Default Advice on what to buy next (2008 wrx)

So I am new to NASIOC but not new to working on cars. I bought my 08 wrx sedan before I deployed and was able to install an AEM cai and I bought an accessport v2 for later on down the road when I put on more parts. I wasn't able to play with it as much as I would have liked but that's just how things go. So, the next steps that I am taking are buying agency power downpipe, catback exhaust and bov. I am also installing a process west tmic and a grimmspeed heat shield for my turbo. The heat shield is mainly for the tmic. I did some research and I know I want the process west but that the heat soak would be extreme from the turbo. ANYWAY, I have some left over cash and would like to put into my subie but I don't exactly know what to get next. I was thinking maybe new clutch and short shifter or some front and back anti sway bars? What would you guys want to do if it was yours? This car is mainly used for street driving but I also use it as my main mode of transportation. Also, I bought a whole new brake system and new tires and rims already so that's covered. Thanks ahead of time.

Oh absolutely a tune I agree. I was looking into uppipes but I read somewhere that the 08 wrx has the same stock uncatted uppipe as the sti. If this is true then I don't see the point of getting a new uppipe. Like I said, I haven't had time to check out my vehicle as much as I would have liked so if you have any info on the uppipe that would be helpful.

That's what I thought. What do you think the next step is BigRob?

Solid point! I would like to be somewhere in the vicinity of 300 hp. I know at stock I am sitting on like 225 or something like that. I don't know what everything I already have will be putting me at already however. Where do you think I will be at with the exhaust and cooling? If you think I will already be close enough then perhaps some drivetrain mods?

On the 08 wrx there is a massive flaw with the suspension. It's far too soft. With spring rates around 140lb/in it's the same as the 2.5i and hardly suited for a sports car.

While the suspension choices aren't as expansive as the older chassis there are still a few good options out there. I highly recommend getting new struts and spring as a pair so you don't end up with a severely under damped setup. The KYB GR2 struts are 15% stiffer than OEM struts and will be able to be matched with almost any standard lowering spring that boasts higher rates. But with these, I wouldn't try and go too far over about 200 lb/in or so. KYB also make the AGX strut with 8/4 way adjustable settings from softer than stock to about 300% if i remember correctly. These will be able to be matched to the more aggressive springs you find. There are also Koni inserts which require you to hack apart your current strut to put in a new strut insert, but they are fully adjustable and you can dial in exactly the dampening you want.
But if you want a complete package then visit RaceCompEngineering. The billisten struts they sell paired with the RCE springs are a fantastic match for a more high performance ride. Non adjustable, but they don't really need it.

That should about cover the basics of upgrading struts and give you a place to start looking. Coilovers are a completely different setup and I'm going to leave that to someone else.

I hope you're not running that intake currently without any tune. If so that left over cash should goto a compression and leak down test. 08+ WRX/STI's CANNOT run any intake without proper tuning.

How much money do you have, and what is your budget? We can throw out X, Y, Z parts all day but it doesn't mean crap if we don't know what you want to do with car.

I have about 1000 left to spend and be comfortable with it. Yes I already had it tuned with the cai. That's the reason I bought it along with an accessport. With everything already I have about 4500 into it and another grand wont hurt. Just kinda wondering what you guys would do with that extra grand I suppose.

Okay, you have 1K to spend but didn't tell us your goal for the car.

Buy fuzz dice and an 8 armed elephant to put on the dash.

He did Well...kinda.
You'll need a full turboback system
An ebcs or external wastegate to control boost
FOR SURE an upgraded intercooler which you already said you're going to get?
And one hell of a good tuner lol
An AOS (air/oil seperator) isn't a bad idea either
BUT for $1k you can probably only get the downpipe and the ebcs because the PW TMIC is almost 1k alone and a protune is around 4-500
If I were you, with that budget, I would get a catted downpipe, a nice used exhaust, and a Torqued Performance stage 2 tune...you'll be around 270hp MAYBE...you might need that EBCS to control boost

Well I did say earlier on that I wanted 300 hp at least. So theres that. Also, the original question wasnt what I wanted to do. I was asking your opinions since you have probably already had mods installed on your vehicle and gone through this same dilemma. I wanted to know what you would do with that extra grand is all.

All the stuff above has already been purchased or has already been put into the budget and then I have 1K left over. Sorry, should have been more clear on that! So I already have the catted downpipe and tmic ready to go. You think turboback would be a good idea? I was thinking about ebcs too. Got any you would recommend?

while you dont need bigger injectors for stage 2, i was at 100 duty cycle with just a downpipe and intake. full turboback, intake, 3 port, inj, fuel pump, and since you have an 08 get the vf52 off the 09+ wrx. get protuned, you will be over 300whp

I would highly recommend suspension components, such as new springs, sway bars, end links, bushings. Really as much as you can cover with that $1,000.

I guess for me I would need to know if there is something specific you dislike about the car now? I know when I bought me STi I put on a set of Toyo 888's and quickly HATED the 50,000+ mile stock suspension with how nice the tires gripped. I will always say to make a car handle before you worry about power.

I was waiting for some one to mention the VF52 as for numbers that depends on the dyno some read really low some read really high regardless of the make. all depends on how that dyno is calibrated but with a VF52 and the mods Rob mentioned and a good tune he should be near his goal. with the TD04 aint gonna happen
