How long can you expect the modded 2.5k to last?
I realize this will depend on many things. I just see a lot of people run a large turbo such as a 30r or 35r on the stock block and internals with the Sti. What about miles? Does this matter?
My problem is that I have a 03wrx with a 20g setup that spun a bearing. I also have a 04 Sti that is completly stock. Ron from axis said that he would take my 03wrx in as payment on a complete engine rebuild and turbo setup for the sti!! Around a 500whp setup for no cost except my broken wrx. I got a good deal on the Sti because I knew I would be building the engine and bought one with a lot of miles. But now that all of this has happend I have considered skipping the engine build, bolting on a 35r kit with supporting mods, and keep both cars. Sell all the stock sti and aftermarket wrx parts, fix the wrx, and make it a track only car. Its a hard choice. One crazy fast Sti with a motor I can count on.....or two cars, one that needs fixed, and one that is fast but could possible break at any time due to the high miles. What do you guys think? Will the stock sti block and internals hold up to that kind of abuse even with that kind of miles?

Im new to subarus but not to running off stock internals. First why do you need that kind of power?
I personally would go with the STi due to its drivetrain and strong tranny, much stronger than the wrx's. unless you have a 2jz or 1jz or an rb25-26 dont run 500whp with expectancy to last on stock internals.... honestly what made you think it will last? Those guys who go all stock do it just to see how long it will last. expect only a few thousand miles at the most. and with the wrx, you will need a new tranny, new clutch flywheel, brakes, tires, exhaust, tune.... even with the sti you will need quite a bit of new stuff. If your serious about that kind of power, you should be talking this over with a good tuning shop. Honestly this is at the level of hp where you need to do forged internals. I suggest keeping the wrx after fixing it all the way to a 250hp dd, nice cool fun. then if you want to do your sti with huge amounts of hp go ahead. i would consider new internals for anything above 400chp. besides when you are going to yank out the engine for injectors ect, why not spend another 2k to get a reliable engine? its insurance my man... spend 2k or blow ur engine later on... 500awhp on stock internals is on borrowed time. |

My stock engine (STI) made it 40,000 plus running between 400 to 470whp... (depending on the map)
I am surprised it lasted that long....... |

another problem with buying a used car for aftermarket is you have no idea what the engine has seen (oil starved, 87octane fuel instead of 91, seen hard driving, been boosted) you might be able to get away with it for a dd and not running it hard, but for a racecar... yah that is almost exactly what aftermarket internals are ideal for. You dont have to listen to me, but personally i would change out internals... or you could focus on making a super light car with 375whp... that might be more reliable... and maybe cheaper? |

not at all. maybe mine was not so great from the factory. i also think im a lot harder on my motor than most. it hits max boost and redline many times per day.

yeah that makes a difference... and if your making a car for raceing... well duh your gonna be going full speed all the time its running... hence the need for a strong engine... i dont understand how you could expect high miles for that much horsepower... this really isnt a super strong stock engine.... its pretty damn good but its no rb or jz.

You ask why I want that much power??? Ahh because I have worked my way up to that point and its the next step. Ron from Axis is one of the best out there and he does my builds and tunes. Do some searches newbie!! Now....please, from some of you specialist out there with SUBARU knowledge, should I go ahead and get the motor built in my Sti as apossed to keeping the wrx? Or should I keep the Wrx and just hope my Sti motor doesnt pop? |

I would say between 40 and 50% of the time, I beat on it... (Limiter set to 8K, probably saw 6k every day... ) A lot of making it last is just what you said, taking care of it... The other part is the tune.... I agree with you that it is best to replace the internals... 500 whp on a stock block is just asking for trouble... I consider myself lucky that mine lasted as long as it did... I haven't torn it down yet, but it now has two oil pumps... One for the oiling system, and one that now pumps it out everywhere else... I would assume the ring lands gave up on one of the cylinders... I don't expect my next engine to stay together much longer that that either... It will be fully built, and torn down as soon as it shows any signs that it needs gone thru... Expecting a 500 whp 4 cylinder to last is just unrealistic in my opinion... It is going to wear out... It all comes down to the old saying... If you're gonna play, you're gonna pay.... |

The question you asked is definantly one of those: "What do you think, even though ill still end up doing it my way" kinds of things. I gave you my opinion. If you think that I should know your whole subaru mod history before I post you are an arrogant fool. Seeing that you already have all that good stuff in your WRX would make me lean to saying trading it for a turbo would be a rip off. You dont have to listen to me but you could be a bit more courtasy of somone who has made some high hp cars. Lets list the facts: WRX bad engine, good tranny other good mods. Could keep that or trade it for only a turbo on an STi. Lets look at the value of the turbo and the car. I would say the car has more value sentimentally and physically. maybe part out ur wrx and use the money to pay for the turbo. If you are such an expert in subies (im not trying to be an ass here) you should easily be able to make a custom turbo kit yourself. I and my friend did for a 240sx with rb26det and we really didnt know what the **** we were doing. Then have aron tune it. thats what i would do probably. |

Decide what you care about more a turbo or your broke wrx.... then do what you feel is right. Only if YOU personally decide what to do will you feel ok. maybe part out ur wrx and use the money to pay for the turbo.

I am only asking through this whore'd thread......@ what whp does the stock internal 2.5l USDM sti block become nimble and need internals replaced. Do some searches and see how many guys on these motors are getting unbeliveable WHP all stock and holding up. Im not leaning toward that choice......just looking at the facts...its been done many times. Just like guys running 11's on stock Sti turbos. WELCOME TO SUBARU!!! |

ill just throw another question in the mix.. how long do u think a built 2.5 (sleeves, pistons, rods etc) to last at similar power levels 500 whp.
I know in aus that ppl are getting problems with more than 18 psi and 220 kw atw with things going pop (i.e cylinder walls ovailing and pistons smashing).. |

sory bout double post but heres a viable solution:
Go to the classifieds and post up all the bits and pieces you can think of. Say that you are considering selling the parts. Have pple email you with prices. Tally up the prices. Find out how much the block ect everything you need will cost for the build up. Then find a reputable shop to assemble it and get a quote. Finally find out wether you can get even with makeing it your self or having a shop ect put it together. That way you can help the community as well. i really dont know the condition of your wrx so i couldnt say for sure but im betting you can get some decent cash by parting the car out. my buddy parted out a civic for money for a rebuild on another civic, and actually made a few thousand... which he probably spent on gas lol. |

^ My engine in the hands of Ron is not in any kind of danger. That I promise you. Ounce the build is done, 500whp will not have any problem wear and 650whp is very reachable. Internals are nothing more than a insurance policy.

drew if you blow your engine... dont blame it on anyone except yourself and Ron. insurance? ok if thats what you want to call it, but no matter the circumstances after enough hard driving i garentee you that your engine will blow. Unless you use your car as a dyno whore dont expect it to last oem life span or even a 1/4 of it. Sorry dont mean to be rude just honest. Hook me up with a block when you do waste it! lol... as long as its free or just price of shiping i will take it.

^wow, you must not have a very strong setup and this is like one of those " My car is slow and I wish I could get it built, but since I cant afford it and dont know anyone who can build and tune, il bitch about it on others threads"
Please stay off this thread 0-60! You have no knowledge of the product and you can not compare apples to oranges as far as engines go. DSM's I have built, subaru's I have built, and yes I have messed with a lexus and did the Supra swap like eveyone else. Totatly differnt worlds. A fully built 2.5 with 450whp is = to having a factory block with factory whp as far as wear and tear go. Simple as that.......mine is a daily driven car that races on a slim basis to boot. And if you say anything else please make sure to read carefull to avoid making yourself look like an idiot again. Thanks! |

Personally, I would have Ron fix the 03 WRX....make it your track car as you say. Then leave the STI as your daily driver.
As much as you think having a built motor means everything is good in the world and you will have no problems, that's not reality. Things go wrong, parts break, a vacuum lines comes off the wastegate and you spike to 40psi (personal experience), etc etc and you gave your WRX to Ron and now don't have a daily driver because the STI broke. If I was you...I'd rebuild the WRX to make it a track car and then put stage 2 on the STI with a good tune. The WRX can break at will and the STI will be your reliable daily driver....or vice versa....de-mod the WRX to daily driver duty and make the STI a track car. |

Second option sounds better. Stronger platform to take the abuse, plus better gearing for the track (unless he's looking for drag).

a vacuum lines comes off the wastegate and you spike to 40psi (personal experience) EWG!! HEHE. jk, to late anyways boys! My UR GT35R kit will be here in a couple days along with my UR FMIC KIT, external fuel pump, injectors, fuel rails, AP V2, Tenzo DC-6wheels, ect. The party has started haha. Ron is gathering the parts together as we speak for the engine build. pistons, rods, cams, headwork, valvejob, springs, everything! FULLY BUILT BABY! 450whp on 93oct pumpgas and close to 600whp on RACEGAS. daily driver and track car all in one nice little package. ROn and Jorge will do the tune. Street putt putt around tune will be fairly conservative and racegas will be insane!!! Good luck with your setups and look for mine in the POWER BRAGING!!!! |
