It's 1.33L but it's also on a smaller case and port design. It's one of the bigger SR3 compressors used on Miata's and stuff like that.
The compressors are priced separately from the drives and pulleys so don't forget that and shipping is retardedly expensive on individual units. Shipping overseas to an individual isn't so bad, but when you are dealing with a merchant, there are all sorts of fees involved. I think it cost me almost $400 to have a single unit shipped here a couple years ago.
Vortec is now the US distributor for Lysholm so if you want to buy a new one, contact them. You have to be really careful what you get used. Since they are kind of hard to find new and people don't often want to give them up, used prices are typically way higher than they should be. I would be very cautious about anything used.
