87mm bore, pistons to suit. Custom rods / pistons to lose some height of the stroke due to the 2mm increase of crank stroke.________________________________________ 2.1 16v 306 Rallye. |

Could be good, but lighter isn't always better though mate I think there might be a good reason why PSA went back to cast iron over alloy |

bigger stroke but shorter con-rod will give lower compression.reason pug went back to cast is because its probably stronger and puts the weight over the driving wheels which is better for traction. anybody watched the latest topgear stunt on a 207gti? they timed it, then stripped it out and timed it again and was faster standard... ________________________________________ 309 GTi6-T |

no I haven't seen that, you have a link?It could be down to the suspension that, probably more roll due to it sitting higher up, |

I'm going down this road at the moment with my engine rebuild. 88mm crank from a XUD9 and 86,5mm forged pistons (1mm lower compression height). End result is circa 2070cc and 11,16 to 1 compression ratio. I'm making the valve pockets 1mm lower in order to have more room to play with timing and bringing the compression down to approximatelly the std ratio. |

I would leave the compression ratio as it is, though it is wise to enlarge the cutouts.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

I was trying to say if its too high you could reduce the size of the rods to get it into a reasonable figure without machining the pistons. ________________________________________ 309 GTi6-T |

Im thinking of building a 2.1 turbo gti6. Iv already got the pistons and rods, 86mm and cr 8.1. If i was to use a 1.9 crank and take 1mm off the crown of the piston what cc will this give and what will the cr be? Thanks Ollie |

the pistons are wossner items, they do have cut out on the crown only and not in the dished part. Would it be safe to take 2mm off them. A friend of mine spoke to brett x longmans builder and he suggested it! Bit worried about takin meat off the pistons. |

depends how deep the valve cutouts are, you'd need to make them deeper too ideally, you will only need to take 1mm off as the stroke is only increased upwards by 1mm.trouble is that they are dished, so it'd be quite an involved process to take the material off accurately. I'd leave it at 86mm tbh, its a lot of messing around for not much benefit as its a Boosted application, if it was N/A and you had flat top pistons it'd be a different matter, or if you were ordering new pistons. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |
