So are all larger pump heads from TDI's? If you are running a 1.6 IDI, you have to stay with a 1.6 or 1.9 IDI camplate, right?

If I were to hypothetically convert my 1.6 IDI into a 1.6 TDI and keep my 1.6TD pump, would going to a TDI rotor and camplate be all that was needed to run TDI injectors?

Can import what engine you convert into a TDI engine, you absolutely need a M-TDI pump, the 1.6TD pump does not work on a 1.6 hypothetic TDI, euhh.. that work, but with very poor power and a lot of smoke, bad idle etc.....

So a tdi camplate and 10mm tdi pump head wouldn't work on a 1.6TD pump?

with some matching parts, yes.

Tintin means the stock TD pump won't work unmodified. You would need a TDI head, cam plate and I think a different or modified control lever and a modified governor wouldn't hurt either.

Awesome. Here's another general question:

Is there any real difference between a TDI pump head and an IDI pump head besides TDI's having a larger range of plunger sizes?

I think the plunger foot is different except maybe on some AAZ pumps.

The bigger foot plunger has been standard at bosch for a few years, the older pump have a small foot plunger and small drive pin.

I found in an old european pump for some application with 11 or 12mm, the plunger foot are small but with a bigger came plate drive pin, if I try to put this plunger in a came plate with small drive pin, that fit but It's tight, I think that the old cummins pump here, are similar.

What sort of mods for the accelerator lever are required? You mean like changing the angle of the levers for the max fuel adjust and the governor lever?

Isn't turning the fuel down sort of the same as picking your foot off the go pedal a little?
