Default 300 whp, how reliable on a stock usdm 2.0 wrx motor

I would love to get close to this amount of power on my 03' wrx. I have heard that the stock usdm wrx 2.0 motor at 300awhp is'nt reliable and will blow at anytime. Is this true? Can all you fellows with this amount of power give me some input and what setups you guys are running. Any input is greatly apreciated. THANKS!

You can run 1000 WHP with a good tune as it's 99% in the tune. That being said, with a good tune, 300WHP is around the max that most people will say that will last for a decent amount of time on a WRX. As to setups, there are about 97,000 different set-ups that will get you there and this is NOT the place to list them all. RESEARCH as Johnny in Pittsburgh's set-up will NOT make you happy. It's YOUR CAR, so you need to find out your goals through the powerband, your car's useage, and figure out what best suits YOU.

if 300whp wasn't reliable, then my engine should've went 27k miles ago which was back in June 2005

I've been on my setup for just over one year now about 12k , the key is like Unabomber said is the tune, and I always run a extra gal of 100 octane just to be safe esp with 20psi.

i've been at over 300whp for 50K miles... No issues... but then, i tend to run more efficient turbos than most to get the power, which i think helps with longevity....efficiency, tune, gas, mechanical empathy... all go toward making it last...

i ran 324 awhp and 303 awtq on 2.0l and stock clutch and 5speed for about 12,000 miles.it is all in the tune!!!!! then the dealer left my oil filter loose after a oil change which costed me my engine just a note my stock clutch looked almost new after 45,000 miles of use. dynoed about 6 times and several runs at the strip. now i am on a forged sti motor with stg2 cams and about 8000 in turbo and other mods .with my stock 5 speed,and act clutch don't think it will be lasting long now

they used an oil filter that they recalled for coming loose. they fought it for a little while ,but several independant adjusters all came up with the same conclusion . oil filter came loose. then they tried to say it was because my car was heavily modded. they then hired thier own adjuster,and he said it was the filter the part# had been recalled so it was the dealers fualt 100 percent for using a defective oil filter. i win they loose. the service manager jay something or other from gary lang is in for an a$$ kicking when i see him on the street. i know he will get this message to

Everyone complains the managers don't want to do warranty work, which I just don't understand. They get paid by SOA for warranty work so what is the advantage to denying claims? Someone please explain.

I've had 315 whp for 35k miles now, with about 75 passes at the strip. I had 264 whp and 150 passes from 8k miles to 40k.

this goes beyond trying to turn down warranty claims. i was told they will not touch my car for anything,and i should go to jiffy lube for oil changes . this manager will be fired when i am done. the dealership owner loves me and what i have done for them in the past( selling several cars for them) i will not be happy until this guy is out of a job and has to move into a refridgerator box.

Let me just say, there is 300whp... and then there IS 300 whp. Some really do have 300whp and some just think they do. If I had a nickel for every 260whp car claiming 300whp....., Oh I know you have dyno plots to prove it...... I have one showing 500 ft TQ at 2000 rpm.

Some motors go sooner some later, Bottom line, start changing turbos and stuff then plan of a 25K mile motor. If it lasts longer, great. If it does go, then then you won't be suprised since you expect it to.

If your plan is to make a metric ass load of power and cross your fingers on reliability, and if it goes, then be out alot of money and not have money to fix it and the try to blame everyon else, then I suggest not modding.

Once you mod, you carry your own warranty. Expect failure. "Hoping" it lasts is a horrible plan. In fact, I submit, it is no plan.

Good luck!

That is a downer if I ever heard one. First off, I completely understand where you are coming from. You are giving people the brutal truth about modding. However, if everyone expected failure A-no one would do it and B-there are way too many cars (Stage 2 and more) that are running fine. Much depends on tune + driver.

I "hope" this isn't true for an incremental turbo upgrade, say a vf-34, with a conservative tune. I'm thinking seriously about doing that, but I wouldn't if I thought it would destroy the engine in a year and a half.

i am thinking about going with the cobb stage 2, they claim 285hp or even a VF34 setup which claims 320hp.. but what about the tranny? my car has 70K miles on it.. i heard the previous owner used synthetic gear oil, and i know i use redline, but even at that rate, how long can you expect the tranny to last if you autocross, rallycross and run it at the strip?

personally, if you want reliable 300whp, then get a turbo that can easily make more, and tune conservatively. I make 320 on pump, and that is conservative to a degree, but i could be much more conservative.

The cold hard truth is what many have been saying in this thread, you have to pay to play, and if you want to make almost double stock power, you're going to have to realize that there is a chance things will break.

If i were you, i would buy a vf28 (small turbo), a tmic and some pinks, do a ncie tune to it. Turbo spool is about stock, it makes more power, and is great for daily driving and some weekend fun. A buddy of mine on these boards has 100k+ on his 02 with this setup (stock IC actually) and it's still going strong. (this won't be 300whp even on a dynapack)

well then what about 300WHP... how long will your tranny last against that much power? i have heard of people having serious tranny problems with everything stock and was just trying to gauge how much that tranny can take... i guess i'll just post in the tranny forum, sorry
