Injectors
 

Does anybody know what size/colour injectors are available for my classic MY99/00, and are they diy job?? car has standard at this time.. ie..
YELLOW.....440cc.
What would be the gain of fitting a larger capacity.

Blue are 550's
Red are 740's

Both are compatible with Phase 2 (99/00) fuel rails, but if you use the 740's you will either need to modify the injector or connector, or buy the correct connectors ( They are Nissan fitment )

You only need to consider upgrading if you are hitting 90/100% duty cycle on your existing 440's, and you're needing some extra headroom so that you can push your tune a bit further.

Unless you are getting close to their limits, it's pointless changing them IMO :)
