    It would take a miracle. You would void out your warranty anyways because of the other mods you would need to get times like that (i.e. BC, Headers, Uppipe, Exhaust, etc). If you're going to do all that, might as well get a bigger turbo.

    Bro, I'm not flaming you but you definitely need to get your priorities in order. What is more important to you right now, beating a Grand National or voiding your warranty? You are not going to get one without the other. You seem to have the attitude that as long as you leave your stock turbo in place you will still have your warranty. That is not correct, there are plenty of things outside of an upgraded turbo that will void the warranty. Something as simple as a cold air intake or exhaust will void parts of your warranty. A lighter/underdriven crank or alternator pulley can void portions of your warranty. The answer is not black and white, there's a lot of room for interpretation. If your Subaru dealer is a jerk and not "open minded" when it comes to mods they will frown upon any aftermarket part that you install in your car.

    Well most mods I think I can put back to norm before I goto the dealer E.G. exhaust, intake etc; and only if something breaks.I dont want to change anything that is too hard to revert in a day or two.Are stock GN's that fast.I just want to run maybe a 13.4 & I will be happy.What does that take??

    Grand Nationals are very fast cars, especially if they are worked.

    It is possible to get into the low 13s without upgrading the turbo, you just have to do everything else:
    boost controller, air filter, uppipe, IC hoses, good downpipe and/or turboback exhaust, a Unichip and an upgraded intercooler wouldn't hurt either.

    I'm planning on wringing as much power out of the stock turbo as possible before I upgrade.

    I'm positive that my catless uppipe will put me past my first goal of <13.5s and 100+ mph in the 1/4 mile.
    I will be smashing this goal in mid-July.

    My current best was 13.650s@99.11mph. You can read about my recent runs and my mods below.

    As a matter of fact flyboy, you have the mods that I want to get!!The uppipe seems like the ***** out of the bunch to revert, but if I blew my tranny I think
    I may find the strength to do it !What do you run and can you beat a stock GN??

    Believe me, once you install that uppipe you will not want to remove it.

    I have no idea what it runs, I'm probably going to take it to the track after I get my downpipe. I'm just guessing on this but I would say that anything below a 13.6 should beat a stock GN. Anyone with real life experience care to give feedback?

    If you want to start beating GN's, and run low 13's its actually VERY easy to run low 13's with the proper mods... A friend of mine ran a 13.3 with just a turboback and MBC... I am not a firm beleiver in the unichip with the STOCK turbo, i think its really unnecassary until your running larger turbos with much larger PSI.. Warranty, well, i could care less about my warranty, but thats just me, the only thing that will void it is if somthing goes wrong that is pertaining to your mods... Like just recently i took my car to the dealer to have them fix my mirror that keeps flipping loosely, dident say anything about my mods, covered the mirror under warranty, and i was on my way... No talks about putting me on there "****list" for having mods or anything.. Just asked me kindly not to cut into the little "Green" wires under the dash because they lead to the conector where the dealer can troubleshoot the car .... U can always jsut take your mbc off when u goto the dealer.. But if you going to do mods and somthing goes wrong, theres no reason they should cover it your takin that risk.. Good luck... MBC turbo back samco hoses uppipe should get you way into the low 13's if you know how to shift

    I think ive heard somewhere (maybe i-club) of wrx's with stock turbos runnin in the 12's. I know there are some definetly runnin low 13's with stock turbo.

    Not exactly sure, but it rings a bell.

    Do a search on i-club, there is someone who just set a new stock turbo record around 12.5...this is a usa record, there is a guy that ran 11.89 in England...but he is fooling the computer and running 23 psi boost with a custom intercooler and a liqid injection system (INTO the intercooler). His name is cosie convert. His WRX is just to tow his race car!

    This is absolute BS. The stock turbo can NOT produce 23 psi of boost. Maybe it was a VF30 powered WRX STi or similar grey market subaru.

    The US stock turbo record was set using nitrous oxide.

    Jim, this is a pretty heated debate going on at I-Club...Jorge (Rifts) was the one who told us all about it, but the majority of everyone is pretty much with you on this...

    You will probably not say that when your transmission starts to fail like so many people on i-club. Good luck on shelling out 2-3 grand when that happens.
