hi everyone, im new on here, i have just bought a 2001 uk spec wrx wagon, the car is really nice, its all standard. but the problem i found is it is not as quick as i think, the car doesnt really give a pulling like the sti... i mean it does give respond, but very slow like when u put yr foot down it takes about two second to have the speed, just wanna ask people on here is this normal for this car, if so what can i do to make it give me quicker respond like when u need it and push the foot on the gas abit it will pull it, what i would like is more torque,,, please advise me someone in here,,/?

Many Thanks

Better breathing would help with response.

Sort yourself out with an induction kit and an aftermarket big bore exhaust.

Wouldn't bother with an induction kit until you are at 350 BHP.

A well silenced decat (including the uppipe - 01 bugeye WRX has three cats) or sports cat exhaust with a sensible back box will keep it relatively quiet and unlock gains along with remapping.

Panel filter, Decat and remap is the cure for your woes

These will much improve response and also improve driveability throughout the rev range

thanks for all the reply, the car is come with a prodrive exhaust,do i need to change that as well, do i need to get the three decat, if so how much would it be, could i have the custom make one, or i have to buy a brand one, for the induction kit, shall i change now or later after the decat?? and do i need a ecu change as well after i change all this?? what sort of power i would expecting after all this change, ?? im sorry for all of this...

Many Thanks

Hi m8 i just fitted a k@n cold air typhoon induction kit to my 02 bugeye with ppp(prodrive performance pack) and notice a big difference, deffo feels like more torque and a bit quicker to get to the turbo kicking in.

john banks

Prodrive exhausts are nice. If it is just the backbox, I would still delete the uppipe and downpipe cats at least. Probably about £300 for both plus installation?

Induction kits are simply not necessary on cars on the standard turbo. Stick to what works and don't waste your money. The gains are either noise only, leaning out from reductions in airflow meter readings. At worst they filter poorly and suck hot air.

Once you have de-catted the exhaust, particularly the D/P and fitted a K+N pannel filter if you want to further improvement go for properly ported headers and matched up-pipe You will feel a noticable improvement.

As John-Harvey say don't bother with induction kits, try a good up-downpipe with belmouth and splitter and porting headers!
STI I/C gives slightly better throttle response!
I have also wrapped my exhaust from up pipe to rear section including turbo with heat wrap but I am not sure how much this helps in your case!

Good point Jim. Wrapping the headers, up and down pipe and turbo also helps add to the response.

Remap all the way - transformed my bugeye WRX, totally different car now (and no, you don't need a new ECU, an ecutek remap is perfect).

The only question is: Do you have a decat done as well

IvanLai

hiya,, thanks again for all the answer, i have just bought the car for two days, its a 2001 uk spec wrx wagon with 18 oz alloys and prodrive exhaust(im not sure is it just the back bow, how can i check) 32000 mileages what do u guys think this car worth, just wanna check did i get a right price?, please could someone can give me full advise as in what to do next and where to go for the stuffs and how much so i know how to do it, im new to the subaru so i know nothing about it, when u guys say decat, is it mean i can get a full exhaust system custom make? if i get all three cat, what will the power like? torque and bhp,

Many thanks

I wouldn't start asking about price now you've bought it , you will find a range of prices that people place on the car, there is no book value when it comes to scoobs, its a free for all.

Decat doen't have to be a custom job, there are many brands that sell complete systems and ship to your door. Expect to pay between 400 upto over a grand for a full turbo back exhaust system. Ideally wou would want a 3" system, although for your power output a 2.5" will be fine . When you decat you will release the Impreza burble and wake the dead

Once remaped i should imagaine power output will be between 250-265bhp, but thats just a rough guide i stand to be corrected

Around £7-8k for a private sale would be about right, perhaps a tab more.

To check the exhaust get under the car and see if the pipe are "straight through", without any bulges in them. starting at the back you have the backbox, then a centre section (OE pipes have a resonator in them), then a short cat pipe about 2 feet long (this may still have a shield on but nothing inside if it's decatted), then you're up in the engine bay so you may not be able to see........

Taking out all the cats will give you ~20-30bhp extra, with a remap ~70bhp extra.
