Mega build well done.

Lucky having a VW group car, so many parts can be sourced i.e the brakes that just fit!

That is awesome, really great allround car now, you've got the comfort, the noise, the grip with 4wd and now plenty of power, Supercharged R32's kick ass.

So refreshing reading threads like this and not having clowns cracking the same lame "like a golf" jokes.

Yep it does, plans are afoot to make it sound better and release a few more horses, hoping to get a nice round 500!

Thanks, Its certainly handy having a large parts bin to rummage through (runs off to check ETKA for part no for Veyron 16.4 engine)

Done a bit more to the car, started off with sorting something that has bugged me since I got the car. The rear mats were missing the clips which attach them to the floor. I recently got hold of a copy of ETKA. VW’s parts catalogue (the wonders of ebay) this allowed me to search for the parts I needed and order them from the VW dealer.

Missing clips

New clips

New clips fitted


Only a minor thing but I like things to be complete.

Next job was to clean the exhausts as they were starting to look a bit grim.

Before cleaning



To make it a bit easier I decided to remove the exhaust tips from the car



After attacking with a dremel, wire wool & Autosol metal polish




Refitted to the car (sorry about the dirty bumper)



On Monday I dropped the car off to Phirm FX to get the bumper, bonnet & wings resprayed to get rid of all the stone chips and scratches it has picked up over the years.

Poor colour match between bonnet/wing


Newly painted front end





It’s already picked up a stone chip on the 60 mile trip homecensored


Oh well it looked good for all of 10 minfrown

VERY nice, best colour for R32's to be too biggrin the sound of a supercharged V6 is epic so I'm very jealous!

Those rotrex SC kits are decent quality, my brother had one fitted to his 306 GTi-6 and that not only never broke down but it also went like stink! Sounded awesome too wink

Good stuff

Lush mate. Would love to do something like this to mine, but I'm not sure I have the bottle! (Not the driving, more the bills if there were any problems smile) Plus, mech knowledge is fairly basic, so would have to get someone else to do most of the work. Bought a westie to learn on. There's lots of work coming up on mine I think (nearly at 100k) but can't bear to part with it. Figure I will just keep it for a few years. Hopefully they will always sell...

Thanks, sometimes wish I’d kept it standard as where I could go and “play” on some the nice country lanes it’s now a bit too quickwhistle.

It has the standard the half leather half Alcantra Konig seats.

The engine started making some “un-engine like noises” two weeks ago.

Video of sounds: http://www.youtube.com/watch?v=EcrZLEWLtDk&fea...

The first is a metallic ticking (can be heard around 20 secs), the second (loud clicking) at 50 seconds I was able to narrow down to one of the belt idler pulleys for the super charger.

While trying to narrow down the source of the first sound I pulled the coil packs and found thiseek
Coil packs 1-6

Cyl 1

Cyl 4

Cyl 6

Yes that’s water down there
Cyl 6 coil pack, water was dripping out when I pulled it


Apparently this isn’t uncommon, moisture gets trapped down by the plugs and never gets out. The fix is to replace the cam cover gasket as it has seals to prevent moisture getting down to the plugs. Another job for the to do list…. In the meantime I cleaned all the coil packs and replaced the spark plugs (due for replacement anyway)

I decided not to use the car until I could get the engine checked out. While the car was off the road I wanted to tackle another little job. When I almost drowned the car last year, I noticed the connector to the MAF was full of water and needed replacing.

This is what I found when I started stripping the wiring down to replace the connector





Replacement connector and repair wires


Nice shiny gold contacts


New connector built

The rubber grommets supplied with the connector didn’t seal very well, so I filled the back of the connector with hot glue.

It wasn’t until I had cut and stripped the wires that I discovered what a poor state they were in. When I tried to solder the new connector wires to the wiring, this happenedweeping

I have ordered some replacement wire so I can remove the corroded wiring, In the meantime it’s all back together so I can get the car running.


On Thursday the car was loaded onto a trailer and taken to The Phirm to get the idler pulley replaced and the engine noise checked out.


Managed to catch the newly painted bumper on the trailer while loadingirked

On route we thought this was quite impressive

When we arrived at the destination the trip was showing just over 40mpg! not bad as it’s pulling nearly 2,000kg of Golf and trailer. The Golf just about manages 20mpg on it’s ownhehe.
The grumbling pulley was replaced, didn’t get any pictures as the camera was in the car while it was up on the car lift in the workshop.
The engine has been checked over, the feeling is that the noise coming from the top of the engine might be one of the hydraulic tappets sticking a bit as it comes and goes and is only really apparent at 1,100 –1,150 rpm only.
We decided it was safe to drive the car as no damage was being done. On the journey home it clocked up 90,000 miles!


Hopefully over this weekend (assuming it doesn’t rain) I can get the wiring to the MAF replaced.

Oh and I have booked a place on the VW Audi driver track day at Castle Combebounce

Do you know the actual 0-60 and 0-100mph? I'd be very curious to know biggrin

No idea.. last time I tried a 0-60 I kept fluffing the gear change (probably not aggressive enoughpaperbag) one day I’ll put it up the strip to see what I can do…


Made a start on replacing the wiring today, thankfully the corrosion in the wires hasn’t made it back to the original wiring loom.

Nice clean copper to solder to

First new solder joint

After taking that photo I realised I had to break the joint againbanghead to feed the wire through a rubber boot to cover the back of the connector.
I gave up after that, hopefully if it stays dry tomorrow I’ll get it finished.

Nice car, but I think you already know that wink

If you've got an old wire you need to solder to, and it's oxidised (blackened layer on the surface) then untwist it a bit, get a sharp knife and scrape each side of each strand until it's shiny. It will take a few minutes but if you carefully scratch the surface off for a cm or two then twist it back together you'll be able to solder to it.

Also get some glue-filled heatshrink, slide it on before you solder the wires together, then use the shank of the soldering iron to shrink it over the joint. It's great stuff: http://www.maplin.co.uk/heat-shrinkable-tubing-wit...

Got the wiring finished today, new wires connected to the car loom, all joints sealed with hot glue and heat shrink.


MAF connections, joints sealed as above.


The wiring has been sealed with heat shrink and hot glue; I used a 20mm gland boot to cover the back of the connector. The boot is attached to the connector with hot glue, and to ensure a good seal the whole lot was wrapped with self-amalgamating tape.



The completed loom was fed through some convoluted tubing to protect it.


Damage done while loading on to the trailer last weekbanghead (under tray was removed for access to wiring)


Next job is changing the gear box oil, it’s getting a bit hard to get in to gear so hopefully fresh oil will help. Either way it can’t hurt as the gear oil is nearly 10 years old now!

Love this smile
Am looking at rotrex for my E36 at the moment.
As superchargers go i`m pretty sure they are the one to have after speaking to many different people regarding many different kits.
The sound of the R32 along with the supercharger is superb. smile

Gear box sorted, turns out it was just the linkage needing some grease.

Had a good day yesterday at the VW Audi track day at Castle Combe when it eventually dried up! I did 3 track sessions, one in the morning when it was raining heavily, two in the afternoon when it finally dried out.
Video of a few laps from the afternoon.

I was overtaken by nearly everyone and wasn’t particularly quick (lack of confidence). Maybe with a few more track sessions I can build some confidence and I can start doing some of the overtaking, still it was fun.

I wouldn't worry about that. I did my first track day back in march at Outlon in the westie. At the start of the day I was the same (including some stripped out caged Corsa! Felt quite back about that. Towards the end of the day though after the 6th session, I had started to catch up and overtake folk.
