I just bought a 81 280zx N/a. I heard the one of the worst parts on this car is the EFI on it. I was wondering what the best way to upgrade it is?


Thanks alot !

 

Welcome to ZDriver!

Musta been someone who didn't understand cars. The 280z / 280zx efi is about as simple as it gets...

Best upgrade is to go MegaSquirt. The n/a efi isn't very tunable... there are a few tricks, but pretty limited. Not to sound like a total search ****, but do feel free to search. N/A upgrades have been covered in GREAT detail many times.

 

i do know of megasquirt and have heard awful things of them while i go to UNOH for automotive and high performance. Which one of the three would you recommended?

 

Hurm...

You'll be hard pressed to get anything to match Mega Squirt performance/price....

Whoever told you MS is awful I would stay away from them since they are likely completely incompetant...
