Default Question about Turbo

Hi all, im pretty new at this site cuz I just got my new 02 silver WRX. I love the car, still under 1000 miles, and still completely stock. My question is, is there any way that you can boost the turbo to kick in earlier than 3000-4000 rpm for a cheap price? I heard from my friend you can pay under $100 to get the boost, which I kinda doubt.

Also, I feel very weird on the brakes. I used to drive a mustang, and the brakes are quite responsive. However, on my WRX, I can press the brake about 1/4 of the way and it still wouldn't brake until I press harder about half way. Any of you guys experiencing this?

Finally, any other mods for a reasonable price that can make this car faster?
Thnx.

Make sure not to rev above 4,000 rpms before 1k miles. You can buy a manual boost controller like a Joe P. or a Hallman. They run around 50 dollars and allow more boost and earlier spool up. If you want the Joe P., let me know. I know Joe P. himself and he can ship it right to you. -KB-

oh sweet, thanks for the reply.
Im actually quite interested in the turbo timer. So $50 shipped? I haven't done any research yet on this mods, but im really interested. How much boost will the turbo get? Anyways, e-mail me at [email protected]

Also, I understand that I shouldnt rev it up higher than 4000, but sometimes on gear one I got carried away and go until 5000 rpm Thanks for the advice.
How about the brakes?

It's a manual boost controller, not a turbo timer. The TT runs your engine after you turn off your car to help the turbo cool down before shutoff.

the brakes are normal. i think all subarus are like that.

if you get a manual boost controller you will probably need a boost gauge to make sure you aren't boosting too high. i dont know alot about the WRXs so i cant say a whole lot about tuning them...


edit: also, welcome to the i-club.

You can get an Autometer gauge for around $60 and along with a few fittings you will be good to go.

S-WRX - Welcome! First, you may find some of the answers to your "power" question by searching the WRX and the Factory Forced Induction forums. And you may find answer to your brake question in the Brake/Suspension/Wheels/Tires forum. It's also more appropriate to ask the questions there.

But to answer your question briefly... If you don't want to mess with a MBC and the boost, there are 2 things many of us WRXers do first. One is a K&N or ITG filter, which seems to help the turbo spool a bit faster. Another one is to remove/cut off the air intake silencer. I did it last weekend, and can feel real improvement in low end torque. You'll find lots of posts and instructions if you search for them.

As for your question about brake feel, it's normal what you see. One easy and cheap improvement is to get stainless steel braided brake lines. But the most effective one seem to be swapping out the two-stage brake booster for a single-stage one from early 90's Subarus.

I've done quite a bit of searching for some of the "first-to-do" mods, but I'm a bit confused.

I've read about replacing the filter with a K&N or ITG, and I've read about removing the air intake silencer.

I've also read about installing a High Flow Cold Air Intake.

Aren't these two mods (replacing the filter; removing the silencer) essentially the same thing as installing a HF CA intake, which I assume also involves removing the silencer?

The latter is a much pricier way to go and I'm wondering what the benefits of this approach might be that justify the cost.

In reading about one particular HF CA intake, the manufacturer recommends a Unichip for optimal results. I don't know if the intakes from competing companies also require a Unichip. They don't mention it and I wonder why not?

I'm worried that starting with the two basic mods (replacing the filter and removing the silencer) are really Band-aid solutions and that I would be better off jumping in with the HF CA intake and Unichip (assuming I could find someone to tune the car after I've installed the stuff).

Mambo Kid - but the K&N only costs like $40, and the silcener mod is free and takes at most an hour to do. To me, it feels like a good little investment, and if you look at it, the air will now comes from the fender (good!), go through a short pipe into the airbox, up through the filter to the air-flow sensor. Only a couple of turns, but no major constriction anymore, which in my opinion, is not bad.
