    Re: cosworth hybrid turbo onto cav turbo engine

    You can fit *any* turbo to *any* engine, provided you fabricate (or adapt) the necessary parts.
    However it's highly unlikely that they will match, as there are numerous little tiny parameters involved. So it will work, but will be nowhere near as good as the specially-designed item.
    Don't let them fool you that the 'hybrids' are the beez neez, spool faster, boost earlier, give far better top end, last longer and produce cooler charge, all at the same time. They don't.
    It's all give and take, mostly you give, bits you take - and if you don't like the way the car drives afterwards, tough!

    Hope it helps,

    John

    There is no such thing as a hybrid turbo, it just means something inside has been changed and it could be anything.

    The standard KKK turbo is a load of tosh and should be binned, Courtney do a manifold to mount a T3 (cossie).

    I'm sorry - I though KKK were much better than Garret - hence they are fitted to Audi, Porsche and loads of other top end cars.

    erm, actually they are a better quality turbo than garrett.

    Slightly different application but you don't wanna mention garrett turbos to a good friend of mine as they are always replacing them on the fleet of volvo trucks at the moment as the impeller shaft keeps snapping.

    OK then there is no such definition as a hybrid, it could mean anything has been done to a turbo.

    And the KKK fitted to the LET is not better than a Garret.

    kkk's are a much better quality turbo rnt they????

    im sure they are.

    and there is such a thing as a hybrid turbo. and yes it means something inside has been chaged, and yes it could be anything but generally the hybrid ones spin up at lower rpm so whatever they change they change it for a reason, ie to make it better

    Or to sell them for more money cos it has hybrid on the side?

    KKK turbos are the Saxo VTS's of the turbo world, bleh, spits on floor, wipes bum with vauxhall badge.

    Garett are more reliable, have better bearings (kkk's have skinny shafts, poor quality bearings and are in efficient) more availability of different wheel/housing combos etc, its like comparing a e55 amg to a mondeo st200 estate, the merc is better in every way, both quality and reliability.

    Yes people do blow up Garrets, but then again people blow up Cav transfer boxes, does this make them worse than Ford ones? And yes they stick KKK's on Porchers but then again they stick Eaton superchargers on Astons and they have a habbit of bits breaking off and getting sucked into the engine.

    And for the last time calling a turbo a hybrid means little more than something has been messed with, could be a 360 degree thrust bearing, could be a different sixe impella or compressor, could be anything.

    KKK are crap turbos ??

    Audi, Cosworth and Porsche (to name but a few) dont seem to think so.

    The KKK K-16 turbo is a pretty good unit for the C20LET. At stock boost levels it does its job well with the integrated manifold/turbo unit cutting lag hugely.


    Sure, when you go above 1 bar of boost its not great but then thats not what its designed for.

    I think you want to say "there is no such thing as a UNIVERSAL hybrid turbo" - which is true.
    "hybrid" is a synonym of "bastard" , as in some bits have been swapped/modified to better match a particular application.
    It just means that it's not identical to the 'stock' item, which, too, is arguably a hybrid (it was custom-made after testing dozens of variations, after all)
    The standard KKK turbo is a load of tosh and should be binned,
    Mine can boost to well over 20psi if needed, and it provides enough airflow for over 300lbft up to almost 5K revs.
    That's a lot of air being shoveled around, and the unit has 85K miles under its belt. Doesn't smoke either.
    It was designed to shift almost half the airflow.
    Tosh? I think not!...

    ...not exactly.
    You're confusing marketing blurb with measurable facts.

    Hybrids are meant to better match a particular setup (at the expense of inferior matching to any other setup)
    No, they don't generally spin at lower rpm, quite the opposite (although the marketing bull will claim otherwise)

    People usually shell out for 'hybrids' because they want more airflow at high engine revs - something that would quickly kill the stock units due to overrevving. Reliability at sustained high boost pressures is also a 'hybrid' aim, although these are not always proven.
    Just fitting a larger compressor wheel and/or a different turbine qualifies as a "hybrid" although performance may be impaired all around (remember that the manufacturer probably tested most of these hybridisation combos, but decided against them)
    Playing with A/R ratios is also hybridisation, but any which way you look at it, it's give and take (Bit like cams - is a wilder cam "better"? not necessarily, depends on the rest of the engine)

    I know for a fact that some well-know "hybrids" aren't worth their weight in scrap metal (just sloppily reconed stock units sold at a massive premium) You think that the punters notice? Nope! They're swapping a tired, smoking or siezed turbo with one that works, so it MUST be better, eh?

    So there
