Another vote for the ECOTEC. In the Cobalt, it is rated at 260 hp. The 1/4 mile times are the same as my '93 Vette with an LT1 engine; 30 mpg isn't anything to sneeze about with that much potential. I understand an upgrade in blower pressure is easy and wicked! Some of the Lotus 7 (Catheram) replicas sound incredible with their side exhaust and 4 cylinders. Sounds like a neat project. Good Luck!
