Hey guys i have a question.. I havent been into civics for long time.. Long time ago i rember there were turbo kits and supercharger kits for lx civic. i cant find anything.. just for the si

A turbo kit will be easier to find for the car rather than a supercharger. You can piece together a turbo kit. With a supercharger, you really need to find a replacement intake manifold (that is, if you are talking about the JRSC Eaton "Roots" style blower)

How much money are you looking to spend, and how much power are you looking to get out of all this?

EDIT: By the way, when you start talking about engine parts, you should really search for a turbo kit or supercharger kit for that motor, not the chassis of the car.

 

for an I4, I'd heavily recommend a turbocharger over a supercharger. Superchargers create a small load on the engine since they run off the serpentine belt, so they take a little bit of power to make power; that power loss is more than made up for with off-the-line linear boost, but it's still taking power to make power. A turbo, on the other hand, takes the ~33% waste energy of the exhaust heat and uses it to create boost, effectively making power "for free".

 

I just bought the car had it 2 days ago.. I dont no what kind of boost can a stock motor handle? Is it 50 state legal ? I had to ask..


The price depends how much power i can get..

 

Being 50 state legal entirely depends on what you get (what brand, what kit, etc) and the tune. If you live in CA, your options are pretty limited.

As far as boost, boost pressure isn't a great unit of measurement for the fact that it changes too much. For example, I'll use my straw analogy: 10psi in a 1' straw is a lot less air than 10psi in a 6" sewer pipe of the same length. The same goes for turbos: a Mitsubishi 14B turbo creating 10psi is going to flow a lot less air than a Garrett GT3076r creating 10psi. As a rule of thumb, you want to go by power, not pressure. Your engine (bone stock) can handle about 200whp before you need to start looking into building the bottom end.

If you live in any state other than CA, you can be sitting at around 200whp for $2,000-$3,000 if you piece together your own turbo setup. Note that in 95% of the cases, a custom turbo setup isn't going to pass a strict emissions inspection.

 

How good is the stock automatic ?


I was wondering how much boost can the motor handle. Long time ago i rember hearing something around 5-7psi but it was long time ago

 

The stock automatic honestly isn't that great for higher power levels; it's better than most stock automatics, but it's just not going to be able to handle the increased powers. One of our old moderators turbocharged his automatic civic hatch; I believe he went through three automatics before swapping in a manual.

And again, boost is irrelevant; your motor can handle ~200whp regardless of boost level.

 

Can I turbo my 2018 civic lx-p coupe

 

Anything is possible with enough time and money.
