Some of the parts are expensive, but they are plentiful in junk yards for the things you would need. Remember, you wouldn't be needing to buy expensive trim or grilles or interior pieces.
More and more parts are becoming available from the Dealerships (http://www.bmw.com/bmwe/search/index.shtml) and from CNPR (www.justbmws.com) and MAXIMILLIAN (www.mobiletradition.com). You would almost need a set of the Mobile Tradition Parts Manuals, where all the individual parts are listed and noted if available.
The engines are somewhat simple, and can easily be worked by yourself. The bottom ends are the strong link. BMW used a modified version of this block as the basis for their early-80s championship winning F1 engines, which in qualifying trim put out over 1200HP.
As far as the engine rules go:
It's easy to make a 2.3l 2002 engine. I think that it would be hard for officials to tell if you have a E30 (1988-1991) M3 crank in that block though. It would be considered a "stroker" crank, but they couldn't tell, unless you had to provide stock dimensions. With stock pistons, the most compression that flat-tops will give you is 8.3/1.
You could get away with port-matching, and better valves are available in stock sizes.
There are several Weber 2bbl carbs available that work on this car: 32/36 DGV, 38/38 DGAS, and 40/40 DFEV. Flow rates for these carbs ranges from 265cfm (32/36), to 335cfm (40/40).
Ireland Engineering (www.bmw2002.com) and Ground Control (www.ground-control.com/) have coil-over suspension kits. Are you required to use them on the front and rear?
Suspension design: The BMW 2002 suspension lends itself well to small circletrack racing, with it's rear semi-trailing arm design, and front McPherson strut/single control arm design.
I hope this helps,
: HI, I DON'T REALLY KNOW ANYTHING ABOUT THE 2002, OTHER THAN IT FITS IN OUR WHEELBASE RULE AND IT'S A BMW.
: I WAS WONDERING IF THE 2002 WOULD BE A GOOD PICK FOR A MINISTOCK RACE CAR ON A 3/8 MILE PAVED OVAL TRACK, AND HOW EXPENSIVE ARE THEY FOR PARTS AND HOW AVAILABLE ARE THEY, ETC.
: THE BASIC RULES FOR OUR CLASS HERE, ARE ENGINES MAX 2300CC , NO ROLLER CAMS, NO-STROKERS, FLAT-TOPS, NO PORTING AND POLISHING,2BBL CARBS(NO WEBERS),STOCK SIZE VALVES, AND THE REST OF ENGINE OPTIONAL. THE CARS HAVE TO WEIGH POUND PER CC AND YOU CAN GUT OUT MOST OF THE CAR, AND RUN ADJUSTABLE COILOVER TYPE SUSPENSION WITH GOODYEAR RACING TIRES.
: SO WHAT DO YOU THINK, COULD ONE BUILD A COMPETITIVE MINISTOCK FROM A 2002 AND IF SO, WHAT KIND OF ENGINE,PARTS,ETC WOULD BE THE BEST CHOICE TO FIT THE RULES ABOVE. THANKS, ANY INPUT APPRECIATED:)
