Knew a guy back in school who used to race his. This was back in '79 (damn, I'm old).
Anyway he was goofing off one evening with the nitrous, revved it a little too hard and it grenaded on him.
Funny thing is there's been an awful lot of serious racing done with various versions of the Ford fours over the years. If you've got the money to throw at it you can get some amazing results.
Fond memory of a race I went to at Riverside, the Times Grand Prix of
Endurance. The fastest cars were the prototypes, V12 Jags, Porsche 956 turbos, Porsche turbo, Buick Turbo and V8 Chevy powered Marches. The fastest of the lot were the Ford Probe 2.3L turbo fours.
(note: Ford called a bunch of racers and concepts "Probes" before they came up with the Mazda based street Probe).
