1971 bug mods?
Hi guys. I'm sorry my opening post to the forum was in desperation and demanding but here's a nicer one while the car's getting fixed.
Ok so what I'd like to know is what people think we could do to my girlfriend's bug to improve performance.
Specs:
It's a 1971 1600 Beetle with ball joint rear end (so i think this means it's not a super?). It's got four wheel drum brakes which make me nervous.
It has the (I think) nicer old tail-lights and i've been told that it's interesting because it has elements from the earlier beetles and some from
the later 70s models. The guy who works on it reckons it's just about the perfect match/era for drivability.
I'm getting the work done as a present and I'm not made of cash but I'm willing to spend between 3-4k. I'd like to reward the car as well because
it has worked very hard for me getting me to work and we both love it (probably too much).
Things I think could be improved:
Brakes definitely.
Engine performance.
Suspension/ride height.
(but of course these are all the big ticket and $$$ items)
Paint job (starting to look a bit tired but no rust).
Empi 8s (although really expensive).
What do you guys think?
Sorry I don't have photos yet but the aesthetics aren't what I'm focusing on first anyway.
Thanks for any help guys.

Do u mean it has a swing axle rear end. The front should be ball joint - this should make it a standard beetle, this was the econo version of the
beetle, the super was the more expensive one.
The 4 wheel drums are adequate for street when they are in good tune, they are only scary when they are out of adjustment, need a good bleed, have a
leak in the swing axle which causes the brake shoes to get covered with oil and a few other things. it should be easy to upgrade to late disc brakes,
they should more or less bolt on.
It would probably handle a lot better if you lower it, get a camber compensator, rebuild the front beam, get some bigger sticky tyres. It might even
be worth it to skip swing axle altogether and swap the pan to a semi-trailing arm pan. They handle a lot better.
A budget performance engine can cost about $3-4k, so i reckon your best bet is to just tune the 1600, they can be pretty zippy if they are in good
tune, with the right gearing.
a cheap paint job can cost $3-4k as well
empi 8's cost about a grand for repros.

Hello
At a guess I think you may mean that it is ball joint front and IRS rear? These are a good chassis to work with.
If you've got drums at the front then you can easily upgrade to disks using factory parts, and unless your really pushing them these are more than
ample brakes. Make sure that everything is in new condition and you'll be impressed with how well it does work.
Engine - read around here, then read around http://www.shoptalkforums.com/
then ask around and read more and when your totally confused it may not be an issue any more 
Engines cause more than a few arguments on here - but there are a few good posts on warming up the 1600. Also check out http://www.aircooled.net/gnrlsite/resource/articles/mods.htm
Suspension - well lower is definately the look. Don't go too low if you still want to carve the corners though. New shocks on each corner will
suprise you. And bigger swaybars help. Again read around - there is a heap of info here just put a keyword into the search and hit go!
By the time you've done this you'll have probably used up all your budget and some more - it's really easy to get carried away!!! But heaps of fun
when it finally comes together.
Good luck
Cheers
Jeremy

if ur after a cheap rebuild of the 1600, get it balanced (all from clutch to pulley) and a mild work over of the heads, 3 angle valve job, and mabye a
slightly lumpier reground std cam (it cost us about 2k for a nice rebuild as above of a 1600) and rejet the carb. Also try the disk brake front and
mabye some 15 by 5.5 inch rims with 185 or 195 ish semi perfomance tyres and you won't believe the difference!!!!

I have no sympathy for my car, only the wallet that pays for it!

I agree with Barls - the first two low budget mods to make to a 1600 twin port I would suggest are;
A set of extractors (thunderbird are a good cheapish brand, kadron about the cheapest, both better than standard though).
A twin barrel progressive webber - whether its vacuum secondary or mechanical secondary is not really important. These add a bit of power, and retain
the cars drivability - a good model is 32/36 DGAV (i think). If you still have the stock vacuum / mechanical advance distributor, then keep it - it
will help prevent flat spots that can occur if you go to a 009.
Best of luck and enjoy your bug !

sound like what i had but i found the better version is the one off a lada niva which is a webber copy and has all the adjustment screws at the front
instead of the back as is on the webber you described which was originally on the cortina and escort 2 litre. the new ones that you buy from webber
have the adjustment screws at the front:alien

Sorry I probably should have mentioned that the exhaust isn't standardeither. It's got extractors by the looks of it and then an exhaust bent to the
right with a muffler tucked up under the right rear wheel housing then down to the lower right corner with a flaired end piece with a pretty nice
note. Is this common or is it just plain dangerous? I think it'd have to be changed if we drop the car any?
re: dropping the shell onto a different pan, how much would this typically cost and how difficult is it?
thanks again guys |

sound like whats on my old bug. it not a bad system from the sound of it. lower it at the back is just a matter of adjusting the torsion bars but the
front is a different story. that gets hard and i have no experience with this.

It doesnt cost anything to actually swap a pan other than the purchase of another pan.
the $$$ is in actually building up the pan u are putting it on. 3-4k should build a really sweet pan. but even just getting a used complete IRS pan
should set u back about $500. Replace all the rubbers and mounts, do some other mods and that'd be about $1500 all up for something basic. would
handle a way lot better. And swapping to a late pan means u get discs by default too.

Ok. So we've got her up and running again with a nearly new engine (new heads, internals etc. and a second-hand case). I can't believe the
difference in the engine even though I'm nursing it for the first 1000 kms.
I just managed to stumble into a money tree and find myself in a good situation to give the car some attention, so the plans are back on the drawing
board.:thumb
I think we'll leave the engine alone for a while, but it needs a new carb setup, or at least a replacement for the one that's on it 'cause it's on
the way out.
Going to post some pics when I can get my hands on a digital camera to see what people think.
thanks again for any help. |

Ok so we got a new standard carb and fitted a 009 'cause the old one was on the way out. Car drives heaps better now, with power coming on quicker
and much smoother through the revs.
A couple of weeks ago I had a decent look around the car and found some body dramas:
The rear window leaks at the bottom right hand side and this has caused rust through in the back parcel shelf thing and some rust right through the
pan behind the passenger in the rear footwell.
So i guess there's not much of a decision to be made in regards to the pan because I'm a bit sketchy on keeping the one we've got.
So we're now officially in the hunt for a new pan.
How hard will it be to repair the rust behind the back seat? Has anyone come up against this? |

if you have to go down that avenue
