Where can I get used (tuned) 4ag engines? Any good sites in the UK for used car parts? Like ebay or just ad sites. Shops maybe?

I've bought several engine from Fensport over the years so I can recommend them from my experience.

Also they supply RAW with engines so you may as well go direct.

Where do you live? I know of a couple for sale, low milage (60k ish), down south but you'll need to collect. They aren't modified BTW.
