Default Looking for turbo setup for my WRX that can eventually be put on an STI. Need help!

I am looking to make the initial investment now and put the parts on my WRX and run the set up in moderation (250-350whp on stock block and tranny).

Then eventually buy an STI in a few years when I can find a used one for a decent price (also my insurance premiums drop) and start making serious power.

Here is a list of what I plan to buy so far.

UTEC
FPGreen or GT30/35R (can't decide)
Turbo back exhaust
850cc or STI injectors?
Walbro 342 Fuel Pump?
WORX BOV

PS: To what hp/tq are the stock intercooler and intake goof for?

if you are planning on buying the STI, you would be an idiot to invest any of that money into your WRX. Use it to pay the loan down.
That said, you can do a few things that will bolt up to the STI, just keep your stock parts.

You will not be able to run the WRX utec in teh STI, so thats a waste
The STI has a big enough fuel pump, so thats a waste
The injectors will not work with the STI, so thats a waste.
The BOV is a complete waste on EITHER car as its a non power mod.

There are several things that will make your WRX MUCH more fun to drive and bolt up though.
Tanabe GF210 springs (04 spec)-- Will make the STI lower, ride BETTER, and handle better
Turboback Exh--Bolts up to both cars, will make your wrx faster, will make the sti MUCH faster
-- Short ram intake, will do NOTHING for your WRX, will make a good 10whp on an STI


If you are dead set on buying your turbo now, you will be re-selling the pump/injectors/ngine management when it comes time for the STI. Also, remember that any turbo that wil be a worthy upgrade on an STI will be VERY laggy on a 2.0

Best bang for the buck for injectors for your WRX would be modifying your stock injectors, its FREE, but you will have to replace them, so maybe find a set of them used. You will also need some serious tuning to get them running right, as no one has off the shelf maps for them at this time.

You need to also really figure out what you want. You say 250-350whp on stock block and tranny, run in moderation.
350whp is NOTHING NEAR moderation, and at that power level, your stock block and tranny will not last very long. There is a WORLD of difference and a couple thousand dollars between 250whp (full exh, tmic/reflash) and 350whp (a vf22 on 114 race gas)
at 350whp, you will be driving a car capable of a 12.0-12.1 and will CRUSH 99% of the cars on the road. Why even bother with the STI at that point? You will have long since shredded your tranny anyway, so you will already be into an STI tranny or dogbox.

Your best bet money wise is to ditch the WRX ASAP. Yes, you are probably upside down in the loan now, but that situation will only get worse for the next 3-4 years. Yes STI prices will drop used, but so will the trade in value of your car. A 2002 with 45k is already only worth 13k.....

BTW stock intake is good for 400+whp. ALthough I picked up a good 7whp with my short ram once tuned for it (VF22)
Stock TMIC is good for probably 280 or so, anything over that and you are going to want something better. The tube and fin design of the stocker is really restrictive. Go bar/plate

Thanks! This is an excellent explanation, I am going to check my insurance on the STI. I think you are defintiely right, the more I think about it, the 5K$ differece between a used WRX and STi is soooo worth it (wheels,body kit, suspension, 6spd mt, fuel pump, injectors, 2.5L and the list goes on). Look for my car to be for sale on the forums ! Thanks again!

I mean I am keeping my wrx simply because it will cost me less to upgrade the drivetrain in my car than it would to jump to the STI, and the tranny is the only thing left inferior to the STI at this point (other than the steering rack, which is cheap enough....)

I also already have like 10k invested into mods in this car. Something I never would have done had I known the STI was coming. If you want an STI, BUY AN STI, unless you already have bank into your current car...

When I was pricing a WRX and STi, I was quoted a cheaper price for the STi. When I asked why the said it because of having more safety features.

Just FWIW
