03 vs 04 busa

[whzyrd]

is there any other differences between the 2 years besides the passing switch.
thank you Rich
reason im asking is there are no more o4 in az but a dealer up north has an 03

 

[sageronin]

Passing lights switch and hazzard lights switch .. . I think that is all.

What sageronin said. Those are the only visible things I know about. I haven't heard/read anything about the internals that's different.

 

[dezzy7]

I've been checking of late and those two are the only differences.

 

[banditoo]

the '04 has a "better" fuel management system for smoother running ... that's what was posted on the Zuk website awhile ago for the new model.

I think your right Bandit.  The 04 has a 32 bit ecu where previous busa's have a 16 bit ecu ?? I could be wrong though.

As far as I know it's the Passing switch, the Hazards and the new upgrade ECU. (from 16 bit to a 32 bit)
