Here at we are absolutely delighted to offer for sale, our Sierra Sapphire RS Cosworth 2WD, its a very rare ex race car, that’s registered for the road.

All Sierra RS Cosworth’s are appreciating rapidly in value, our example is pretty unique, it’s a low mileage 1990 2WD, which is ready to be used as a very cool road car, it has a full UK V5 (and new MOT). It was converted as a race car around 20 years ago, and would just need some minor updates to go racing again. As it is, it’s an extreme road car, with the added benefit of being track prepared, its perfect for Track Days (and you wouldn’t need to trailer it there!)

It is really unusual to find a Cosworth race / track car that is still road registered and HPI clear. Our example is in remarkable condition for an ex race car, its race career was short (its owner moved on to a different series). Indeed its only done just over an indicated 1000 miles in the last 15 years.

Our rare Sapphire last raced when it competed in the Classic Touring Car Racing Club series in 2010, it would be interesting to try and research any other aspects of its racing career. It has had a fortune spent on it over the years. It benefitted from a full engine rebuild after its last race season, and has only completed a few hundred road miles since.

It has come to us, from its last racer owner, having been stored inside for over a decade, its underside is remarkably clean and has no signs of having been repaired or plated. It’s a real time warp, its last Silverstone testing scrutineering sticker (from Oct 2010) was still on the dash when we picked it up. 

The history of the iconic RS Cosworths is already well known, and the current rise in the value of Fast Fords, shows no sign of slowing, our low mileage “Cossie” really ticks all the boxes.

Our Sapphire (G573YNX) is presented in Brilliant White, was first registered on 26/2/1990, we have just had it refreshed at prize winning Bushell’s Restorations, for an ex race car, for its age and history it is excellent. It’s mileage is indicated as only 87300. Following its lay up and subsequent refresh our Cosworth has just been for a shake down and given a clean bill of health at our local Cosworth Specialist (Jodie at JD Auto’s - Chatham).

The consortium of “petrol heads” have owned and known the car for over 20 years. It’s engine and drive train was rebuilt at Ice Automotive (Silverstone) about a decade ago (they have confirmed its expensive rebuild), it appears to have only done approx. 1000 miles since, with the following spec:

New Garett T34 Hybrid Turbo (from Owens Developments), with Turbo hanger

Bosch 803 Dark Green injectors

New Radiator

New Airtec RS500 style intercoller

Mocal oil cooler

AP clutch

T5 gearbox rebuilt

Quaife diff

Uprated pistons / rods / cams (spec unknown)

Leda fully adjustable coil overs.

I’m sure there is more, but its specification is comprehensive.

We have not rolling road tested it, but given its spec would assume around 330bhp.

As an ex Race Car, its has been stripped to save weight, the race interior benefits from:

Full welded in Safety Devices roll cage, including side braces and is attached to front and rear suspension turret’s. (It will need re inspecting before being scrutineered for racing).

Plumbed OPM fire extinguisher system, with dash board and front wing activation. (canister will need recharging before being scrutineered for racing).

Electrical / battery isolation kill switch on dash board and front wing (disconnected for the road).

New matching Cobra Monaco Pro seats, on runners.

6 Point Luke harness (drivers side). (will need updating before being scrutineered for racing) and 4 point harness passenger side.

Omex shift light

Quick shift kit

Supplementary boost, coolant temp, oil temp and oil pressure gauges

Our Cossie also come with:

3 sets of wheels:

Recent 225/40/18 BBS split rim replica’s with new Tpyo Proxes tyres (as pictured).

Original Cosworth wheels with 205/50/15 wet weather tyres

Team Dynamic Motor Sport wheels with 205/50/15 Yokohama road legal semi slick track tyres (as seen in the last couple of pictiures)

Set of lowering coil springs

Spare genuine Sapphire Cosworth front bumper with lower plywood front splitter for racing.

Our Cossie, has been used sparingly as a race / track car, having been dry stored for much of the last 2 decades, as such has only been MOT’d in 2005 and 2019, its MOT history supports its low mileage. After its recent recommissioning we have just had it re MOT’d, it passed with no advisories and it does not expire until 15/11/2022.

Like many other RS Cosworths / race cars of the era, it would appear that ours may have been re-shelled and / or had replacement panels. When you check into its history via its VIN number, it would appear to have originally been Magenta (very rare for a 2WD), our example has clearly been Brilliant White for many years, at least since its conversion to a race car approximately 2 decades ago. It comes with a full V5 stating its a white “Sierra RS Cosworth”.

It will have an independent 90+ point pre delivery inspection, for the new owners benefit. It is of course HPI clear and a full HPI report will be available to potential purchasers.

Many thanks for wading through our lengthy description, we believe it’s better to describe our cars fully. It is not in our interest to waste your time or ours with inaccurate descriptions. It does of course have the odd age related imperfection (after all it has been tracked) but for its age and previous use, it really is very cool indeed.

Our Sapphire RS Cosworth, really does tick all the boxes being: super rare, quick, perfect for the track and road, comprehensively track prepared, excellent spec, super rare, rapidly appreciating in value and very, very cool.

Our iconic Cosworth really is a unique opportunity, not just as a rare ex race car, but also as a road and track car that deserves to the driven and enjoyed. Don’t kick yourself in 10 years time that you didn’t buy it, (like I do every day about the 2 Sierra Cosworths I broke to build kit cars!)

Please visit the photographs again (there are many more online at and our terms and conditions also online, as they form part of the description and contact us by calling Peter on 07860691960, to arrange a viewing / test drive by appointment. Any inspection is of course welcome. Part exchange particularly if its quick, big or unusual is a pleasure.
