Sharkie's TSI Amarok Build

Use the diff lock when accelerating hard and it auto disengages at 80km/h (I think). On light offroading such as dirt tracks it worked really well too. Was a worthwhile upgrade I think.

Thanks mate 👍
PM me when you decide to sell the diff, i'm in melb but i'm sure we can work something out.
With the rear diff have you looked into gear ratios? From what i've found our 2wds run 4.3 and the 4x4 run 4.1.

Presumably lower diff ratio and therefore lower final ratios on 4x4 are better for crawling up obstacles as oppose to the 2wd would have greater benefit from a higher diff ratio, reducing rpm at higher speeds and improving fuel economy or possibly increasing top speeds.

Yeah but as far as I understand it's the other way round, so the 2wd petrol has the highest gearing and therefore shortest gears.

Which is why my stock gearbox is going in for an upgrade. It has a broken 3rd gear synchro anyway, so sending it in for a longer 1st and 2nd second plus all round syncho replacement to make them stronger. Have a specialist gearbox place in Brisbane that does custom builds.

Will be using the donor's gearbox whilst that is being done.

Ah got it, i do remember you writing that now.
So my issue will be trying to find a factory locked petrol diff with the 4.3 ratio or trying to find an aftermarket e-locking or trutrak center to convert my current diff.
There's an ARB air locker center for sale at the minute for $600 but I don't want to have to run a compressor to actuate it etc.

The 2WD diesels also ran the same diff as the TSI, might be a few more of those around.

I will be doing a full build thread on this as somebody may find it useful.

Some teasers though ...

Who can tell me what milestone was just reached? LOL

I don’t know, as I can never seem to see any of your photos

Definitely not my photos; I'd suggest using a different browser/app if photos are a problem for you.

So the 2wd Amarok is 4wd now?
