Since all the 1.6TD's at my local junk are all stripped of boost pins I'm thinking of using my friends machine shop to modify the the stock 1.9IDI pin.....and i was wondering if anyone has any pics or pointers on where I should start removing material and where to stop....and maybe at what angle???
any comments appreciated!!
thanks

I have done a 1.9 pin with exellent results
First,look on the pin where the feeler has been running,to get an idea of how far down the pin to grind.
If you look at the pin from the side the taper starts to come on then flats off again,i carried the taper on at the same angle for about 12mm to cover the pin stroke, polished the surface up with emery cloth and light oil and voilia fast as hell!!

I like the voilia fast as hell, how has your clutch stood up to all the new power?

the existing slope is there but only runs for a few mm,carry the slope on at the same angle whats there now, for about 12mm

yeah i would just modify a 1.9 pin, infact i would like to pick one up to modify for on my jetta, you can make a longer deeper taper with a 1.9 pin than with a modefied 1.6 pin

ah it helps,but its not a huge power increase
i ground the side that was for more fuel anyways,and left the rest stock,so it can be set back if i want
lean setting
rich setting
i used a dremel with a cutoff wheel to shape it ,then i used some sandpaper on the dremel to polish where the pin rides to clean up the grinding marks

You can modify the boost pin of AAZ with a die grinder and cutter wheel, or you makes news of it at your friend machine shop, it's easy.
I make a couple of them the last summer.

It is an illusion, the slope is same longor as that of origin.
I made a centered machinage, therefore can imports the position of the pin, that changes anything.
These pin will seek the maximum of travel of the feeler finger, the only adjustment is with the adjustment screw in the center of top cover. (increase or decrease fuel under boost)
