    GTW3476 build Octavia Sleeper (mk6 ea888)

    About time I started posting some of my build story (4th and final turbo!)
    FWD Octavia base model 6spd manual - how much more sleeper can you go!
    I've resisted AWD but realise I'll have to go there eventually..

    Going now from Gtx2867r to this monster!
    Turbo comparo picture:


    Will it work? Results in a couple of months..

    This is a total custom build.
    ECU is a standalone inboard Link G4 extreme with stock ecu left to run all the auxiliaries. This was installed 2 turbos ago (gt2871r) and after much trial and error works perfectly.


    More pictures than words to follow in coming days..
    This is probably not going to be my daily driver any longer. I'm looking forward to Trackdays, Hillclimbs and Dynodays!

    Under bonnet shot of last build GTX2867r - since dismantled!

    4" dump pipe now under construction, tacked and ready for welding!


    Engine details so far 25/3/17
    CAW EA888 2.0TSI (ex Jetta with 8000klms)
    Head/Cams stock for now bar Ferrea valve spring kit and removal/delete of fuel pump lobes (talking to Kelford about custom cams/head build in the future)
    Forged Mahle pistons (82.5mm),
    Forged IE rods
    ARP mains bolt kit
    ARP head stud kit
    Bores honed and engine balanced with flywheel on
    Timing chain tensioner - revision MFG# 06F 109 217A
    Rear main seal 2.0TSI solution by Issam Abed (I Abed Industries)
    Fluidampr MFG# 551231
    Integrated Engineering billet oil breather plate to custom catch can install
    Mishimoto 10 row oil cooler kit (purchased a $30 no name oil filter sender sandwich plate to complete the install kit!)
    Ignition coil packs (red) MFG# 06E 905 115E (The coils have been turned 180 degrees and wiring altered and moved to along the fuel rail away from the anticipated exhaust heat!)
    IE DIY inlet manifold with custom runners and flange (direct port injection delete, custom machined direct port bungs with double teflon seals)
    Throttle body GMH 70mm eThrottle
    Intercooler- modified Delata tube & fin universal 600 x 300 x76mm (all 3"pipes, custom aluminium and silicone joiners)

    update edit 26/3/17
    Finding a suitable location for the GTW3476 before the custom SIDEWINDER manifold is built.
    The turbo is too biiig for stock position or high mounting.

    This looks like the spot :-)

    Wow thats a biiig turbo to be running on a 2.0L engine with FWD. Couple of guys on here have run GTX3076 on Golf R Mk6's and made 300kw+ atw but they have the traction to take advantage of the power - even though it doesn't boost until about 3,500-4,000rpm.

    This car of yours will make for one hell of a rolling burnout machine - good luck with it.

    Thanks Lucas
    Yes, long term I'm on the lookout for an S3 or R (manual) write-off to either build as a track/hillclimb car or cannabalise for an AWD conversion..
    Hoping in the meantime to take advantage of the Link G4 with boost limited in the lower gears, failing that there will probably be enough lag off the line haha!

    Mishimoto Oil Cooler Stealth Install

    The Octavia had heaps of room for this install. Painted black to keep the sleeper look behind the grill.

    Big shout out to Mitch @BTM for the custom mount braces which facilitated the inverted stance and fitting of the oil lines.

    Thanks Lucas

    Modifying an Integrated Engineering cast aluminium inlet manifold plenum

    Issue:
    No space for throttle body and intercooler piping.

    Having turned the plenum 180 degrees there was no space for the throttle body and intercooler piping other than remove the driver's side headlamp.
    Headlamp removal was not an option!

    Solution:
    Chop throttle body flange from the plenum, add a 45 degree bend appropriately positioned to allow throttle body and intercooler piping to pass behind and below the driver's side headlamp

    Pictures of pre and post modified plenum including transition process
