The 1.9L are ~16 ohms.  Be careful you do not order the injectors for the 2.0L aircooled - these measure ~1 ohm.  A VW/Porsche independant shop accidently installed the 2.0L injectors in my 83.5 w/ the 1.9L a few years ago and I went through 2 ECU's due to fried output transistors (the ones on the heat sink) before the shop and I figured it out 2 years later.  83 was the last year of the 2.0L so the mistake is easy to make if you don't specify engines.

The shop suggested the mistake when I called them about the ECU issue and mentioned the injector impedance.   They agreed to replace the injectors and harness connectors (toasted from the extra current) at no charge.  Since the shop owned up to the mistake and make good on the correct injectors two years after the original installation I didn't hold them to the ECU's.  One was used and the original was rebuilt for $100 by a listee so I wasn't in too deep.

I took a quick look at the archives and couldn't find
any specific injector information, so i turn to the
list...

What is the impedance of the injectors in either a 2.1
or 1.9 engine?

and...

What is the nominal flow rate of the same injectors
(supposed to be, anyway...)?

Thanks, and this information is pretty essential to
the new FI system i am building for my van.
