Hello i just bought a 03 wrx and have a few ?...
im looking to get exhaust, bov, and cai can someone point me in the right direction as to what items are good. i lost as far as wrx's due to just getting it but i want to get pointers and tips from other owners as to what setups are good and work

thanks in advance

hyper wrx

 

don't bother with cai, or with bov. cai has to be done carefully to preserve the way the computer interprets MAF data. the stock bov is plenty good until you start doing other mods to the turbo system.

i just got a my03 5mt sportwagon, and the FIRST thing i'm going to do to it is get some gauges going. 1) boost and 2) exhaust gas temp. they're both very important if you're ever going to start fiddling around with it.

thanks for the info


has anyone done work to there 03 wrx as far as bov,cai,exhaust

 

YES. NO BOV! NO COLD AIR. Remove the silencer and be done. Get a flex up pipe, turbo will spool MUCH faster. Great difference. Then turbo back exhaust followed with a reflash. Should be happy happy! for a while. dont rip the gears too much though as the tranny is not too good.

 

Best bang for the buck part I would suggest would be an upipe to start. That will feel good in itself. Try that out for a while, and if you feel the need for more power, then follow that up with a downpipe and catback (turboback) and then a good tune. As far as Intake and BOV go, spend that money for the parts mentioned above. BOV and Intake = money spent for no performance gain.

 

don't waste your money on a cai.

As for the bov, again, don't waste your money, but if you want the sound, then waste your money and get it

 

up pipe+turbo back+tune ! ---> [YOU!]

 

no way its plenty fast in a strait line

the biggest improvement for the car by FAR (i have a FMIC VF34 link ECU interior ..............ect)

was teh rear sway bar

 

check out some member's rides and the review section for parts reviews, but cai's and bov's are pretty much asthetic upgrades only=make engine bay look pretty....

 

Do suspension and tires and rims first... that's where the real fun comes from. The fact that you can grunt your way from one light to another is meaningless. Just get a K&N filter, cut off the silencer, and maybe an axle back if you want the sound. You'll be amazed how much more fun haveing a good suspension is then a stoopid cia or bov, (which do nothing but hurt your engine).. just my opinion though, do whatever you feel is best.

 

I wonder if the OP has been contemplating the bov, cai for the past two years...lol

 

ride5000 couldn't of said it better about cai's...

 

First thing i bought for my 03 wrx was JDM sti hood scoop, and a TBE.. Love both of them.. next on the list is hid's and then turbo,fuel pump, injectors and bigger intercooler

 

:rotfl: no doubt' I'm sure he's decided already, if he even still has the car.
