I have a 1300 swing axle bug and I want to put a 1600 gear box ( which is from an IRS bug ) and engine in it.
The main reason being that I want the better gear ratio for bigger tires, and the extra power would be nice too.
Can this be done ?
Any help would be great, Thanks
INDI
Why change the gearbox the 1300 is a great box for larger tyres.
I have a 1300 beetle swingaxle with 1600 engine as a BAJA and am running 31x10 mud tyres and the gearing is great.
Highway running 4th gear comes in at about 75 - 80 k and pulls real well up hills .
It is also very good around town.
in my humble opinion I would leave the 1300 gearbox and put the 1600 engine which will give you a bit more power and this would be a lot easier that converting a IRS box to fit a swingaxle.

the 1600 box will have higher ratios therefore higher gearing.......the 1300 box would be better for big arse tyres
it can be done. u will have to modify the shock towers for clearance though with the new gearbox.

Thanks mark, That doesnt sound to bad at all.
Do you know what RPM it sits on at around 75 - 80 klm ?
Cheers, Jon.

IRS would be best, but I dont want to have to chop and change stuff to much. if I can help it.
INDI
Swing axle and the new gear box is fine too
INDI
I don't have a tacho yet but at 80 k's you put your foot down and it pulls away.
And this is with an engine we made out of 4 old engines sitting in the back yard
I hope to get a tacho soon if I can find a good secound hand one. so will let you know then

there would be a bit of work to put IRS in a swingaxle beetle

Do you think that the 1600 will fit straight on to the 1300 box ?
INDI
Yes it does the only thing to look at is the flywheel
the flywheel and clutch in my beetle were the small type so I changed it to the 1600 flywheel and clutch. Every thing fit in no trouble we ran it as a beetle for 6 weeks before we BAJA it.

I have been told by a few people that IRS is a better way to go, but by looking at the 2 side by side they arent that different..
Can anyone shed a little on that for me,
🤪
INDI
Well with IRS when you jack up the car for a BAJA the wheels stay straight up and down.
With a swingaxle the wheel will move in at the bottom the more you raise the car.
I have lifted my BAJA about 3 inches and it is not to bad.
the other thing is that there are less moving parts in a swingaxle so less to go wrong .
Apart from that I have driven both types and they drive much ther same.

double jointed IRS pivots not only at the gearbox but at the wheel/hub end of the axles. thus giving you much better handling. and eliminating wheel tuck that happens with swingers.

So Mark
If I have a 1600 and matching irs Box, & a 1300 with swinger box. Can I, using bits of each make a running 1600 with 1300 swing box ?
INDI
I would use the 1600 and the 1300 box just bolt the 1600 in and away you go.
No chopping
