Ok this is where I got lost. IIRC the 1.7, 1.8 rods (& crank) are the same. I have a running 1.7 (w. Djet of course) and also have a 1.8 core eng. bad Ljet. Was planning on direct swapping the 1.8 heads and P&C's off of the 1.8 onto the 1.7 and retaining the Djet? Also I have a set of OE 94 (2.0) P&C's that I could use ...... (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) still with the 1.8 heads (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif) Comments? |

you can swap the 1.8 parts to a 1.7, no problem... the 1.8 and 1.7 have the same wristpin locale too you cannot JUST put the 2.0 P&Cs on a 1.7/1.8 crank.... you have to change the rods and crank too... you can you the djet with all of it... you MAY need to get the 2.0 injectors though... and 2.0 brain. |

So why cant you apply the 94's to the 1.7/1.8 rod crank combo?

you can.....sorta, you just have to make sure the pistons for whatever combo you want match the correct rod/crank don't pay too much attention to bore size........... |

I'am surprised no one caught this yet. The 93mm 1.8 cyl, won't fit a 1.7 90mm case, with out the extra cost of opening up the 1.7 case, also the 1.8 head doesn't fit the 90mm cyl. There was a special spacer that centered the 90mm cyl in a 1.8, 2.0 head, but it's not cost effective. (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif) |

no one caught that because you don't have to open a 1.7, or any TIV case until you get to about 103mm pistons... all cases are the same. you have to open 1.7 HEADS for bigger pistons, not the case... but he's using the 1.8 heads, so that is a moot point. |

1.7/1.8 pistons have a different wrist pin offset than the 94mm-96mm 2.0L ones so thats why you can't mix them up!
All type 4 cases are the same spigot opening so 90mm-100mm fit. |

ALL CASES HAVE THE SAME CYLINDER SPIGOT SIZE!!
The 1.7 head ONLY had a smaller register and smaller ports and sometimes even smaller pushrod tube bores. |
