Thanks to everyone. Bloody quick responses to a no nothing question. It all helps and I've passed the gen on to my son.
Not possible to take it back to place that fitted the recon turbos - or more accurately not worth it. Waste of time and space. Seem to be a cowboy outfit.
On behalf of TObe who owns the car - thanks. It gives some good insight and a contact with people who kown what they are talking about.
Thanks again
