Guest andy309goodwood Posted February 19, 2006 hi all first off iv done a serch and kinda found what i was looking for but for a differeent crank my Q is im building a hybrid motor and im nearly at the stage of fitting it all together how ever im using a 2.0 L block (xu10) and a crank from an 1.9 gti (xu9) im am asuming all need to use the con rods from the 1.9 to ensure the pistons dont try and punch thro the head and also the crank shaft bearings / end shells will 1.9 gti ones fit in the block ok or will i need to use different ones i know hilgy used 1.9 derv ones for the mi crank will i need these for the gti crank ? all info greatly recived cheers andy Share this post Link to post Share on other sites
Hilgie 16 2 Cars Posted February 19, 2006 Hi Andy, You use the conrods from the 2.0 as well, because the 2.0 pistons are normally 1mm down the bore. Since you have replaced the crank with one with 2mm more stroke this means the pistons will be flush with the deck, just like on a 130bhp 1.9-8V engine. I used the bearings and shells from an XUD9 (which is a castiron block with a 1.9 crank). Share this post Link to post Share on other sites
Guest andy309goodwood Posted February 19, 2006 ahh cool so use the same ones you have for the mi16 crank cheers and thanks for the info on the con rods hoe ever if i use the 1.9 ones would that lower the c/r as im going to be turboing the engine ? cheers again Share this post Link to post Share on other sites
petert 588 Posted February 19, 2006 you can't mix and match pistons and conrods, as the 1.9L Mi pistons have a 22mm pin, whilst the 2.0L pistons have 23mm. Share this post Link to post Share on other sites
Guest andy309goodwood Posted February 21, 2006 (edited) cool right i had a true horror moment last night real hart stopper as i mounted the gti crank all looked well till i tryed to turn it .. it would only turn aprox 40 deg before fowling on the block wall and on one of the piston spray bars the other way once i got my hart restarted i decided it was time to dig out the dremmell (bought the thing about 4 years ago and never used it lol ) 2 hrs later and she was spinning free as a bird all happy and stuff now lol i refitted one of the pistons on the original con rod to the block to see how much clearence it gives with out swapping the con rods for the shorter ones and the piston at tdc rises above the deck of the block by aprox .2 - ..3 of a mm how ever once a compressed head gasket is on there there is about .7 - .8 mm clearance from the head well thats all for now folks if any one is interested i can post pics of where iv had to modify the block to fit the deeper stroke crank ill have to wait till the head turnes up now before i can work out what the C/R will be and wheter or not to drop the C/R in some way cheers guys Edited February 21, 2006 by andy309goodwood Share this post Link to post Share on other sites
