Had a few folk asking for more info on the intercooler.
The intercooler I fitted is this one:

Additional pipe work was bought from Auto Silicone Hoses, note this image shows enough pipework for 2 cars, so if you're doing only one, then half the quantities.
Apologies if the image quality isn't the best, it looks fuzzy on my phone:
2 of the 45° alloy bends were cut slightly shorter and welded directly to the intercooler:
Once the bumper is off you'll see a piece of ducting, held on by three screws, I removed that, then cut right along the front of that section to remove the brackets for those three screws, and also the small lip. Some of the plastic shrouding also needed trimmed.
Then the intercooler was mocked up and held in place, we made some brackets for the bottom from a nice sheet of 6mm alloy and fixed it to the lower lip of the radiator surround with self tappers, at the top a piece of perforated strip was used, and bolted down through from the top of the crash bar. The only modification to the crash bar was drilling those 2 holes.
I used a 90° alloy bend to come out of the silicone hose from the charge pipe, then linked it to the intercooler with a 45° silicone bend. The 90° alloy one needed cut shorter on the charge pipe side to allow it to sit further in towards the centre of the car. Then, since I had cut off the factory swaging I recreated it using this professional piece of equipment:
It's a plain washer, and an exhaust clamp welded to a pair of vice grips, simple but effective:
Testing on an offcut - factory swage on the right, mine on the left:
On the passenger side of the car a 90° silicone elbow was fitted to the map sensor pipe and connected to another 45° elbow with a 50mm alloy joiner, then connected to the intercooler.
All the silicone hoses were cut slightly shorter to get the fitment right.
Although the fog lamps are in place they are not functional. I cut the lenses from the front of mine and fixed them in place with sikaflex. I wasn't particularly bothered about losing their functionality, because I think people who drive about with their fogs on are idiots, and I've never noticed a great benefit using them in fog anyway. However, I wanted it to look standard at the front.
However, if you wanted them to work, then universal fog light kits are available on eBay, which are quite compact, there is space behind the grilles to accommodate a fog lamp, just not enough for the massive plastic enclosure that is fitted as standard.
Total cost for one car roughly £220.
Hopefully this is some assistance to some people =]
