    I dont have a boost gauge on mine but i think its meant to be 1 bar its running so should be just shy of 15 psi.

    Righty, now the search works i am able to update slightly.

    My fuel filter gave up and started trowing fuel out so i had to pull the car off the road while i ordered the parts up.
    So much for Service history huh! Good job it went so at least i wont have flow problems with a replacement.
    [​IMG]
    It wouldn't undo so i had to modify the clamp
    [​IMG]

    So while it was off road i got jiggy with it.

    Whipped the turbo off after soaking it all weekend in releasing oil ( one for you Lee)
    [​IMG]

    Before physically removing the turbo i thought i would offer up that DP i made.
    [​IMG]
    It was too long and needed trimming so i kinda got carried away while the grinder/welder were accessable
    [​IMG]

    Welds checked by an expert.
    [​IMG]

    Current exit point while i decide whether to stick flexi then cat or flexi then pipe and cat as per next pic

    [​IMG]

    Thats my first thought on positioning, to stick the cat there once the Y splitter has been removed back to a single pipe
    [​IMG]

    My £40 S4 exhaust system, it had to be cut to get it couriered to ne, but no drama, it can be bodged, OOOPS i meant welded.

    Sorted the MAF problem too i think, the GF bought me a MAF housing from a MK3 VR6 Golf ( OBD1)
    [​IMG]

    The good thing is the AJL sensor will fit directly in so positioning is accuarate. The fitment of the MAF to the airbox is different, but i am sure i can "fix" that.
    [​IMG]

    Look at the difference in diameter between AEB/AJL and the VR6
    [​IMG]

    The downside is the silicone TIP wont fit onto it, no matter how much i try.
    so something like this will be required to fit it.

    to accomodate this. Only thing i had to do was widen some of the holes to allow clearence for the bolts to slide in. The M8x35 socket head cap screws are just right with the OEM washers

    Is your old turbo a k03 or a k03's? Dont think i have seen a TQS with a k03's yet.

    I dont have the gear to weld stainless hence using mild steel ( oh and it's much cheaper)

    Ian, its a lowly K03, already checked

    Ian: TQS's dont have K03S', They have exactly the same turbo as an AEB.

    Only B5's with the K03S are the APU and similar DBW engines.

    ye i'm not sure where that came from, it did seem to be regularly touted as the AJL having the larger turbo, but it doesnt!

    Had a busy day doing other stuff so this is as far as i got today, a quick grind and shorten the tail ready for the CAT, then thats good to go. Am awaiting some more pipe ( and cash to afford it,lol) so the exhaust has to go on stop for now.

    After that it's time to remove the turbo( still in place for DP fitment) and start putting the hybrid/ fmic on etc

    I'm getting marks old turbo to fix my no-wastegate.

    Why not just get another turbo from eblag and nail it on?

    Well my old AJL car was chipped to 211bhp and would boost to 15psi so if the turbo is not the factor then there must be other things in play but one thing is for sure if a tuner could get 211bhp out of a AEB setup trust me they would so maybe the later K03's are slightly different.

    well ye, but if its stopping you driving the car surely sticking a 50quid ebay turbo on for a few months is better than taking the bus?

    Righty, been playing again, 3 inch MAF housing with AJL MAF element fitted.

    Note my pikey bracket to secure it
    [​IMG]
    [​IMG]

    I was lucky and happened across a bit pipe i could utilise

    [​IMG]

    Its in, it runs, The TIP aint pretty but i made do

    [​IMG]

    Is it right to have this many bolts and things left over???

    [​IMG]


    Oh and for a laugh, i recorded the car running with downpipe only....

    :icon_thumright: Excellent!.. Looking good to me (apart from the coolant leakage lol).

    Are you running the 3" MAF housing already?

    Bet you can't wait to get the injectors in and the boost cranked up to 30PSI hey?! :jump:

    Leakage ? Spillage due to my dodgy old shakey hands,LMAO

    Yeah Nick said it should be ok, so i will moniter lambda Voltages for now.

    I have had to stop for now, out of cash, need some more migwire and tubing amoung other things so have connected the DP to the TQS exhaust. OMG what a size difference.LOL

    I need the car for a local ish trip so have had to stick it together with gun gum and a reducer thing, as a good mate of mine callled it "pikeytastic"

    [​IMG]

    So no more progress really till after the weekend as we are busy helping some friends out

    That's good to know. I will fit the 3" housing with the turbo from the outset then too.. save me getting a temporary reducer which is a bonus.

    Sorry I forgot about your age. A certain amount of spillage is expected then lol.

    Looking forward to seeing it with the full exhaust.

    I suspect that with that MAF its going to quickly pop a "Adaption Limit Reached - Mixture Weak" code, but we'll see how it goes.

    Keep the N75 unplugged to keep the boost pressure down if your driving it unmapped.

    I'll be on the standard AGU map until it's remapped. To be safe I will disconnect the N75.. good advice :icon_thumright:

    Could always push an insert into the MAF housing to reduce the diameter until mapping I suppose.

    Thats an idea! If you sleeve the MAF down then it should read correctly, Just be a bit tricky getting a "sleeve" that will fit snuggly and not move under load/boost.

    Hopefully the last few bits required to fit the exhaust. Will have a play tomorrow and see what occurs.

    The one is a clamp on to fit the S4 Exhasut to the 3 inch section, and the other is a weld on sleeve to allow me to make the pipe slide over the cat pipework.

    what is 3"? the downpipe?
    I need to join a 3" DP to a 2.75" middle section somehow. may try your reducer pipe trick if there is a big gap.
    WHere did you get it? is it stainless?

    yes, that is what I saw.
    I suspect that the 2.75" pipe will fit inside the DP quite well but it makes the step on the wrong side. Not a huge issue. one more thing to work out

    Right some progress

    TQS system off
    [​IMG]

    Although i prefer the tail pipes on the TQS system over the S4 the dia of the pipework hampers me swapping them.
    TQS
    [​IMG]
    S4 ( i know its not centered yet, its all still loose)
    [​IMG]

    I now wish i had taken more time to get a better exit point for the DP and an entry point into the S4 system as the centre section is kind of "not straight. Some time taken here would have helped me... Next time hey.
    DP, see how close it is to the tunnel? Causes a few issues
    [​IMG]

    The S4 rear with my dodgy @rse CAT on it again, not as centeral as i would like
    [​IMG]

    And the not straight centre section pre grinding...
    [​IMG]

    I am still confident as long as it is airtight, it still has to be better than the TQS system, 3 in DP and centre to 200cell CAT and 65mm S4 exhaust system. I have seen S4s push 300BHP easily on std systems so this should do fine for me at the cost of £120 all in with CAT.

    Have i taken De badging a bit far?
    [​IMG]

    Nope i finally have my plate back, thanks to Lee for looking after it for me.

    [​IMG]

    Will stick the sysytem together and post sound clips in the week for reference

    Any major problems fitting the s4 exhaust, as thinking of buying a £200 ebay one and making it fit mine but yours looks single pipe and the ebay one's are twin all the way through
