan 25, 2017 9:26 am

Since 1969 I had dreamed of owning one of the two MGC GTS Sebring factory race cars that competed at the Sebring 12 hour races in 1968 and 1969. I saw RMO 699F compete at Sebring in 1969 and then saw it at the New York Auto Show that year. This car was the replacement for the competition Austin Healey 3000 factory race car. 40 years later, I decided to build my own recreation of the MGCGTS Sebring race car with modern engine, suspension, brakes, and safety equipment to compete in time trials at many of the famous race tracks in the Northeast, including Watkins Glen, Lime Rock, and Mossport.

In 2010, my son , Bill Washburn, founder and co-owner of DENTSPORT GARAGE. and I designed this improved MGCGTS with a 1990 Toyota Supra 1JZ double turbo engine and Toyota T154
5 speed transmission, custom double wishbone independent front suspension, rack and pinion steering, six caliper Wilwood brakes, custom Watts linkage rear suspension, Penske adjustable racing shocks, a race prepared body with full roll cage, and SCCA mandated safety equipment. We moved the firewall and engine mounting points ten inches behind the stock mounting points, like John Chatham did with his own competition MGC GTS, which resulted in the car having equal weight of 525 pounds on each wheel. The car has Australian Superlite Mag wheels, Toyo R888 race tires, new oil pump and timing belt, new high power individual coils, , and Dave Craddock flared front fenders, front valence, rear spoiler, and MGC hood.

The engine and transmission are low milage Toyota JDM units sourced from Japan using an APEX adjustable ECU and custom wiring harness. The custom 3" dual pipe stainless unmuffled exhaust system produces a sound similar to a race prepared Jaguar XKE. A video of the dyno run is available to demonstrate this.

I believe that this unique recreation represents an ideal MGCGTS Sebring model. The DOHC six cylinder Toyota 1JZ Supra double turbo engine has more power, a much higher rev limit, and half the weight of the MGC Healey derivative engine. It is also more appropriate to the car than the numerous V-8 and V-6 powered MGB conversions. I can say without hesitation that this car handles like a well balanced race car, with an ideal power to weight ratio and brakes matched to the available power. Before the MGC, I had built and raced a Factory Five Cobra, which is a very well engineered race car. The MGC is much more predictable and comfortable to drive on a road course than the Cobra, and is much safer with its proper roll cage.
