Ultimate Backdating Thread

[timlooney]

Souk,

Did you ever get that group buy on the CTR bumpers?

[KTL]

Now's a good time to replace that trunk weatherstrip if it's at all questionable about sealing decent. Water in the trunk sucks. Ask me how I know.........

Job looks much easier to do with the fenders, bumper and hood out of the way.

Another Franken-911 is in progress. Too cool!

[MotoSook]

Tim, I did not get a bumper... Wish I had..it would have saved me some money later down the road...but the funds went toward the backdate.

Kevin, I'm stripping the whole car! My plan is to have the tub blasted to clean off the paint and new seals everywhere and new headliner. I might have a garage queen in the end....nah! We have enough of those in the area

[Joeaksa]

Nice to see more people doing the backdating on the cars. My 85 is coming along and cannot wait to drive it with the 3.6 and less weight!

Looks like Souk is diving in headfirst, doing a 1-1/2 with a full twist!

You're gonna have a potential garage queen whether you like it or not. Fresh, new, glossy paint can do that to ya. Ah well. A few track events should take care of that issue.

How well does the original seal, 'seal' the trunk when the new hood is fitted? Has anyone any pictures of the area where the latch mechanism would be on a real long hood car but on a conversion? Is there a big gap?

The December issue of 911 & Porsche World has an article on a backdate of a 210Hp '74 Carrera. They did it a bit more full on by welding in the latch panel from a long hood car.



This thread should be re-named 'the ultimate backdating thread'!

Yes! Lets make it the Ultimate Backdate Thread. (than maybe I'll hit a snag and change directions...maybe an Gambella conversion instead )

Chris, can you scan the rest and e-mail it (souk at comcase dot net)? Hi-res is good. Or post it. Maybe Mrs. Claus will give me a 911 World subscription.

Hey 74911s, how did you attach those rear flares? Rivots or screws? What size are they?

[Schrup]

OK, since this is now the offical "Ultimate Back Date Thread", I want to back date my heater. I have heard I'll need a 77 Turbo leftside hot air socket, but I've also heard that the regular early model sockets can be modified to get around the distributor. I would love to find a used one, but don't want to waste the money if it's not going to work properly. I looked up the Turbo part # on PET, came up with part # 930-106-321-01 & entered it on the Pelican Parts search & it comes up with PP #H-106-326-01 at $78.75. I gave Pelican a call I was told this was the part I needed.

The right side shouldn't be an issue, when I did a search for the Turbo rightside part # 911-106-327-01 on Pelican I came up with zip. When I entered the 1972 part # 911-106-327-00 I came up with the socket as a special order item at $55. This part is non refundable.

I just replaced all the hoses on my current heater & hope I can still use some of them. I'm going to have some SSI & a Dansk 2in/2out installed & thought it would be easiest to do the backdate at the same time. Has anyone else that has done this have any words of wisdom? Am I overlooking anything?.

[74911s]

i used small button head bolts. the flares are carbon fiber rs. same width as sc/carrera just shapped a little different.

here is the best pic i have. i also used some vinyl edging to give a more finished look.

Souk,
The article is on it's way in Pdf format. It's kinda big (over 4 Mb) so may take a wee while to download.

I'm planning on backdating my '87 to a '73 RS, using fiberglass or CF fenders/hood/engine lid/ bumpers. Who make the best fitting stuff?

Mark Peterson
'59 & '63 356 Coupes
'66 912 Speedster
'87 911 Coupe

[Jack Olsen]

Name change accomplished. Carry on, backdaters.

Oh, and I got all my body panels from Rennspeed.

[MotoSook]

Thanks for fixing the title Jack!

During my research (way before my CTR-RUF research ) I formed the opinion that steel fenders are best for a street car backdate. The fenders are hard to replicate with f-glass to "perfection." They will not stand up to road/street use as well as the steel fenders. That said, if you choose to buy f-glass fenders, don't expect to just paint and bolt them on. In general, there have been few case of a "perfect" fit on f-glass parts. When you are dealing with fenders and bumpers that have to fit on the front of your car, expect to do the fit and prep work.

For the rears, I would be comfortable with glass or steel flares (although for those guys with the SC's or Carrera's it's a non-issue). Some of the threads and reports indicate that steel or f-glass will bond very nicely and last if done right. I chose steel flares because there is something that makes me and others value properly welded steel flares over bonded f-glass flares. Bonded steel flares, that's another topic (search..I'll add the links later or someone can).

Rennspeed seems to have the best price advertised (well, sort of) for RS rear bumpers. I wish I could get a group buy price for those RS rear bumpers (only piece I need to complete the car).

Wayne? Can you get us a good price on RS rear bumpers?

(Watch, tomorrow the RS rear bumper prices are going to get jacked up... I hope not, cause I can't place an order until after the new year. Damn kids..they don't really need a Christmas do they!)

Some F-glass parts sources GT Racing, MA Shaw, Getty (I already asked Brad at BW and he does not make RS parts) ...etc... I haven't checked Pelican lately to see if Wayne sells F-glass parts such as the RS front and rear bumpers. Have to do that tonight from home.

Note: I can't speak for the quality and fit of any of the aboved mentioned as I have not bought a part from them yet. The important thing is that YOU WILL NOT GET A PERFECT PART! Keep that in mind and you will not be disappointed. If you do get a perfect part, be happy. I can be anal as a Mofo sometimes, but somethings are just the way they are. That's why I have steel fenders and a steel hood.

FWIW in the 911 & Porsche World article they modified the original wings/fenders by adding the extra piece at the wheel arch and the turnsignal housing. Don't think I would be able to do this because I would need early wings to use as a guide and as my SC is my only car, I couldn't have the wings off the car that long. Worth considering though if your circumstances are different.

Thanks for the name change Jack. Makes it easier for searching in future.

[MotoSook]

Wow Chris..I had to go back and read that 911 World page again to understand that poor English (what's this wing business ) in order to appreciate the work Steve Monk did. Seems the hard way to do a backdate.

I haven't seen the e-mail pop in yet, but htank you!

expathk and the rest,

This idea has been rattling around in my head too; backdating a 964 to the long nose look. It seems kinda like a good idea in that you have the coil overs, the good AC, good oil cooling, bigger brakes, etc. and the 3.6 already in the car, all engineered. It seems like with the right choice of parts one could end up with a better performing machine than say taking a '72 T and adding a 3.6. Do you see what I'm getting at? It may be more economical and achieve a better result if one was to start with a 964 and backdate the body. Underneath is better/newer technology with the same basic body as a mid-year car or Carrera.

My thoughts,
Troy

Bring it on, sucka.

Kidding aside, I agree that backdating makes more sense, dollar-wise. Body parts are much cheaper than a 964's suspension, engine and brakes.
