    Basic upgrade order

    Sorry if it's been covered but since the knowledge base is still evolving, I thought i would ask -- assuming software is first on the list, is there any collective wisdom on which upgrades to make next (for horsepower) on a 335is/s? Thanks

    If you want the most horsepower for the least money: Tune > Meth > Nitrous > DCI > Downpipes > Intercooler > Rest of exhaust > Lightened Clutch/Flywheel > Light Wheels/Tires

    Diverter valves/Blow off valve may be needed if you start leaking boost past a certain pressure.

    If you want to avoid injecting meth and/or nitrous: Tune > DCI > Intercooler > Downpipes > Rest of exhaust > Lightened Clutch/Flywheel > Light Wheels/Tires

    I would go:
    OCC, FMIC, Tune, intake, downpipes, charge pipe and BOV, new rims and tires, LSD, exhaust.

    Personally now that I have the tune and the dual cone intakes, my next step is upgraded brakes, better tires, and maybe a larger oil cooler than I have with the sport package. The differences in approach will depend on what you want to do with the car. If you want to take it to the drag strip, by all means up the hp. If you want to take it to a track, I believe the weakness will be in the tires, the brakes, and the oil temperature before getting more hp. What's your mission?

    you cant go for that much power then with the n54, the early high torque will kill it without those SSP discs huh? 440 lb ft comes usually with 400-430 hp, doable on stock turbos.

    I don't think anyone with a DCT needs to worry on the N54 with the stock turbos. It can take more of a beating than people realize.

    If you want nitrous and to push it, you will need to upgrade the discs. Also if you want to use launch control all the time...

    so there is no after market HPFP. it just dies out when it feels the need to. and if it does warrantly wouldnt cover it if i had all the mods listed above on it i'm guessing. what would i need to do if somethign like this did happen and if failed.

    for now i gotta see what my price range is.. coupe is my fav but is pricier than the sedan:/

    correct, no aftermarket hpfp at this time. for people that have it fail, they need to de-mod and go to dealer(extend warranty for 110k miles i believe), or replace on their own $.

    ($25,500 fully loaded and fully modded, but i have 82k miles Click here to enlarge )

    The HPFP deal isn't as bad as people make it out to be......

    It would be like not buying a Jetta because of coil-packs that randomly fail.

    lol we'll that happend to my gti.the coil was only 40 bucks.

    i for sure know a HPFP for a bimmer will not be less than 1k. esp when it needs to be installed by a profesh.
    and i have to de-mod my car just because of it... if i want to go with warranty. so either way its gonna be pricey if that does go down. burn.

    If your vehicle has the wrong pump it is recalled anyway, regardless of mod status.

    yup, RB turbos's meth FBO, LSD, everyhting you could want.. and as for hpfp, original was replaced at 44k miles, ive owned the car since 48k miles and im still on that one.. im 6AT btw Click here to enlarge

    the pump itself i believe is about $3-400 and probably about the same for install if not doing it yourself, which there are DIY on that

    even if you didnt, and the car is out of normal warranty, you would still go get the latest, modded or not they have to give it to you

    Exactly.

    People make this out to be much of a bigger deal than it is. They HAVE to check out your pump and replace it if necessary (if not the latest pump type, I think 943 or something), regardless of whether you have mods of not.
