This all comes down to money, I don't have the funds to buy the 106 on piston heads. I would probably spend the same amount of money it cost to buy the 106 but I won't be doing it all in one lump. I don't earn as much as I did about a year ago when I got made redundant.
I want something different, the fiesta is about 200kg heavier than the Ka, I know there are lots of tuning options for the crossflow engine. I wanted to know if there are the same options for the later engine as I know stuff all about them.
