Whats the standard compression ratio of a 1.4spi engine? secondly whats the likely compression ratio of said 1.4l engine with a 1.3 head? i hav been searching through threads and Stuart amongst others have said that the compression ratio increases. i along with my brother hav done a head swapped on a 1.4spi that as done jus 10,000k and right of the bat the starter from the old 1.3 engine cant adequately turn the engine (not really important) most importantly i am interested in the comp ratio.. much thanks
