Simple performance mods?
Wasn't really looking to modify the engine at all on my car but it just doesn't seem to have the performance like my old seat leon did.
It was only a 1.8 20v turbo but was pushing out just shy of 250bhp with a 6 speed box
I now have a 2005 WRX SL with the PPP pack on, but the car doesn't really do it for me at the moment, I have been reading that the exhaust system really restrict these is that right?
Any opinion or pointers to get it to give a bit of better performance would be hugely appreciated

Look on here for quality second hand parts and it wont brake the bank neither.

Hi there
Speak with Neil@Slowboy Racing,he's located just near Brands Hatch and I would suggest speak with him about the mapping yours car
With what mods I would go,probably as first decatted downpipe(2.5") and decatted centre pipe(2.5"),fuel pump upgrade(HRC 255LPH) and better panel filter(K&N or Green Cotton),decatted Up pipe(STI Up pipe cost around £40-£50)
With those simple mods you should be able to make somewhere from 270-300bhp,depends on few factors,but usually 270-280bhp is quite normal
More expensive will be if you want to go above 300bhp,due this i would speak first with Neil about the next steps

I suggest you go for a few handling mods and a geo set up, get some negative camber to help it go where you point it, and you'll find it's a much quicker car than the power would suggest, you might also want to look at the brakes too.
Imo you shouldn't really need much more power once set up properly the speed you can carry into the bends and out of them will be the main factor in making the car quicker, in my experience once you get into 3rd on a country road it's all about the handling and the brakes, more power won't necessarily make you faster.

Am I able to get negative camber without adding coilovers and camber kits? Like is the car currently adjustable as standard or am I going to need a kit to do this?
Also how does the geo setup work? Is this kind of like the tracking etc?

It's got a prodrive rear box is this ok or would you recommend changing this?
And is an STI up pipe a direct swap for my original? As I was told the prodrive have a different up pipe to a standard WRX?

Hi there
Yes you can have more camber without the going with coilovers and camber kits,on Subaru you can use camber bolts,which cost £25
Like now you should be able to have negative camber at -1.3',which is in most cases enough,but main difference you will find when someone will set yours suspension right
Yes is something like tracking,as I said speak with Neil@Slowboy racing,he setup our suspension and we are very happy with his work
Neil@Slowboy racing now doing full wheel alignment and its worth the money have suspension set
Jura
Any particular reason as to why go for the 2.5" setp and not the 3"?

2.5" is not restrictive up to 350-400bhp,what can be restrictive above 350bhp can be the backbox(if you are running Prodrive),the I would have look on still awesome TSL Group N backbox,have run this and still we are prefer this backbox awesome noise and not loud,slightly louder than Prodrive backbox
About the Up pipe,STI Up pipe is decatted and WRX is usually catted(have cat inside),only 2.5L WRX don't have catted Up pipe

Jura is defo talking sense with handling advise, if you get more power from it you will soon realise that the brakes arent up to much either, once you prepare your car this way you could go down the route of sc38 or sc40, pink injectors a 255 pump and a map and your car will be a ****ing weapon on the road there wont be a lot out there that could compete

You can have your alignment sorted for as little as £40, all you need to know are some settings, google is your friend.
Since I had mine done recently it's made a world of difference to the way she handles, mine has some stiffer springs and I run 18's too, added to my AP 4pots up front and it makes for a pretty quick daily driver, and that's only with the PPP, for me it's all about driving style, which needs to be adjusted for every type of subaru, but make no mistake it will take something running some pretty serious power to leave one of these cars in it's wake when set up and driven properly.
I still have more to do as it's still lacking when pushed hard but I know what needs to be done to make it a serious point to point tool and it doesn't involve power increases.

Evening all, I've now had my car for just over a week and I think something is wrong
Previously I had a seat Leon Cupra 1.8 20v turbo(180bhp) I fitted a front mount, forge turbo intake pipe, forge recirc valve, 3" downpipe decat and a 2.5" cat back cobra sport system and a remap to which it was running just shy of 250bhp and 267ft/lb k03s turbo at 1.3bar
As you know I have a 2005 impreza wrx ppp so roughly 260bhp I believe? But my Leon was far quicker or at least it felt it. And also the impreza seems to use a lot of fuel even sensible daily driving. Is this usual as I know they do like a bit of fuel anyway
On the plus what could I do for a bit of extra power as it seems so sluggish, it's like sometimes if I accelerate in first you don't feel the turbo kick in, other times you can feel it when you have the revs kept up so the boost is up there still
Recommendations please guys.

Hi there
New age(01-07) is heavier than yours Leon Cupra
I would recommend get yours car mapped,with extra remap you can extra bhp,but still I would rather go with the slightly bigger turbo like VF28,VF34,pink injectors and then you should have nice 320-350bhp
Really depends how far you want to go

Thanks for the reply. Would that power be ok on standard internals?
At the moment it's standard apart from the prodrivr backbox etc
I was thinking of going for a nap speed header, decat uppipe and a 3" turbo back exhaust system would this free the car up better and be a bit more responsive?
Also would the above bolt together with a vf34 and pink injectors?

Also what would the spool time be like as the car seems pretty laggy as my Leon had a smaller turbo so a bit of throttle and it was pretty much there
What are the vf35 like too as I found one of them

Hi there
You don't need to buy new headers,you will loose spool with aftermarket headers,rather I would have look on ported OE headers or possibly STI headers
Decat Up pipe as above speak with Alyn@AS Performance or try source STI Up pipe,those two are better choice
3" exhaust you don't need,arther I would go with 2.5" decat downpipe and centre pipe,with 3" at the 350bhp you will loose torque and can loose bhp,3" is good if you are thinking go above 350bhp
Yes pink injectors and VF34 or V28/V35 or any other TD05-16G will be straight bolt on
WRX internals,this depends,we run for few months without the issue 350bhp,some people run on their WRX 400bhp without the issue,really depends on few factors
I would suggest speak with Neil@Slowboy racing and get car check for DET,AFR and compression and then you ill know for sure if its OK to run this power

VF34 is better,but more expensive choice
If you will put something like 20G on yours WRX then you can feel lag,but with those above mentioned turbo you should be OK

All Impreza's are crap on fuel, get used to it, or get rid of it.

After reading around I think I will be going for a VF34, planned mods are
VF34
Pink injectors
Decatted uppipe
Turbo back exhaust system, all cats removed or I may have a sports cat downpipe
Was thinking of going for an STI intercooler, what are your thoughts on this?
What is the best air filter application to go for? Would you recommend any particular dump valve or is the standard ok and is the standard turbo inlet hose ok or would you recommend upgrading this.

If you want to keep Prodrive backbox then you will need to buy downpipe and centre pipe,if you don't want to keep Prodrive,then you have lots of choices in the exhaust department
STI TMIC,depends how far you want to go as I said previously,if you want keep around 320-330bhp then I would keep WRX TMIC
Best air filter,I would go with K&N or Green Cotton Panel Air filter,standard dump valve is OK and will be OK for yours needs
Inlet hose,depends if yours existing is in good shape,if not then replace with the aftermarket like is Samco or Viper
Cheap inlet hose will or can shut under heavy boost

I'm going to try and source an STI up pipe and then I shall take a look at exhaust systems... I see a few Japspeed ones that seem ok but I been told they are not very good do you know if that is true?
I think I'm going to go for a Samco coolant and boost hose kit so I think I shall get the Samco inlet hose too, for filters is the k&n typhoon kit ok? Or do you mean the panel filter
Would I be ok to fit the VF34 on my car if I keep it out of boost, to get it to where I'm going to map it or would I need to disconnect the actuator hose or something untill it is mapped

Mate, you need to get used to the Anti-Anything-Other-Than-H&S-Miltek-Etc-Etc brigade on here.
Theres nothing wrong with the Japspeed exhaust. Mine is running good power as above and my mate runs 400bhp+ on his. An exhaust is exactly that, a bit of pipe to carry gasses out the back of the car. If its good grade stainless steel and has decent welds it'll do the job
Standard air box is good up to near 400bhp, so get a panel filter as Jura advised above.
Car will run fine off boost to get you to the mapper. The ECU will run closed loop on light throttle so fueling etc should be ok even with the bigger injectors.

Is the Japspeed what you run?
With a full exhaust system would I see any improvements? If I got a Japspeed up pipe and full turbo back system using either decat or sports cat first pipe
