I have decided to go stage 2+, the downpipe is organised the only thing left to sort out was th HPFP. KRL from here organised a group buy for the Autotech Internals on the mk5 golf gti forum so picked them up for £246.00 Cheers KRL Hoping to see the internals through the door in a couple of weeks.
I managed to pick a HPFP from ebay for only £100 delivered, it was removed from an S3 engine with only 1000 miles (the engine had suffered from oil starvation as the oil pump chain snapped): link -

I used the Autotech Guide you can find on their website:
http://www.autotech.com/instructions/i127100k.pdfThe autotech guide is pretty good so if you stick to it you cant go wrong, they have listed the tools required in the guide but i will list what i used.
All tools and surfaces were cleaned thouroughly with IPA wipes to remove any soiling and small particles.
Tools:
18mm socket & ratchet
13mm spanner
14mm spanner
17mm spanner
Imperial spanners where used for the larger fittings as most of my larger tools are imperial not metric
15/16" spanner or 24mm
1" 1/4 spanner or 32mm
T25 Security Bit With Screwdriver attachment
Cleaning:
Polythene Sheet To Cover Surface
IPA Wipes
IPA Aerosol
IPA Fluid
Compressor & Air Nozzle
IPA PRODUCTS
AIR NOZZLE
CLEANING SETUP
HPFP BEFORE STRIP
I worked in accordance with the Autotech guide and everything went to plan, the process to strip and clean took about an hour.
The process i used to clean the parts was:
1.Submerge component in IPA for around 60seconds then scrub thoroughly with brush
2.If components has area that are hard to get to use IPA Spray Can to flush the area clean.
3.Use IPA Wipes to finally go over the component and remove any soiling.
4.Using the Air Nozzle, Blow the component to remove any excess IPA.
Once i had carried out the process above the parts were placed on IPA Wipes on a clean surface till i was ready to bag the components.
STRIPPED INTO BITS
PARTS CLEANED AND PLACED ON IPA WIPES READY FOR BAGGING
The Image below shows the internal components split into two bags, i decided to put the larger bulkier components together as i didnt want to cause any metal to metal damage from a heavier components striking a smaller more fragile one. The Spring, Piston etc in one bag and parts from the Relief Valve etc in another bag.
CLEANED AND BAGGED
Once all the internal components were bagged, i re-assembled the housing, screwing all fittings back in loose. Once put together loose the pump body and fittings was bagged.
ALL THESE PARTS WERE INSTALLED TO THE BODY LOOSE.
CLEANED AND ASSEMBLED LOOSE THEN BAGGED TILL AUTOTECH KIT ARRIVES
Ill add pictures of the rebuild once i recieve the Autotech Internals
