2005 Nissan Sentra Modding help!

[WRX_FJZ]

My Girlfriend has a 2005 Nissan Sentra special S 1.8L.

So I was looking for someone/someones who might be able to give me a list of parts and what not, to help give her car that extra pep it really needs. increased horse power? newer suspension for a smoother ride? maybe dropping it?
Air intake system?
Exhaust?
Some type of chipping system?

Its an old girl with 77K miles so I want to help that old girl.

Iv been looking around on my own to try and figure stuff out, yet I'm failing. so hopefully someone around here can help clear stuff up and give me some kinda list of stuff i can do.

Thanks for yall time!

the 1.8 isnt a very popular engine for tuning, from what i can tell (some people may say otherwise). you could probably find some under driven pullies, cold or warm air intake, exhaust sytems, and some other basic bolt-on stuff, but short of tearing it down and building internally, i wouldnt expect much out of it all.

if your wanting any real power from the sentra, you need boost (if this engine is even good for it... idk), or one of the larger engine options, like the very popular 2.0l SR20DE, or the newer 2.5l engine that comes in the Sentra SE-R and Altima 2.5s'.

as for suspension, pretty much anything made for the SE-R should bolt up. its all the same body. same goes for body kits, wings, wheels, etc.

I have an 05 SER spec-V and i wanted to do a header and catbak, but wont we all need a tuner to correct A/F on the dyno? Im new to the "tuner" side of the house.....this there even a handheld programmer for the sentra?

No need to get a tune after header and catback.
