Hi Kevin,
This thread comes up every so often when the performance bug bites. After running a blower for 6 years I pretty much have discovered the advantages & pitfalls. The SC most commonly used for this car is an Eaton M62

It is a roots style with some advancements in rotor design. It uses two mating rotors that drawer air in , compress it & force it out. The system used with a carburetor is described as a "wet" system since it drawers fuel & air through the blower. More current fuel injected technology has the fuel entering the flow after the blower & being regulated by engine management controls (computer). The beauty of the newer technology is the incorporation of a by-pass valve. What this does is open & close a circulation port that either allows boost or opens for normal driving. You can drive around all day & never see boost. It is truly "power on demand". It is vacuum operated & when vacuum drops in the intake manifold the servo closes the port allowing pressure to build.
There are as many positive as negitive misconceptions of performance and durability gains. The most common is that your engine will blow up & parts will start flying through the block. If you motor is within spec , your compression is under 8.5:1, you can tune your car properly and you follow the rules of any performance enhancement, you will have a very reliable motor with exceptional gains in performance. Is it perfect, almost. I would match idle & start-up ease with any stock TR & I know for sure that the street characteristics of my motor are far more tame than a motor of egual HP done the traditional way, carbs, compression and cam. There will always be something cool about lots of carbs that will never go away but if it's dollar for dollar performance , the blower is the best bang for the buck.
As with any power adder you should considor ignition, exhaust and driveline upgrades. I have abused the car using the stock trany & diff but eventally gave in to the Nissan differential & Toyota trany. These are defintly better units capable of handling the power.
The down side, more speeding tickets, the uncontrolable urge to constanly feel the acceleration & spending much more money on fuel. When your foot is in it you can see the needle go down
