    Hi everyone,


    I have a couple of technical questions and I'm interested peoples suggestions.


    I have a 2002 Audi A3 1.9 tdi quattro which had been tuned before I bought it and I don't know much about it's history. It needs a new engine due to smoking and oil leaks as it's now done over 150k miles. I understand that it has an uprated turbo but I don't know whether it's a hybrid or a larger standard unit (I believe that the seals are gone on the turbo so I expect it will need to be rebuilt or replaced). It has a large front mounted intercooler and a 3inch decat exhaust. It has also been remapped and I was given a print out showing it was at just under 230bhp. It certainly feels like it's close to that figure.


    I've bought a low mileage used engine to replace it and while I'm doing the swap I'd like to look into pushing up the power and torque as I understand that 270bhp it possible.


    So my questions are, do you have any advice on how I could identify what the turbo is and whether the engine had any other upgrades (e.g. injectors, camshaft etc). Secondly, could you advise me what parts I would need to replace or purchase to get 250-270ish BHP? I'd prefer to slightly over engineer it and under tune it. It prefer to have a reliable engine without too much smoke than to squeeze every last bit out of it.

    What engine code is it? If it's a Garrett turbo it'll have an identification plate to tell you the range, whether that's original or not.

    Once you know what fits you may be able to start finding upgrade parts at Darkside, such as this maybe: Darkside Developments - Darkside GTB Turbo Kit for 1.9 8v TDI Engines
