hi everyone,,recently i was given a 1986 starlet 1.0l, the car comes with 1 previous owner, 52k on the clock with all service history up to 1997. The car has not been moved since 1997 and the interior is mint. The engine sounds very sweet, amazingly after 13 years started second turn of the key with a jump pack. I would like advice what engine i could replace with to make it fast or do i keep the car totataly original as it sounds very well... many thanks
