Looking to start working on and putting some money into my car, and I'm fairly new to the turbo scene..I've done quite a bit of reading over the last year or so just haven't really had the money to do anything..well the time has come and so has the cash so it's now or never..and I'm somewhat mechanically inclined that's not the problem..just don't know where to begin really..would be nice to have someone to ask things and to go on a regular basis if I have a problem or to get guidance..so if anyone is willing to lend some knowledge or wants to help I'd be more than grateful..I'm located in Wichita Falls..05 CGM WRX

Thanks
Dylan

The question is: How far down the rabbit hole do you want to go?

Do some reading in the proven power forum so you know what people are doing to their cars, and getting what kind of power out of them.

Then, make a goal and a budget. Say, goal is at least 500whp and 10's in the 1/4, and I want to spend $8000

After that, start researching parts, vendors, tuners, asking questions, and we'll help you out.

It's inefficient and a waste of money if you're modding your car with no goal.

If you want to make a 1/4 drag monster that can do 8's, sure but that'll probably cost you near $20000 just for the engine.

If you want a well balanced car that's a good deal of fun, you can do 380-400ish whp with a medium sized turbo, good tune, stock block, and some money in suspension mods.

A lot of people are just stage 2 (downpipe + access port or tactrix cable reflash) and a custom tune (usually $300-$600) and that will net about 300whp on a pre-2008 STi, 260whp on a 2.0WRX, or 285 or so on a 2.5 WRX. This costs less than $500 if you pick your parts and tuner carefully and provides a great bang for the buck. If you get a full 3 inch downpipe, you can keep that downpipe for future upgrades so it isn't a "waste" and provides a great starting point while you research more mods.

I want to keep it my daily driver but still want it to be reliable and still be an all around good looking/running car, but at the same time make some nice power, it already has a 3" TBE with bellmouth down pipe..I'm not sure about the mid pipe..I believe it's prodrive tho..the muffler is prodrive circle tip..I know that prodrive makes good stuff but I'm not crazy about it..wish it was louder I'm a fan of something that sounds like a monster and runs like it too.

For a DD I would shoot from 300 to 350whp. This is conservative enough if you do not rag on the car it should last on the stock block just fine and the transmission.

You get a 350whp and go dumping the clutch all the time and hard shifting and you might find a transmission issue down the road. Same could be said for a stage 2 car but the more power the more likely it will happen.

Let txic and nasioc be your mentor. Go to a meet and take a ride in different cars with different set ups. Then you can see exactly where you want to end up.

I would go stage 2 for your 1st mods, then work on suspension, new clutch/tmic/fmic, then start going for the big power.

cheap and fun mods are short throw shifters and crank pulleys.

I noticed very little with crank pulley. It wasn't an immediate change that I noticed, it was more of "wow when rev-matching" it was ever so slightly more responsive.

For me, biggest bang-for-buck enjoyment was full shifter bushings (from Turn In Concepts) and downpipe + stage 2.

lightweight pulleys are a gimmick. The engine needs the dampner on the front of the engine, as it helps to remove harmonic vibrations from the crankshaft. A real gain will be lightweight flywheel, although you will lose some driveability. That reciprocating mass helps the engine carry through the cycles while load is applied. Say normal take off from a stop light would now require more clutching to avoid stalling. Tune it. Don't bother with cutting down mass, worry about better use of the engine's management and turbo for now.

Since it's a DD, my advice differs a bit:

-Get a performance alignment, as much negative camber as you can get up front.
-Get good tires, such as Dunlop Star Specs
-Bigger swaybars
-Better brake pads, such as Stoptech Street Performance
-Various driveline/suspension bushings

These mods will make the car much more fun to drive without being enormously expensive. The emphasis, obviously, is on turning and braking, rather than straight line acceleration.

On the power front, since you already have downpipe, get an Accessport or Opensource tune so you don't boost creep and blow your motor.

I was thinking an up pipe( would like to hear all your thoughts on that from manufactures to install..anything you've got) and a accessory and I'd like to change the exhaust out back, maybe blitz I really like the way it sounds..it's just fairly expensive. But I'm thinking that's a good start.

Up-pipe
Accessport
Different axle back

750 double pumper, edlbrock intake, radical cams, some hooker headers and flowmasters

if you want to go all out, put a blower on it

i'd be careful though, WRXs have fragile trannys

To be perfectly honest, just take your old uppipe out and gut it, clean it thoroughly and put it back in. Aftermarket uppipes are expensive for the ones with good fitment, and the cheap ones fit like ass.

So there is no benefit of aftermarket at all? Obviously gutting the stock would be cheaper for sure, would just like to do what is best to maximize power and efficiency

For the money there are a lot better things to do instead of an up pipe. Short throw shifter is one of the cheapest and IMO one of the funnest mods to a car. The kartboy is only about $100 and is really easy to install.

I've read or been told that of you were doing stage 2..an up pipe is necessary..is a short throw something I should do at first?

Sti injectors, 18g turbo grimspeed ported manifolds, mid pipe and up pipe, big top mount, walbro pump and a good tune on a access port
Cost about 3k and make 335whp ish
Just don't dump the clutch
If you have e85 just a walbro pump and bigger injectors and a custom tune

330whp will scare the crap out of most people. I have a 40lb 18g and ran out of turbo at 23psi. I made a little over 330whp and a tad over 300wtq on a stock block and STI 6speed. Next step for me is a fully built 2.5 with a Dom 3.5 and kelford 280s.

Heads are being worked on now and I already have the AEM stand alone. I have a bunch of random misc parts that I found cheap. But when it's all said and done I'm looking at a 6-8k dollar motor. The build starts this spring.

So the question stands how far are you willing to go? You will get bored with 300+awhp in less than a year.

You have more left in that 18g.. It is still efficient up to 25psi and over 40lbs a min...

^^^^ really then tell me why it was surging and stalling on throttle? Because my tuner Jorge said that's it, you ran out of turbo. Once you add an EWG the whole dynamics of that turbo changes.

Might want to re-think that. STi injectors will run out of fuel with a 18G. Heck, your tuner will have to tune around them for a 16G.

OP - Unless you KNOW what you want, your best bet is to talk to your tuner and get your mod recommendations from him. I do suggest running e-85, if it's available in your area.

In my opinion start off with stiffening the suspension/cassis and go to your local SCCA auto cross and have fun. From there you can add power mods that dont comprimise on spool time if you autox. one day youll grow either into or out of autox and that will determine big power vs handling
MY 05 wrx I use for autox but definitly sux(driver) and i have
VF-39
megan headers/up-pipe
helix downpipe
borla muffler
No cat converters
Perrin Crank pulley
Grimmspeed EBCS
AEM Intake
Ebay Big fuggin Top mount intercooler (godSpeed)
Cusco From Strut bar
20mm sti rear sway (imma wagon: stock was 17mm so got this free)
kartboy short shifter
kartboy front and rear shift bushings
turn in concepts 5MT linkage upgrade (OEM was SHOT: but now my shifter has 0 slop)
Ksport Coilovers
and I run the stock 16" with Potenza RE-11 205/35r16 (smaller than stock for autox only) "changes gear ratio so I can actually accelerate in second without worrying about not having any boost. In hawaii our course is so small we barely hit 35 mph so yeah"

I finish last every time because I am in S-Mod because of the damn turbo and everyone else runs slicks and I sux but I have a blast everytime
