Sorry for the late reply. Not been on here much recently, busy with doign up the house!
The pulleys and pump were from
www.paceproducts.co.uk. The pump is their off-the shelf gear pump, the pulleys were custom but they should have the drawings on file.
The pulleys are designed to run only the alternator and the oil pump, I used electric water and PAS pumps so you may need to look into that.
Pump mount and sump were custom parts I did but are very specific to my installation, chances are they would not work for anyone else.
Rough prices were:
Pump £700UK
Pulleys £250UK
Pan / Mount £not sure, just labour time really.
Filter head £75UK
Plumbing - Don't forget to cost for this! All those -16 parts are expensive! Probably about £500UK
Not sure what you mean by oil bypass valve, I don't have one in my system.
