Default Decision on rebuilding a RS

Decisions

The last threw years have had some amazing cars in the garage in my opinion, From 1973 RS Porsche to 1965 427 AC cobra not in plastic, 1980 Escort RS 2000, 1974 MK 1 Escort RS 2000 , 1995 4x4 Cavalier Track car, and countless new cars that don’t cut it no more for me I like the old stuff.

So here I am wondering what to do as I have now a 1986 RS Cosworth 3 door and injoy this car more than all the others in fact as I am moving and only have space for one extra car I have sold the rest and kept the RS Cosworth as this car is a real drivers car even above the new ones.

So it is off to the Island of Malta for the RS and a complete refurbishment, But I would like to no your opinion on what would be good and what not to do and advice on parts that you would change and why.
I want to use the car daily once finished for touring as I have planed a tour of Europe with the car visiting as many tracks as possible and some of the know roads . I need a fast road car capable of keeping up with the new cars of today on track and road and to be comfortable for long distances.
I am asking a lot, but I enjoy this car than others to drive and I have looked and tried most and this one for me is the ultimate drivers car.

Many thanks
Zak

NEW fuel pump, a 044(group a) pump would be best.
Your ideas seem sensible, but personally I would ditch the ecu, and run aftermarket of your choice, just don't pay for a big name, launch control might be an advantage ?, with what you're doing.
Add front and rear strut braces, rear brace ideally needs triangulating to the floor, braided brake hoses decent pads, if getting larger wheels get bigger brakes too, could convert the rear discs to vented, 4x4 cossie rear calipers discs fit straight on.
2 VERY common failure points on cossies are the fans and fuel pump, this is due to the age of the wiring on the fuel pump circuit, and the fan circuit was a disaster to start with, fuses/relays/wiring burns out, so these two need rewiring, even for the road, then decide what spec you want the engine, for 420 you don't need to lower the compression ratio at all, I would suggest a T38, roller bearing if you get it, with a BD14 inlet cam, leave the std exhaust cam it is fine, head porting will pay massively well and can gain you everywhere not just at the top end but low down also if done correctly.
