    ive lost my borgwarner cd but from mem its off a cummins 6bt but ill borrow another and let you know

    Google agrees with this. Jesus these things are cheap compared to VFs...

    i have no reason to lie and yes they can be

    You were unsure, I wasn't suggesting you might lie. I was saving you the trouble of digging up a CD tomorrow :)

    You try something similar to what a guy in the link did?

     
    I epoxied the metal sleeve into where those plastic bushings were. i think i put wax or some crap on the sleeve. then once it was dry i hit the sleeve out with a hammer. then i lightly sanded the inside of the epoxy and greased it. instant solid bushing for hella cheap.

    I once wrapped a steel tube that I think was from the top of the shifter, in some thin and solid tape and used that, extremely solid shifter feel, almost painful at times, it certainly hurt if you missed during a fast shift.

    as for part numbers, as you know I got the wrong one from wingers.

    Need to talk to someone onto it like boostin to get correct numbers

    The two you gave me will work for the replaceable bushes by the looks. My confusion comes from the pin you cannot remove ( which ill grind off as we spoke about ) and the bushes in there.

    Are they smaller as per the legacy picture or larger as per the two you gave me.

    From memory all four are the same, and you need to use another of the same bolts used to attach the shifter lever to it to replace the pin. Make sure you use a locking (aka friction) nut or it'll come undone by itself... not a mistake I'll ever make twice.

    Well headphones get he'll noisy if I don't keep timing low down low.

    And I disagree with you. If I pull timing it will not knock anymore so it's not pre ignition as it would still do it as it ignites without spark plug. Knock is where the flame front is not stable and create more than 1 flame front that collides.

    /quote]

    While it's not pre-ignition, it's ignition before MBT, your burn is completing before the crank reaches 16* ATDC, so it may aswell be pre-ignition. This will create the same rattle as knock, and it'll still come through the headphones, but at a different frequency (a knock sensor with appropriate filter will not register provided your timing isn't toooo absurd)

    You say it's not pre ignition but then turn around and say it is? Here is a quote from your source you supplied.

    Pre-ignition (or preignition) in a spark-ignition engine is a technically different phenomenon from engine knocking, and describes the event wherein the air/fuel mixture in the cylinder ignites before the spark plug fires. Pre-ignition is initiated by an ignition source other than the spark, such as hot spots in the combustion chamber, a spark plug that runs too hot for the application, or carbonaceous deposits in the combustion chamber heated to incandescence by previous engine combustion events

    Not pre ignition. It knocks less at high rpm because air mixes and swirls more and has less chance of knocking. That's a fact. Also stayed in your supplied source.

    I also don't see the need to have 30psi before 3000 so held boost at 13psi till 3000 then up to 27-33 depending on fuel type used.

    I said it's not, but with regards to its effects may aswell be, that is very different from saying it is. In any case, it seems you don't want to hear what I have to say so I will say no more :)

    It knocks slot easier at lower rpm due to faster burn compared to rpm. When it knocks its also alot more violent. Also particularly with v7 on but at lower rpm the cam and crank angle sensors read less voltage so make it harder for ecu to get exact position. Link have known about this issue for ages.

    I disagree with this statement. Knock is not a premature burn completion. However MBT does certainly shift to a more retarded timing at lower RPMs.

    Some light reading to clarify my point: What is knock vs pre-ignition? http://en.wikipedia.org/wiki/Engine_knocking

  7. My thoughts on this issue are a wee bit complex.

    Does more power lower down (forget boost, boost is just shoving more air in, that in itself isn't going to do anything strain wise) increase strain on rods/crank vs the same power higher up?

    - At particularly low revs and high load the burn may complete before the crank angle has changed all that much, while at first thought one might think that it would put undue force on bearings and things, I don't believe so, since that force is still going to be applied higher up. It's the same force however the engine speed is high enough that the burn is not unduly fast.

    - There's a psychological element to it since 'lugging' feels bad (and causes carbon buildup), but I am doubtful that lugging actually puts any significant extra strain on the bottom end unless the timing is unduly advanced where detonation takes over as the cause of trouble.

    - In terms of strain vs RPM. The crank is definitely under greater strain at higher RPM as it is moving faster and therefore, while the _amount_ of instantaneous strain (or strain per revolution even) doesn't change, it is occurring more often/shorter time and therefore total strain for the same time period is greater.

    Regardless of the above thoughts, is it anything to worry about?

    - I honestly don't think so given that many modern turbo european cars (VW Golf, Audi A1 are the two I'm looking at in this instance) run compression ratios greater than 9.5:1 (2010 Golf GTI, 9.6:1 as per http://www.netcarshow.com/volkswagen/2010-golf_gti/ ) and spool to full boost by about 1800rpm. Subaru also have done this in the past, BC5 and BF5s equipped with the VF10 spooled to full boost by around 1600-1800rpm and the BE5D TT spools to 1bar+ by 1400rpm.

    Looking at the above points I personally disagree with Sultan/Mike and concur with MercuryFree/Rob

    Quick hijack, is it possible to buy new seals? All of mine are perfect but the ones on the rear side windows are ultra s*** and filthy so I can only assume the others have been replaced at some stage.

    Filthy or just oxidised? My BE has some serious oxidisation issues on the trim surrounding the fixed side windows (quarter glass) I'm not sure how to fix them but I'm betting they can be bought new

    When we install the legitimate Laser Star "parking sensors" we add a kill switch. That way should they happen to interfere with police lasers, you can kill the power and that way the cops will get an accurate reading. In the interest of safety, we recommend you slow down before reaching for that kill switch.

    25 demerit points when doing 150 KMs is better than what would happen without a jammer.

    Keep it legal ya muppets. in any case, 150 is instant disqual.

    V6 ECU is tunable using software similar to ECU TEK, just ring WRC developments or STM in wellington

    We were only talking about pre-v5 ECUs, V5-onwards are all tunable but there's no 'open source' solution for anything prior to V7.

    Iirc, the avcs uses a different table(s?) in the Ecu when activated, so it's probably not going to do any damage. It's probably making less power as a result though

    Edit: OK, what he said ^^^ essentially

    Nope, The AVCS does not cause a table change. AVLS does, but on non-AVLS engines the only thing that causes a table switch is if you have a tonne of knock.

    Unless it has thrown a CEL, the ECU is ignoring the fact there is no AVCS. Because you didn't have exhaust-AVCS this should be okay, but you will as they said be down on power.

    I personally would still recommend fixing it.

    Worth noting that I can do this another way but you'd need to send me both ECUs which would mean your car was out of action for 1-2wks.
