That 3.0 sucks monkey balls.total waste of time. They could have at the very least cleaned the engine when it was out. If I had a 510 I would have to put a RB26 in it however since pigs don't fly I'd stick with the next best thing. a GNX510
350Z isnt the best nissan ever. I'd give up my 350Z for a mint 240Z with warrenty.
One day If theres any left I'd love to find a 240Z and drop a L28T motor in it.
Notice how I DIDNT say to put a 3.5 in it? 350Z is a great all around car but it shouldnt have anything to do with the 510. the GNX motor would be a much better choice.
once again the GNX has nothing to do with the 350. I'd even put the L28T in the 510 before the 3.5 from the 350.
