Well never made a project thread so thought id get started now its getting interesting :laugh:

my cooper was just a poverty spec with no air con, no traction control and had no chilli pack but just loved the the look, since owning it its been all about looks as there wasnt much point in modifying the cooper engine with the midlands box, i have spent alot but done everything myself keeping prices down

day i picked it up



first mods were eibach 30mm lowering springs, tinted windows, jcw filter and a miltek cat-back! so looked like this...


after having the bonnet vandalised i fitted a cooper s bonnet and sprayed the wheels white :lol:


shortly after the bonnet was sprayed yellow and the wheels were binned for some TD 1.2s with an AP bbk behind them


at this point it looked how i want it and now i want power!!
instead of spending time stripping mine down to standard changing my AP brakes, coilies, wheels, manifold, carbon fibre bits, sorting out selling mine and buying a cooper s which im going to have to spend a grand more to get a decent one im putting a cooper s lump in mine which is alot of work but hopefully will be worth it:thumbup:

the bits i brought were:

ENGINE
FULL SUPERCHARGER
6 SPEED GEAR BOX
ALTERNATOR
STARTER MOTOR
ENGINE LOOM
2 DRIVE SHAFTS
ENGINE MOUNTS
EWS IGNITION BARREL & KEY
ENGINE MANAGEMENT
WATER RADIATOR & FAN
FUEL PUMP.

all this got delivered and i was like kid in a sweet shop untill i noticed the casting on the 6 speed gearbox was cracked underneath :cursing: after ringing the breakers up they agreed to send me another gearbox and chuck me a front slam panel in as compensation :tongue_smilie: so was happy with that!!



the engine has done 55k and after removing the rocker cover couldnt believe how clean the engine oil, rocker arms and the head casting was looked like new :thumbup:

booked the week off work and with some persuading i got my manager to let me use a ramp at work so i started on the monday whipping the cooper lump out, 10 am the car was like this




and in with the S engine and gearbox





the car was up and running but as it was late i left the car till the following day to make sure everything was good



the car drove so well with no probs and the power is awesome

a few months after the GRS intercooler went on along with a 17% kavs pulley making 210bhp on the evolve dyno, and after going santa pod the car set a very respectable 14.5 quarter mile



shortly after, modern mini magazine organized a photoshoot and the car had a 5 page feature in the mag which i was really happy with



and i was voted best cooper by the readers

Nice!

I would change to a GP IC. The recover is a-lot better on the GP than any of the other Inter-coolers as well as being cheaper :)

We need lots of pics of the build :)

awesome project will be well worth it once you finish, has you insurance changed much because of this?
yeh it will increase but its cheaper than insuring a cooper s so it should be worth while as im doing the work myself, plus i could of brought a cooper s with 55k that could have a knackered clutch or other problems least i know my car and its taken me about 10mins to seperate the gearbox from the engine and iv found an oil seal gone and the clutch worn, it would took alot more work doing this with the engine in the car :thumbup1:

You also need the Gearstick and cables, are you leaving the cooper battery at the front ?
yeh iv got gear selector, cables and other bits and peices that arent on that list, i was going to relocate it in the boot didnt think it was possible to fit it under the bonnet on the cooper s? :confused1: :laugh:
