Minimum mods to make wrx = sti?

What do you think would be the fewest mods/least expensive way to make a wrx perform equally as well as an sti in acceleration, handling and braking and have good reliability (let's leave out mbcs and other risky items)?

Would a Cobb stage 2.5, STI suspension, Stoptech big brake kit and 17 inch wheels and tires do it?

2.0 can be as fast as STi.

how about

upgrade turbo/boost controller/fuel system/ecu
that should make it as fast

strong brake pads (endless CCR etc..)
makes a huge difference with minimal investment and weight.

good suspention
you can something better than stock STi for about the same price

^agreed. go with a turbo of your choice with the proper accessories and tuning...
if you have the money get a big brake kit and 17s
coilovers and strut bars, anti-lift kit, and whatever else
that should make it an amazing performer...you should be able to keep up with stock stis with that stuff

you might want to get a turbo back exhaust as well, that will give you about 25hp.

What hp does an STi make stock to the wheels? I thought I heard it was like 230. If that's true, a Cobb Stage 2 would get you there power wise. The Stage 2 is a turbo back exhaust with the AccessPort reflash and puts 225 to the ground.

There are many dyno plots, Ive seen stock STi's on different dynos putting down number from 220 - 240 WHP. It all depends on weather, altitude, dyno...etc.

And then just wait for Stage 3 to come out, I'm sure we'll see some more impressive numbers, that will be much better than a Stock STi.

I'm putting in a Stromung 3" dp soon though need to get above 300 crank so my STi sidemarkers stop being r1c3.

Is that safe with the stock turbo back exhaust?

I was wondering if it was safe to have that much power without a TBE. I would think with that much power and the factory TBE you would be increasing back pressure a lot. The only reason I would think this is because Cobb reccomends TBE with stage 2 and thats puting down 224 at the wheels with a TBE (but you do have some mods that Cobb stage 2 doesnt).

It's not cost effective, and you'll never have the low end torque.

Don't forget the 6-speed, DCCD.
