My budget is around $6000 maybe a bit higher with the install. I really dont want to wait 5 years for the warrenty to expire because by that time im probably going to be buying an SUV anyways for the family. I want somethimg that does not require a lot of supporting mods. Just exhaust and intake but thats about it.

Thanks again for the input.

If you go with the vortech kit, you are fine with the stock clutch etc.
It does not put loads of torque out, so you don't have to worry about breaking things. If you decide you want to go a bit faster, fuelpump/injectors and E85 can put you into ~300whp if not more, and a quick pulley swap would just add more power.

The only thing you need to worry about is the drive belt. Run a quality drive belt, and check for wear every oil change along with checking the supercharger fluid levels.

Turbo will give you more power for less, but the engine with a supercharger just feels like you stock engine but.... more. Not overwhelming or kick in your pants torque, but just that extra bit to make it really fun at high rpm

he probably doesn't have e85 in Canada. that budget really only works for a mild supercharger.

Im looking at the vortech website and its about $6000 US plus tax, plus install. The turbo kits are a bit cheaper right?.

[Reaper]

no. except speedbydesign. theirs is REALLY cheap. but don't forget, gauges(600), tune, oil cooler(600), someone to weld the BOV flange on(75$?), new crash bar(150$) unless you want to cut it.

[KGB]

great thanks. I will take a look after work today.

I checked out the speed by design turbo kit. looks pretty sweet. how reliable or reputable is their turbo compared with lets say AVO or other competitors?

[KGB]

it comes with intercooler. is that an oil cooler. sorry im not good with cars :/

I don't think forced induction is the route you want to take if you don't know much about how your car works imo.

[KGB]

why is that? is there a lot a maintenance after the install? im not putting it in myself. Hence the research.

[Metabrz]

Buys car: want to drop 10K on mods before break in finished.

Not sure if taking the piss.

[KGB]

Meta. Im asking for advice. Not criticism. Not everyone is mechanically inclined. From what I have read, and this could be wrong. Most new cars have to be broken around 1000k. If you have advice as to how long I should wait please say so...

Alright @KGB here is a super basic diagram of a turbo system to show you how it works/what an intercooler is.



As you can see, the exhaust gases are used to spin a turbine. This turbine is connected to the compressor via a shaft and the entire assembly is commonly known as a "Turbo."

Since the turbo runs off of the exhaust gases, it tends to get extremely hot which leads to extremely hot intake air. Hot air = less power because the hotter it is the less dense it is.

You can see in the picture above the after the intake air goes through the turbo it goes through the intercooler. The intercooler is like a radiator but for the intake air. It sits in front of the radiator and is very noticeable (see the picture below). This cools down the intake air again and essentially gives you more power.



After the intercoller, it flows into the engine.

This is a very basic explanation of a turbo system. Quite a few supercharged systems also come with an intercooler.

I strongly suggest researching both systems on the internet to understand them better. You may not be mechanically inclined now, but all it takes is a little reading. Not only will it help you with your decision but it will help you a lot down the line when it comes to install and tuning. I know you won't be doing either of them, but it certainly helps understanding what's going on.

Generally speaking, a supercharger should be more reliable and less fuss because it is internally lubricated and does not have to tap into the engine oil supply. Also, boost tends to be more consistent and thus safer because it doesn't rely on a wastegate to meter boost pressure (again, generally speaking). In the FR-S/BRZ, the primary catalytic converter is located in the exhaust manifold, so that has to be eliminated if you install a turbo. Therefore, your likelihood of passing emissions without doing any funny stuff to the ECU becomes a challenge as well.

You can upgrade to a smaller pulley to run more boost, and if you max out the Vortech or Rotrex blower, like you could max out a turbo, you can always upgrade to a larger unit.

It is cheap because it is a ripoff of the Greddy turbo kit, thus reducing the R&D costs significantly. It is made in Taiwan.
