My ultimate one time favourite.The rally version twin turbo V6 did a 0-60 time in 2.1 seconds on gravel..

If anyone has one please please take me out in it...

davyboy

I dont think it was turbo?

All the other ones were, but I just though this was a V6?

The rally version was..Its uses a cut down Rover V8 lump....Not sure if the road going was turbo though.

MikesWagon

Original rally version was 3.0 normally aspirated, only got twin turbos when the likes of Will Gollop got hold of it for Rallycross, then sleeved down to around 2.0 for the regs.

Not being pedantic, just used to clean an ex Malcolm Wilson one when I was a lad.

There was an original N/A road going version for sale near worcester not long back, £30K I think. I heard the engine is the Jag XJ220, but without the turbos, is this true?

imatrukahs

Yeh i heard of one for 30k..sure it had the v6 rover lump though....0-60 4.5secs 110mph top speed 250bhp..

Thought the Rally ones were turbo???They were pumping around 600bhp...

davyboy

So there Ima!!!! :P

the rally ones were 3 litre v6 normally aspirated running about 450bhp it was only rally cross ones that had turbos

davyboy

na na na na na!

brickboy

Pretty sure the original GroupB rally cars were all NA 3 litres. They deliberately went NA for reliability and punch out of corners, rather than constantly having to wring the car's neck

As the other post says, once Group B cars were outlawed, privateers did all sorts to them for rallycross etc

Same basic block & head also graced the Jag XJ220, fact fans. How many other 90s supercars had a motor that could trace its lineage back to a 1960 Buick / Oldsmobile V8?

General Information
The 6R4 Project was first announced in Febuary 1984.
The cars were designed and built under contract by Williams Grand Prix (Formula 1) Engineering.
It started out as 2 wheel drive , later permanent 4 wheel drive was developed.
It was Mid Engined. This is the term used for a car where the engine is located between the axles and usually towards the rear of the car.
It originally had a 250bhp - 12 valve - 3 litre-V6 (A modfied 3.5 litre Rover V8, as fitted in the MGB GT V8)
Later Specifications of the engine increased the power to 400bhp (well over 7 times more powerfull than a standard metro)
Unlike other cars at the time, it was not Turbocharged, but it was Fuel Injected

Davy..the rallycross ones were twin turboed..so right in a way..as the 0-60 on gravel was by Will Gallop..

The engine was a V6 unit which had been derived from the Rover V8 engine which has been seen in numerous vehicles including the MGB. The engine had effectively had two cylinders removed, was fuel-injected, and had been mounted in what would have been the back seats of the Metro model.

A "normal" Rover V8 was cut down to about 3 litres with just six cylinders. It had twelve valves with six carburetters and produced 250bhp. Initially termed the 6R4 engine, (6 cylinders - Rally - 4 wheel drive,) it was later redesigned into the 24 valve V64V, (meaning V6, 4 Valves per cylinder,) at 3 litres. Using the fuel injection system from a Jaguar V12 engine, this out and out sports/racing/rally car could be made to produce 400bhp. In 1987 some were bored out (increased in engine capacity) from 3 to 3.8 litres giving 550bhp; but the most powerful 6R4 engine ever was a 2.3 litre fitted with two turbo chargers. This engine produced some 750bhp. This little MG went from zero to 60mph in just 3 seconds, which is about half the time it has taken you to read this sentence.

As you can see from the pictures, the engine of this car takes up almost all of the spare space in what is an already small car.

davyboy

I know the rally cross ones were turbo charged!!

..........but you did not say that

nah nah

I said the rally version... rallycross same thing.....Plus i said third post down i didnt know if the road version was turboed..

So nerrrrrrrr

6R4 (NA) best sounding rally car this side of Andy Burton's Pug Cossie.

There is a Metro 8R4 kicking around the Nationals, it took part on the Quinton Stages although was not running at a very competitive pace.

I would guess it's a one off that someone has shoe horned a Rover V8 into.

J4MES

The Metro 8R4 is Geoff Cottrill's, I think it's a proper shell but with a V8 in it. It just isn't right when it rumbles past and you're expecting the howl of the V6. I remember it well from when we were parked up in a stage, after retiring from the Quinton this year. He sprayed us with gravel, just after we'd been bitten by ants.
But then again a V8 is considerably cheaper and easier to source than waiting 8 months for Goodmans to build you a proper 6R4 engine, and then writing out a cheque for £18,000.
A chap in our car club runs a 6R4. They are money pits, but they are gorgeous cars.
There was a road going 6R4 for sale in Motoring, sorry Motorsport, News last week. Yours for £26,950 Sir. Clubman trim, 340 miles from new, stored for 15 years, one owner! Never raced or rallied!

And they corner well

There were three competing in the Mewla National this weekend and sounded superb across the Epynt ranges.

Only one finished, Peter Lloyd, but hey he won the rally.

Please see the attached picture



The original development engine for the 6R4 was indeed a cut down 6 cylinder version of the Buick derived Rover V8, single cam per bank, 2 valves per cylinder

The homologated Group B version had a completely different purpose built V6 with twin cams per bank, and 4 valves per cylinder. this was designed in house by David Wood. In single throttle body road version this produced 250bhp. The all singing / dancing works car produced in excess of 400bhp. The highest figure recorded being the car that Tony Pond won the Manx International in, this having 426bhp on Swindon Racing's dyno.All the Metro works group B cars were naturally aspirated.

Will Gollop did fit turbochargers, this was fairly natural as the engine was the basis for the Jaguar XJ220 engine, and it was this technology that Will Gollop made use of.

A friend of mine bought 20 (twenty) 6R4's, including the Manx car, and all the spares from AR Motorsport when the programme came to an end. Tom Walkinshaw (TWR) bought all the engine spares from him at the start of the XJ220 programme. Some of the complete cars interestingly enough were sold to the police in South Africa.

once they had power steering fitted they were quite easy to drive. One was sold to a guy, as his sunday driving car, who had the registration OKP 1 G, apparently he used to get stopped quite regularly by the police for some reason!!

SUNDAY DRIVER

Have never owned one but have been for a cut in the ex.Will Gollop twin turbo rallycross car-on the public road-sitting on a milk crate in the passengers side.Have never experienced anything like it since.

IWatkins

Ex. Will Gollops car now runs in the Hillclimb Championship and is driven and owned by Ken Sims of Malvern.

Car as had its electrics updated and now runs a MoTeC system which basically gave it free power over the old "clockwork" ignition system

To say it is the fastest car I've ever been in would be an understatement, luckily a passanger seat was fitted for the occasion (good job too)

Videos of this car running up Shelsley Walsh hillclimb and being mapped at Enstone airfield (can't do this one on a rolling road) can be seen on the Powerstation website, but scroll down a bit on this page: http://www.powerstation.org.uk/Projects_Page.html

There was a rally-prepared 6R4 developed by Fleming ThermoDynamics in Scotland that used two Sprintex superchargers. Car was owned by Alistair Brearley and co-driven by FTD's Gordon Hastie. Reputedly anything between 750 and 860bhp depending on outside temperature. 0-100 in around 4½ seconds. Awesome.

I seem to remember Car magazine testing a road going 6R4 back in something like 87. It was bright yellow - just a lil distinctive! Someone was converting quite a few and they were up for something like £25k. Anyone have any info?

NLW33

Ok this is taken from the powerstation (cheltenham) website where they have videos of the 750 BHP one they manage (er this was will gollops old metro - like how quick!!)
http://www.powerstation.org.uk/Projects_Page.html
(there are some excellent vids of them testing the motec traction control on an airfield as well as this loon machine in action in hill climbing...frightening!!)

Ex-Will Gollops 6R4
This 6R4 was probably the most powerful 6R4 ever made and certainly the most successful. Its twin turbos produce approximately 750bhp at 2bar boost from its 2.4ltr engine. After winning the European Rallycross Championship two years on the trot, rule changes by the rallycross governing body forced Will Gollop to sell the car. It is now used in the Midlands Hill Climb Championship.
It was brought to Powerstation for a new Engine Management System as the original system was a derivative of the original 6R4 Lucas system. Powerstation fitted a modern MOTEC system which greatly improved the driveability of the engine. Full data logging facilities were also incorporated so detailed analysis of the run up the hill could be carried out.
