Parts for Porsche from another cars?

[Zendalar]

Ok, time for you to tell which parts you have put to your Porsche from other cars. Or, which parts you could put, if there were no other choice. Here are couple I have seen that are similar in other cars etc...:

Voltage regulator = Made by myself
Breaker points in -71T = Opel Ascona -80
Headlights = Beetle -67

hmm, can't think more right now, but I bet there are more. You tell me For example you could exchange your ignition system directly from a V6 engine, this way costy CDI system would be history.

Brake light switches on master cylender from a VW bug (same part, 1/3 the price per Warren)

I also have the 99° Front oil cooler fan thermoswitch pelican sells. It is a sachs part, which I hear is actually from a BMW.

Porsche makes cars, so do a lot of other people in Germany . Porsche gets many of their little tidbit parts from the same place everyone else does. there are dozens of little OEMs that will supply porsche everything from switches, to wire, to glass, to whateer else they want.

many switches and other electrical parts are sourced from Hella or Bosch... which are the major suppliers for VW/Audi/BMW/Mercedes/Opel etc. you can look up the Hella part number and find the cross reference for it if you e-mail Hella. you might find the same switch in a VW or Audi product, if not Opel or Mercedes.

the fuel injection stuff is all made by Bosch. many of the part numbers can be crossed over to VW/Audi or Mercedes.

the fuel hoses, oil lines,m electrical wires, and othe items are straight-up generic industry standard sizes.

brakes? ATS/Teves has parts that will cross-reference many/most Porsche brakes. so does Girling.

even the drivetrain parts like CVs or bearings were made by Fischer (FAG), Kolbenschmidt, SKF, Meistersatz ,

piston rings, valve springs, and even valves are generic enough that there are dozens of other vehicles out there with similar parts. TRW is a good source for that stuff. so is Goertz and Victor Reinz.

other companies that provide parts are ones like Sachs, Boge, Elring, Febi, Stribel, Mann, Mahle, Nippondenso, VDO, Metal Leve, Lobro, and Continental/Teves. all of those companies have catalogues in which they could cross-reference a Porsche part for you.

i have a pretty extensive cross-reference guide that i compiled at home a long time ago. some day i'm going to put it on the web.

Easy one-rotor from vw bus.

[john walker's workshop]

taillights from a 59 chevy, roof fin 59 cadillac, grille 55 chev. the list goes on.

[not_sure]

How about some more info on the 67 bug headlights. Ive seen these in the vw mags, and they look just like H-4 euros.

Parts interchange....the front Brake Calipers off a 72 911E are the same as VW 411 just have a larger spacer between the caliper halves for the wider rotors. German is german I guess also the front fuel pump from a 1977 Turbo is the same as a Mercedes Benz 280CE pump.

Nearly all parts suppliers use a buyers guide that details which part fits which cars so they can keep a minimum inventory.
Most of the time it won't save any money.
But it does give you more supply sources.

Here is a picture of the -67 beetle lights
Its a perfect fit, only thing that needs to be modified is the part that you attach the light to the car body. (Old picture)

Hello

Beetle headlights ? So the US delivery beetles had the 911 headlights ?

In germany the beetle and the 356 shared the same lights inerta. German beetle drivers used 911 headlights inerta to change to H4.

Opel Ascona breakers might look the same but I suggest not to use them if you have a high rev engine. Better buy the correct ones also to find in other Opel & Mercedes 6 bangers.
The springs on the contacts are to weak to make more then 6000/min revs for sure and then people think the damn CD Ignition has to be replaced by a more "sophisticatet" Volvo V6 unit. This all startet by saving minimal $ !

Costly CDI system ? Shure it was the best aviable in those years and only the Ro 80 and race cars shared the Porsche CD units.

Sachs making oiltemperature switches ? OK VDO belongs to the Sachs Industrialpool ( Not sure now as the big Mannesmann break up caused by the Vodafonedeal maybe seperatet old partners )


Finding Porsche parts is mostly focused on Mercedes and Volkswagen. It is true that other markes also shared some components but thats more on a randomly based way. Porsche also developed many things for other car manufactorers simple using known parts.

BTW if you find some Irmscher Rallye Opel´s look at there brake system.

Goertz ? Graf Goertz is a famous designer Götze is the company.

Meistersatz ?
Metal Leve ?

Obin in need to update my suppliers list.

it's sort of an "interchange" thing, but... a while ago i was talking with a guy that owned a March Indycar. this thing was absolutely gorgeous. he was inbetween sessions, and i was looking the car over.
i took a look at the halfshafts as they were visible over the ground effects. they looked suspiciously familiar.

i asked: "are those special halfshafts or are they from another car?"

surprisingly enough, he said: "actaully, those are Porsche halfshafts from one of their water-cooled cars, i can't remember if it's a 924 or 944."

"are these the original ones?"

he replied: "other than a repacking and rebuilding, the car is totally original."

heh, so it even extends upwards too. there's probably vintage Indycar guys out there that are buying parts from special sources.. when they could be just buying Porsche parts. the interesting part is that they use a different CV boot, but the CVs and halfshafts were identical.

How about MFI? I have a '69 Mercedes coupe with Bosche MFI; maybe these cars are a good source for parts for those with this injection system?

Roland, I meant with the costy CDI system thingie, that you can nowadays get better ones if you have a little time to change the other parts in the ignition system. At least here in Finland the CDI units are very hard to come by, or to find a person who can repair those.

I have heard some people here changing their Bosch CDI system to something else...hmm, i think Zaphod32's car has some general ignition system meant for 6 cylinder cars.

Ups I forgot the Aston Martins, Alfa, BMW and Maseratis. Ferrari race cars also used them mostly in cover boxes or as "back ups".
There was even a "official Bosch" retrofiting set for the Dino cars.
I also had seen them in Lamborghinis and in Monteverdi, Iso Grifos ( Despite both having american engines )

OK the real race CD´s from the 908-936 looked a bit different but all street race cars had the same unit.

How about MFI? I have a '69 Mercedes coupe with Bosche MFI; maybe these cars are a good source for parts for those with this injection system?

FGenerally some parts are shared but the Porsche Pump is a VR6 while the Mercedes has a inline 6. This housing was special made for Porsche but also used later by other tuners ( For eample Mr.May made his Ford Turbos with them )

Roland, I meant with the costy CDI system thingie, that you can nowadays get better ones if you have a little time to change the other parts in the ignition system. At least here in Finland the CDI units are very hard to come by, or to find a person who can repair those.

I know that the early units are damn expensive and as long noone will remanufactor the special condensor some boxes can´t be renewd untill they become very sacre in some years. Not to forget all the other owners from Masertis, Alfa a.s.o are also hit on it.

Porsche has a very simple solution as you can upgrade to the newer SC ignition. You just need someone who is able to change the gear drive on the distributor to let it run the original direction and you have some trouble when you have to remove the cap.
Also you can use a other pickup that will fit the original 184 distributor housing.
I was trying to find something usefull for the Marelli distributors and fiddled a Marelli pick up in there ( mainly to sale them to 914/6 owners ) but then Marelli stoped producing the pick up and also stoped producing the Cap. The reason; no one will buy parts from a car older then 10 years ( hey Marelli is owned by Fiat and there cars hardly survive 5 years, except the High price modells with a private mechanic taking care ).

Bosch also had a general 6 cylinder retrofit solution in the 80´s but this also runed out stock. This system used a high performance coil like the Mercedes setup and later DME cars.

You can adopt nearly every Bosch ignition into a Porsche. The problem is the early cars need the high power spark to run well. The later 2,7 on are very uncritical except the Turbos.

So for a normal used car a "normal" ignition will work satisfying.

The strange thing with aftermarked solutions is that the mechaniks allways seem to throw the parts in and hack up the original wireloom to find a way trough that "tupid"shielding. A also investet to much time in troubleshooting unknown Ignition modules without any documentation and no manufactorer support in germany ( This was back then when internet was in childshoes and Jacobs needed 6 months and 20$ to ship some sheets they sayed nothing except that they make the best ignition off the world and have million satisfied costumers ). I also loved those srange Silicone Maximum Force igniton wires ( Blue Max ! ) adding more troublespots then worth the "pgrade".

The best was a 928 who had "electric coded & supraleading ignition wires". To help troubleshooting i installed new wires and the problem was solved. the guy came by and made a testdrive and was impressed how smoth the car runned and how responsive. Now he thought it was a injecton problem after he installed the best wires on the marked. The truth was he had the wrong spark plugs and disributorcap was maybe still the one coming from the factory. After testdriving I reversed his "blessed" wires and the car still runed fine but not a hair better.

I love most things from the staates as it makes a good income for all. The saler and the mechanic who has to install it and later shoot out the trouble. Day will be to boring without "tuned" things.
