Buy a 180 degree thermostat. A cool air intake. See if you can go to junkyard and find a supercharged 3800 motor in a car and take it out, or you can get a used one for about 200 dollars. Switch out the pulleys the 3.4'' and bam you are pushing 290 h.p. easy in a sleeper se. I dont know how to build up torque. However i know that the ssei (series 2) has a torque rating of 280 ft. lbs around 3k rpms and is very steady through out the rpm curve. You should have no trouble running sub 15'* or 14'* with your bonnie. (dont forget some platinum tipped spark plugs and mobil 1 synthetic) Feed your supercharged motor over 91 octane. And keep the fuel system clean.
