Looking into SVO conversion nozzles. Any thoughts on angle & size for a 2003 Golf TDI 100K miles, automagic trany. Fuel will be preheated to 190*F.

Not much support for SVO conversion nozzles. I'd think one size larger, like a .205, and do everything you can to keep the fuel hot and clean.

IMO, if you are using biodiesel why not stay with it? It's a better fuel than SVO.
Although I know of a few people that have successfully run WVO on the TDI's, I think Bio is much better. WVO does require religious filtering and oil changes along with nozzle and pump maintenance.

One of the problems when jumping up to larger injectors is that WVO users are trying to compensate for the heavier fuel. They use larger nozzles. What ends up happening is the WVO will not properly atomize. The excess oil pyrolizes in the cylinder and homogenizes with the crank oil. That ruins rings, cylinders and can blow turbos from the devalued oil properties.

The best thing to do is go only slightly larger with nozzles and use a larger pump (11mm) with viton seals. That's the other problem with the bio fuels.. leaking seals.

+1 You hear and see too many bad things from WVO users.
