  What are your 2.5 (or 3.5) performance mods?


Ok so I haven been searching for ways to get more and more power out of my 4banger and wanted to sort of collab with every1 to get their opinions and ideas.

Yes I know the first mistake I made was getting a CVT tranny and second getting a 2.5. I got a 2.5 because it fit me financially and I ended up getting stuck with a CVT because I wasn't patient and the stealership were being dumasssssssses.

So let me list my mods:
- Fujita WAI
- SentientByDesign Grounding Kit
- Custom Axle back (dumped muffler just for a bit of sound)

I really would prefer to get a cat back exhaust but for the price I think I would be better going another route.
After I receive my headers this weekend I plan on then purchasing the QTP electric exhaust cut out first discovered by hussain. Seems like a better route so I can open and close it on command and get the extra power when at higher RPMs for better exhaust flow and more top end[?]
To make up the for loss of torque with the headers I want to then get the Stillen lightweight pulley so it evens out the powerband.

I've been reading about other mods like transistors I wire on my air sensor and throttle body bypass mods that both have their ups and down.

After coming across a thread about the sentra se-r specv and how they have a different intake manifold, cams, and ecu mapping to bring the power up to 200hp. So my thoughts were why don't i hit everythingnissan.com, order some se-r cams, and drop them into my motor with a bit of tuning? Wouldn't that hopefully bring up my numbers?

Then of course invest in a bullydog triple gt tuner.

Thoughts? Opinions? Feedback? Ideas?

I have an Injen SR Intake
Stillen Headers
and SBD Grounding Kit
Saving up for Greddy Ti-C right now and going to have a custom downpipe made.

The Stillen headers actually brought back some low end that the intake took away I was quite happy

sounds about the same as what i have. waiting for a cut out to have the headers put in. im glad the headers make up for a bit of low end power since i do have an intake.

any thoughts on sentra se-r cams in the coupe?

really? i really don't know any1 else that has them to get feedback but i looked up race ready performance and noticed they only have the cutout but not the exhaust piping. i'm guessing i could get a muffler shop to make me one?

got a 3.5 6spd injen intake, short throw, magnaflow exhaust, y pipe, trying to save for the pulley and bullydog but just had a baby 2 months ago so you know how it is, unless anyone wants to donate, think of it as charity.



Injen intake, short throw shifter, custom magnaflow exhaust using 14158, y pipe, have eibachs just to lazy to put them on
