    Tough call Patroni whether you recon the VW or go the Subaru route.
    I was lucky and bought my T3 with the Subaru transplant already done. Its an EJ20 (non turbo) and has been very reliable. The old guy I bought it from did the transplant about 5 years ago. In that time the only mechanicals it needed was oil changes and a new clutch.
    I've only had it for 7 months now and it has'nt used a drop of oil or had any issue's.
    I can only comment from a performance and reliability view and the Subaru certainly ticks the boxes for me.
    The fact you've got Subaru Liberty available is a bonus so the consideration has to be who locally can do the work ( VW or Subaru) and is your gearbox suitable? Mines the 5 speed and for cruising that 5th gear is perfect whereas maybe a 4 speed is not.
    Regards, Kim

    my 2 cents

    air side and dark side are both cool. but at 200ks on the subi donk it is well worth doing head gaskets , timing belt kit and water pump

    I'm in Adelaide also and feel your pain somewhat. South Australia is a bit limited for T3. V and T is a good start. GHR is probably another place you could approach.
    The Subaru conversion I've also thought about if my engine packs in. I think there is a brake conversion in that also, change from drum to disc, but others can confirm that from experience on here for you.
    Is the liberty motor DOHC out of curiosity? That would be alright....

    EJ22 are SOHC. EJ25D are DOHC. EJ251/252/253/201 are SOHC

    Golf motors are common as they are similar to the original diesel.

    Luke at Bayside motors Melbourne now specialises installing Subaru engines in T3 and T2
    He supplies the Subaru engine
    I think he's now charging $6800.00
    $400 for cruise control
    He does a great job !
    0425784367
    I've had my conversion for 12 months and very happy

    I have done my own subie conversion mostly for the learning experience. Knowing everything involved $6800 with a good low km motor is great value

    I assume he uses his own engine mount system and just an adapter plate with replacement flywheel & clutch?

    Does his own wiring harness adaption....

    he told me he worked closely with his engineer when he first started doing the conversions
    he has several T2 Kombis
    His engine mount system is similar to the others ive looked at on the internet
    Uses proven adapter plate etc
    Not sure about the wiring harness !!!
    Mine was approved for NSW rego which cost $620

    Im assuming the 6800 is T3 price only.
    Any idea of bay price?

    The T3 is a fantastic van to drive on the highways and byways of Oz.

    If I had my time over again I'd still go Subi power every time. :cool:

    There are lots of other issues in a T3 that can cause issues such as the sump and coolant bottle and power steering and air conditioning and coolant manifold and exhaust.......I wonder how much of that was included.

    After two Suby conversions in my syncro now - I'm not a fan of the adapter plate ......... the Smallcar custom bell-housing is loads better as it retains the heavier Suby flywheel (keeping the torque levels the same as original) and uses the much smaller and reliable Suby starter - much easier for rear diff-lock access as well.

    The stock Suby sump sits sooo low it will just about snag on everything - worth changing that alone.

    The exhaust clearance is another issue - but if you dont mind dragging your sump around - I suppose the exhaust wont matter either?

    As Scott said, if you don't do clearance modification you run the risk of grounding the sump or exhaust on speed humps steep drives etc ! I've never had the problem with my conversion.

    Yep... I gotta say, the exhaust and sump are the two "high ticket" items my conversion missed out on.
    The old guy that converted mine fabricated the sump from sheet aluminium to look like an upside down " T " to get the right oil capacity.
    Seems to work.. but no cooling fins. For the exhaust he swapped the Subaru headers around to point backwards and somehow cobbled it to the original T3 exhaust. Hey, it sounds like a VW.. just goes a lot quicker... but like the sump would'nt win a beauty competition.

    I had the Suby headers on my donor car and they hang down a long way as in a Subaru they can. The stock sump is enormous.

    The Smallcar sump that Wattie and I have are a fantastic design with cooling fins and great clearance with a well made pick up pipe to make sure the oil system works well.

    Those parts and the engine mount cost a lot but they are really well designed, work well together and give great clearance. My Smallcar exhaust is a work of art!

    Even so I have had it wrapped in exhaust tape to reduce the heat exposure on the Subaru head gaskets on advice from Mike in Newport

    The EG33 6cyl sump is a bit longer and fairly shallow, the lost capacity made up for in the extra side galleries, very clever, however the original Subi sump has a complex baffle system to control oil surge, for me as an ex racer it seemed an important omission also, no magnet included in the design, so as usual I just did my own thing.
    [​IMG]
    Using the mounting flange of the Smallcar sump as a pattern I cut out a baffle plate a fraction smaller than the sump opening then mount this to the windage tray.
    [​IMG]
    To include a magnet I drilled a suitable sized hole into the sump plug and pressed in a Industrial rated Eclipse magnet (very strong)

    However, I think my sump plug is magnetic - maybe after a few complaints they realised they needed it :rolleyes:
