Cooper S Mk 3 datenblätter

Hello.

I'm going to do engine conversion in my mini 1000, in my country I need some kind of document about "comparison" car that tehy are basicly same car but with some differences, enigne power, brakes, suspension and weights.

I'd like to use Mini Cooper S MK 3 to compare, but I have searched all places, even asked BMW, but nothing.

This forum has some ABE, datenblatt etc, they would be great, but not anything for cooper s.

If someone could help, I will be very gratefull.

Danke!

That kind of document would be great, but there is no cooper mk3, it has to be pretty specific to be acceptable. Even some book or brochure that mentions that both cars are ADO20 would help.

Wikipedia or www page is not acceptable.

Repair manual, brochure, book etc. Scanned pdf, or even picture will help.

Edit:

Anyone have British Leyland: The Cars book? Is there that kind of information?

Or any other book to look?

Thanks!
