I just flashed my car to Stage 2 today and I just need to use this thread to say WOWOWOWOWOWOWOWWOWWO!!!!!! My car is a f%^kin beast now....sorry if this is weird for some of you people who have been stage 2 for a while, but I am just totally surprised and did not expect my car to have that high of a performance increase.

 

i'm planning on doing the same. right now i'm running perrin up/downpipes and a hks hi-power with NO engine management. what kind of difference in horsepower and torque do you notice? what year is your car? i've got an 05. thanks

 

My car is a 2004 WRX and got the full turbo-back and up-pipe. I am not sure about the hp gains, it feels like a good 15-20 to the wheels. All I know is that it made a pretty significant difference in the power band; its just so much smoother and when the boost hits, it hits really hard. You'll get thrown back in your seat every time you shift.

 

lol....nice man, congrats....i just purchased an 05 wrx last week.....its out of state and im waiting for it to be shipped over.......in my impatience i also bought a cobb ap.....the car has hks hipermax already on it (its used) and im planning on lowering it and throwing on up/dp and cobb stage 2 the first week i get it.....

 

15-20 to the wheels is insane. my head is looking forward to hitting the headrest again. thanks guys

 

well, i wouldnt call 15-20 to the wheels insane, lol, but its a very impressive gain for the money

 

stage 2 will only last for so long...you'll get used to the pull quick...but it probably is one of the "best bang for the buck" mods. I actually did pretty good with stage 2...13.64@98 (03 wrx)...now got a VF in and it feels soooooooo much better than stage 2 (but then again, i also did an RA gearswap)...only thing is, our track closed down before i could run the 1/4...hope you enjoy the setup

 

13.6@98 with stage 2?!! wow....thats very good. so did you have all cobb parts or mixed and matched?

 

is it possible to run stage 2 with only dp/exhaust? sorry for the noob question

 

^^^correct me if im wrong, but isnt that stage 1?

 

stage 1 is simply engine management with no exhaust modifications (though catless uppipe alone qualifies as stage 1 also). you can run stage 2 with just a downpipe, but will get maximum benefits when running an uppipe and a full turboback.

 

so no uppipe will dramatically affect the power increase of stage 2 or is the uppipe more for quicker spool?

 

at that time, my mods were:

pde uppipe
bosal divorced downpipe
gutted 3rd cat
HKS Carbon-Ti Catback
HKS bov
Zerosport I/C Shroud

....not too bad...also considering it was at Hawaii Raceway Park with high high humidity

 

thats very nice...

 

with turboback and intake, I got 190awhp and 180tq in my 04. after UTEC... 219 for each. definitely the best decision ive made for my car. its a HUGE difference in terms of the feel of the car.
