    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!

    welcome to JC.

    if you do a search in the V6 section but change the parameters for time to 2 years you will find heaps of threads about V6 builds and some of the results.

    there is a good thread going about some dyno testing of different intakes and LPG at the mo

    Thanks everyone for the reply’s, RUF 231 I would love to take you up on that offer, pm me with your details so i can get in contact with you.

    so, what I’m thinking to improve horsepower you would need

    Extractors
    High flow cats
    2.5 inch cat back exhaust
    A good cold air intake
    Maybe a set of high ratio roller rockers
    Custom tune

    and from then on

    Forced induction?

    If anyone can point me in the right direction that would be great!

    Thank you

    You are welcome to spend 5-10k on my motor, turbo/supercharger, stroker, cam or whatever you think is best. I don't mind helping out for your research ;)

    There are heaps of options before you go forced induction, cam, headwork, NOS, cubes etc.

    so what exactly are you after? our mods and the power they yield and our experiences or just how much can be done in na or psi builds?

    For straight out power the best HP for dollar is Nitrous, however then comes sooner or later having to strengthen everything anyway.

    Depends on what you would call a "Real life" situation. Personally I've seen guys spend $10k on an Ecotec, and to me thats just insane. I'm planing on spending about $5k for a turbo setup, that would be more real-life. Or you can go your general owner who would do the normal exhaust, CAI, rockers, tune and that would come to about $1.5k.

    Thank god I did the old SACE system, there were enough "projects" and "assignments" as it was let alone another bloody research thing (mind you I did the suicide 5).

    for the limits of this progect 10 thousand on an ecotec isnt out of the question, i agree nos would help but for this progect the car must remain realiable enough to be used as an everyday runabout as well, and nos would eventualy make it unrealiable. I was thinking more along the lines of bolt ons etc.

    For a reliable daily I'd say you need plenty of low down torque. A decent set up for safe daily use, in my opinion only, would be:
    Full Exhaust: Headers, Twin 2.25" pipes. (Budget max of $2,000)
    4.3 Stroker Kit : $2,500ish
    Aluminium Heads : $3,000
    69mm throttle body : $220
    Mace 25mm manifold insulator : $220
    Mace 12mm plenum spacer : $150
    And that leaves you plenty of cash for a MAFless tune.
    Feel free to debate my list/prices, there's no way I've remembered everything.

    I've spent about 3grand max on a turbo setup including fuel system, making my own manifolds, intercooler, all pipe work, reverse plenum, exhaust and tune and I ended up with 267rwhp and I've been driving it as my daily for about a month with no problems and is still pretty good on fuel. Out of a full tank of 98 I get between 450-550kms

    I just got an exhaust put on my VY.

    Pacemaker Extractors
    High Flow 100cpsi Cats
    2.5in Sports Exhaust

    Went from 118rwkw to 130rwkw. Everything else on the engine is stock although i have just put a high flow filter and new spark plugs and leads on it but no dyno.

    Cost $1700 fitted
    (feel free to use the dyno graph as teachers seem to love graphs)

    I do have some graphs you could have. I'll post them up when I get home.
    As for problems, I usually just fixed it myself and then documented it on my ride thread.
