I'm fitting P38 style power steering to my s3 109 soon.

Q: Electric pump or belt-driven pump?

What electric pump options are there? I’d assume you’d need a beefy alternator to power such a pump?

What engine do you have? When I fitted p38 PAS to my 88 I also converted to a 200Tdi, so it was easy and simple to just retain the factory Tdi pump setup.

2.25 petrol. There are loads of used electric pumps on fleabay. Reservoir incorporated, so installation dead easy.

I used a Peugeot unit in my RX7. Have no idea of output/requirement the P38 system requires though.
@Dopey has just done it, not sure what pump he used.

Jumping on this thread, I am looking at the same conversion (P38 to a S3 109), but to complicate things I am running Disco 1 axels on leaf springs, and an M57 lump up front.

What would be the neatest solution with this setup?
