I am working on my friend's 2007 R56s which has a no start condition. while we're figuring the issue with his N14, I decided to drop my N18 in his car like what I've done on the clubman In this thread

Here is the car in preparation:

 

A little more work done last night.

 

That's looking pretty good. How do the electronics & wiring match up with the engine change? Does the car need to be told it's now running an N18? In addition to the dual vanos, what else has been redesigned/improved from the N14?

 

The engine harness and ECU are N18 specific. the only change will be in the body side of the ECU plug; last time I did it, it was 2 or 3 wires. I am still going to use the CAS and keyfob matched to the ECU until I figure a way to marry the donor ECU to the original CAS.

The PCV design is also improved. because of the dual vanos, the pistons and the head have a different design than the N14. it also has slightly more power and it is more quite than the N14.

 

All in...gotta do some rewiring to the body side ecu plug and do some coding.

 

I really wish I could do this to my 07. The N14 is a pain in the ***.

 

What's the issue with your N14?

I'm putting an N14 engine for my friend over the weekend. Never a dull moment lol

 

Cylinder walls are scratched. Trying to find a block now.

 

oh dang..I have three blocks like that
