Need new engine: 370z or lower kms Skyline?
 

Hey guys

I have a 2009 370z. I think it's overheated and developed a cracked head or gasket as it's putting out smoke when first starting and getting oil into the spark plugs, so looks like I'll need to replace the engine.

I have the option of:

1. 63,000km engine out of a 2010 Nissan Skyline Cross Over 370 GT. VQ37-100936. Hasn't been run in 5 years though after being written off.

2. 74,000km engine out of a 2009 370z, written off last year but appears to have done 17,000kms in the 6 months before being written off, so probably driven hard (probably why they crashed it).

Both are same price ($3500). Anyone have experience getting a VQ37 engine out of something else (Skyline) to go in the Z? Or would I be safer just getting the slightly higher kms model?
