I just bought a 03 350z, all it has is cat-back Megan exhaust and AEM cold air intake, other than exhaust and cold air intake, what is the first few things that should be done....

 

Depends on what it is that you want to do with your car. Ask yourself these questions:
- Are you more interested in looks or performance?
- HP or handling?
- Is it a DD, weekend warrior, show, track, or auto-x?
- Long term plans, NA or FI?
- Are you made of money?

Once you know what you want to accomplish, then you'll know what questions to ask and start to come up with a plan.

First thing I'd do, if you haven't already, is do a complete fluid change.

 

im doing fluid change this weekend....
mainly performance but minor looks and handling, and daily driver

 

want to change wheels and eventually brakes, but for now, just go with performance

 

Next you could get a plenum spacer which is the only 'cheap' upgrade remaining. That shows great gains. Then of course you could get cams, tune, etc. If you search, you will find a lot.

 

would headers and high flow cats do much?

 

Ok I'll b the first to say it. U need to search this forum for every question u have and if u can't find a answer then make a thread about it

 

sway bars are the best bang for the buck in performance.

 

agreed!!!

 

your referring to handling, i want to do some handling but focusing on engine at the moment

 

Motor-wise?
Boost.

Everything else is just toys.

 

dont have the money to go for boost yet, that will come later though. I just have to do somethin b/c i had a 383 stroker z-28 that i sold and a stock z just aint cuttin it so far

 

Hate to say it... but assuming you had a later LS1 camaro... you could MAYBE match a STOCK one with full bolt-ons.

 

match a stock z with camaro and boltons or stock camaro with z and boltons

 

it would take more money to put on bolt ons to match the z28 than it would to just get a supercharger..

 

+1, they really decrease the body roll

 

a fcking Z with FULL bolt ons isnt in the same park as a 383 stroked camaro. Why is this thread not locked yet? Please use the fcking SEARCH function that is on this site for DA questions like this match a stock z with camaro and boltons or stock camaro with z and boltons

 

My vote is put the stock air box back on and replace the Megan exhaust

 

fixed

 

i sold the camaro because it was horrible on gas and i just started college, it was a fun car to drive but had to part with it.
