Being 18 is no excuse! I bought my '96 when I was 17 and I've done all the work on it myself. The intake you speak of is cake, if you get the honda civic intake made by spectre that they sell at autozone then take out the stock airbox and accordian tube (everything before the throttle body) and install the intake kit. Take a browse through the gallery and there are plenty of pics and I have a few in my sig links too. For the breather on the valve cover you can either put a little filter on it like I did or run a tube to the new intake, the spectre has a port for it. This should at least get you started. btw, the search button is your friend, all of this info has been covered before ...repeatedly. Any more Q's feel free to ask.
try napa or something close to that(parts plus-lordco) and ask for a early 90's civic short ram intake. You may have to trim it abit to fit right. As for the vent hose to the old intake you can either extend it out or by a small breather cap. its a really easy thing to do so don't freet over it.
here's the final product.
Yah it seems easy but you guys are talking to me who has no clue about anything lol, SO when i get this early 90's civic ram intake whats the next step? btw it looks wicked, how much did it set you back?
once you have it in your hand simply remove the factory air box, u'll need a torx bit for the screws. remove the clamp on the tube on the throttle body. Install new intake. it would be wise to support the filter with a strap so it doesn't flop around, as in my pic. As for sound difference yes, performance yes but not a drastic increase, hardly noticeable.
Read through the service manual to get an understanding of how your car works, and then you'll just have to get your hands dirty. Or find a freind who knows what he is doing and pour some beer into him!
