    First off read Prawns thread as he has done the same (albeit with a hybrid K04)

    You only need the VR6 housing, retain the AGU sensor... injector wise you should be looking at at least S3 ones... ME3.8's have iffy injector drivers from what I understand so not happy with some modern injectors but I would imagine early S3 (APY) ones should be ok... you will also need a K04 TIP of some description (Badger5 V2 springs to mind ;P) and a filter... what are the '4 pipes'? you will need the oil drain, oil feed and both water hoses... if you K04 comes with the EGT boss in the hotside you will need to plug that up...

    Thats the oil drain... not tried a K03 oil drain on a K04 so not sure if there will be issues.. the K04 one is longer due to different position and that it has to clear the bevel box on the S3 but as yours is FWD then it 'may' be ok... assuming it will fit on the turbo itself...

    ko3 oil drain will NOT fit on a ko4. Sorry! The fitment is the same at each end, as are the oil and water lines too, but the ko4 sits much higher up and across to one side so the oil drain won't work. That's the pipe you mention with a plate and 2 holes though, so I'm unsure which pipe it is that you don't have!

    Often, you find the cooland return line has been cut, thats the one directly below the turbo in the above pic, although it's not an issue, as you can unpick the crimped joint on the cut rubber hose, and slide a length of silicon hose on there instead to fill in the gap.

    Going back to your first post, you don't need the S3 fuel rail, it's no different to yours. What you do need is some injectors that'll work properly with your ECU.

    For this, you're best off with old school bosch injectors. Current favourites for the AGU / KO4 setup are Saab 346cc red tops - speak to Bobby of Beach Buggy about these, they both have knowledge of them

    Or if you plan to try and take things a bit further, perhaps with a full relentless manifold / dp Combo and aim as high as possible (300bhp has been cracked) then you might be better off with bosch 440 green tops for a little bit more head room.

    I don't think S3 injectors will fit an AGU though? Well they certainly didn't when I did my conversion. I had to go for different Bosch ones (I went overkill and went for green top 440's, but 346 red tops Prawn mentioned would have been by far better).

    Having said that, I was only doing k03s on my AGU, not K04. My mate had 440's on his T3/T4 conversion running 290 BHP, and they were fine for that. So if its 300 your looking for, then 440's might well be worth a shout.

    No. You will still need the bigger injectors. Its just that, in my experience, S3 injectors don't fit the AGU.

    My original AGU injectors maxed out at 208 BHP, then I had to go for bigger ones (as you will obviously have to do), but my 440's were too much even when my k03s maxed out at 240 BHP. (Incidentally, my original AGU intercooler maxed out at 230 BHP too, my car was live mapped on a RR, and I had to quickly arrange these parts as their limits became apparent during tuning. If you haven't already got / considered changing out the intercooler, you might want to before you start your install. I went for upgraded twin SMIC's similar to what S3's run).

    in an ideal world, the 51mm pipes on the turbo revs FMIC are not big enough for a ko4, flow and power will be limited due to the tiny pipe size. need 60-63mm pipes on the FMIC really.

    S3 injectors will physically fit with the use of USRT injector spacers (I've got some I need to flog if you want them), but for mapping the bosch 440's or 346's will work better with your ECU

    Dude. give up on the S3 injectors!

    What FMIC kit do you have with 56mm pipes? The turborevs kit is defintely 51mm OD

    Xs2man, can you explain a bit more about your twin smic setup? How does your piping work as the s3 TB is on the other side so surely it is not a straight swap of s3 oem ic piping. I currently have a larger core turborev smic and it may be a better alternative for me to fit another one to the left if the pipe work is not a pain...

    you can just lift the twin SMIC and inlet manifold setup straight off an S3 and drop it onto the A3 no trouble Sekenzo, although if you've already got an FMIC I wouldn't recommend it, as it's a huge step backwards!
