Hi group, a friend has a 2014 model r8, it had a catastrophic engine failure at 40,000klm. He has found a low klm good engine from a 2007 model. 2014 is CNDA and 2007 is BHY. Can anyone point us in the right direction to see if this engine might fit to get his dream back in the road.

They are different engine architectures. The CNDA engine is the 5.2L with 2 cylinders lopped off... the BYH is the same engine as the RS4. I hope that helps.

As forum members know, I am the original owner of a gated 2015 R8 V8. I had no idea that the facelift V8 engine is different from the earlier cars.

Is there a compression difference between the CND & BYH ?
I’m about to replace my CND with a BYH due melting a piston on the CND
