Hi everyone I’m a student in year 12 in South Australia, and as part of the new SACE i am required to undertake a "research project" and i have chosen to research "the horsepower capabilities of the ECOTEC v6" i was hoping that i could get some help from you guys, who have any knowledge or experience in modifying the ECOTEC v6. i would love to know what power is achievable, both in a NA application and forced induction. Are the cars still reliable once modified? what increase in fuel consumption could be expected once modified? What would some of these modifications cost? Would the car remain street legal once modified? Please keep the comments clean and as positive as possible, as some of this may be may be published in my final report!
