    I have been checking out the archives and the postings on 1.8T 20V engine codes so as to put everything onto a list.
    So far I have 26 different engine codes and the different things I'm noting are the following:
    BHP rating
    Compression ratio
    Vehicle fitment
    Date used
    Cast or Forged crank
    Head port size
    VVT or not VVT
    Internal or External Water pump block
    Turbo used
    Cable throttle or Fly by wire
    Injector size.

    If anyone has this info on any of the 1.8 20V engines, please post it here and I'll add it to the list. I don't mind if things are repeated... it means that I got it right

    If anyone thinks I should include anything else, please put your ideas here too..

    Thanks all

    Mike Ghia

    Updates will be highlighted in blue


    AGN = n/a 125PS internal water pump 058 103 373 X head on it.
    AGN has an 058 103 351 E head

    ARZ engine has an 06A 103 351 D head, so first 3 letters then match the 06A blocks.

    There are no big port 06As that we are aware of.

    AUM head is 06A 103 351 G

    AEB - head is 058 103 353 E (same head as AFY, again poss overseas engine)
    ADR & ABT (o/seas code?) - 058 103 351 G head, same as AGN (barring 06X bottom end), which are all n/a engines
    ARG (early) - 058 103 351 G head
    ARG (late, auto version) - 06A 103 351 D
    APU - 058 103 351 G head
    ANB - 06A 103 351 D, same as late ARG

    - 06A 103 351 D = aged

    Ok,
    Codes now up to 36.

    I have very little info on which engines have cast and forged cranks.

    Also need info on which engines have small port and large port heads.

    Also info on injector size, VVT or not, Internal/external water pump, Compression ratio, throttle cable/fly by wire and Turbo spec.

    Cheers

    AMK:
    C/R - 9.5:1
    VVT = Yes
    Water Pump = Internal
    Turbo = K04
    Throttle = FBW
    Injectors = Large

    APY:
    C/R - 9.5:1

    But saying that, I thought all K04 equipped engines had a 9.0:1 C/R, but that's what ELSA is telling me.

    I checked the AGU, AMK and BAM and all of them were 9.5:1 ?!?!?

    Thanks Lee, I'll look into the inlet manifold idea... it might help a lot of folk.

    Seizure,
    I've just crossed referenced the AMK pistons and head with the BAM and they are the same so I'm presuming that the compression ratio will also be the same at 9.0:1. Thanks for that.

    Chris,
    I have just yesterday installed ETOS on my computer (Skoda, Seat, Audi, VW) parts program on my computer so along with Ekta I should be able to get the other pieces of information I need to complete the spreadsheet... or close to anyway :)
    I'll have an update in the next couple of days and will post it up here.
