are you in that car club that hangs out at the lot in sunbury? the one with the white civic with lambo doors? you probably know who i am. i have the red wrx that had the carbon fiber on the roof and pillars. its repainted now but ive heard theres been some "talk" about my car from that car club.

[Steveo47193]

Hey man ya I'm in that car club. I don't recall anything bad said about your car and if there was it wasn't from me that's for sure lol. But let me know if you wanna get together and talk about your car. Let me know either way.

Good ol fashioned Scooby camaraderie . Gotta love it.

lol i need a subaru guru. ive had my car for 3 years and still have yet to find someone who knows the problem. i almost hate driving my car because everytime i hit 3k rpm it cuts out, makes weird coughing noises, my boost drops then it takes off and is fine. it seems like a boost leak since my boost drops for a second when the "coughing" noise occurs. but it only does it at around 3k rpm.

Got anymore detail about the problem? What kind of mods do you have done? Is it tuned?

Ok...I looked up your mods...what kind of turbo is that?

[KandyWRX02]

i dont know much about the turbo. it was on the car when i got it. i know its a momentum ej05 40t. i think its pretty much identical to the 18g? someone correct me if im wrong on that.

[Steveo47193]

wow 3 years and still no answers. That sucks man. i have no clue what it could be. Did you take it anywhere like a garage or anything. I would take it down to Precision Tuning. They are down in New Jersey though i believe.

[KandyWRX02]

i already had it tuned. i dont really wanna spend another 500 bucks if i can fix the problem myself.

[Steveo47193]

I'm not saying to get it tuned I meant to find a solution to your problem.

[KandyWRX02]

id rather if someone told me what it was so i can fix it myself. i dont have the extra money right now to take it to someone else to get fixed. i think its something with my turbo or wastegate.

I don't know how much help this will be, but hopefully it will give you a little more of a lead on the problem....since I own a mazdaspeed protege & not a subie I can only provide my own similar experience...here goes:

My MSP stock set up is a GT25 turbo running ~7psi of boost...air is metered via a Mass Air Flow (MAF) sensor in-line with the intake tract. I have the car currently tuned to ~10psi , which is the rough limit that the car can handle before exhibiting the same behavior you describe (car chokes/engine bucks...then takes off like a rocket), along with a Cold Air Intake. On colder mornings (winter time, etc) this happens very often, and in the warmer weather I don't get this to happen very much at all. Basically, the temp sensor coupled with the MAF is the culprit...when it sees the colder (denser) air cooling the sensor in the MAF, it assumes there is too much air (it sees this as exceeding the stock 10psi threshold)...in warmer temps the air drawn through my intake is not cold/dense enough to be read as exceeding this point, so hence why I do not get the same symptoms. The car will only behave this way if I go heavy on the throttle and push my boost up near the 10psi point...I've since learned in cold temps to moderate my foot while still being able to elicit about 7-8psi...but mostly I just avoid hard driving in the cold until I can get under the hood to perform the proper fixes

Does your car behave in this manner?...does it only do it under hard throttling (aka in boost) vs. mild acceleration?
