    HEy guys i just wanted to confirm if anyone can help me confirm part numbers for a A3 2.0 TQ 2007 to S3 conversion

    im lookiing at a K04 Turbo though not sure of the number if anyone can pass it on it me ?

    i have a part number but not sure of it : 06F145702C

    S3 injectors : 06F998036F ??


    if anyone can help or on firm the K04 number it would be great


    along with a LOBA pump .....

    LOBA Motorsport 2.0 TFSI High Pressure Fuel Pump Upgrade - GNJ Motorsport


    i was wondering though if i should just fit RS4 injectors instead as im hopping next year to slap on a 3071 or 3076r (when funds permit)

    this forum is cancerous to your bank account :p

    I'm useless with part numbers but there are a few things you need to take into account if you're thinking of a big turbo.

    Firstly,the S3's con rods are tougher than the standard 2.0 rods,and you would need to be thinking of an engine rebuild before going near a GTX3071 or 3076.

    The mapping is injector specific as far as I can remember,so you can't just stick in a set of RS4 injectors,and expect it to work properly either.

    The LP fuel pump would also need to be looked at,as even the S3's pump runs out around 440bhp,and I don't know what the 2.0's pump is good for,but the USP Motorsports uprated pump and maybe auxiliary pump would deal with that.

    USP Motorsports Stage 3 auxiliary Low Pressure Fuel System

    These guys are very quick,very helpful and have loads of useful parts.

    hey Alex cheers for the advice... however i was aware of that hence why going for the K04 for this year as i dont fancy a change of rods and pistons.....

    the build was going to be the following

    Miltek full Turbo back System 3" DP 200 cell cat etc...

    THS FMIC

    LOBA motorsport fuel pump

    B7 RS4 injectors

    K04

    Loba clutch/ flywheel

    .. as for the map.. basically if not mistaken your telling me that when i take it say to REvo or the likes they wouldnt be able to map it and as such would need a custom map ? if so then i might know i a guy that my just well do that for me ... i just dont want to spend the $$$ twice really "too much of it that is.."

    also for some reason S3 injector or pricier then bloody RS4 injectors DOUBLE the price so its a no brainer and double whammy...

    my old 8L S3 had a gtx3076r so im not new to this either :p

    Hi Sevv,

    Just wanted to make sure you were aware of the possible problems,but as you've done it before,you'll be fine!

    I think that giving Revo a call is a very good idea first,just to confirm or deny what I've said,and the guys at USP were very helpful to me when I was doing the BT part of my car.

    It's a matter of allowing for the different fuel flow rates for the two injectors,so it should be simple enough for a good coder.

    Best of luck,and hope you enjoy it!
