Default Modifying a 1998 Honda Civic?

I just purchased a 1998 Honda Civic Ex (non v-tec) that has 155,000 miles. The car is in pretty good shape with no rust. Engine seems to run fine. I was looking into throwing some performance parts at it such as a Short Ram Intake (cold air), headers and the pipe that connects to it, high-flow catalytic converter, and maybe some faster timing such as better spark plugs, wires, distributer/rotor, and ignition coil.

My dad says that my car is not worth modifying cause it has 155,000 on it. He says that anything you do to make your engine run faster will also cause it to wear more. I have to disagree with this, because the parts i'm looking at simply make it run more efficient such as the SRI, and Headers etc... I'm not sure if the timing would be harder on the engine.

I'm pretty good with cars, but i'm no expert. What do you think?

Also would anybody have any recommendations on what brands to purchase, and specific parts that will help me get the most power out of my civic without damaging it.

It also has a 5 speed manual transmission

Sorry to burst your bubble, but when Honda created this car it was already at its peak for efficiency. Plugs, wire, ignition coil and distributor do nothing for efficiency and performance. All they do is guarantee a spark that may or may not be better than stock. All headers do is shift the power curve of the engine. No horsepower there. Cold air intake is baloney. You already have a cold air intake and messing with it will definitely throw off your performance curve. Your intake is already tweaked by Honda. High performance catalytic converters mean more volume and maybe a cause for smog inspection failure. Higher volume cats on a small engine means the catalyst may not get hot enough to do its work. A larger cat back system may improve exhaust scavenging. There really is only two ways to get more zip and bang for your buck. I would only do one and not the other. You can change your cam and while you are at it, change your head to get larger intake valves. The other is get a chip to change how your engine uses fuel. One suggestion is if you are going to be a serious tuner, start by doing a dyno run on your car to get your front wheel horsepower. Then every time you change something, do a dyno run. You will find if you buy after market cold air induction systems and trick intakes, either nothing happens or you lose HP. You can always take the "trick" stuff back with proof it doesn't work and get your money back. By the way, tell your dad I would agree with him if it was an American car, but a Honda is just getting broken in at 150K.
