Mk1 Caddy

The 300tdi pump is a Bosch casting the same as the ECU controlled injector pumps on most vw's. Your 1Z will be pretty much the same as my old AHU motor, which means the center bore of the pump mounting bracket will need machining out to suit the pump, this is something any machine shop can do. It was purely by chance i tried it on my AGR motor and it didn't need modifying at all.

If you google MTDI there is loads of information on it. Some Americans have used old 4 banger cummins pumps, apparently some perkins ones fit too. One lad even put two feeds per cylinder and used the pump from a V8 scania bus on his.

Got the offending item off and coilovers fitted. Not sure I'll stick with the ebay coilovers however, looking into some BC equivalents.



Carl also got a couple of pics on the hillclimb even tho the truck was immensely slow.




And a lovely shot of waiting for the flatbed truck to come, luckily hot dogs and pasties were at hand.

What is the black car behind the caddy in the last photo?

Looks abit like a Chevy Camaro. Circa '68.
I don't think it is though.

Thanks. Thought I recognised it but couldn't quite put my finger on it.

Today I thought I would do a little digging.

The truck wasnt exactly as good and as powerful as I was expecting at RRG. I put this down to bad tune/timing, as there was loads of boost pressure for the truck to play with.

The EGR Is nothing but trouble for any diesel engine and this was no exception... It kind of explains the complete and utter lack of power beyong 3k rpm.

Thats the EGR mixer itself.

And theres the inlet manifold.
The port side of the manifold wasnt much better


In parts, the residue was over 20mm thick. soaking the manifold in neat degreaser, jabbing it with a screwdriver and molesting it with a toothbrush, resulted in a not perfect manifold but a hell of alot better!




Ill make a small replacement adapter to go where the EGR mixer once was this week.

Moving on! I refused to replace the now shagged tire as I despise the wheels that are on the truck with a passion.
After browsing about I decided that I wanted steel wheels, specifically 16" Renault ones. Managed to grab 6 of them at the scrappies for £60. Two of them are slightly different hole pattern but 4 are the same.
4 of these:

Ive ordered some Toyo Proxes T1R's for these to run every day.

The other wheels are from a scenic and are identical in everyway except for the slightly less appealing hole shape. Ive got two of these and theyll have Federal RSR's on them for when I go to the track and such.


About 10 years ago I sprayed the bumper on a friends Astra and the paint company supplied the wrong colour to the code. Ive since had ten tins of Vauxhall Glacia blue sat on my shelf in the garage, I thought I would paint up one of the steels to see if I like it.

It is actually blue but the picture makes it look silver. I think I like it, I can also repainted them at the later date.

The truck didnt have a cooling fan on it for the gathering and it was getting toasty on the hill and in traffic on the way there. I already had the ebay special fan on the shelf and finally got round to fitting it. Only problem now is I have to remake on of the boost pipes as it was in the way.


Finally, just two pics found online of the truck on the hill.



In a bizzle my nizzles.

Been making bits this afternoon.

The wheels needed spigot rings, which are no problem to make, but the front needed spacing by about 10mm which would mean I lost the center bore of the hub as it only protrudes 12mm. So I figured id make some 10mm hub centric spacers with the meganne center bore built into them.

I didn't have any billets kicking around, only some 150x15 aluminium flat bar.
SO! first thing was to grab a mandrel from the store room, clock it up and drill 4 m12 tapped holes @ 4x100 PCD.



Then, the flat bar wouldn't fit into my machine vice, and I really couldn't be arsed getting the machining plate out so I pitched out the holes on the flat bar my hand and drilled them on ye olde Herbert.



NEXT, I put the mandrel into the lathe and clocked up the face, it wasn't ideal as i think it had been beaten with a hammer a few too many times, so I faced it off to be safe.



I then bolted the flat bar to the face of the mandrel and got turning.


Which left me with these.


Taking the mandrel out and sticking soft jaws in, I turned the face to have a 5mm shoulder in the centre at 60mm to suit the renaullt wheels.



Once done, I took out the centres with a 50mm drill.


Then I simply needed to bore the center out to 57.1mm to suit the caddy.


Which left me with these.
They still need Deburring properly and such, I might anodize them tommorow if I can be bothered.


I could have made these faster on the CNC mill, but I had some paying work setup on there, priorities and all that jazz. They only took about 2.5hrs all in anyway.

I also whacked the toyos onto the rims so I can fit them up. Ill need to spray them all some point this weekend tho.


More tomorrow!

Nice work matey

I mean in this top pic.
