Do you supply both used and rebuilt BNA units?

Yes. Our network supplies the BNA as a tested low-mileage used unit and as a fully reconditioned engine that has been stripped, rebuilt and bench tested. Reconditioned units cost more up front but carry longer warranty cover.

Are the turbo and injectors included with the BNA?

It varies by supplier, so it is worth confirming in writing. Diesel units like the BNA often carry a turbocharger, high-pressure fuel system and particulate filter, and whether those ancillaries are included has a real effect on the price you pay.

Can the BNA be supplied and fitted?

Yes. You can take the BNA supply only if you have your own garage, or choose supply and fit and a local specialist will install and test it for you. Both options are quoted up front with warranty included.
