Default Welcome to subaru life

Hey everyone,

Thought I would join and say Hi. My name is Alex and my girlfriend just bought a 2012 Impreza Sport.

Its a 5 speed and sedan so I can't see myself avoiding doing at least some small touches to it. Until the warranty is up I'll assume it's untouchable performance wise. First thing I want to do is a short throw shifter and hopfully shorter in length as well. I'm not sure if this is a subaru thing or not but I feel like I'm driving a truck with an old notchy shifter compared to my other car.

This car is replacing her 03 1.8 Quattro and I'm hoping it'll be better on fuel and repairs as well. I would have gotten her to join, but I'm going to be doing most of the work anyway.

I also own a 97 Miata with many mods to it, an 06 Silverado Hybrid and 00 TDI if you have any questions.

Cheers

Welcome, just picked up a '13 Impreza Sport recently myself. The short throw shifter & bushings + STI rear sway bar seem to be the go-to mods right now. The below thread should point you in the right direction

Thanks for the info.


Hopefully there will be some sort of turbo/FI kit available when my 60,000km are up. I know the 2.0i probably can't handle much, but 6-8psi should wake it up and still allow for superb fuel economy.

Welcome! I like the sport package on the Impreza's. As far a FI for it I would just trade it in on a WRX when you are ready for that.

Not a good idea.

Much better idea.

I keep on reading that over and over and over...
The new 2.0i apparently aren't a good idea to boost by talking to other Subaru owners but no one has any facts about it.......the 2.5i are horrible on gas in comparison and the brz has the same 2.0i doesn't it?

Also the BRZ has been turbocharged with a kit with good results already as well.... Not sure why everyone is advising to simply trade it in for the old 2.5i.

Not saying I'm going to throw 20psi at it but a ~10psi MAX kit could actually help it along.

I guess time will tell as we see more people experimenting with the BR-Z/Impreza

No one has said trade it for a 2.5i, they've said trade it for a WRX. Turboing a NA motor makes less power than a WRX, and they don't tend to last very long. An AVO turbo kit for them is $5000, will de-value your car, and has some likely hood of you blowing your motor in 10-15k.

The money isn't well spent. Subaru makes a turbo car and NA car for a reason. You aren't going to duplicate the reliability and power to be found from the factory.

It's all about compression ratio. Your N/A is 10:1. From memory, a turbo subaru is 8:1. The BRZ is 12:1. The only guys doing BRZ forced induction are limiting to 4psi. You'd have to do about the same with your N/A. The brz got 50hp.

So let's say that it costs you $5k to put in a turbo system. You are still nowhere near stock WRX levels and are running the thing relatively dangerously. Can you get more power? Sure. Agressive cams, low compression forged pistons, forged rods and then put on your killer turbo and engine management. Of course, $12k later, you're looking in the mirror muttering "idiot". Why? Because you could have sold your Impreza and bought a WRX for less.

So that, kind sir, is why everyone on this nasiocs will tell you to just sell the car and buy a WRX. It really IS cheaper than trying to build up your car.

Not that I am suggesting he boost his impreza but a turboed brz running e-85 isn't half bad.

Thanks for the replies, I guess the everyday fuel economy part is the nice thing about the 2.0i in my Impreza and I want to keep that.

10:1 ratio is certainly better then the BRZ and 6psi doesn't seem like it would be a problem.

As far as fuel economy... my Miata actually gets better fuel economy driving in the same manner after I built and boosted it so I guess that's why keeping the 2.0i was of such interest.

most of the turbo kits I've seen are 5-7, Vortech has a 9psi option, and I recall reading about tests in the 12psi range.
