Basic Car Modification: What to do and what not to do
I will split this section up into parts: Basic bolt ons, engine work and forced induction. Each section will tell you what to do, what works, what doesnt work and what not to waste your money on...
Bolt Ons
Induction:There are two basic types: Cold air induction(CAI) and what's commonly called as short ram intake(SRI). Both obviously have their differences, advantages and disadvantages. First, let's start with the regular CAI.
CAI is a long ass intake tube that places the filter in a remote area far away from the heat of the engine so that the motor can inhale some cooler air. cooler air means denser air...which ultimately means more air for your motor. now you may as, how is this bad at all? well it's not...but with this, u lose throttle response when compared to a short ram..and u also lose high end power as your engine has to work harder to suck in that air(since the filter is so bloody far away). there is what's called ram air...which is basically a cai but there is an air passage placed outside of the enginebay. the air is forced into the air passage and the intake sucks it. so you get the "air blowing in and intake sucking the air" effect....which means the movement of the car helps the intake. This is by far the best design but choosing a location to put the air passage is a tough decision. it must be placed in an area where there is the most positive air pressure(positive meaning air is flowing into there..rather than being drawn away).
SRI. the short ram is a stick with a filter at the end. this intake tube isnt nearly as long as the cai is and the filter is placed in the engine bay, usually beside/behind the battery. With the short tube and closely placed air filter, the engine has good throttle response and high end is much improved. the pitfalls of this is that it sucks in all the hot air produced by the engine! there are ways to get around this described in my other section: here.
