I am considering the purchase of a last 70s early 80s Porshe with the idea of modifying it to suite. Perhaps put a slan nose kit on etc...
I have some experience with expensive cars having a Jaguar XJS for many years of which I have been reasonably pleased and is my daily driver.
My mechanic used to work at Down Town Fine Cars (Toronto) where they serviced mostly Jag's, but also Porshe's and Ferraris and he now builds a lot of custom cars.
I discussed with him buying the 911 as above, he recommended buying a late
80s model the rational being that cars with electronic fuel injection and mass air (???) are easy to turbocharge / supercharge. He indicated other models could be turbocharged / supercharged with not as much horsepower increase. In other words words without the mass air I could only expect a 50 hp increase, whereas with the increase could be has high as 200 hp.My idea is that if I am going to go to the trouble of upgrading to a Turbo body, I would like to get turbo performance. The suggestion was made to go to a supercharger and not turbocharger as there would be little performance differance but less engine modification would have to be done. Appearently the enginee compression should be reduced in an Enginee if it's turbocharged in order to avoid damage to the head gasket which usually involves replacing pistons.
I have tried to read a Porshe buying guide but it doesn't seem to indicate which model of Porshe 911 I can expect to meet the modifications (ie. the earliest year).
If I am going to partially butcher a car I don't want it to be an expensive one.
