Undeleting heat-delete...What am I in for?

[Tremelune]

I'm looking at a car with no heat, and I need heat. The chassis is an '80 Euro SC and the motor is an '84 Euro 3.3L turbo. It has SC cams, an Andial intercooler, K-27 11/11, Ruf R4 muffler, and a factory RoW oil cooler...

The interior controls were removed, as well as anything in the engine bay (presumably). I fear the cost of a new OEM system. Someone told me about an aftermarket solution that would wrap around the existing headers...I'm new to 930 modification and plumbing and I'm in over my head. I would almost surely need a shop to get the parts in for me. Because the motor is heavily modified, it's difficult for me to know how the parts interact with one another.

Here's a shot of the headers:



It looks like I could go with stainless SSI headers for $2k or try and get a modern gas heater installed in the frunk and not mess with the motor at all...I'm trying to get a handle on all the variables in play. Any insight would be appreciated.

If all the controls are removed, this will obviously require some work.

On the headers, some of the options could be:

1. SSIs ( as you mention) this, I believe, will require a socalled Y-pipe to be able to mount the turbo to the headers. RarlyL8 sells this. Also, I think it requires different cross-over oil lines to be able to use SSIs.
I believe the SSIs are at their limit size wise when mounted to a modded 3.3 turbo, but others can chime in on that.

2. Buy a set of rarlyL8 headers assuming you can get them with heat.

3. Buy a set of B&B or equivalent. I think TurboKraft sells those.

It is not terrible difficult to put the heater controls back in. Especially if we are only talking about the manual part. I have just done that, on my Carrera 3.0

If this is a cheap car, and that is what attracts you, but it does require some work. I would skip it and buy what you really want.
It is always gonna cost you A LOT more than you expect.

Good luck

I bet most of the mechanicals are still there, really difficult to completely remove.
Get a set of headers w heat, the cabin controls should be easy and cheap.
In the other hand, there are so many good card put there, unmolested, why not keep looking.

[Tremelune]

This is all good info.

The car is/seems sorted, and needs no work...except heat. I believe it's only missing the exchangers, blowers, flapper boxes...The rest is either still installed or in a box. Everything is more modified than I like, but in a seemingly well thought-out way. As I intend to modify whatever I buy in other ways, I can't bring myself to monkey with a rare, original example while the paint deteriorates outside.

I'm not specifically in the market for a 930, just a wide body. This car just happens to also come with a Turbo motor and serious brakes. I wouldn't mind almost twice the power of an SC...$2k I can swallow for everything else, but more than that and I'm in not-the-one-for-me territory. If I were more familiar with 911 heating systems and the 3.3L motor, I wouldn't be quite so intimidated...or maybe I'd be smart enough to walk away.

So...I research.

Hey there,

What do you mean by serious brakes? Does the car have the 930 4 spd. tranny or is the turbo engine mated to an SC 915 5 spd. trans?

Real 930's have real serious brakes, better rear trailing arms (double bearings), strong 4 spd. trans, blah, blah, blah...they are quite a bit different than a SC. If that does not matter for you, then maybe the car could work for you.

As far as heat goes, swapping out to an earlier manual heat lever system in the cab is a common cure for the troublesome "auto heat", and is easy to install. The 2 foot well blowers up front aren't that effective, so you can do with out these, simply for heat. The engine fan is sufficient for cabin heat/defrost, so buy the rear flapper boxes, manual heat lever/parking brake assembly, the associated hoses and your good to go as far as the cabin is concerned.

Your on your own for your choice of headers with heat, since there are multiple selections out there.

Beefed-up 915, big reds up front, 951 front brakes on the rear. Suspension is fairly stock SC.

It sounds like there are number of options to get heat into this thing, and that I could get out under the $2k mark if desired.

Does anyone have any experience with the Rarely8 boxes that wrap around the headers? Must they be mated to the headers they sell?

I think you're gonna be way over 2k, maybe 4-5k. A 915 tranny is not up to the task w a turbo imo....

[Tremelune]

Well, it looks like I can get used OEM headers for ~$350, or source a modern gas heater for $650, or buy some wrap-around exchangers for $300...Throw in $1000 for flappers, levers, tubes, bits, labor, and (possibly) light fab work, and I think it's doable.

[9dreizig]

Sounds like quite the Frankenstein930 good luck!!!

this is the car been for sale for a while

1980 911 turbo

Our heat exchangers will only fit our equal length headers.
If I were in your shoes I would either have a fab shop weld up a pair of heater boxes or sell the headers you have and buy a set with heat. If the controls are missing I would walk away from the car. Been there done that won't do it again.
A built 915 is a ton of fun in front of a 930 engine as long as you respect the weak points. No drag starts just let the turbo do the work.
Nice car for the money, unfortunate it was stripped of the HVAC system.

[Tt surgeon]

Agree, I'd prolly buy a set w heat, 2500$, that's just the start....

[M5guy]

Gebrings sells awesome heated jackets, seat cushions, and gloves, and I swear the heat goes all the way to 11, like a custom built Spinal Tap guitar amp. It's what has kept me warm on motorcycles on long rides in 40 degree rain. Just plug them into your 12v socket.

Btw I had one of those single spark plug German gasoline auxiliary heaters in a VW van a few decades ago. Interior temp would go from 20 to 90 degrees in about 10 minutes. Noisy, smelly, semi-dangerous, but plenty of heat. The Ebersbacher B2 heaters were seen on early 60s 356s, Beetles, and vans.

Converting the front seats to heated is pretty straight forward and not costly, I oem heated seats in my daily driver and I never use the heater, the heated seat is much nicer than dry heat blowing around you I think. I really miss my heater though, the 911 heater went from zero to windows down in about a minute!

Here are some headers for sale FS PowerHaus 930 headers with heat
I would pass on this car though, my .02 cents

You could also follow Roland's lead:
Gas heater installation

I'm actually giving that serious consideration. I'm left wondering if there is a Porsche shop that could install that for me. It would be tricky to do myself outside in the cold.

Do you say that because the car/motor is heavily modified, or because the parts/modifications are of a poor quality?
