The original 1976 MAG cast block was cracked so, Stephen Kaspar (Kansas City) sourced this 67 block and machined the 2.0L The spigots and some other few changes made to accept the 2.7 JE pistons and cylinders as well as the crank, oil fed chain tensioners, oil pump and new bearings. The intermediate shaft was also modified and an updated intermediate shaft gear cut, new rockers arms, elephant teeth, etc . .
Updated SC cams were used as well as a 1967 distributor was also used to keep the "old school" look. The entire fuel system was replaced as well. The exhaust consist of headers to SSI stainless pipes. It sounds fantastic and pulls all the way to 7,000rpm. The motor costs as much as the car did, but I am completely thrilled with the outcome. It dyno'd at 225 hp and 212lbs torque.

On an interesting note, Stephen also custom built a four wheel Bilsten coil overs set up for this car and lowered to euro ride height. It drives smoother than my 1988 Turbo. It has been a dream to drive these past few years.
I added the Carrera script, the duck and chin spoiler to make the car look like it sounds. I have the original Mag block and trunk lid.

Sweet set up! Seriously, I bet that's one sweet ride :eek::eek:

1976 2.7 I think
 
Can someone help me decode this number. It currently sits in a 1970 914-6 that I am about to restore. I believe it is a 1976 2.7 liter from a 911S.

engine number *64O5325*

Grady Clay 09-06-2011 05:41 PM

airtightonline,
First, Welcome to Pelican SmileWavy
You will find a lot of help here.


*6405325*
That is an original 914-6 engine, Type 901/38, USA spec.
The engine number range for the 901/38 is 6404001 to 640xxx.
There is not good documentation as to the last number but the 901/38 is the USA emissions version for a manual transmission.
Yours is the 1325th of that series (very late I think).
There are some number of the RoW, manual transmission Type 901/36 (6400001->)built.
I have never seen a 901/37 (6403001->) or 901/39 (6407001->) configured for the Sportomatic.

What is your VIN? (914043xxxx)

Best,
Grady
Own two 1970 914-6s, one since ’71. :cool:

Thanks for the fast reply.

My 914 VIN # is 9140431904

I took the engine code from a stamp i found near the oil inlet. The engine is still in the car. The fan shroud says 1976 911S. The car is a 1970 914-6. I appreciate all the help. thanks.

Grady Clay 09-07-2011 10:18 AM

airtightonline,

So, you have the 1904th (sorta) chassis with the 1325th (sorta) 901/38 engine.
The difference probably are the chassis with the RoW 901/36 engines.
Porsche didn’t distinguish RoW from USA in the VIN.
The “sorta” covers the first few prototypes/development/test chassis.

You have *6405325* and 901/38 stamped in the top of the case.
There probably is another (3rd) number stamped near the breather: a ‘build number’.
If there, what is that number?

We need pictures.
What are your plans?

Best,
Grady

914-6 restoration
 
Grady,

It is getting the motor removed and rebuilt as we speak. I am planning a total restoration back to the way it was when I first drove in it (1978 I was 6). My uncle made fiberglass parts for Porsches in the 70's and early eighties in Los Angeles,CA. He had this 914-6 as a show piece. It ended up in a barn for 20 years. In 1998 he gave it to me. I finally am in the position to start the restoration.http://forums.pelicanparts.com/uploa...1315424263.jpg

Interesting project!

The copper brown color with the orange and yellow striping would certainly be of '70s vintage! I dig!

Grady Clay 09-08-2011 10:50 AM

airtightonline,

Why don’t you start a thread on the 914-6 Forum and post a link here.
Many would be interested in the history and plans.

BTW – is there the 3rd number on the case next to the engine number and type number?
What are your transmission numbers?

Best,
Grady

I thought I knew how to read these eng Nrs, but one motor here hanging in my 71 T has me confused.

It has # 6531656. (edit- There are no Stars before & after the number either)

If this is a 73 motor, what does the "5" designate?

Its too dark to read the eng type but I will do this in the AM.

Len

BoxsterGT 09-17-2011 06:57 AM

:)

I see that a 73 RS motor has 663.......as the first three digits.
What the heck is 653....?
My engine type code is 911/57.

Len

:)

Grady Clay 09-17-2011 07:06 AM

6531656 decodes as:
6 = Engine designation, 6-cylinder unit.
5 = Engine type TV-E, 911/57 (911/67 w/Sportomatic).
3 = Model year 1973.
1656 = Sequential number.

The 911TV is the RoW 911T with Zenith carburators.

Best,
Grady

Thank you Grady.

Another newb here with engine numbers. I recently was given a pickup full of parts from a recently widowed friend. The car was sold but her husband saved everything he took off the car when he replaced them with new parts but the buyer didn't want them. Some parts are new too. The case number is 6450062 and the type is 911/43. Not sure what to do with the parts. I've always liked 911's since I spent some time in Germany in 71-73. Anyways, based on some of the pics I've seen and the body parts I have, they are off of a 76? I also have a set of heads, casting # 911 104 342 2R. Another # on the intake side of the head is K18119s. There's also a 5-74 before the K# Any help would be appreciated. I'm an old gear head and wouldn't mind getting into a 911 and this could be my start.....if the boss gives me the green light lol. She did have a 914 once but we won't go into that :D

Welcome to Pelican Cranky1 SmileWavy
You'll find a lot of help here

Here is the info on your engine#6450062 (62nd in the sequential build for that year)

Engine Type: 911/43
Year Manufactured: 1975
Model: 911S USA engine
2.7 liter, 2687cc, 165hp@5800 rpm, 226tq@4000 rpm, Bore/Stroke 90/70.4, 8.5:1 cr, Valves Int/Ex 46/40, Ports Int/Ex 35/35, CIS fuel Injection


These engines & 911s can be a ton of fun (rebuild to 2.7 Carrera RS spec), but these mid-year 911s (1974-77) need prompt attention to several well known weakness.

If not remedied these weakness could cut short the life of the engine making it a very expensive process to recover from. (some owners replace the 2.7 with a 78-83 3.0 CIS motor and sell the 2.7 for parts)

Check those head studs, remove the thermal reactors on exhaust system replace with SSI type exhaust, Fan blades should be updated to 11 blade from 5 blade, chain tensioners should be replaced with Carrera or 930 type... Lots of other upgrades for these engines that should be attended to... Tons of threads on these here as well....

With the proper attention these 2.7 engines are a lot of fun and reliable too

Good Luck Cranky1

Cheers!

Cranky1 09-22-2011 04:36 AM

Thanks for the info!! Apparently, those are the mods the previous owner did because I have most of the old parts that he took off the engine including the 5 blade fan. I was wondering why there was a fan in the box and now I know. Again, thank you for the info and the welcome!

3.6 Engines: According to Bruce Anderson's book the engines produced for the 964 and 965 cars from 1989-1994 had only world wide specifications. There were 4 versions; one for the tiptronic, one for manual, one for the 3.3 turbo and one for the 3.6 turbo. So if you import a 3.6 for those years you are importing an engine that is the same as the one sold in the US market. Hope I am correct.

Freak,
I just put this 911 S up for sale. I need to buy a new car for work and for my 16 year old son. This seems like a good way to raise money. Any takers on a good car or SUV ? ? ? Sounds horrible, but reality calls.

John1180 10-04-2011 02:40 PM

Hi I'm looking for year and spec info on my 3.0 liter engine number is 6671145
Thanks, John

Welcome John!

What you have there is a very special 3.0l from a 1977 Carrera 3.0
The engine type # would be good info. Plenty of info about location on this thread, take a look and post what you find. Probably 930/02

Back to your 3.ol #667 1145 (1145 is the sequential build #)

1977 Carrera 3.ol, engine# 667 1145, Type 930/02, 200hp@6000rpm, 255tq@4200rpm, bore/stroke 95/70.4, 8.5:1 cr, Valves Int/Ex 49/41.5, Ports Int/Ex 39/35, CIS Fuel injection

Do you have the matching number chassis and 915 transmission? Option codes?
Pictures?

Cheers
Jason
