Hello,
I wanted to know what should I tune on my Sentra.
It's a 2004 and has 120000km. I don't wanna spend HUGE money on it, just some little things that can make it a bit faster and funnier to drive.

Also what to NOT do/add on my car.

Thank you!

The best mods for a car engine are as follows.

Internal work yields the biggest gains, head work like porting polishing and 3 angle valve jobs will maximise the airflow and raise the power.

If you want to go to the max then cryo treat the block, get it rebored and look into blueprinting and balancing as well.

Bigger valves are an obvious addon but not all engines are suitable as it depends how close together the OEM valves are.

A fast road cam will yield good power gains, especially in the top end of the rev range. Don't go mad though a profile of up to 270 degrees will give the best gains without the engine becoming cammy.

The most popular power mods are induction kits (which are questionable as power mods but they can sound nice if that is your sort of thing) and sports exhausts with sports catalysts or decats.

To keep the car legal I'd recommend a sports catalyst rather than a decat.
The last mod should always be a remap as this will allow you to fully realise the power gains on offer from your mods. Turbo cars respond very well to remaps.
It's worth having a read of the articles on www.torquecars.com/tuning/ for more information on these mods and what the terms mean.

Hey Fred, glad to see someone else with a Sentra too. I have an 06 Spec V, and have been looking into what I could and SHOULD do to it. Here is a good post from the B15U forums... There are two mandatory mods we need to make due to design flaw by Nissan >: the exhaust manifold and butterfly screws. At least for the QRD25E, I'm not sure about the 1.8l. Hope this helps.
