Buying 04 wrx sti....mod. advice please

Hi all,

I'm about to buy an 04 sti. It's coming from Germany as i live in Tenerife. It's still standard 265 bhp, but i'm tempted to improve it. If i chip it to 300+, is there any recommendations or things to look out for. Also the dump valve thing that makes it sound good in between gears... does this improve performance?? Again, anything to look out for?? Any other easy things to improve performance?

Is the pro-drive pack a form of chipping?? Excuse my ignorance but i'd appreciate any feedback.

Thanks

Craig

p.s. it's lovely and warm here :-)

Hi Craig

No mate you get a New ECU.

STi PPP includes a round tip rear muffler, and exhaust mid-pip, a free flow catalytic converter / down-pipe, a cat-less up-pipe, a silicone intercooler Y-pipe and ECU upgrade. You get approximately 60 HP over the standard car.

Does it actually improve power, performance or economy ?

Or does it just make a nice psssstt noise ?


There is a lot of debate on Forums regarding Dump Valves. I have the HKS SSQV as above and car runs fine and sounds good (IMO).

On some cars a VTA (vent to atmosphere) DV can upset the car. Mine has PPP and is running fine with a VTA DV.

It's a personnal thing, no increase in BHP but can improve spool up time (so some say)
