Didn't know which forum to post this to. Hopefully, I can make all answers gathered into a Newbie project/restoration FAQ

I've been into cars for a long time but I'm a newbie at restoration. I'd like my first restoration to be a mini. Don't know much about it though.. I have a ton of questions so here goes:

Types
-I've been hearing a lot about the types of Mini's there are. What's the difference between a Morris Mini, Austin Mini, Rover Mini, and Mini Cooper?

Engine
-I'm planning to build from scratch, get a MkI chassis and Body, get a 1990's Injected Rover Engine for reliability and plug it in. Is this advisable? What kind of mini chassis and body should I get?
-Aside from turbocharging, what other engine modifications can you do to make the car go faster?

Suspension
-Is it advisable to get a replacement Japanese Hi-Lo suspension system? I've seen the original suspension(big rubber ball), it doesn't seem too good.

Brakes
-From what I gathered, the 10 inch disc brakes are favored to the 12 inch discs. Why is this so? Did I get it wrong?

Wheels/ Tires
-Is it just preference or is it better to get 10 inch wheels rather than 12 or 13 inch wheels?

Electricals
-How large of an alternator should be put in? Ill be needing juice for A/C, a substantial sound system, and 5-6 headlights(inspired by the Italian Job!) :wub:

Lights
-Are there HID headlamps and Angel Eyes available for the classic Mini?

I have tons more questions but thats it for now. I hope the experts here can help me out! :grin:

The mini story of the Mini

Written by: Miguel Plano

In 1999, the Mini came to it’s 40th Birthday and was elected as the World’s second car of the Century, one of the greatest designs of Automobile Engineering and becomes one of the classic designs of the twentieth century.

His designer was Sir Alec Issigonis, (1906-1988), born in Smyrna, Turkey, of Greek father and German mother. In 1923, he arrives to England to study Engineering. After a variety of jobs as an Automobile engineer, in 1936 he joins the Morris Motor Design Team (which would later become the BMC) as a Suspension designer. During the Second World War, he commences the design of a compact car, which would become the Morris Minor, which was launched in 1948 with great success. In 1950 Issigonis experiments with a Morris minor prototype with front wheel drive which is discarded and never enters the production line, but later the idea would be used in the Mini. In 1955 Issigonis return to the BMC (British Motor Corporation) after working for three years for Alvis , is nominated chief of Design by Leonard Lord (at the time president of the BMC).

When the Suez Crisis Strikes, Leonard Lord sees the necessity of creating a compact car for the BMC, so in March of 1957 he orders Issigonis to stop all his projects, to focus on the production of a compact car with the only requisite of using already existent parts of the BMC to reduce costs.

The idea was to build a small-dimension vehicle with capacity for four adults and their respective luggage. The formula to achieve such a goal , was a model with independent suspension on all four wheels, transverse engine with the gearbox placed in the carter working as an unit, front wheel drive and, radiator mounted to the left, reducing dimensions notably to a 3.05m width by 1.41m in length, and 1.35m tall. The Engine used, was the veteran A-Series engine, which was previously used in the Austin A37 and the Morris Minor.

After 2 years of gestation, the Morris Mini Minor is shown to the press in August 26th of 1959, creating a great wave within the press and public. They are commercialized as Austin Seven and Morris Mini-Minor (later it would change to Austin Mini and Morris Mini).

It is a car of excellent stability in any terrain, but it’s modest engine of 848cc with 34hp, made it less feasible than many other cars for automobile racing, even though there were those interested in modifying it.

One of them was John Cooper (1923 -2000), who achieved the Formula 1 Championship of Constructors on 1959 & 1960, who was a friend to Issigonis and saw the potential for competence within the Mini. John spoke to Issigonis about the possibility of building a Mini of higher endurance and which could become competitive. Hence commenced the tests, and in October 1961, the Mini Coopers were born. They enter the market as Austin and Morris, with front disc breaks, a 997cc engine, double carburetor, and Modified camshaft and Header. Such combination make 55hp generating a car much more apt for the racing world.

The BMC takes this project so seriously that creates the first Official Team for Rallyes, hires pilots and copilots, among whom the "Flying Finns", Rauno Aaltonen, Timo Mäkinen and Paddy Hopkirk.

By then the Minis where already fast and Success kept knocking their door. But Power was becoming a need to win competences of World recognition, so, in 1963 the engine, besides being improved, is augmented to 1071cc. which provides a higher power of up to 70hp. This version called Cooper S, (the S stands for Special) which Takes Paddy Hopkirk and Henry Liddon to the first place (general) in the Monte Carlo Rallye of 1964.

Rapidly, the Engine of the Cooper S becomes increased to 1275cc further to a 78 hp and in 1965 wins the Monte Carlo Rallye for the second time with Timo Mäkinen on the wheel.

History repeats itself in 1966 when 3 Morris Mini Cooper S accomplished first second and third places in the Monte Carlo Rallye with Mäkinen, Aaltonen and Hopkirk respectively. The French were furious given the fact that the same British Team, took, for the third time in a row, the first place in the prestigious Rally, so, the judges of the event investigated the Minis with immense depth looking for any excuse to disqualify them. After various hours of excruciating search, they found that the frontal front lights and the spotlights used halogen bulbs of simple filament, by that reason, they did not meet with French traffic regulations. The Mini Cooper S, which ended respectively in 1,2,3 were disqualified, as well as Roger Clark in a Ford Lotus-Cortina who had come in fourth. Et Voila! Citroën has won! This disqualification has been one of the soundest scandals of Rally History.

But in 1967, Vengeance was sweet, When Rauno Aaltonen wins again the Monte Carlo Rallye, giving it, it’s third official victory at Monte Carlo. In 1968, 3 Mini Cooper S, came in 3-4-5, given the fact that they find themselves in a most Handicapped situation against the new 911S Porsches and the Ford Escorts.

Minis during the 60s, won more than 25 Rallyes of first line and uncountable National Rallyes, as well as in track racing, where their victories went beyond counting. In this days in the Vintage Racing Category we can see the Minis running just as fast as they did back in the 60s, against Fords, Mustangs, Corvettes, Austin-Healeys, MGs, Triumphs, and other more powerful cars, but Mini, almost always, leads such races.

In October 1967 the MkII is introduced, which had a wider rear screen, a larger front grille and it’s taillights were rectangular. This is the rarest version of the Mini, since two years later, The BMC becomes the BLMC (British Leyland Motor Corporation) and the is shown to the Public the MkIII. The MkIII is an improved version of the MkII, but the most notorious changes occur in the front doors since they already slided the windows downward, now they rolled down, as well as the obvious change of the outward articulations. In 1971, The Coopers, walk out of production. In 1969, there’s an attempt to modernise the mini by creating the Clubman, who’s greatest exponent is the 1275GT. This model, being a real mini is not well received by the public and ceases it’s production by 1980.

In 1980 The BLMC changes it’s name to Austin Morris Group, the Minis are renamed with the name: Austin Mini, and the tires go from 10’ to 12’. In 1988 the name is changed to Rover Group and the Name becomes Rover Mini until production came to an end.

In 1990 the return of the legendary Cooper arrives and with a 1275cc and a 61hp, the fastest Mini since the Cooper S ceased production.

A year later the 1275cc becomes fuel injected and John Cooper sells the Conversion Kit Approved by Rover, which accomplishes an 80hp. The MkIII stays in production until 1996, when Rover develops the MkIV. Amongst the changes are Airbag for the Driver’s seat, Steel Bars for Side-crash protection, but the most significant change was the re-positioning of the Radiator to the front. It’s greatest exponent is the John Cooper S Works with 90hp. More than 5’400.000 Minis were produced in the entire world.

In 1980 there was an Attempt to replace the Mini with the Austin Mini Metro which later became the Rover 100, and although it had relative success, people still kept yearning their Mini. Mini was withdrawn from production in September 18, year 2000, and it’s successor, BMW New MINI Cooper which was launched in 2001, becomes itself a cute car, remaining itself, and never becoming a real Mini, only to bear the name.

In Colombia Minis have made history with Humberto Escobar at the wheel of his Cooper S, whom in 125 races, won 123, and with Adel Kassem and Iván Jiménez amid others, where national champions in a variety of opportunities. The first Mini who raced in Colombia was the one of Humberto Correa in Bogotá in the Ciruito San Diego of 1961. Other enthusiast like Cárlos Uribe, Henry Moore, José R. Ortiz and Jaime Durán drove a Mini too.

7 Years ago The Mini Cords arrived to Colombia, which revived the passion for the mini in our country. The Mini Cord production was extremely small since only 6 Minis where produced a day (in average). They had two basic Models, The Mini Cord SB and the Mini Cord FA, with air conditioning, in 1992 and 1993. After a period of closure of the Facorca Factory, in 1994 there was an attempt to re-open it they had a small number of Mini Cord JC Cooper and Mini Cord JC Cabriolet. For internal problems, the reopen of the factory is cancelled.

In Chile and Uruguay there were small Mini productions with fiberglass body at the end of the 60s. Minis where also produced in Belgium (1972-1981), Australia (1961-1978), In Italy by Innocenti (1965-1975), in Spain by Authi - Automóviles de turismo hispano-Ingleses (Hispanic-English touring cars) (1968-1975), and in South Africa in the 70s.

There are other Mini models that are fewly known within our media like the Riley Elf and the Wolseley Hornet which are a luxury version of the mini launched in 1961, the Pick-up and the Van which are the commercial vehicles, the Moke, a mini multi-utility all-terrain vehicle, the Austin Countryman, Morris Traveler and the Clubman Estate (Estates) and the Mini Clubman which has a radical change is in the front.

The Mini has always inspired a great deal of admiration towards great characters of the world, Niki Lauda drives a Mini daily; Enzo Ferrari, when yearning for fun, went up to the hills in one of his Coopers; Steve McQueen loved his’, John Lennon gave it a spin while being depressed, he had a black Mini); the favorite car of the British Police.

The year 2000 was a sad year for Mini Fans. The 14th of September the last Mini ran out from the Longbridge plant, and on the 24th of December, the Motor world came to a great loss, the death of John Cooper. The Mini dies, John Cooper dies.

What other car, has enjoyed such popularity and has triumphed despite all the factors against it, once, and then again?

as for an injection engien in a mk1... iv not really heard of it as people hu build the mk1's do it for a completly origional car. Though its common to get a later shell, say mk3 onwards, and change a few bits to make it look like an earlier model on the out side. This would include
Rear Lights
Grill
Bootlid
Wheels
Lack of arches

As for the interior, Im presuming you going to b making a custom interior with the ICE and so on.

Engine wise you can do pitty much the same as you can to any other engine. If your building one from there floor then there are larger bore versions available, with cams, heads, uprated box's and so on from all sorts of companies. The can do injection kits too, though im not sure about the reliability of them.


For suspension, the ru ber block or "rubber cones" give very good handeling and the charicteristics of the mini. the std ones are fine for road use and if a stiffer set up is needed then its the dampers which are changed(usually for ajustable types)
for ride hight is where hi-lo's come in. There are many different type, and the non origional ones are alot cheaper(and heavier) The systems are ajustable and the origional ones actually stiffen the suspension.

If you done want to stick with rubber cones then you can get a small coil srping converison but theres are one used really in competition. The still use the hi-lo system for ridehight too.

For ultimate handling then like other cars you can buy coilovers.


Brakes. Now what you have heard probably is that the brakes themselfs are not 10 and 12", thoes are the wheels. But to have discs on a 10" wheel you do need a cirtain caliper and disc combo. whih is usually very expensive(thats if you want to stop) but for 12" wheel and up you can use 8.4" disc which cam on the later minis. You can get servo ass. and non servo mater cylinders and even steel the 4 pot brakes off a metro as they come with vented discs and the 4 pot system means they are the most powerfull OEM system that can be fitted to a mini.


Wheels and tyres wise 10" are looks at as being v. nice indeed but expensive with brakes 12" is a comprimse and 13" can alter the rest of the ssupension geometry and has know to give the car poor feeling(it more complicated than that but wont go itno it now)
As for choosing it really depends on what u want the outcome of the mini to b and look like, and also depends.... as with anything, on money :(


For an alternater the std usually copes but with a large sound system you can use a bigger battery or use a higher ampage alternator. It depends really, we can work it out for you if you can give us the RMS power figure of your planed system(best place to post for that is in the ICE section)


HI's arnt available for the mini and i doubt they ever will be, they are just far too expensive and take up too much room for the gas discharge. Though if you use 100watt rally bulbs in your spots then you will b more than capable of seeing!

Angel eyes are available though look out for the non E marked ones, these are illegal to use and are alot cheaper



keep the questions rollign, we are all willing to guide you/ give opinions
