1977 had 1.5 boost guage, plus it was the first year with boost guage built into tach
some 77's had hand throttle carried over from prev year too
Air vents on dash was introduced ,Blapunkt Blamberg radio cassette was standard,
adjustable rear spring plates introduced, cuckoo clock spring introduced on clutch to keep tension,
All supposedly came with a power brake booster but ive seen some stock that don't,
The Rear spring plates were split with eccentric adjusting this hasn't changed either,
the Sway bar was backdated by factory to 74 models 20mm front and 16 or 18mm rear,
1977 were also first year using divalar studs
they also had different fuel injection and modified wastegate but I avent found out what at this stage,
77 Euros are 930/52@ 260hp, while us engines are type 930/53 at 234hp, I think there was also a 930/73 engine available which put out 590hp, like 77 cars it was a mix of old and new, Special order cars had 934 intercooler with the mechanical injection of the 935,
Also in 77 porsche introduced and raced the ;BABY, 1,400cc that put out close to 400hp
also in 77 Porsche won the world championship with a cis bosch twin turbo car, plexiglas rear window, they made 20 of these cars, I def wouildnt mind one of them extra turbo was used not for extra power but to improve throttle response yeehaa
Yep, I have a few friends that had concour 77 930s, both came with 15s.
