Sounds like quite a machine! I have and '83 and an '85 Quattro coupe
up here in Toronto. The '83 is in bits in the garage undergoing (a
slow) rebuild, 10 years of Canadian winters and 230K km having taken
there toll. Both cars are stock except for some body work
modifications on the '85.
I have been, since the early 80s, a big quattro fan, growing up in the
UK where the cars are more common. Anyway, I would like your advice on
increasing the horse power to somewhere around 230 (I like the idea of
variable boost). Money is an object, and solutions like computer mods
that can be easilly ported between cars would definitely be an
advantage for me.
I'll probably have to replace the turbo on the '83 during the rebuild
and I am in two minds whether to rebuild the original motor (which was
running well when I took the car off the road) or try and find an '87
turbo motor with a knock sensor? I have spoken with a very
knowledgeable mechanic here in Toronto and he strongly recommends the
knock sensor equipped motor as the starting point.
As for computer mods, I have Ned Ritchie's literature and some from
two other companies all three offer about 230hp, one of them (a
British company Turbo Boost?) offers 265hp for a 150 pounds sterling.
Now I know the European cars are 200 hp stock but 265 hp for 300
candian dollars seems extremely good value, even if I have to buy a
I guess the point is I am rather confused about the best way to modify
the 160 hp North American model and don't want to make an expensive
mistake. Your thoughts would be greatly appreciated.
By the way since all the parts are out of the car at the moment, I was
wondering if you knew if there are parts available to modify first and
second gear to longer ratios. One change to 60!
I was also reading the Audi Quattro Gold Portfolio (excellent book)
article on the '84 rally spec quattro which had larger vented rear
brakes and possibly larger fronts (I need to check the spec on the '84
rally car tonight). They consistently recorded braking times ol less
than 3 seconds 60-0 mph, with a "Car" test best of 1.9. This apeals to
me almost more than increasing the hp. What brakes are you running and
what would you recommend.
thanks and regards, Mike
