Matching a gearbox to a 1916
Guys, In my 67 bug rebuild, I am fitting a 1916.. The g/box is the stock 1300..
Is there any option I can explore to improve on the 1300 box?.. I like the idea of better bottom end torque but I know that the top end will frustrate
without a taller gear option..
Many must have faced the same problem I'm guessing.. I don't want to go to a later bug backend with IRS etc (only because I have no idea what that
entails)
Thanks
Rob

What model 1300 box is it?
An upgrade to the 4.125 diff ratio is nice, but most 1500 trannys have a brass 1/2 fork so keep that in mind.
Also if your tranny is early your axles will be shorter than the 1500.

My choice seems limited.. A 1600 box from an S bug seems the way to go.. That little piece of advice I learned today from Con at VW Village..

Sorry I didn't get back to you so fast.
If you can, I would try the ratios of that 1600 tranny and see if that is
the path you want to take.
You will have to fit your swing axle stuff to the IRS tranny.
Alternatively tou could rebuild your 1300 tranny with a 4.125 diff(or 3.875)
The 1600 tranny will have a bronze fork in 1&2 but it will be fine.

What size tyres are you using? that will affect gearing too. Are you retaining a wide-5 stud pattern up front with the discs? If not (ie you will be
running four-stud wheels and PCD) simply use a 1500 (1968-on) swinger gearbox - bolts in and ratios are taller than the original pre-68. Done that
plenty of times with 1916s :thumb

I wouldn't for these reasons: weaker, 4.3 diff only and limited wheel selection, crook brakes.
you can get later-model four-stud discs for the link pin front end. Match that with a 1968-70 1500 box for a much better result...

Sorry.. Correction.. I was retaining the wide 5s WITH a disc conversion to front beam.. Already picked radars in wide 5 pattern..
VW54 gave good advice when he said to get the resto done.. then fit the 1916 with the 1600s box (adapted).. Once the car is rolling again, I can get
the front beam worked on etc..
Thanks again.. food for thought
