Ford sold 369,936 Mustangs in 1979, of those, only 5,763 were Turbo's which is about 1.5%.
In the first year of the 301 Turbo V8, Pontiac sold a total of 50,896 Firebirds, of those, 22,176 came with the Turbo which is about 44%.
And what about the 1978 Buick Turbo? Well they only sold 30,507 of them...
I guess that Ford Mustang Turbo wasn't near as well marketed as you thought...:banana:
The Ford Mustang traditionally was sold with low powered 4 and 6 cylinder engines. Only a small percentage of Mustang sales over the years were sold with "high performance" (and I use that term loosely) engines. It was a car that was targeted at housewives and school teachers, because as you pointed out - they were cheap cars.
I guess that's why I was never really interested in the Mustang - it was a cheap, low powered car. The standard engine in 1964 was a 170 ci 6 cylinder with 101 HP, the next optional engine was the 260 ci 2bbl V8 with 164 HP and the top of the line was the 289 ci 4bbl with 210 HP.
My first love was the GTO and the base engine in 1964 was a 389 ci 4bbl V8 with 325 HP, with the option of a 3 deuce setup with 346 HP. I was 10 when my '64 GTO was built - and by 10 I was reading the automotive journals and I remember reading the Car and Driver magazine article where they "compared it" to a 1964 Ferrari GTO...
A few years ago I replaced the original 389 ci 500 cfm Carter 4bbl (now in storage) with a 30 over 1974 455 (462 ci) with 1971 # 96 heads (9.5-1 compression), 1969 stock intake, Crower 60243 cam and an 800 cfm Quadrajet.
