Default Back-dating - Insane idea or might this actually work?

Hello All,

I always wanted a 911 and am contemplating getting one to go with my CD. It is likely going to have to be an air-cooled one (only other 911 I would consider would be a 997.2).

Have only once driven a 911 and it was a 964. Had heard about the infamous tail swings when lifting off in corners. Was going about 100 mph or so, slightly down hill in something I would not even call a corner when 1/4 mile ahead the traffic lights went red and I lifted. What happened next scared the **** out of me (it was not my car).

Because for me lifting off when you go find you go too fast is the natural instinctive/reflex reaction and therefore I would not want to get a 911/930/964.

This tail issue was allegedly solved with the 993 because the rear suspension is totally different. However I dont particularly like the looks of the 993. Nor do I like the prices the good and desirable ones go for these days.

Something older than a 993 if I was to ignore the tail issue would be expensive if it is pristine and you never know how good it really is unless you restored it yourself.

So I am looking for a "project".

To me the best looking air cooled 911s are the 930 / 964 Turbo and/or the 964 3.8 RSR

It seems that the 993 convertibles are the lowest priced 993s around.

So here is the idea.

Get a 993 convertible with issues/damage. Strip it bare remove the rear outside body work and build it up with new 930 rear quarter panels and roof to backdate the 993 convertible to a 930 coupe.

Would that work?

Given the evolution of the air cooled 911s I would expect that the doors, glass and roof would be interchangeable between the various 911 from 1974 to the end of the 993.

But what about the front wings and bonnet can you put 930 or 964 front wings straight onto a 993 or would that not fit? Is the 993 bonnet identical in shape to the one of the earlier 911s?


With all the backdating and resto mods going on, how crazy is this project idea?

Anything is possible with enough money, but a 993's fender and hood height are different than the earlier cars, which is why you never see people backdate 993's.

Also, regarding the tail issue -- learn to drive before you hurt yourself or someone else.

Save the 993s for people who love them.

Personally, I think backdating is bull****, regardless of who does it or whatever generation.

Never is a strong word. https://flatsixes.com/cars/tuned-por...ackdating-993/.

Just one example, have seen others. @dmclassicslimited_ on Instagram has one in flight (they're based in the UK). Not 930's but 993 backdates nonetheless.

I’m with the others - leave the 993’s alone. They don’t backdate well at all. GW and RWB both look cartoonish to me.

I don’t hate backdated in general although I’ve learned that I appreciate factory stuff more. But 993 backdate - yuck.

These are not the cars you’re looking for...

How about you buy the car you like, the 964 or 930, and just learn to drive it properly. It'll likely cost you less in the long run and you'll learn a new skill.

I agree with the others. Too much of the 993 is different from the early cars. Get the 964 or 930 that you want, modify it to your liking & learn to drive it.

The german backdated car is gorgeous... get rid of the plaid interior- yuck!

But do what you want- but your chances of getting a well resolved car are somewhere between slim and none....

The resources? The cost?

+1. Making that pendulum your friend is part of the fun/charm. Suspension mods and tires can also help tame those tendencies.

The driving difference between a 964 and a 993 is not so important , I think it didn’t worth to backdate a 993 . I raced both ‘64 and ´93 and the performance is about the same . So for this season I’m building a 964 rsr clone despite racing my 993 cup , I think the 964 if more fun to drive .....

We only know what you told us about the 964 you drove, which is almost nothing. Consider that these cars are old, and individual examples have wildly varying personalities based on the care, upkeep and modifications they receive. A properly set up 911/912 may surpass the handling limits of a later 964/993 that’s suffered abuse or even just benign neglect. In (almost) all cases the driver is the biggest variable. Maybe the exact specific 964 mentioned above wasn’t ideally suited for what sounds like a very aggressive first drive on public roads in an old Porsche.

It might be wise to spend a little more time behind the wheel of a few examples from various generations before you commit to a 993 backdate.
