there would'nt be any point swaping to a 1.4. 1.6 would be the best.i need a engine swap or somthing wanting to upgrade it frmo a 1.2 to maybe 1.4 or 1.6 hmm but cost/time might not be on my side lol
Or get bothExpensive though. A cheaper option is to get a Mantzel or Lexmaul intake. They free up a good amount of horsepower for relatively little cash (£200-300)
