Micra K11 1.0L Engine Mods

[GRANPOPS]

I have a K11 1.0L Micra and have already fitted a cold air induction kit and performance exhaust back box.
I intend fitting 1.3 camshafts and 4-2-1 exhaust manifold.
Anybody know if 1.3 injectors make any improvement?

Injectors are exactly the same and unless you plan on mapping dumping more fuel into the engine isn't going to be of any help

With such a small engine all the basics will make a significant difference. Mine feels so much pokier after a really good service; engine flush, all new fluids, new plugs and a new filter. The lighter wheels have made a big difference too!

I'm a big fan of making the most of what you have, keeping everything clean and in good condition will reduce the mechanical drag, resulting in more power at the wheels. Plus, new oem parts are cheaper than fancy aftermarket bits!

The next job for me is to work through all the electrical connections, clean them out and replace any that are in bad condition. Checking the earths in particular are all clean and corrosion free is very worthwhile.
