930 Turbo Carrera

Ryan - I've checked the parts cataglogs online (Pelican, etc.) and they show a different wiper part number for '74-75 Carreras vs.'76+ 911s and '76-89 Turbos. Of course none of the catalogs list parts for '75 Turbos but they should have used the same wipers as the '75 Carreras.

The 1976 models may have upgraded to the new wipers but Porsche may not have included the plastic covers over the exposed nuts until the 1977 model year.

 

The 930/50 engine had the same weight as the 930/52. There are some differences bewteen 1975 and 1976 models (interior components, galvanized body, mirrors, etc.).

 

I've weighed my 77 with myself and 1/2 tank of gas, I don't have weight in front of me but I can dig it up. I'll do the same with my 79 and one of my 76's and report back.

Agreed. The changes certainly do not seem to justify such a big spread on the early cars. Can't deny that the differences were there but 232 pounds just seems way off.
.

 

This will be great info. I plan to do this as well but I'll use this for the weigh-in (DIN 70 020 in Porsche Spec books). Fuel weighs a lot so it will make a big difference.

DIN 70 020:
- Charged battery
- Lubricant, coolant and brake fluid
- Standard tool set
- A fuel tank at least 90% full
- Jack and spare wheel

 

My 76 weighs in at 1135 kg. dry.
Aircon and rear window wiper setup has been removed and the car is fitted with lighter Rarly L8 headers/heaterboxes and muffler.
Otherwise the car is stock.

 

Thanks, Phil. Seeing the weights of a similarly optioned and fueled '77 vs. an early '79 would be awesome!

I would use the DIN 70 020 standard vs. dry weight for a weigh-in. The April 1975 Christophorus lists the dry weight of the 1975 Turbo at 2397 lbs but this is without fuel.

 

I cant find any definition of the DIN 70 020 norm with regard to vehicle weight.

But 1135 kg / 2502 lbs. is the dry weight of my car in real life.
It is easy to subtract a full tank of gasoline (80 liters / 21.1 gal and 13,5 liters / 3,56 gal of engine oil)
If you set density of all fluids to 0,8 kg/liter you are very close to reality.

Weight incl. 1 person + approx. ½ tank of fuel + tools + cabin junk and what not, does not make much sense for comparison purposes.

 

Aahh, didn´t see that.
Anyways I don´t have the full std. tool kit

 

And so many are missing this dot on the "original" 75-79 930 I see today. I know it is on at least 3 originals I have owned in the last few years. Amazing so few "experts" miss this important feature that to me as a concours judge should be there if "perfect original". It is delicate to preserve, but isn't that what so many want, a car that was very carefully used. Still present on the 79 pictured with over 30K miles. When I inspect a car, if still there ( and original), it goes a long way for me to think the owner(s) more than likely were very careful when using the car.

I just looked at my old 1975 Carrera 2.7 MFI and my 1976 Carrera 2.7 MFI and indeed they are different. The 1976 has the flat style with plastic covers Thanks for pointing out one other nuance!

I suspect this didn't change cleanly with the model year, and instead was just introduced at some point early during 1976 model year production.

 

You are right the change came with model year 1976, but some of the very first cars were fitted with the 75-style wiper arms. I had one years ago. It's a fact that Porsche did use existing parts stock for new model year cars, or started using new parts at the end of the previous model year, if stock was exhausted to early. PET gives You parts that should be in the car, but there are a lot of cars which left the factory with minor details different. For example, there are 1976 911 with mechanical speedometer for Germany, all official documents tell you that all normal 911 are with electronic speedometer. Japan 911 had always mechanical ones in MY76. Very early cars in my76 did not use all zinc plated sheet metal even on the lower parts of the body. Remaing stock was never wasted.

 

For the chage from 930/50 to /52, that might be the official weight on paper, but the additional parts for air einjection and some other modifications added some weight. Maybe 5 to 10kg.

The official weight of cars was never accurate here in Germany. And it is always for the standard configuration, no extras included.

 

Mine is US no. 520 (very late 76) and it has the old style wiper arms.

 

This is my first post here. I've been hanging around the Pelican turbo forum since its inception. I got this Euro 76 thirty years ago this summer. At the time they hadn't been bringing in Turbos for 4 years so any Turbo for sale was a rare bird. This one was brought in on the onetime EPA deal where it didn't have to meet the phoney baloney requirements that had been slapped on the 80's euro cars.

The car was a 9/10 on paint and 8/10 interior. Problem being the original leather had been a horrid mustard color. Someone had dyed it black but it showed through on several spots I eventually trained to take the black dye I applied over the years. It came with a 150mph speedo which wasn't correct but considering the condition of the car was believable. I changed it over to the correct 180 and had North Hollywood put the miles shown on the new speedo. Also got the big boost gauge that goes in the clock hole.

The first thing I did was buy a Garretson IC. I don't recall what I didn't add but if I let off under full boost in 4th it would buck like a huge surge. I added a K-27 and the Andial fuel enrichment also upgraded to the oil fed chain tensioners.

First rebuild summer of 95 3.2 PC, sc cams, bigger valves ported polished heads etc. Made great power and didn't have the K-26 lag. Several years later in 03 same place, more stuff but with the good powerhaus headers that are still in good shape. Took the micro-fueler and adjustable boost out.

In 05 bare metal respray deleting the rain gutters. It took them a year to paint it and on that fateful day they called July 3rd to tell me the car was finished but the engine was making noises. They had jump started it because the battery was dead then left it outside for 30 min to charge it. Got in and the oil temps were pegged. Got so hot it melted the paint off the inside of the sump plate which plugged oil passages. Ruined cams, rocker arm damage etc. big insurance investigation. I got a free paint job and they split the cost of another rebuild shop of my choice. At the time Imagine auto was a good builder. Shipped the car to KC.

It took them a year to get it right. Main thing was when they put it back in there was an oil leak off the cam tower they could not fix. They had to find another block. Ironically it ended up being 4 digits off the original. Added a Fabspeed muffler. Enlarged fuel heads and anything else you could ask for except efi. Msd ignition. Car ran fantastic. That was summer of 07.

This past summer I replaced the struts to sport Bilstein, all new suspension components, 30mm torsion bar, Tarret sway bar. Lowered the back and thinking about going with the Tarret in the front so it isn't quite where I want it. So as it is the car has 47,500 showing less that 2,000 on the rebuild, 10,000 by me in 30 years, not enough till now. I've put over 1,000 in the last couple of months. The car tracks straight and true. They repainted the top trying to get rid of the minuscule spots along the rain gutter. You can't see it unless you know to look for it.

I have the original bumpers, mirrors, the parts to take off the IC and make the engine look stock. So my question is what is it worth? I know what Haggerty says but realistically?

Love the color and your photo.

Not sure about value but the mods will likely subtract from Hagerty’s price points unless you can find that certain person that really wants all the mods on your car.

 

Forgot about the air injection but it would add weight to the 930/52.

 

For reference, the small wipers have a maximum width of 17mm whereas the larger wipers have a maximum width of 23mm.

It’s interesting that the Japanese market 1976 Turbo, 9306700237 appears to have a mix of attributes - narrow early wiper blades but equipped with the plastic caps over the acorn nuts.

I wonder if Porsche's published numbers are based on the rest-of-world trim, which had fewer options than the U.S. spec cars. For example two heavy options that were standard in U.S., but not RoW were the sunroof and AC. By 1978/79 were these standard in RoW? If so, that would greatly impact the weight.

 

You're correct, AC and sunroof would surely account for some serious pounds. I believe you are right that AC was standard on all US 930's but wasn't it also standard on all RoW 930's since 1977? Sunroofs were always an option on all 930's into the '80's and while a few RoW 930's do not have them, it is rather rare to find a US 930 without one.

I think we would all be surprised at the cumulative weight of the 3 other popular options; sport seats, passenger mirror, and LSD.
.

 

The 23mm wiper arms are later ones, not from 1976. Today You can buy from Porsche only the 74/75 ones and the later ones with a 964 part number, but not the 1976 version. The 1976 version is like the '75 version, only with the addition of the plastic cap.

 

So 1976 versions are 17mm with plastic cap covering the nut? Are the nuts the same size among all the wipers? If so, perhaps they will be easy to swap as I was under the impression you had to remove the hoses and blower unit in the trunk to change out the wiper arms.

 

Bud - A/C was an option on RoW 930's until 1985 and sunroofs were options until 1988.

 

Rich - Thanks. Knew sunroofs became standard at some point in the '80's but wasn't sure on year but I didn't realize AC was an option on the RoW 930's that long.
