1. I want to keep the engine and the car, but there aren't many parts for the "Altime 2.5s" engine. However I found that the Sentra SE-R has the exact same engine. Can a slap on parts for my Altima that are made for the SE-R...say like headers and camshafts? Cold air intake?

There are those same items made for the 2.5: Headers,intake,pulleys,grounding wires,etc. are all available for you. just search

2. What do headers and camshafts do?

aftermarket headers will increase airflow from the engine due to better construction and ceramic coating that keeps them cooler than stock. cams would be the most expensive mod you could do besides turbo or supercharger. they will run you around $1000+ then maybe 300-700 to install depending on wo you can get to do it
3.If I wanted to plung in an EMS, would I have to modify my car first and then plug it, or can I keep adding things after I've already installed it?

what is "an EMS"? if you are referring to a chip of some sort you would have to remove your ECU and send it out to get tuned by one of the companies that does that work. or look into getting an S-AFC II

4. I wanted to put a Nismo 350Z dual catback exhaust, but there is only on exhaust manifold. (am I saying that right?) Is it possible to spread the exhaust into two pipes? If so, does it do anything to either boost or lower horse power?

The 350z exhaust will not fit on the altima. you can run a dual exhaust but it is pretty pointless. you are better off with the single.

5. What is a short shifter and what does it do?

Reduces the length of the throw of your shifts on a manual transmission. faster shifts = faster car


Thanks so much!
