Can some one explain, that I find most books, show 901/36 as the enging ID, how ever others say 901/38 is possible. But most all list the rare 2.7 engine as 901/38.
Question is 901/38 2.0 & 2.7? Or is 901/38 exclusively the 2.7?

I need to know!

I meant ID 6, confusion, not 3 obviously

Here is the explanation.....
I'm quoting this from pg. 60 of Bruce Anderson's Porsche 911 performance handbook:

"The 914/6 engine was the 901/36 for the European standard transmission, and type 901/37 for Sportomatic. The U.S. 914/6 engine was type 901/38, or type 901/39 for the Sportomatic."

Here is something I found interesting at the bottom of the same paragraph:
"A 2.4 liter version of the 911T engine (Type 911/58) was developed for use in the 914/6, but was never used in production."

I've never seen a 2,7 called a 901/anything and I'd love to see a reference that does.

Porsche changed engine type numbers from '901' to '911' in 1970 with the 2,2.
(These are 911 engine type numbers - 2-liter 914.6 engines retained the '901' series numbering.)

One learns to 'never say never' with Porsche, but "almost invariably" if it's bigger than 2,0 it didn't leave the factory with a '901' type code.
