I am assuming you re talking the earlier 91-92 3.3L 964 turbos vs the 993TT. The 94 3.6Turbos surpassed the 993TT a long time ago with average high mile cars in the $225k range and nice clean examples breaking the $300K price point.

These are all very different cars. The 3.3l uses the older 930 engine essentially. far more civilized than the 930's but still a little laggy and not much faster than the 89 5 speed 930 in stock form. These can be easily modified to add power with simple bolt on mods. Power is intoxicating when done right as it comes on with a rush and although the cars are not fast by todays standards have points of power that will take your breath away.

The 3.6L is a bit different still raw and visceral like the 930 or 3.3L 964 T but a bit more civilized with a better off boost feel and a bit more power and torque. 2nd and 3rd gear is surprisingly fast for a car 25 years old.

Both these cars use the old heavy rear trailing arm suspension which is a bit slow at reacting but these cars offer a unique driving experience with a lot of road feel and a talent needed to drive at speed. As I said when the power comes on it is a rush and can be rather addictive

The 993TT is a very different ride. Far more civilized rather flat power curve AWD a bit heavier and although faster on paper off the line I have never had a 993TT leave me behind in my 3.6T with slight mods. Usually in 2nd or 3rd gear I will gain on the 993TT even with updated turbos and tweaks. A far more civilized less raw and visceral experience.

They are all great rides each uniquely different. I spent several years searching for the turbo i wanted and in the end after driving them all I settled on the 964 3.6T Last of the single turbo RWD air-cooled Porsche's. Classic lines and looks along with a driving experience that IMO is one of the more unique and exciting of these cars.

Pricing is all over the place and there are very few of these that are in what I consider nice condition. Many of them have hidden issues and will need $$$ dumped into them to make them right so do you research and test drive as many as you can. Don't buy them as an investment but because you like it and you will be happy with whatever you settle on.
