bis box/a/cooled box interchange

[126dave]

hi all,this has been addressed elsewhere on here,but i cannot find the posts...........i want to fit my spare bis box to my aircooled,can i just swop bell housings???.........and if so,does anyone have a spare a/cooled bell housing going ?.
the point of this is that i want the higher bis gearing without having to swop diffs etc.......and keep my good a/c box as spare....am i pissing into the wind on this one?

and,i'll need a 1st gear repair kit,any good suggestions of supply???

thanks............

The bellhousings are interchangable, I am waiting for a gasket kit to do this myself. The bis rear mounts are a different shape but the aircooled one bolt in in their place.

Have you tried Axel Gerstl, standard parts are quite cheap and delivery is super quick – tuning bits are loads of money though.

thanks for the info nigel,i thought that the case......i'll try gerstl for the gasket set and gear set,id really like to get a spare bell housing tho,and leave my good box in one peice......lots of knackd boxes out there,hopefully someone on here will feel charitable!!!

Its a good mod if you have the bhp (which it looks like you do). I've posted elsewhere i may have a 650 bellhousing - i can let you know early next week.
