1970 240z

Will, I have a 77 280z with RB25DET Neo and I am running ac. I had no clearence issues with the RB AC compressor (looks to be the same as a 2000 sentra other than sentra has larger pulley). I did have a failure with my RB compressor so I switched to the 2000 Altima comprssor as it is more durable, I had to change the fittings on my lines at the compressor as the ports were located differently. The Altima is also physically larger. It still fit but was a tighter fit than the RB/Sentra compressor.
