Hi everyone, I just order my Blue WRX yesterday, so, what mod should I do first?

Someone said, after intake and exhaust, then I must have an air fuel controller, is it true?

What kind of exhaust has good performance but also quiet?

Thanks.

The first thing you should do is break in you engine and transmission. Drive your car for 5,000 miles before you start throwing money into it. Take it on a couple of road trips and drive it hard after the first 1,000 miles.
The WRX is already very fast and you should wait until it starts to feel slow before you start modifying it. The only thing I would do (and did to my car) before it is broken in is drop in a K&N panel filter - P/N 33-2031-1.

I have 6,600 miles on my car and only minor plans to make it faster. I feel the car is getting faster on its own as it breaks in and I get better at driving it. I'm thinking of just saving my money until I can afford the APS/Cobb tuning Stage 2 kit. 320HP is nothing to shake a stick at!

Good luck with your car! What options did you get?

Hi Platinum!

I will pick up my WRX on Friday and I am so exciting about it! :)

My friends said I should do something which make my car last longer, like turbo timer, blow off valve, gauges, oil cooler and etc...

Those stuffs will already cost me a lot! :(
So, i think I will not do anything to make my car fast till I can save back enough of money.

I live in Canada, the Canada 's WRX comes with full option (include that little spoiler and the only option is automatic), so, I think it is fully load except the auto.

Someone told me the stock turbo can hold max 330HP, isn't it?

Yep but when you have 330 horses is pushing it a little on the stock turbo but whenever you have that much power you should consider upgrade your transmission.

330? No way. Stock turbo is pretty much maxed out as it is. I'd say up to 275 MAYBE and that's pushing it. First mods you should do is to improve breathing. Get uppipe and donwpipe. Exhaust is not really all that necessary with stock turbo but if you get a new turbo might be a good idea. You'll get the most improvement removing all 3 cats. Also, a boost controller is a good investment. Blitz SBC-id is my personal favorite but HKS, Greddy and Apexi also have them. This will allow you to hit close to full boost in 1st gear and keep boost constant. It also improves response and minimizes lag. After that you really should invest in a bigger turbo. The stock one just doesn't cut it.

even before turning up the boost, you should at least get some gauges (i.e. boost and EGT). you should know what your baseline is first before cranking it up.

wihtout a doubt, the first mod should be wheels and tires. the stock ones suck all around. i CAN NOT chirp my rex, and have NEVER heard it with 4200 miles and counting. after all, it is the only mod that actually connects you to the road!

SERIOUSLY!

Personally, I think the first things should be strut tower bars, tie bars and adjustable sway bars. Suspension would probably be next along with wheels, tyres, big brakes(which usually only fit in 17 or larger wheels). Once your car is able to handle the power(notice all the initial mods are handling performance), get power to match. Removing all 3 cats and replace with big mandrel 3" will get you loads of power, but it might be illegal(actually it usually is, but it depends on how nice the cop is). I've spoken with a Subaru man(from headoffice in To) and he said with the appropriate intake, exhaust, the car is pretty maxed at 280hp with 22psi. And he agrees some of the Subaru parts suck, like the house BOV. Blue, whereabouts in CAN are you from?...As for tranny upgrades, depends on how much power you want, but a dogbox is rather expensive but probably needed if you want like 400hp. AFC is not really needed if you get a new intake and exhaust, but if you up boost a bit and get like CAI, you might want to consider it, depending on how many psi you run. As for CDN specs, there are some Subaru dealers that specialise in modding for rally and street. Stock CDN gets spoiler but not too many other options. Some dealers offer leather WRX seats, WRC decals, etc. Actually, I live in CAN and I'd prefer it if Subaru didn't give that spoiler and just dropped the price a bit...at least I can get an ALU wing like an APR adjustable and not have 4 holes in my truck to allow good ol' Montreal snow and salt in.

I'd say listen to PlatinumWRX, his advice is very solid. Let the engine break in and burnish off the rough edges, then think about some modifications. My personal opinion is that performance money is best spent on improving handling and driver education - the car is pretty powerful bone stock. In any case, give it at least a few months, then consider your options.

handling on the stock rex is already outstanding! the only thing that would need to be changed would be the re-92's.

Yes, the stock tires suck. I had a scary braking/handling moment yesterday and I blame the tires, it had nothing to do with my driving skills :D

Hi schischwein and guys:

thanks for all your advise. :)
Yes, I think the stock tires are really bad, because I tried it before.... The RE92 is ok on a dry road but never drive fast when in a rainy day, it makes you feel like drive in winter without winter tires.

Ok, I think now, the first thing I have to do is..... (pls don't laugh guys :) )
Learn how to drive a manual.... I am new with it, so, do you all think I can ask the dealer teach me how to drive it? If not, I think I should ask my friend to help me to pick up my WRX.... Then learn.

I will pick up my car on next Wednesday, I am so excite man! :)

If you can, try finding a friend that has an old car to learn how to drive a manual. I learned on a friend's old accord and so he didn't really get upset when i killed it or grinded a gear or two. Just my $.02

Definatly find someone with an old POS car that they don't care about. As for performance mods, I would wait until it is broken in before I do anything. I would get a turbo timer though but that isn't really a performance mod right?

Blue, how did you test drive the WRX if you don't drive manual(auto version?)? As everyone else has said, find someone with a beater car to practice for a few days before you take your baby home. As for bad tyres and handling problems...some race schools purposely start learners on crappy tyres so that you learn the handling of the car and are forced to drive well(ie put every technique to good use) since the problems of the car are amplified. Look at formula 2000 racing, those cars have little skinny tyres that look more suitable for an Echo or some other death trap. But in the long run, new wheels and tyres are a must.
