I want to build a z and I want to plan it right. I just finished a corvette that was a nightmare because it was one thing after another. So this time around I want to get a motor and familiarize myself with it by tearing down and rebuilding. Are there any specific years that are better? And what are the best carbs as well as what gets the most performance while not being over the top? Any suggestions and common problems to be aware of would be helpful.

Get a 280zx 2.8litre motor with P90 head (not P90a)

For carbs get triples (SK Racing. Weber, or Mikuni)

Thanks.and is there a specific year for the 280 z motor?

Just look for F54 block, it has flat top pistons.

Thanks for the links. Very helpful

How fun is the driving with the f54? Im looking and see so many swaps being doin primarily with skyline engines. Obviously its more cost effective going true to the era. And I think it has more character if the car has a rebuilt, nice and fine tuned engine. But for how drivable it is and responsive....what are your and anyone elses feelings on the original engine.
