    Turbo replacement decisions

    Very soon i am doing a few big (costly) jobs on my car one of which is the turbo.

    I quite like the sound of putting in a bigger turbo but i dont really know where to start looking. When people say a hybrid turbo, is that just a bigger turbo or a similar one with different components? For example, do people put the 170bhp turbo in the 140's or wont it fit.

    Will i end up paying alot more for one of these uprated turbos? at the minute midlands have quoted £370 ish for a refurbed OEM with 2 years guarantee.

    Just a thought but does adding a bigger turbo create more wear on the old clutch i have in?

    Any information on this would be helpful thanks!

    Bigger turbos will cost more as they are physically bigger for one and the process of just chucking a turbo on isn't that simple.

    You need mapping to suit the bigger turbo for example, which isn't cheap at all.

    There seem to be numerous companies offering hybrid turbos for the TDI's. I've just put up a similar post as I'm thinking of going up to a stage 2. Darkside Developments do what appears to be a decent 'budget package' for a new turbo/map and from what I've read seem to come recommended.

    I know little on the subject though so will watch both threads and see what comes of them. All I know is the more I read, the more the costs spiral!!

    Here is the link to the thread I've started...

    Many People Running Stage 2 (or more) on a 140 TDI

    And here is the package I mentioned...

    Darkside 1.9 & 2.0 TDI Budget Turbo Kit inc Fitting and Mapping - Darkside Developments

    I think my clutch is on the way out (although yet to be properly diagnosed) so that's a cost I need to add on regardless. Clutches seem to be a bit hit and miss with stage 2 from what I've read...some people say they've uprated, some people seem to manage on the standard. It's bound to put more stress on the clutch so maybe it's just a case of luck and the currect condition as to whether yours lasts the distance or not?!

    Your best option is as already mentioned is a hybrid turbo. However as mentioned again you'll need a remap. What hasn't been mentioned is if you're going to the hassle of a hybrid you are best to upgrading your exhaust system from turbo back and you'll need an upgraded clutch such as a Sachs clutch to cope with the extra torque around 400lbft. Your standard air intake is more than capable as well as the intercooler however if you find a hole in your pocket you could upgrade these too, to a lets say a forced induction kit and a forged front mount intercooler.

    I got my Turbo Dynamics hybrid for £500 then fitting + stage 2 remap from amd = £800 totalling £1300 for 200bhp... ive heard anything about 210bhp then things need uprating like the clutch.

    Id like to get the turbo back exhaust but thats another £900 then £700-800 new clutch, hoses, injectors etc etc for 260bhp EXPENSIVE!
