    And that's all it will be, have heard a lot of people being sent the wrong turbo's and the ones that get the right ones just go bang very quickly.

    I've also heard of success stories.

    Theres a chap over on vauxsport that fitted an ebay special turbo to his C20LET and its been successfully producing big power figures:

    "463 bhp @ 1.6 bar and 347 lb/ft backed up with a
    458 bhp @ 1.6 bar and 348 lb/ft straight after"

    He also managed to blow the welds on his intake manifold, which is quite funny.

    Dunno if i'd want to risk wrecking a good engine with one, but afaik thats nailed onto a stock bottom end, so i guess its less of a worry.

    Dam,

    And it true I have also heard of good story's with ebay turbos, from what I can understand some of the ebay turbos are not ballanced or the waste gate is not fitted correctly due to bad casting which can be fixed with a bit of Dremerling.

    mostly because he has tried to weld two different sized pipes and has not got enough penetration or a decent cap weld on a bend that is stressed as it is....

    now this is a blown inlet mani! (scroll down)

    I was wondering the same. My engine code is BFB 1.8t what's the part number of the k04 turbo upgrade that I need to get. On seller asked my if I had a five bolt design which I have no clue of. Do I use five or three? Thanks!

    3 bolt is a petrol turbo and 5 bolt is a diesel turbo.
