Common questions
Should I fit a GFB DV?:
No, fit a new genuine revision G diverter valve, they can be unreliable, stick or create a delay.
​
Should I do a PCV delete?:
No, keep or fix the stock PCV system, these engines do not behave with PCV deletes.
​
What oil should I use?:
Quantum 5w40 from AKS or Coverdale, originally VW specified 5w30 but you'll have high oil consumption with this.
​
What clutch should I use?
Stock power:
Stock LUK from Eurocarparts/AutoDoc
*Not from eBay due to counterfeits*
​
Stage 1, 2, 2+, hybrid:
TTRS clutch setup: AKS Tuning
*Yes it's direct fit, close to stock pedal feel, holds 450ft-lbs torque*
​
Helix DMF Organic from AKS Tuning is also a good choice if a heavier pedal is suitable for you.
Helix SMF Paddle would be suitable if launching, driving excessively hard or the car spends it's time on track.
​
*Do not use an RTS clutch of any sort*
​
What coilpacks should I buy?:
Genuine R8 coilpacks from the suppliers above, some other suppliers listed above will supply Bosch or NGK coilpacks, you can use these but genuine coilpacks will have a longer lifespan.
