Hello fello G lovers. There aren't many suggestions involving power or performance mods regarding the sedan.
My Mods so Far...
MD Plenum Spacer
Stillen Cold air intake system with ZTube.
Stillen Engine Torque Damper.

I dyno'd 251whp. Wanting to get it up to 285 or 290whp. I would be satisfied with that. 300whp would make my day tho.
Not looking for stupidly rediculous power. Just A nice gain without goin broke.

 

Oh yea. Fastest 1/4 was a freakin 14.4@100mph. Wanting to get to 13.7 or 13.8 if possble.

 

First breather mods then a tune to tie them all together. At least that's what I have read

 

Ok. Breather mods consist of what? Intake and exhaust right. So my next step would be some type of exhaust upgrade. Any suggestions on the sedans

 

Performance wise, the only difference between your sedan and a coupe is the exhaust options. 290whp is possible on a generous hub dyno but don't expect to hit those numbers on anything else with just bolt-ons. Fully un-restricting both the intake and exhaust systems, cams and an aggressive tune MAY get you close. Upgrading the fuel system will help a little also.

EDIT: Why is this in the feedback section???

 

I would check to make sure that your car is able to be tuned before you go too crazy with the mods, you'll need to replace the OEM cats to make any more power and that will require a tune.. early 03 sedans still use the old style ECU and aren't tuneable with Uprev... See the attached picture and check which one you have

 

Give the noob a brake lol

 

^^Good point, forgot about the tuning with the 03's.

Check out some of the builds here: http://my350z.com/forum/na-builds-498/. That should give you an idea of what to expect.
