So I have a Nissan Micra K11 sport, I'm looking to improve the speed of it as it does not have much go at all, it seems very sluggish and I need some help on ways I can improve it.
But your first port of call for performance would be exhaust system ( frankspeed manifold is decent if you can sweet talk frank) or a janspeed 4-2-1 ( pricey but worth it) and a GA16 airbox ( larger micra box off an almera)
