911 oil tank in a 6 conversion?

[farleyd]

Hi, we had a post a month ago about fabricating our own oil tank for a 914/6 conversion. We are getting at it, slowly but surely.
Meanwhile, if i were to use a stock 911 oil tank, where would be the best location for it? Any options would be considered. As it would (may) be a temporary solution. The time we build our own.
Thanks to all.

Why would you ever want to do this? It's like making a 911 rear bumper fit on a 914. There's really no point, and you're certainly not going to save any money doing it...

Hi Wayne, well, a used oil tank is nowhere near available and new ones are 900US$ with fittings. Ive seen an OEM 914/6 oil tank going for 900US$ WITOUT the other stuff needed (filler neck, etc). This is going insane (prices i mean).

So using an early 911 oil tank is feasable to many. In fact, i am going to try it and see. If not, ill simply buy a 914/6 one. But dont you think that 900US$ is a lot of money for a mere oil tank??? And that will leave me with money to spend on other parts. Hello Pelican, here is my next order......

Oh, and if someone is willing to part with a used 914/6 oil tank at a reasonable price, i am buying.

BTW: my last order made it to Vermont in time. Thanks a bunch!

From what I know installing my tank, a 911 tank will not fit in a 914 without a lot of work. One of the main concerns is the oil suction line. Remember, the oil that goes from the tank to the engine is just gravity fed. Due to the $$ of a 911 motor, I would only use a time tested system. Wayne is impling is correct, the $$ spent on making this work is just not worth the time and money. My $0.03 worth.

Hi guys, that fact is new to me. You mean that a 911 tank installed in the front trunk wouldnt have enough to push oil to the engine by itself?

You probably understand my position, i still think that the price of the 914/6 oil tank, be it a Velios or a OEM one, is way too much. I am not trying to ruin my 911 engine, just not to ruin me... : -P

So, again, is there any other option besides the usual route - Velios and the likes? There must be someone who tried the same thing as i am doing?

As you said Wayne, there is only 2-3% of people who goes from talking to DOING a conversion. I am one of those 2-3%. I have already plunged a lot of money of parts, and still have to see the day i see the tach spinning - poetic.

Wayne, contact me privatly to give me the price of the whole 914/6 oil tank package: tank, filler, lines, etc. and ill see. Best thanks to all.

When I was going to do a /6 conversion I had planned on using a 911 tank and install the tank in the rear trunk area. From what I was told by a few respectible PCA'ers, this has been done successfully more than once.

Uhh, you must be shopping at my competitors. The aftermarket tank is $500, and the original new tank is $645. $595 if you catch me on a good day...

Definitely worth it, unless you make $6/hr, and you can afford the 100 hrs it would take to make your own tank. Plus, don't forget that 911 tanks are not exactly cheap either...

Wayne, if that line was for me, dont worry, i am loyal to Pelican. You deserve it. And you (we all) know what i think of AA! They banned me from their Ebay aunctions, i criticized once. The good Dr. didnt appreciate, i guess.

As for the 911 set-up, id like to give it a try. Ill see afterward. The aftermarket tank is tempting at the price you offered, but add to this the multiple others items - filler neck, etc, its still a bunch of $ for an oil tank.

Question:

What parts are involved with a aftermarket 914-6 or 911 type oil tank?

You will need an oil filter console and filler neck regardless of which tank you go with.

If you want to use another tank - don't go with the 911 tank - it's not designed for that, and will not easily fit anywhere. There are other dry-sump racing tanks that will fit. I know someone who fit a helicopter oil tank in the left side of their 914 fender. Good job too. He got the tank for $15.

The 911 tank is not a good bet - the oil filter console will be hard to fit anywhere. Use a different tank...

Hello

Had made a setup with a selfmade tank siting beside the starter. Was filled in the trunk. trunkfloor cutet and a cover door made to keep the trunk usable used a modified early oiline runing into an tube style oilcooler where the factory had the oiltank. Then back inside to a standard 2,4 oilfilter base and back into the tank.

The feed line was just a rubberhose on a 911 cooler witch had a cut back tube.

Run in many problems and learned a lot.

One was to store the oil in the oilcooler as the tank was to high level flooding the engine.

The system was inventet and used on a drysump type 4 and startet with a beetle sportomatic oil bowl tank on the passenger side of the trany.

IAs Wayne said you can´t use any 911 tank even on the 911 the tank can starve oilsuppley under hard cornering and when you use it reversed.

Also there isn´t enough room so you well trash up everything.

Maybe a superslim tank will fit in the forward left corner but you have the heat inside the engine bay.

Avoid to lay the tank flat or in higher position. Keep in mind that the oiltank must have enough capacity at the base engine oillevel.
IF you go may way you need a checker valve, cost flow and have risks.

Try to find a rustet 911 tank for cheap money and cut it open. You can reuse the oilfilterportion and see how the mesh works. Also the oilevelgauge cut out and the fitings are very usefull.

A friend of mine bought a "complete, but Not Right" 914-6 conversion a couple of years back. The car had fiberglass fender flares installed, and a 911 oil tank was mounted in (more or less) the stock 914-6 tank location.

Well, rather less than more. There were about six extra holes cut, plus the tank didn't sit very securely, plus the fittings were being bent because they came out in the wrong places, plus it leaked from everywhere, plus....

So it can be made to work under GT flares, but the most likely outcome is that you'll wind up with a real hack-job. [I've started shying away from "You Can't Do That", or "It Is Always A Hack Job"--Sammy G's and Ed V's 914 turbos have proven me wrong on those statements in the past.] The 911 tank will not even fit (from what I can see) under the stock fender.

Is there any tech articles or any info on installing a 914-6 oiltank?

I am panning to eventually install a front mounted 914-6 GT type oil cooler and oil tank and am interested in any and all info available.

Thanks,

Personally, I wouldn't screw around with trying to fabricate an oil tank or tweak a used 911 tank to try to cram it in the 914. If you end up with a leaky tank or one that has flow/plumbing problems, the few bucks you "saved" will be down the tubes because you'll have to redo the whole thing -- assuming you don't run the engine dry and blow it up in the meantime.

Not to mention if you ever try to sell the car and the prospective buyer sees a "mickey mouse" oiling setup. I would run away, myself, if I saw a homebrew oil tank that did not look 100% "right".

I have seen "good" used /6 tanks advertised on the net in the $400-500 range, and there's always the option of a custom alloy race-style tank like this:

Hello

Thats engine killing.

Under hard accelerating the the oil will rush backwards away from the the outlet in the tank and also from the pickup in the engine.

Invitation to Murphy.

Yeah i know people who spend 10000 $ parts in upfixing a 911 engine and had no money for a new oiltank. After several months the engine died screaming blue as no oil was on the bearings. They where claiming waranty as my employer made the long block then. This guy brought it to the next local Porsche dealer. The dealer rebuilded the engine and sended the bill ( Well no expense spared all new ) to us. They didn´t know what happend the passages had been blocked partially, but it must have been our fault. After two weeks the new parts had been blue again and I sent a staate approved engenieer to have a look at the car.

When he came the engine was dissasembled and he asked the right questiions and looked what the Porsche dealer made. The new crank had blocked oil passages. They then opend the oilfilter and had found some rust in it.

The end was the oil tank was restoratet. The unit had some rust holes on top and some thin areas abouve oil level. Someone reskined the inner side complet and to save time he left out the mesh and also nearly all from the old rustet sheetmetall inside. like I said reskinned had a very good finish outside. The chopper inside was burned away due welding and after a while the rust flaked away faling down and suked into the oilpump tehn send to the oilcooler wher it got depositet for several days. Untill the owner hit the throtle and the oilpressure flushed the oilcooler in one fast rush pressing the rust into the main gallerys blocking off the oil sprayer, the bearings and the oiltubes from the camshaft.

And the best was the owner had paid the guy to fix his tank. Wasn´t a high bill for the tank repair. I think something around a new Porsche then.

Just avoid follow ups on those thrills.

OK, then you had me (almost).

Who has a spare 914/6 oil tank!!!!!!!
