Default introducing myself and need some answers :D

hello everyone, just want to introduce myself; im a new subaru wrx driver and just curious about something.

ive been told from my friend that usually when you tune a subaru, you go by stages. i just want to know what what does that mean. well from what ive been told so far, i know that by adding more performance part, you go up the stage. but how do i know which stage im at, and where to begin or end.

--also im really interested about getting a open wastegate. dont know where to start of getting that, bc i want to be a txs stealthback, will that fit with the whole open wastegate project that im doing.

ps. its a wrb wrx wingless. with a cool CARBON FIBER EXHAUST SHIELD. lol doesnt really do anything but looks cool to me. thanks guys,


duke

its always a good idea to fill out your profile so that people know what they're dealing with. as far as stages go, this is more of a marketing scheme for aftermarket performance stores. but for starters, stage I is an ecu tune on a stock car and stage II is basically a turboback exhaust with a tune. a good way to get started in your research is here

good luck.

All you need is a special up-pipe for an EWG setup... oh, and a tune afterwards.

Before you do anything to the car read the forums. I'm a subaru noob as well and the one thing I've learned is imprezas are sensitive to mods. If you install some random mod, the fuel/air ratio can change, then you car start to run lean, and your engine eventually gives out.

It's not random, it's actually very straight forward. It's just that a lot of people here that claim to know what they're talking about actually have no idea and tell noobs they will blow their motor if they breathe on it the wrong way.

The only mods that will change your air/fuel ratio are those that affect the air or fuel. Changing to a larger MAF housing without telling the ECU means you will have more air coming in than it thinks and you will run lean. Switching to larger injectors or crushing your fuel pressure regulator without telling the ECU means you will have more fuel coming in than it thinks and you will run rich. That's as complicated as it gets...

These cars are no more sensitive to mods than any other turbo car, but turbo cars in general are a bit more sensitive than NA cars.

on the "stages" front, you need to read this:
What is a Stage 2 or Stage whatever package?

When I spoke of sensitivity to mods I was thinking of naturally aspirated (NA) cars compared to turbocharged ones. I should have clarified that.

I'll have to say one of the most affordable mods that comes to mind is replacing the stock air-box with intake. Before you think about even doing that read this intake FAQ...

http://forums.nasioc.com/forums/showthread.php?t=477393

After reading this, I decided to keep my stock air box, but changed the oem air filter for the HKS hybrid drop-in filter instead. I've noticed a better throttle response and my MPGs have gone up a few points

Which are in some cases nothing more than expensive, fancy paper weights.

My suggestion to the OP, don't make any decisions on anything yet. Start with the Stickies at the top of the forum, specifically the Unabomber's Manifesto, wherein is contained an Engine Management FAQ that will give you a GREAT starting point. It will also help get you in the habit of searching before asking questions, as just about anything you can think of has been asked before, and answered in great detail. Why wait a day for random answers when FAR more results can be found in a few minutes?

You should also look around your regional forums and see what tuners are local to you and what software they use. If you can get professional custom tunes, an AccessPort can be one of the biggest wastes of money out there, and a blanket statement as a suggestion to buy one is not very good advice.

Good luck and enjoy!

You dont need to go by stages. It just makes things easier to tune for and market (and brag). Welcome from another new member!
