They are now doing turnkey solutions, this is probably your best bet, but remember that you will need better brakes and suspension.

To get below 9 secs for 0 - 60 is not too difficult for a 1275. However, a top speed of 110+ as well is rather more dificult as the aerodynamic drag curve is a real problem. Drag increases as the square of the speed and, for a 'brick-shaped' car like the Mini it's a real problem. You would, and here I'm guessing, need around 120 bhp for 110 mph. This is possible, but at the price of a loss of bottom end torque. Thus to pull away would need a very low 1st gear. But with a cammy engine you'll need close ratio gears, so you then have to fit a low diff which will cut off your top speed at, maybe, 100 mph at 6500 rpm.
Now, my 1275 'S' has c.117 bhp, does 0 - 60 in about 7.5, but at 110 mph it would be pulling about 7500 rpm. I never go there and tend to use about 6700 as an absolute maximum which is about 100 mph. But it's just so noisy and harsh at those revs I hardly ever go there except on long straight special stages. I get scared it's going to really blow up!
Alternatively, how about a supercharger?

As Cooperman says, the mini just isn't built for high speeds. Our 1380 sprint car puts out about 140-ish bhp and our data logger shows a 5.9 second 0 to 60 time but a top speed of 'only' 113 mph. And that's pulling in excess of 8,000 rpm so is not something you'd want to make a habit of. And our car has been partially deseamed which probably helps a little.

just stick a 1.6 8v vauxhall engine into it , if you have the ability to change an a-series engine then you can do this. you can buy a kit to help you out .
all for less that 3k easily diy , 100bhp , 5 speed box , fuel injected ..as std

But then, in the opinion of many people, it's not a 'real' Mini any more, it's a hybrid. It all depends on your point of view. There are some purists who will say that the only 'real' Mini is an early 850 with 3.5"x10" wheels and a 'wand' for a gearlever. That's probably going a bit too far, although the early 850 does have a sort of 'period charm' about it (coupled with the water leaks and unreliability!).all for less that 3k easily diy , 100bhp , 5 speed box , fuel injected ..as std

If you must have an A series why not a MG metro turbo engine and box ? Okay only 93 bhp in standard tune, but enough midrange torque to destroy the gearbox. Seriously I know it's been done but I had a metro turbo back in days of old and it was quick enough.
That's a real good answer to the need for power.Frodo69 said:
Wats the best engine conversion for someone who wants sub 9 sec 0 - 60 times, over 110mph and reliability without changing the bodywork to much ? (1.3i mini cooper, late 90's) ...has to be from a company that will fit it themselves along with the neccessary parts. Thanks
O to 60 is not as important as 30 to 80 IN my humble oppinion. Top speed (above about 95) is irrelevant IMHO. Real world it's the ability to overtake on a short stretch of uphill B road, handling, and braking power (and especially wet weather braking) that matter.
