  1. I know this is an old thread, but figured this is the best place to ask the question. Which loom dose the wires to the steering rack pressure solonoid attach to? Or perhaps tell me the colours of the wires on the loom that it attaches to? After investigation I found on my car it's not attached to anything.

  2. awesome. to me it initially looked as if there wasn't a constructive argument going on. but it's good to see the wealth of knowledge of the users of this forum has come out.

    makes sense that you get what you pay for. thanks for the information.

  3. Not all cheap turbos are bad, without even thinking Kandos and hypergears are proven performers without the price tag.

    as with most things of a "cheap" nature it can be one or a mix of things you have mentioned that cause premature failure. the failure can range from oh my turbos making a funny noise to why is there no boost, right up to i think a piston just shot through the side of my block.

    From what I have seen, the particularly bad ebay turbos are not balanced (or balanced at a low rpm to claim a low failure rate) - which is not a hard thing to do and is essential to ensure to the functionality and longevity of a turbo. you simply take it to a turbo shop and they attach it to a manifold in store and spin it right up to it's max rpm to ensure it spins freely and centered. if it is unbalanced they can cut small bits from the inducer or exducer to ensure it i within 0.00000 something of a gram off weight.

    all the more mid range to expensive turbos will have slight bits of metal shaved off, thats not a manufacturing fault. If it is unbalanced with a cheap material or a cheap bearing, at a high rpm the fins start rubbing against the housing and anything from some of that dust getting sucked into the motor to a single fin to the entire set of blades flying off at crazy speeds can happen extremely easily.

    Some other cheap exhaust housings leave large amounts of space between the exducer and the housing to mask this problem as well as other things and that causes positive boost to come on really late and gives you a useless powerband.

    makes sense, one other thing I've seen is the castings of the housings are quite thick, i'm thinking to avoid failures due to core shift, that causes flow problems, you can fix a lot of it, but there's only so many places you can reach with a die grinder. luckily you can open up the waste gate easily.

    what else needs to be done to get these going well?

  4. so, why are these cheap turbos failing? poor manufacture, poor quality materials, user/installer neglect? do the expensive turbos really out perform the cheap ones?

    just because it's cheap doesn't mean it's crap and so far the argument to buy the expensive turbo seems to be losing to me... by about $500.00

  5. The road from Goulburn to Oberon, one of the papers rated it as one of the top ten drives in nsw. There's a few rough spots but nice drive.

    I've travelled Bathurst to Goulburn and return once a fortnight for the last four years, always go via shooters hill Rd. Not sure if I've gotten bored of it once yet.
