    I have an AGU engined A3 1.8T
    It has somesort of remap fitted by a company that i forget the name of now (already done by previous owner).
    It has a Forge DV fitted (alteast i think its a Forge).
    It has a Miltek system (unsure if its just CAT back).

    I have been told by the previous owner that it is around 220BHP (cannot confirm this)

    Anyways, the car has ample power & is quite responsive.

    I just want to know what is next to up the power some more?

    Would i need to consider ways of cooling the intake temperature before i think about more power?

    The car just has the standard SMIC & all OEM pipework.

    Cheers, Pete.

    I cannot see that pulling 220BHP. mine is pritty much the same and its pulling 195 ish!

    for any more power you need a bigger turbo, either:

    1. ko3s, 220 ish
    2. k04 hybrid 260 ish fits standard manifold but needs injectors etc..
    3. k04-023 270/280 need new exhaust manifold, injectors,maf etc,etc
    4. Garrett gt28, up to 300/330 need fcuking loads of stuff looking at £4K
    i am in the process of collecting all the gear for a K04-023, decent gain and all OEM S3 parts to upfit so should be reliabe. will be bout £1500 all fitted with custom remap

    Yeah, it won't be anywhere near 220. The next on your shopping list would be a bigger turbo for power but then that comes with having to change alot of other things.

    so, could i just add some s3 injectors, and get the car RR'd?

    would that increase performance a little?

    I think you'd have to increase the fuel pressure too with a fuel pressure regulator or an uprated pump. What type of fuel pump's do A/S3's use?

    next for horse power IMO are

    k04 direct replacement
    s3 injectors with oem 4 bar fpr
    remap

    you don't need fuel pump the standard is sufficient for that

    optionally at the same time FMIC and samco tip for reliability

    the next stage would be big turbo which would need £4k

    I have heard 440's are not ideal also ie spray pattern,i have also heard that there are some porsche ones that are better suited and i don't think they need spacers either.Theres a few peps on seatcupra.net running aggressive st2 lcr maps and seem to get 280 on standard injectors.Jabba recommended s3 /lcr injectors for ko4 hybrid,its harder to map with 440's apparently.

    If the remap is done correctly then you'll only need a 3 bar fpr.
