You could try this place for a de-compression plate | |

maybe thinking if the rods shorter it will give a lower crown-deck hieght | |

i think that 1.4xe rods are slightly shorter than 1.6 ones | |

I can supply gaskets, bearings, pistons etc, if wanted to machine a stock type piston. | |

Courtenay had success when they did it years ago. But the stock rods are good for 8k or so, so just get them balanced with rod bolts and some low comp/machined pistons, and if poss a cometic gasket maybe 2.0mm thick. But as sumone wil say either tb it or fit a 20xe/let lol | |

im sure if you can get the propper measurments wiseco(sp) will be able to match up some forged pistons for you.. | |

no such thing as 1.7 pistons as such, not sure if its 80 or 81mm pistons to get to near 1700cc. but 81mm pistons are proper forged jobbies and usually high comp | |

Would i need 1.7 pistons? | |

overbore would be better as blocks will no doubt be too worn ideally for a re-ring. | |

Right well i've bought a c16xe, it's getting rebuilt so going to rebuild with with more power, planning on forced induction. For this i need to lower the compression ratio... What head gasket will i need and what pistons can be used? |
