Looking for the 914-6 engine serial number 6400875.
A European 901/36 version, apparently removed while in the Netherlands during 1985-1999.

Full Version: 914/6 engine serial numbers
looking for 6405179
For those selling 914-6 engine cases and those thinking about acquiring the original engine case for their car. Here is my opinion on values:
I've been tracking 914-6 sale prices for the last 10 years. During the big bump over the last 2 years, the average sale (actual sales not just asking) price of a numbers matching car vs a non-numbers matching car is a $20k difference. However, it is not just the engine that makes this price gap. Most of the cars with a numbers matching engine are also more original, better cared for examples.
I have run across a few 914-6 engines that are being offered for 5 figure prices. Others have been purchased and then immediately offered for 2 or 3x the price, even as a bare case. Some have been sitting in the back of a shop for 30 years, in "as removed" condition.
A complete engine that was removed in the 80s for an upgrade and has just been sitting indoors may have an engine case in better condition than one that has been apart or stored in a less weatherproof environment, but if it is not currently running with compression and leakdown numbers, it's just as much of a mystery internally. It's highly likely that the car had 100k miles on it in during it's first 10 years on the road, and most if not all of the parts in that engine are worn out, which is why the swap was done in the first place instead of a rebuild.
As an example of what it will take to get the case back to operational condition, I sent my own numbers matching 914-6 engine to Ollie's last month. The engine case looked in fine condition with no visible damage or modifications. I didn't order any extra special racing mods, just the standard upgrades that any engine rebuild should consider like oil bypass mod, piston squirters and stud inserts. But because most if not all magnesium cases warp with heat and age, Ollie's says almost all mag cases and even most Aluminum cases they get these days require align boring.
So the complete list was:
Inspect
Align bore
Spot face through bolt holes
Head stud inserts
Weld at #3
Media Tumble
R&R oil plugs
Hot Tank
Oil Bypass Mod
Install Piston oil squirters
The total was $2462, just to prep the case.
The rest of the rebuild costs will depend on what your tastes and goals are, but the minimum is $10k if you don't want to do it again.
So, no your old dirty rusty corroding pile of 69 911T parts is not worth $10k. I sold a case to a user here to re-unite with it's chassis for $1500. The rest of the original parts are effectively worthless. T cranks are $300 even if they are std/std. 69T heads, no one wants them. 2.0 rods are $100 a set. T cams worthless. Cam housings and chain boxes also valueless, I have 5 extra sets and so does everyone else. Early 11 blade fans are worth $300, if they aren't chipped with rusty pulleys. Worn out Zeniths are $500. So maybe that old pile of parts you have there is worth $2500.
So what is a numbers matching engine worth? If it's a running driving engine in the car with induction, it has an ~$10-15k bump to the value of the car. Which makes it worth buying a $1500-2500 engine case and spending the $15k to rebuild it and get it in the car. But I would not recommend that anyone spend $10k+ for a core engine or just an engine case in unknown condition.
Remember when negotiating, as the person with the matching chassis you are the ONLY person in the world that values that engine case. No one else can do anything with it that makes sense. And as the person with the engine case, remember that the 914-6 owner has to do a lot of expensive work to do to even make it usable. So quit trying to cash in on the $10k price differential when you got that old dirty thing in your shed for a few hundred bucks at a swap meet way back when.

Sorry, But I'd think
If you can actually find your matching number case,...... BUY IT.. It will never be worth less to the owner of the car...
Not to say you don't negotiate the price if you can...
Seriously... What it adds to the value today may be one thing, but in the future can't be determined. Who ever thought these cars would be worth what they are in today's market ??
My original engine is sitting on a shelf in my garage..36,000 miles and never been apart.. What does that add to the value of my car ????
It will never go back into the car in my lifetime... Not worth the risk of damaging it..
just saying...

If my original engine/case ever popped up, 6414135, I would try to buy it. 
6414044 case is on los Angeles Craigslist. It looked pretty bad and needs some weld repair. Its listed in an ad with other 911 cases.
6414044 is new on the list. Asking price in the CL ad is $1800 each or "buy all three" meaning in a pkg with the other 911 cases. I noted the phone number in case someone needs it.

Just saw someone post in the garage that they have a 6 with it's matching # engine.
I have engine 6405500 and would like to find the car it belongs to..
Without giving someone else's info, lets just say if they run reasonably close, 5500 should belong to a car in the early 32300 range..
If that is you... let me know...

Can someone give me relatively educated information on value of non-numbered case engine ( I know condition matters) but I want it as it relates to value of a restored car.
That is, if the price of a nicely restored six = 10 on a scale of 1 to 10, what is the price of a non numbers matching and then a non numbered case.
Thanks in advance for feedback.

I have tried to quantify this but I see non-numbers matching cars fetching as much as numbers matching cars. Just to throw a number out there I would say $5k-$10k more with matching engine and trans that is why people charge $1500+ for otherwise useless 914/6 cases. I say useless because it cost as much to rebuild a 2.7L as it does a 2.0L and who would opt for less power.

Hi all,
I'm looking for engine 6404756 or at least the case. Been able to determine that it was replaced with a 2.4 T motor in Canada, probably Calgary and most likely before 2008. Any info regarding this engine would be greatly appreciated.

FYI, I have 6404270 which has just completed a complete rebuild. I had thought for a very long time that this engine was original to my 9140430893, but PCNA tells me that it is not. Of course, they no longer tell you which is the right engine, just that this came out of some other car.

I just saw this on Facebook in the Porsche 914 Owner's Club (no affiliation):
I just purchased a collection of cars here in California. One item the collection included was what I thought was a 911 engine. After some research I discovered it is a 914/6 motor. It is a 908/38 case with the number 6404542. It looks like it was rebuilt as a 2.7L (1976 heads) and then put in storage.
I'd love to reconnect it with its original car.

Hello.
I'm looking for 6410148 last heard of at Sonauto(Paris) when they fitted it into another car.
I've currently got 6400453 taken from a French car by Sonauto.
I could also do with finding my transmission 510169 removed in France and I now think its in the USA.

Because the engine numbers are split between US and RoW, the chassis and engine diverged very quickly. 6400453 would be in VIN #1000ish.

It is an incomplete engine... Case, crank pistons and rods..

Anyone have any info on recent sale/purchase of one of the 901/38 engines, with prices, not asking, but actual price paid. Not for the correct car/engine match scenario, just an engine without a home. I ALWAYS hear how worthless these engines are, without the correct chassis number buyer, but I think someone forgot to tell the folks selling them...reason is I have a mostly complete 1971 901/38 I am considering selling to get my "now found" engine, which I assure you the guy wants me to PAY!
My engine is very complete, never been apart since assembly, and I am VERY sure the car has long ago been returned to Mother Earth supposedly in Alaska at one point. The Engine S/N is on the 1971 year model list in the first post.
Actual engine for my car is now only case, crank, pistons and cylinders. Rest removed and used as required somewhere else...

Hi Guy, I searched my database and found cars with engine numbers on either side of yours. 6405500 and 6405502. No luck on your engine number.
