i see you've also done the 1171 cc x 1.7 = 1996 cc's sums.a friend was going to do this with a supercharger from a mini,but never finished it,he probably still has the blower,it's much bigger than a 4agze blower.my idea was always 930 cc x 1.7 = 1590 cc.thats a ma9 motor from a nissan march,it's 4 cylinder,twin cam,16 valve,& super & turbo charged.i was going to put one of them in my 1000,but found out that cams would have put me into the 1600-2000 cc class,& i could never find an ma9,just ma10's.
