you should check out v6z24.com or 60degreev6.com...both sites will have more than enough info to get it done...but be warned...turboing these cars arent a walk in the park...hell most people have to undo the mounts and tilt the motor forward just to get at the back bank spark plugs. if you were gonna do any swap you can find Turbo Grand Prix parts which is a direct swap into your car...the pcm and everything bolts right in, with only needing to find a new spot for the battery cause of where the crossover and turbo sits. either way...buy a car thats turbo stock or dont, buy a daily driver for just that...put the money where it belongs...in the fun car.
ps. quad 4's arent the most reliable motor in the world especially if you compare them to the track record of the 660's
pss. what year blazer came turbo????
