^^^ Why people buy a used wrx/sti is still dumbfounding.

If I were within the 5 days, I'd dump it and get a new one.

EdWRX, what did you finally do?

HAHAAH "illuminati Confimed" Upon modifying my car and also trying different oils I read into the threads and had trouble deciding whether or not to modify the car. 10 months later I'm protuned at stage two plus cobb .

etune or dyno tune, it shouldn't matter so long as your tuner knows what they are doing. Unfortunately, too many "tuners" seem to be popping up and people are trusting them with their cars, for some reason.

Do your research, only rely on reputable tuners with proven results and you should be fine, either way.

There are thousands of people who buy used WRX/STIs without issue. There are occasions where buying a used one makes sense and can be perfectly reliable.

I bought a used '07 WRX Limited with 50k miles on it a while back and drove it for another 70k miles with no issues. 40k of those miles were driven with an 18G and supporting mods and it performed flawlessly for me the entire time I owned it.

Additionally, my Dad wanted a 2016 WRX and was looking to pick up a new one. But after stumbling across an immaculate 2016 WRX Limited with only 6500 miles, for only $26k, he pulled the trigger on it and it has been perfect for him. Granted it was bought new by a 60 year old guy who initially paid cash for it and realized he wanted another corvette instead. So my Dad got essentially a new Limited for a smoking deal.

Long story long, used WRX/STI's do exist that are worth buying. Just do your homework. I almost always recommend paying a little extra to have a compression test done if you plan to buy a used one though.

Default Fuel pump question

I've been lurking on this thread for awhile. About to go stage two mods plus Gs EBCS, charge pipe and tgv deletes. Never though about the fuel pump concerns.....which brings me to my question - does this upgraded fuel pump require a tune?? Or can I install it no mater what and the ECU will know how to use it? Thanks guys!

Ask your tuner if he recommends an aftermarket pump. Many prefer the the stock pump. My tuner does and my stock pump works fine at stage 2 w/stock turbo on e85. OEM pump is more reliable than the aftermarkets.

Yeah I really don't think a fuel pump is needed especially on pump gas.

Ok thanks so much for the response. I'm currently planning to go to IAG tuning in Maryland in the next couple of weeks. Excited but nervous!

I would say my driving style is fairly normal, nothing too crazy. Every once in a while some spirited pulls. Just used it as a daily driver, no track/autocross time.

Can't really figure out what caused the failure... the master mechanic at the dealership I get serviced at could not find the root cause when disassembling the block either.

He's not a master mechanic if he can't perform a proper autopsy. There is always a reason for a failure and always evidence of the cause.

The concern I'd have, is without the understanding of what caused the failure, it may set you up for a scenario where it will just happen again.

Higher gear low rpm full throttle applications? Like flooring the throttle on the expressway in 6th gear.

hate to call you a noob, but it doesnt exactly take much to get a "master mechanic" label at a dealer.

How many miles did you have on the oil change when the bearing spun?

There were a few instances where I had to use 50% throttle low rpm in 6th, I don't think it was too severe though.

I totally forgot to update my failure post. Can you update your OP, edit mine to read "spun main bearing"

For those late to the party, my build thread is here

I have the dubious honor of posting twice in this thread!

Model/Year: 2015 WRX base
Milage: 21,447 (~3.5k on new IAG stage 3 block)
Mods: See: http://forums.nasioc.com/forums/show....php?t=2790176
Fuel: 91
Oil: Driven DT-40 5w40
Circumstances: Ever since car was back together after the new build, I would always have random rough idles, and/or p0300. I had also had p000a which was solved by replacing the oil solenoids. Anyway I was e-tuning back and forth with my etuner after block break in, until one day doing a slightly hard drive in 3rd through 4th entering freeway onramp in 106F weather, significant engine power loss was felt (Accompanied by knock on the AP), black smoke out the rear, and engine died while I was coasting to the side of the freeway. Upon inspection of engine bay, oil dip stick shot out and oil sprayed out from there. Car now turns over but does not start (and turns over rather slowly).

Ooof. Sorry to hear that brotha. Hopefully it's nothing major, but that doesn't sound good.

...that's some terrible luck. Also 91 is a nightmare. I moved from the west coast to Alabama and the 87 here registers less knock than the ACN 91. Hope it's not as bad as you're thinking.
