    Quick question, im making a sleeper Audi A3 1.8t quattro, looking round the 350hp mark, does the big turbo for the s3 fit the Ko3s manifold? its a 2000 plate, looked about online and they usually say fits s3 but not 180bhp quattro? or fits FWD model?

    you will need the manifold and down pipe as well but the k04 from a s3 would never make 350 even with a hybrid unless you add nos

    This thread needs a bump, because we all need a bit of inspiration.

    I've got some interesting questions about the use of T3/T4 turbo's, but wondered if anybody on here runs one? General consensus I think is that they are antiquated, but a lot of american cars run them and I was wondering why people don't use them over here?

    Some inspirational pics -

    if youd have specified what turbos you had in mind then people wouldve advised and given constructive answers. Saying t3 and t25 means jack ****.

    And refering back to that thread, yes those turbos are old not very big journal bearing units. But if you can get one cheap enough and willing to do the work, whos to say otherwise.
    Technically ANYTHING can work

    I dont believe I said there was anything wrong with them.
    Old hat...

    and in the context of the grumpy arsey poster who started a thread asking BT questions earlier this week before deleting his post in a huff.... there are many turbos out there....... Pick one ;)

    T3 super60 was very popular over on vortex a few years ago...
    cheap as chips and decent gains

    journal bearing turbos get overlooked with the GT's but the bearing packs as std on GT's in my experience are fragile when they heat, which there is quite a lot of on a turbo, lol.. Plastic cages ffs... what a stupid idea???!?!?!

    anyhows.. turbo is just a component... its the rest of the bits to join it all together which will be the challenge (IF) someones looking to buy a kit, or if they have some skills to make their own stuff.. Huge saving to be made if so, and the worlds your oyster if you can make your own stuff to suit.

    My 6262 is journal bearing, I was to scared to buy a ball bearing after reading about so many failures on vortex.

    oil cooled only... but journal? is it?
    their bearings are considered weaker than GTs............. which is why my gt35 is garrett but with uprated bearing cage and only precision comp wheel and cover

    That is correct - also why I installed the turbo timer to let things cool down a bit more. You should see that sucka glow.

    When it dies, will prob go tial vband, new cartidge and upgrade cage.
