How to Convert beetle to IRS?


hey guys, Ryan here, not Danielle, just CBF logging over ;)

but with her car, is there an easy way to change the rear end over to the later IRS type, or are we stuck with the swingarm setup?

mainly because I been looking at different gearbox possibilities, and they all seem to use CV's off the box.
and does anyone know, can you use one of them porsches with the motor up front, and a transaxle out back, well can you use the transaxle out of one of them in a beetle by any chance, if they are 5 speed?

umm thanks lugnuts

I'll check it out.

hopefully it will answer all, in the meantime, anyone else feel free to add.

after reading the lin,, its not so easy apparently, mainly it appears because the shifter goes into the end of the box, and the extra length needs to be cut out of the pan.

although, it still leaves us with the problem of needing IRS rather than swingarm.

The trailing arm pivot points can be welded onto the swingaxle pan, but this requires a lot of work, and i have heard its easy to F up. Also u prob need an engineers report

Other option is to just swap pans and get the disc brake front end as well (if u dont already have one?)

yep.
get a superbug pan and weld your king/ball torsion arm setup to the bulkhead. people tell me its easier to do it this way than try to put the pivot boxes into a swinger....

anyone got a $500 super with good pans/box and 1600 motor??? (not worried bout body)

Best place to start I found was to have a type 3 as a doner car as its easier to cut the mounts of the subframe, let alone getting bigget torsion bars and brakes. And having an i.r.s floor pan to make a jig for the pivot boxes. You might be able to borrow a jig from a vw shop near you if there is any.
The other way that i did the 71 that i've got is to get a strut pan , cut the front off then weld a beam one in place of it. you can still buy these new, better still weld a link pin one on and cut down a ball joint beam to fit (done this to the 67 i've got) Find a semi auto pan , no cutting n welding required except for clutch tube. Enjoy .

alright, give up on the 5 speed fro now :)

did they make beetles at all with the IRS and torsion bar front setup?

we already have disc front end, its just the swingarm rear I dont like.

i tink it was 69 semiautos and 76 beeltes that had the twin link rear and ball torsion fronts.

if you handy with a mig and a grinder and good at finishing off, put your bulkhead on a super pan/backend and be happy.

well, for now, I guess she's just gonna be happy with what its got.

we might have to build another one properly, with ball torsion front and IRS out back. and maybe a fivespeed and all, and this time do it from a bare pan :) so all cutting and welding can be done happily.
