NEWBIE ? car anatomy

lets start out by saying i hope you dont think i am a complete idiot by asking some of these qeustions. I know the answers to some but not completey. what i need is somoe who knows the anatomy of a general japanese import car. Like i need to know the following and what ever goes with it such as what do they mean by catback exhaust, what would go with that would be the anatomy of exhaust and common exhaust upgrades, so now that you know what to answer here is my wall of qestions; difference between turbo and supercharger, different aspecs of forced induction and anatomy of forced induction, anatomy of a common engine jap import, like how it actually works, how gas gets to engine ect... blow off valve? how does NOS work, the full anatomy of suspention what are defferent suspention mods, and so one for every part of a car. what i need is indepth info, like a distcription on eac part of each part of the car. Besides the interior. PLEASE HELP

the "anatomy" of a japanese car is essentially the same as the "anatomy of an american car. (minus the cylinders of course)

A motor is a motor. They all function basically the same. (Put aside rotaries)

I'd like to answer all your questions, but you're throwing out too much at one time. Try asking one question at a time; and we'll try our best to answer. Try to be as specific as possible.

Anyway, here's my shot at it (everyone feel free to correct me if i'm wrong)

There's three basic things that get the engine running: Air-Fuel-Spark

In a naturally aspirated vehicle (non turbo/non supercharged) - Air will be sucked in through the intake->pass through the throttle body (we can explain this later on, i'm trying to make this as basic as possible) -> goes into the intake manifold -> and is combined with fuel (through fuel injectors/carbeurators, again, can be explained later on) -> and ignited by spark (spark plugs) -> the energy from the ignition will move the piston back down -> exhaust gases will exit the motor -> through the header/headers-> through the catalytic converter (won't apply to most older vehicles) - > and all the way back through the exhaust.

So when people refer to "cat-backs" they're referring to the exhaust piping from the catalytic converter, all the way back.

It has all that schnazz there.

thank you for the help, so what your saying is that when people refer to catback exhaust systems that means there is a catalytic conveter which usually is not included on stock rides? And my next qeustion is going to be from the very start of the car. Correct me if im wrong (which i probobly am) When you hit the ignition it shots the piston down and lets gas in, then the piston go's up in its power stroke and pushes exhaust out pushing the exhaust through the catalytic converter (which takes all the axsess air out?) and when comes ... and correct and add as needed, thank you alot

Catalytic converters DO usually come on stock rides, as they are required for emissions.

People prefer catbacks because the piping is made bigger from right after the catalytic converter, all the way to the end. Bigger Piping provides horsepower gains.

Some people prefer just to change their muffler for the sound; which doesn't not prove any gains, because the piping from the cat and beyond, has not been enlarged to provide better flow. The bolt-on versions of the "muffler change" are usually referred to as, "Axle-Backs" or "Rear Sections". But most of the time, they're just welded on.

Uhh..

Enlargement to a certain point, if thats what you're getting at 383PhoenixAm

Of course, oversized piping for the application would result in a serious amount of torque loss.

If that wasn't what you were getting at, then hey, more fun facts for Silvia15

Better.
Don't want to give anyone the idea that you should run around with 4 inch diameter pipes and say it makes you faster.

Well maybe if you had a Twincharged W16 :icon16:

Haha.
Sorry, I forgot about the millionaires.
