Hey guys, this is a cracking forum and I could sit all day enjoying the work done. You guys really know your stuff so any help or comments much appreciated !!!
I have a much loved 2008 140BHP A4 2.0TDi S-line that is facing a complete engine rebuild.
This is personal, so financial common sense is going to be a bit flexible.
I am going to a recommended builder but get the feeling that the he is trying to steer me to use standard kits or a pre "reconditioned" engine. However I want a custom rebuilt engine that can be trusted for the rest of the car life and, hoping to get an extra 60-80 BHP out of it with options for future tweaking.
After a good read of these threads, I cobbled a wish list and am hoping to get your advice on if it is realistic and what are the best brands.
POWER LIMIT
CLUTCH
TURBO
INJECTORS
PREPARATION
GASKETS
BOLTS
RINGS/BEARINGS
OIL

POWER LIMIT
- What is the reasonable power limit on FWD traction?
- I am looking at 200-220 BHP initially if possible.
CLUTCH
- Clutch/flywheel to match (solid or DMF?)
- Is Sachs any good or worth it?
TURBO
- Instead of the 140 turbo, upgrade to a 170+ turbo
- What are good turbos for 200-220 bhp?
- What about the GTB2056VK (less laggy than GTB2260VK)?
INJECTORS
- Instead of the Bosch 140 injectors, upgrade to 170+
- What are good injectors for 200-220 bhp?
PREPARATION
- Skim head/block
- Hone cylinder. Is this required?
GASKETS
- MLS head gasket (Victor Rienz or Erling?)
- What are good gaskets for 200-220 bhp?
BOLTS
- ARP mains studs. Are they good?
- Good Head bolts. What are the best for 220 bhp?
RINGS/BEARINGS
- Piston rings and pins (are oversize pistons required?). I don't want to go crazy with Mahles. Will Standard pistons/rods do for 220 bhp?
- Big end shells
- Mains shells
- Are any other bearings required?
OIL
- Proven oil pump and ancillaries (remembering the balancer issue)
- Oil squirters and ancillaries
- Front and rear crank seals
HEAD
- Valves, guides and seals and cutting in.
- Lifters etc. Do these need to be upgraded?
OTHER KITS
- Timing belt kit
- Water pump and ancillaries (metal impeller e.g. kolbenshmidt one from vwspares)
