The engine number on my sweet '76 914 2.0, made in 10/75, with only 61k miles on it, is GC005071. VIN is 4762902176

Pelican says this in an old posting: "The 2.0L engine cases always started with the letters GA or GB."

They also say, "VW Bus Engines in 914s - This one occurs much more than you would think. When the engine inside the car doesn't match any of the 914 serial numbers, chances are that is an engine from a VW bus. Most of the time, these engines will be carbureted"

Well, mine wasn't carbureted in 2005 when our local Porsche dealer removed the D-jet system and installed the carbs - I have the service records. They had a bad ECU and could not find a replacement. I have it in writing.

So can anyone assure me that my "GC" engine is indeed a 914 engine - and thus Pelican is incorrect in their statement about 2.0 engines being only GA or GB?

TIA,

GN

You're good, Gatornapper...
GC was the code in '75/'76 for the 914 2.0L

Thanks guys! I thought it was probably good but needed to verify. Surprised Pelican has the error.

All numbers and codes on car look good.....another member with a really nice 914 drove it Friday and was amazed at how tight the suspension is and how well it shifted - markedly better than his restored '72 with a new 2.0 engine........the doors sound & feel like a new car when closed from 6" like they should be....the car is an amazing barn find....abandoned 14 years ago in a friends new (in '05) barn.

As I've been digging into the car now for 2 years, everything I discover is only good news - an LA area car in amazing condition - soon to get a set of Mahle's on it....

Oh, D-jet going back on engine once all the engine's internals are proven good and I get it running super-well on the Weber's......probably spring.....compression is 118, 118, 115, 120.......

Sorry, can't figure out how to delete this. Correct one below

This is from a 914 book by Dr. B. Johnson (1999). Looks like your VIN and engine numbers match the GC sequence from 1975 to 1976 2.0s..

Wow - cool! Thank you so much! Looks like mine one of the last 2000 made.....

Never cease to be amazed at the depth and breadth of knowledge on this forum.....
