Chester Sportscars Ltd - Upgrade Services

Classic Car Upgrades can be very cost effective, particularly when the vehicle then has an increased value, either to the owner or for Resale.

Fortunately, the earlier Ford Models, Mk 1 & Mk 2 Escorts, Anglias, Cortinas and Mk 1 & Mk 2 Fiestas are increasingly falling into this catagory, particularly where the car has a Classic or Sporting Heritage.

The Upgrade of our Mk1 Mexico, follows our "evaluate and rectify" approach where we assess a substantially sound car and take it through the stages necessary to bring it up to a "good, daily useable, standard " (which for us means quick but safe).

Ford blessed us with a Cheap & Reliable source of modern Single Overhead Cam & Twin Cam 16 valve engines and 5 speed gearboxes, along with a UK Nationwide Spares Organisation and dedicated Specialists who have reproduced what-ever panels and parts have become obsolete.

Couple this with the world wide web and ebay and we have a recipe for obtaining virtually anything off the shelf, fitting it to the car and ending up with a reliable, economic and eye catching Classic.

The photographic record of our Escort Mk1 Mexico Upgrade illustrates our approach to this type of work.

Chester Sportscars’ JPS liveried J15 Sylva Demonstrator fitted with new unmodified Ford 16v Sigma engine and Fiesta gearbox recently made 144 bhp at its’ inaugural Rolling Road session.

The secret’s in the induction and ignition mapping; the combination of a swept alloy inlet manifold, Mikuni 38 mm choke carbs and a 3D ignition setup which responds to engine speed & load, gives a very smooth power curve , peaking at 6,800 rpm and a big increase in lower & mid range torque compared to the standard induction system.

With Ford specifying 99 bhp standard, this increase of 45% over standard is an excellent result and justifies Chester Sportscars in adding the SE Engine Tuning kit onto their range.
