    It really depends on how far you want to go and how much you want to spend.

    The first and best mod is the 3.4" pulley upgrade. I highly recommend doing a cold air intake.

    No such thing. Best combo of mods starts with one of these:



    Then go buy something that you can get some speed out of.

    There is nothing wrong with the little L67's sure they aren't a V8 but they have some potential. It's a shame they are under cooked from the factory, in fact, just like the naturally aspirated V6 ecotec they have had their throttle response dulled to save the driver from themselves. With a few basic mods you can wake these things up fairly well.

    to try and answer the OP original question
    1- upgrade the CAI
    2- fit 1:91 roller rockers with the new pushrods
    3-up grade the supercharger pully
    4-full exhaust , from headers to cat back I'd go for full twin 2.25 inch , or a single 2.5-3 inch
    5- custom tune .

    I'm there are others , but it depends on your budget .

    What immortality said is basically what the cops did when they used this car .. So I'd say that's a pretty good case for making it the best starting mod!

    I used to own one of these SV6's and I much prefer the LS1 .. Sorry ... Great car though... Enjoy :)

    if he wanted to go all out v6 then the ls motors would be cheaper - that was my thought -tough supercharged

    Why is when mentioning upgrading a 6, there are people that want to wipe the 6 and go straight for the V8?

    To me, there is nothing wrong with spending a few bucks on a 6, just to liven it up a little, without the expense of upgrading to a 8, just for the hell of it. Geez, the 6cyl car might have some sentimental value, or a case of the better the devil you know, that the one you don't.

    Yes, a little off topic, but it seems all to common place when even the words upgrade 6 come to play.

    Oh and sorry I can't add too much tech advise in this area

    Every state seems to modify cop cars, whilst in the cops hands.....It's is strange, that when these cop cars go to auction, they are mysteriously the same as an everyday car, with a few minor exceptions, that aren't performance based....The only performance modifications is the people that buy them from the auction who mysteriously think they have a fast car....

    The only performance modifications to any Police car in Aus that I know of was a batch of VK's that were done over by HDT way back in the day. Beyond that they had electrical mods for radio's and the like plus some got upgraded alternators to deal with sitting idling for long periods.

    It shows that the mods were general public available stuff......The wiring/alternators weren't really performance, just a necessity to run the stuff required by the force
