Supercharging a non-turbo wagon

wondering what things i'd have to meet before going about supercharging my car... I'm tired of going slow...

expensive proposition and you won't get much hp/torque gain from the mod.

Best bet is to sell the car and get a turbo wagon, then you can tune it for a significant hp/torque gain.

You really don't want an older head gasket in there with the higher boost pressures. Or old O ring seals or old pistons, or old rings, or worn bores, or old stem seals or valve guides/seats. Turbo exhaust valves would be a good idea: http://cgi.ebay.com/ebaymotors/ws/eBayI ... K:MEWAX:IT

Some balanced forged rods would be nice, too.
Someone told me a Supra SC14 supercharger was a very good proposition, and he had fitted one to a N/A RWD car (though I don't know how long it lasted) One may fit where the A/C is on a five??

Best bet is to decide what sort of aspiration you require, start with an engine on a stand, strip it, replace anything worn down, and then decide what compression ratio best suits this setup, choose pistons that suit, then do some hand porting of the head, followed by port matching to manifolds. Water injection setup can help with detonation so while everything is off plumb this into the intake manifold. Of course you'll want to cool the engine oil so why not tap lines into the block to carry coolant hoses to a front mounted oil cooler. Now if you run an auto you'll want a NEW turbo radiator to carry this engine oil cooling.

Of course you'll need some custom guages to keep tabs of boost pressures and the like, perhaps even an engine oil temp guage.

Figure on spending 5-6K and you'll have a really great unique & quick vehicle almost as reliable as a stock factory Volvo car!!
Oh and did I forget to mention that by the time you work out all the engineering requirements and finally build the engine you will spend around one year sourcing all the parts? I don't know how the state laws work where you live but the last time I tried to modify a car I needed an engineer's certificate to state I had competently carried out the modifications so I could insure & register the modified car.
