Honolulu fish wrapper ran this add: '83 308GTSI, 32valve, twin turbo excl cond,red w/tan $35,000. Twin Turbo ??? yes? no? BS? "The 308 series also spawned some competition development using the model as a base. A brutal 308 based twin-turbo model was developed by Carlo Facetti to contest the 1980 World Endurance Championship. He called it the Carma FF 308 and while blindingly fast it suffered from reliability problems and the project was soon abandoned." Kinda makes ya wonder WTF? Anybody know if there was a production Twin Turbo 308 built in 83?
