    Well the good news keeps coming for the N55 crowd as we finished another product in our N55 line up the same time as our Stage 2 JB...:) We are extremely happy to announce our BRAND NEW VTT N55 STAGE 1 turbos. When we say brand new, what we mean is these turbos are not built from cores, we went through the process of having N55 compressor housings, Bearing housings, Turbine Wheels, compressor wheels, and internal parts, cast and manufactured, so we can now offer BRAND NEW N55 Stage 1 turbochargers with NO CORE CHARGE! These turbos are exactly the same specs as our previous Reman N55 stage ones which showed a consistent 40-70WHP increase in power, except of course built from brand new parts. What does this mean for our N55 stage 1 reman program? We will still be offering those units but at a new LOWER price and even cheaper core program...:naughty: The prices for our VTT Stage 1 turbos will now be as follows. VTT N55 Stage 1 turbo brand new no core: $1299 (IF you want to send us your core, we will give you back an additional $200 once we receive it! Bringing the price down to $1099 for a brand new turbo!) VTT N55 Stage 1 turbo Remanufactured: $799 with a $200 core That's right $799 for an N55 Stage 1 turbo, with only a $200 core! This now brings the N55 stage 1 upgrade into anyones price range. Having brand new units also means one more thing as well. NO WAITING! Since we do not have to send anything out to be machined or wait on cores, we can keep many units in stock and can ship the SAME DAY as they are ordered. We are scheduled to receive our first shipment of 15 Brand new N55 Stage 1's the first week in December, (these will be included in our Black Friday promotion for even more savings! :scared-eek::dance:) This is something that will surely change the N55 world as now turbo upgrades are truly affordable and available! We look forward to getting these into your hands, of course if you have any questions email Sales@vargasturbo.com for more info. Thanks! VTT

    Yeah and spec only rates their clutches at the flywheel, barely enough for maxed out stocked frames on E85 imo. The 3+ gets much easier to drive with time and i can engage it almost flawlessly now, but I have to try, sometimes it just wants to grab. The dual sounds awesome especially the cost to rebuild is stupidly cheap and seems like the way to go now if you don't want a stock feeling 5 series clutch. Please buy the bottom mount twin scroll mani for $1500 and let me know how it goes.

    Hello all you N55 faithful! We are excited to announce our N55 Stage 2 JB turbocharger is finished, and was sent off to its tester today to be ran through its paces. We are very excited for thise new Stage 2 offering for the N55, this brings the performance of a VTT Stage 2 DBB with a price that is much easier to swallow. For this upgrade we were able to keep the stock V-band flange, and V-band clamp! We machined around the existing flange and found a very efficient way to bolt on a much bigger and robust CHRA over stock, this JB option also uses all the same installation hardware as our DBB kits, so you get the same fit and finish the N55 DBB is known for but in a JB package. Some specs on the VTT N55 Stage 2 JB The wheels we have chosen are as follows Compressor wheel: Billet 6x6 Blade design 60.2MM inducer 78MM Exducer This makes the Jb turbo 2mm larger on the exducer than our DBB Stage 2 for slightly more flow. Turbine wheel: 11 blade design clipped to 12 degrees 61MM inducer 54MM Exducer This is 1mm bigger on the inducer, but 1mm smaller on the exducer for very similar flow and performance to our DBB Stage 2. The JB Stage 2 has the option for the upgraded Forge/VTT Billet DV, as well as our soon to be announced N55 waste gate upgrade. In the pictures below the JB sent out has the upgraded waste gate, and Billet DV options. We have no exact date for when these will be released, but with a successful testing program, we should have at least 2 units in stock ready to ship by the middle of Dec. The price for the VTT N55 Stage 2 JB unit be $2599 before options. We are confident this new offering will dominate the N55 landscape just as our DBB Stage 2 has. As always thank you for the continued support!

    I knew mine were damaged because of the internal DME failure code that was thrown. Also I've had coils fail before but never 3 at once.

    Negotiate with the insurance that you want to retain the car, than you won't have to start over from stock, you will still have your parts and you can sell the parts you don't want. If the car is truly totaled the insurance company will do nothing with it other than send it to a scrap yard, sometimes they will even prefer that the previous owner deals with the car. Talk to an attorney (if you family has one, call him) and he will explain how everything works.

    I'll find out in the next few days how much I'll get paid. I'm in college and want something reliable, but still fun. All I did was work to keep my m3 in the best possible shape so that's why I don't want to get another one and have to start over from stock

    Thanks for the offer Jon but I drove BostonShant's 135i with the Stage 3+ for reference. Its overall not bad, a little jerky from a stop but besides that not bad at all. Only concern is the torque that it holds because I'm planning on making more than the 630ft/lbs or whatever they rate it at. I was thinking of the PTF dual for stock feel and ability to hold more power but I'm still up in the air and want to hear more about the bolt issues and fitment as I read about which I believe you commented on about as well.

    Sirs, Does anyone have a specification sheet on 289074 JE pistons for S50B32? I lost mine. I need to know the exact bore clearance. It should be close to 0.005" or 0.12-0.13 mm for this model.

    geshsoft replied to a thread Need help with Fried MOSFETS in N54
    I am curious now - what is the FET failure mode? MOSFETs are usually damaged by exceeding Vds (drain-source voltage), Vgs (gate-source voltage), or Ids (drain-source current). Avalanching can also damage them but that is not very common. Over current condition would usually spell out load failure or wiring harness failure leading to intermittent or permanent shorting. Exceeding Vds is usually due to dirty power or improper reactive load driving (lack of snubbing, reverse transient protection, etc). Power FETs have built in reverse transient diodes in the form of body diodes that are good enough for most applications. Also, how do we know that the MOSFETs are damaged before the coil? If this is the case for sure the FETs can upgraded to a better part easily.

    Finally was able to convince them to replace the injectors, it's been a month and the car runs beautifully. Very happy. Starts very quickly with no misfire or abnormal operation, if I want to get VERY knit picky on warm starts it runs a little rough the first 5 seconds (almost undetectable), nothing I'd even complain about.

    What are you thinking for a replacement clutch kit? You are welcome to drive my stage 3+ if you want to try it out.

    haha that's actually exactly what I did yesterday but not because of cold start stumbles. My clutch is paying the price for running Wedges beastly e30 backend flash and until I get a new clutch in and my inspection is coming up, figured I would go back to stock flash for the time being to have all the monitors turned back on and drive my "slow" car for a little while :awesome:

    For misfire codes, especially when running a high boost tune I'd recommend NGK 5992 plugs gapped close. For jerking/stuttering with no code I would recommend datalogging, what I predict you will see is large timing pulls. I have seen that when exceeding or quickly approaching the load target/limit. Especially in colder weather when it's so much easier to get to the limit. PTF and Wedge may have better techniques but I have dealt with it by raising the load target/limit artificially high and then using the boost multiplier to avoid ever reaching the load target/limit. It has basically eliminated that for me at all times except extremely cold weather, when my artificially high limit still isn't high enough.

    Car is 09 335i N54 auto now about 111k miles. Walnut blast done about 35k miles ago New OEM type Bosch ZGR6STE2 about 5k miles ago New coils about 1k miles ago New injectors 1k miles ago New vacuum tubing about 5k miles ago Car has BB / Wedge flash, but saw no difference in stumble with stock (maybe slightly less). Tried swapping Diverter vales before replacing injectors to new ones and saw no change, car still stumble at low RPM, no issues on idle or at higher RPM. Stutter only when accelerating when cruising and hitting it, more so when there is no gear change (light acceleration). If I go WOT, at times it starts running like crap and starts misfiring along with check engine light. Restarting the car fixes misfiring. Sometimes codes show misfire cylinder 5, 1 and multiple misfires. At this point, I might try swapping DVs again, and next maybe replace charge pipe? It sounds very familiar as on this thread in E90post: http://www.e90post.com/forums/showthread.php?t=337084 Particularly this post: "Mine is interesting....it is not throwing any codes. From a stop, WOT no problem all the way through. However, when the car is cruising and you do the WOT it shudders/hesitates/hicups, feels thud sounds. But if you just accelerate slowly it's fine, it's when you accelerate fast it shudders again. Any ideas guys.....maybe i just need to live with this....." Any ideas / suggestions welcome.

    Looks like you are right, I found other people saying the 2 digits = Nm/10. That is weird... At any rate even the 530Nm rating for the N54 seems underrated, people have consistently put more torque through them than that without hurting gears right? The only trans problems I have heard about the 6MT's is synchro wear from banging shifts a ton.

    the last 2 digits are supposed to indicate torque capacity (measured how? who knows.. since the N54 one has shown to handle way more) - 53 being 530nm, 47 being 470nm.. n52 (at least uk/aus) 37bz being 370nm. Why they'd put a weaker trans in?.. It's a 100% parts bin car (bar the body kit), they had the N55 trans in current production.
