The proper way to add forced induction is to
1STinstall cylinder sleeves & stronger pistons that also lower compression. This requires total engine disassembly, so basically you need to rebuild the engine, while you are "in there". This will cost $10,K+. Naturally you will want to start with a 3.2L+ engine for max power, so now you have 300+HP & 280+ ft/lbs torque with is plenty for any 3000lb street driven car.
Now if you want to add power,complexity,heat,cost & lower reliability to your car forced induction is the next step.
