Were you on stock or aftermarket pistons?I'd imagine it was 1.4mm or more if it was a repair gasket, maybe even 1.6? part number for that is 209 V4, but servicebox doesn't show the thickness  (I'm sure sandy knows anyway given he recommended!) not cheap compared to off the shelf gaskets!________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

not for a pug, seeing as the heads can;t be skimmed that much the stock are circa 1.2mm or so, repair 1.4 or thereabouts.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

mine is all in one piece and running fine, apart from the pistons as mentioend I did it all myself.Just a PH2 inlet cam, idles like a stock engine! as yet I'm not going to get it remapped, but will try and get it RR'd to make sure its not running lean, I would in future like to get a proper mappable ecu on there like a DTA S40 or similar. not MOT'd or driven any further than ¼ of a mile yet I'm afraid, I have another car as a daily at the moment that I need to sell before I can afford to finish it properly. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

Sorry to drag this up, does anyone have a rough idea how much would need to be machined off the pistons to get enough clearance, ( pockets)Thanks ________________________________________ Do you need a 205 > 306 gti6 plug and go engine loom?

Any thing specific? My pockets are are 1mm deeper than standard (same as welshpugs) and the heads had a 0.25mm skim. I'm currently running 1.3mm of lift at TDC. I'd be fairly confident running 2mm at TDC to be honest but I'm only on standard cams. I don't think you'd want to go much deeper than 1mm on RS pistons. ________________________________________ www.bridgecraftmotorsport.co.uk |

Hi, Spiky was replying to this thread on my behalf.. so thanks to him for that.The situation is: i currently have my engine stripped down and also have acquired a pair of pt81's. Whilst the engine is in pieces i thought it best to get the pistons machined to insure valve/piston clearance. i am currently trying to research (or work out myself) how much needs to be machined. All replies are welcome, thanks |

Thought I'd add the Catcams figures for their fast road cams:4903106 duration @ [0.1mm+cl] 267 / 259° duration @ [1.0mm+cl] 228 / 224° Peak lift 10.95 / 10.40mm Lift @ TDC 1.25 / 1.05mm Seem to have been thought out to work in a standard engine, though without seeing the curve of the profile its hard to compare properly, but they should give similar results to PT81's etc. Though having spoken to Sandy about cams I'd be using Piper or Newmans, he wasn't keen on how catcams design their ramp angles etc with regards to component life as he has had issues withthem. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

I would think they should be ok as long as the head had not been skimmed, or if it had that the seats were cut back.They're the cams that pug1off are using in standard engines for their "195" conversion. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

You can't go much deeper as RFS piston crowns are very thin. ________________________________________ www.bridgecraftmotorsport.co.uk |

How about RFY pistons? Are they thicker? I'm thinking about using the complete RFY bottom end and pocket these pistons. Then slap the RS head on it |

RFY would not need the pockets modifying at all, they are much deeper, however they are a fair bit heavier and the rods are shorter on them meaning a sharper angle mid stroke.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |
