ive just had my carby rb30 converted to injection and as far as im concerned its been well worth it,across the board everything is better about it,we just got back from towing the campertrailer from gawler south ozz to darwin across to broome down to perth and back across to gawler,sat on 100k gettn roughly 20litres to 100k,1100kilo trailer,only trouble i had was breaking down at fitzroy xing as the leccy dizzy shit itself,an easyfix and thats what i get for using second hand parts for the conversion,bought a complete vl commodore for 600 got everything i needed then wrecked the rest and got my 600 back,when it had the carby on it she was fairly gutless towing the trailer..
