Im in the market for a 2005 G35. I have one that I'm looking at and plan on buying. The only issue is that it's got a blown motor. The seller has a motor already from a 2008 350z. I dont know the trim level of the z he just mentioned it came out of a 2008 350z and only has 18,000 miles. My question is will this bolt right up to the existing transmission and harness or will their need to be modifications to get it running. This needs to be plug and play. I've done motor swaps before so it wouldn't be my first however I'm new to Nissan's and Infinitis and trying to get some background information before I buy this car. Thanks for the help and I much appreciate it.
