Need more power for 1986 Nissan sunny

[Jamesgaynorjaff]

Hi all, might sound like a mid life crisis but I brought a 1986 Nissan sunny 1.3 petrol, I love it and I would like just a bit more power.

its only done 42k the engine sound very healthy and I’d like to add an exhaust and intake filter.

i would also like to know if there is anything else I can do eg change or tune the carb?

I have a set of lowering springs in the post (35mm) and I will be getting some nice wheels also very soon.

so it will handle slightly less boat like and sound fruity.

im struggling to find information on what can be done to my sunny but then it is nearly 40 yr old lol so any help would be great or links to parts I can buy 

many thanks
