corsa b 1.7TD converted, big block gearbox?

[stemon]

hi all ive fitted a 1.7td from an astra into my corsa and used the standard f13 gearbox, now the gearing is awful , is it possible to fit the astra td gearbox f18 i think? if so what driveshafts ect do i use?

i think the F18 is classed as large spline, so in other words you would need corsa GSI shafts with 2.0 inner cv joints, orr 2.0 conversion shafts and hubs and 2.0 inner and outer cv joints

Thanks for the reply great help where can i get these modified shafts? if thats all thats stopping it fitting i might aswell give it a go

if you have put an f18 on it then its basically the same as doing a 2 litre conversion, you will need either corsa gsi shafts with mk2 cavalier inner cv joints (22 spline) but i would go for big block setup i.e calibra equal length shaft and a mofified vectra shaft with turned down 2 litre hubs or proper conversion shafts
