Dont think you will get away with running S16 rods and pistons with a 96mm crank as you run them with an 88mm crank to get just under a 2.1 if i remember right.Pretty sure it was matty_rallye on here used a 92mm crank out of a 2.1 xu 406 and 87mm pistons and custom rods ________________________________________ Clicky: [url =http://www.306gti6.com]click here[/url] remove the space between [url & = |

CC=pi × r² × h × 4std gti6 = 1999.0 = pi × 43² × 86 × 4 DW12 crank = 2231.4 = pi × 43² × 96 × 4 |

xud11 92mm crank and 87mm bore is a good combination, you will need custom rods and pistons to make it work and last.s16 rods and pistons will do a 2044 cc on an 88 mm crank, main issue is the wear of most iron blocks and finding good s16 pistons, they're not the lightest of alloy lumps either! the main issue with the s16 rod is that theyre quite short, giving greater thrust angles at mid stroke, ots better to go longer rod shorter piston. most standard rods will be fine for mild hydraulic builds, once you get into the higher rpm solid tappet builds do you need to make sure you have good geometry, you would usually be on lighter pistons by this point anyway so can take them further without issue. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

custom rods and pistons will add many ££ to a build i may as well buy a second hand SC kit  how do the S16 pistons wear i guess the piston skirts get worn ? ive yet to get the pistons and rods out my S16 block nearly there bloody clock changes slow things down |

sc is boring and troublesome, think of the trumpets!pistons wear through use, furthest you can take the s16 ones is 88mm crank as they sit 1mm below deck on 86mm, but compression needs checking as itll change a decent amount from the 10.8 std gti6 with the increased capacity and smaller compression height volume of the s16 bits. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |
