Guys,

Here is a pic of the boost pins I removed from various pumps. The 2 on the right are the same as the 1.6GTD but where removed from a peugoet 406 and Ford 1.8L TD. The one on the left was a 2.2L Renault.

I added a link to this thread from the "Star wheels and fuel pins" thread where the fuel pin data is being cataloged.

It looks like the 2.2 Renault has a more aggressive cut cone.

Do you know what the fuel pin numbers are, or know of the years of the vehicles they are from?  Thanks of the info. :)

The 2.2 Renault would have been about 93 / 94.

I found another one today, supposed to be from a Toyota TD, havent got a good look at it yet, but its totally different from the rest. Will still fit in the bore, and is the same length, but from what I noticed at a quick glance, there was a chamfer, not a cone. I'll have a better look at it later.

I'll be in the garage later, I'll check the numbers on the bottom of the pins that I posted earlier.

Personally, I think the spring stiffness has as much to do with the performance gain as anything. I used a 1.6GTD pin (well anything is better than a std. AAZ pin) and got a nice spring that was the same OD yet had a lower resistance. I also machined a new washer under the rubber diaphram with a built in depth stop, rather than using the nylon washer which wasnt centered. The new part will allow travel right to the smallest part of the cone. Would have been easier to just remove the nylon washer but that would have been too easy ! When I finally get this thing down on wheels next week I will know how well the setup is running. The engines been finished for months now, and back in the car but still needed driveshafts.

100mm inner CV jointed shafts are hard to come by ! ended up buying all 4 mk3 GTi CV joints at a cost of £200+VAT, and thats with discount ! The reason - wanted 5x100 wheels on my Mk3 so needed to change the hubs to that of a GTi (or VR6), and calipers. The outer CV splines are different on the GTi and VR6 compared to the rest of the mk3's. TDi's have 100mm inner CV shafts, but they have a cable change box, so the (UK) pass. side shaft is slightly longer than a rod shift GTi or Diesel, and the outer CV's are smaller than the GTi hub ! Just going to swap all 4 1.9D CV's to that of the GTi CV's, should have done it 6 weeks ago instead of messing around in wrecking yards looking 2nd hand shafts just to save £100. learn the hard way of course !

Regards, DM
