engine help

I want to do something to my sohc engine. The thing is I'm not that knowledgeable on it so I just want to do simple upgrades. What would you suggest? I've heard of cam sprockets and stuff but what doesn't take a lot of knowledge to install? Also please tell me what each thing does as well, thanks.

the easiest thinggs are..


a full tune up..__===
spark plugs..
wires..
cap rotor..

and then a CAI....cold air intake...you can buy one at a over priced store or buy a K&N cone filter and make your own tube...theres a site showing how to ill have to look for it..

upgrade your injectors..
cam..
exhaust....do a cat back or header back with like 2.25 or so
header...

im not sure on what your car is like since mine is 10 years older and not fuelinjected..

k you dont have the knowledge, do you have the tools ?
i say put a intake on and a cat back exhaust, these will be tranferable later if you decide to do a motor swap. simple stuff to do first

well I have a cat-back and CAI already, but what about a cam sprocket, what does this do?

cam sprockets make it so you can adjust the cam timing advance or retard.

get a header, they are not that hard to install. you can also get a msd and like a blaste coil. also you can do a tune up like dutch boy said, buy some denso iridium plugs, some accel or msd wires, get a external msd coil cap so you can run the blaster coil. all these would be easier than installing a cam gear because to install a cam gear you gotta take off the timing belt and that not that hard but if you never done it before then its gonna be hard.
