Default Newb here looking for some advice

Hey guys/gals,

I'm in the process of purchasing chopchop's 2004 WRB WRX. I'm already looking for things to add to it. Apparently he has it lowered on espelir springs already. I'm thinkin about rims. What's the ideal specs for:

16"? (5x100, offset? width? tire size? etc.)
17"? (5x100, offset? width? tire size? etc.)
18"? (5x100, offset? width? tire size? etc.)

And how about body kits?

And performance? DP and EM... good enough?

Agreed. The guy who suggested it may have thought he was making a joke?

I'm not gonna bother with intake or BOV right now. Besides, don't intakes sometimes cause MAF problems? Any negative consequences with BOV?

Performancewise, I'm pretty set on DP and EM... and if I can find a very quiet exhaust, then catback as well.

What are you basing this on? There are approximately eleventy zillion threads talking abut the negative aspects of an aftermarket intake for WRXs.

I had a Cobb catted DP with a stock CBE and it sounded like stock. No louder.
I switched to an STi axleback to get a bit more growl. Even then, it's extremely quiet - more of a different note than an increase in volume.

^^^^ An intake and atmospheric BOV will make your car run like poo. This is a topic discussed to death, search. I'm sure the OP knows this already.

In my opinion, intake and bov's are just for sounds.

I got a K&N intake and loves the sound. I don't feel any gain from the intake though. So far, I've heard that COBB and K&N Short Ram provides the same MAF reading as stock? I'm not too sure though. And I think BOV's are ok if you have a catless setup.

If you're doing a downpipe, might as well get your hands on a Uppipe too.

Hope you enjoy your new car.
For wheels:
16" - generally for WRX sedans you can safely run a 45-53 offset but I would recommend between a 48 and 53. A 7-8 inch wheel depending on what tire size you want to run. I think for 16's a good 16x7 inch wheel (like raceface was selling) with a 225/50R16 would be great.
17" pretty well same as above. 48-51 offset and 7-8 inch rim. 215-235/45R17 tires.
18" - Get's a little mroe trick as your sidewall is becoming quite low. I just got some 18's myself and they are under 16lbs. I will be putting a 255/35R18 tire on it but would not neccessarily recommend it. Maybe a 225/40 or 235/40 or 245/35 would be my recomended sizes. If you ARE going to 18 I would find a light wheel because they can get attrociously heavy and you are paying a lot for rubber. 7.5-8.5 inch wheel would be good. 48 offset.

I would do an up-pipe BEFORE doing a DP. There is a pre-cat in your up-pipe that is beneficial to get rid of (and not advisable to run with a catless DP). A good combination we have done is catless up-pipe, HF Cat or catless DP and EM. For more info on our stuff www.rocketrally.com

As said above DO NOT get a BOV or Intake without getting it mapped and even then do it as a later mod.

Mods aren't cumulative...

But with a 'typical' Cobb Stage 2 setup (TBE, UP, Accessport) you can expect about 285 HP at the crank.

Go to www.cobbtuning.com if you're curious...

yeah, but thats the problem. How many people actually get a proper tune while running an intake? I'm willing to bet that at least 75% of the people who run an intake, do so for some time before they get a proper custom tune if they get one at all.

that's true, and unfortunately it's also how people come up with generalized comments like "intakes will make your car run like ****" "they suck" and so on...

<--- Is enjoying his APS intake. RR tune ftw

They can cause the engine to run really lean and detonate, which will destroy internals over time. Listen for the sound of marbles in a tin car when you're on the throttle.

every car reacts differently to intakes. But generally intake + stock EM doesnt give you performance gain. You might get, lean conditions, throttle response delay, rough idle and so on.

I ran my STI with K&N typhoon, and my EGT gauge never peaked above 850c. MY Plx wideband shows the same AFR graph as the stock. I might just be lucky. But either way its off the car.
