Just general info i've picked up of various people over the years. Never known if it was correct, just assumed it was due to the fact of lots of people. | |

Well you can bore a 1.4 out to the same as whatever you can bore a 1.6 out to, which is about 1650 IIRC. The block is identical, except the 1.4 has a smaller bore as standard, I remember saying this not too long ago. Where ever you got that info from daimo, is wrong. | |

I remember some guy reckon he had his GSi bored out to a 1.8 :lol: Massive debate over it (fair few years ago now). was a debate about it about 2 weeks ago again | |

Pff, i dunno, just information i've gathered over the years. So in reality, you might be able to bore it out more, but from what i've heard from various people, you cant really go much bigger. The block walls get too thin. | |

The heads are the same on the X14/X16 lumps. | |

quote: I only have epc at home so will check in a few hours when I leave work..... If your going to use high comp aftermarket pistons then you'll be better off getting the 1.4 block rebored, as you have it anyway, and will need a rebuild/rebore whether its a 1.4 or 1.6 to start with..... | |

but whats the point in going with new pistons and a rebore if you can pickup a 1600 block cheaper?? | |

Well done. Because valves and ports are the same thing. | |

The valves are the same on the 1.4 and 1.6 16v engines. The 1.6 doesn't respond better than the 1.4, as a percentage increase. | |

i think the valves are larger diameter on 1600 heads?? Which is why it responds better to tuning? | |

Im 99% sure they are the same. I'll double check with epc, but am fairly confident. The heads are interchangeable between the 1.4 and 1.6 blocks. | |

do the 1400 & 1600 blocks not use the same head? | |

Well to rebore it to a 1.6 your going to have to take it back out, take it entirely to bits, pay about £40/60 for a rebore, about £200 for new pistons (unless you can find standard 1.6 pistons used in good nick) then new gaskets to rebuild. | |

just put the 1400 in recently so not an option tbh | |

I don't think it's economic to do it at that size tbh. A replacement 1600 engine would be cheaper. | |

How much does it cost to get engine bored out.... |
