    Hey guys, A little good news, around 18 months in the making. We finally received formal CARB approval for our N54 dual cone intake system! This adds to our N55 Stage1 tuner and N18 JB+ that are also 50 state legal. With more products in the process. :burnrubber: CARB Approved Under Executive Order (EO) No. D-744-2 for all 2007-2012 BMW Models Equipped with the N54 3.0L twin-turbocharged 6-cylinder engine.

    The other day BoostAddict posted an article regarding Weistec's legal action against Dime Research and Development or Dime Consulting. Clearly those involved with Dime realize the walls are closing in so what are they doing in the meantime while the courts play this out? BS'ing people on forums and trying to do as much damage to Weistec as possible. It's a very simple recipe and it happens more often than you think. Simply offer someone some parts for a discount or free in exchange for posting a thread including a positive review while bashing a competitor. It happens all the time. MHP was the best at this. The owner even asked me directly to create fake accounts for him on other forums so he could do this. When a ship is sinking which in this case it is a company it takes cash to stay afloat or keep the doors open. When HPF (Horsepower Freaks) was in a similar position the owner would go on the forums and post videos of how his shop was filled with cars hoping to instill confidence in potential customers. It's easy to see through the BS though if you have enough experience or have been on the forums long enough. In this instance, it was way too easy: This 'Guilty' fellow posts a graph claiming it is a C63 M177, bashes Weistec, and says how great his tune is. That tune curve looks pretty familiar though, doesn't it? Very similar but not the exact figures yet clearly an AMG GT M178 graph and not a C63 M177 graph. If it was the exact same graph as the graph Weistec advertises with that would be too obvious even to your typical forum moron. Maybe they took another run file or just changed a correction factor? If we had the actual bevvy of dyno run files from the Dynojet software testing we could prove this. Oh, it just so happens we do: That would be runfile 88 from Weistec's ECU tuning. Exact same baseline and the exact same after the tune numbers. Because it's the exact same files. This poor schmuck is either a Dime schill or he believes that is the runfile for his car. Either way the guys reading on forums just assume this is the truth and that they can get the same results as Weistec for less money. If the software is stolen and no development work took place, yep, it's possible to offer a lower price. For those who would like to verify for themselves, here are the Dynojet run files: RunFile_002_stock.drf RunFile_088_Testing.drf As stated, it's a simple recipe. Post a graph, have a few fake accounts chime in where the administration doesn't care because it's too big to care, and you get the desired result which is herding the sheep in the direction you want them to go. Now tell me, who would you trust? The company facing litigation from multiple parties with people involved accused of stealing millions and potentially funneling money overseas that advertises software they did not even develop or BenzBoost? Hmm: It seems not everyone is so easily swayed:

    N54 Community, Most of my updates are posted in my build log but I figured this was interesting enough and deserved it's own thread. My E61 Build Thread: I also hope this is motivational for those debating whether to pull the trigger on a big project like an engine swap, trans swap, whatever. Go for it! BMW forums are filled with people advising others to "sell your car and just buy a manual one," where the reality is these "advisors" have never done the swap or have any first hand experience with the intricacies of the project, it seems their advice is driven by fear of the unknown. Furthermore, the sense of accomplishment with tackling projects yourself is worth it all by itself, not to mention the knowledge gained or the money saved on labor. *steps off soapbox* So it has been about 4 months since I blew my motor: Prior to my engine exploding I was collecting parts for my AT-MT conversion as well as an AWD-RWD conversion with all M5 components. A blown motor is never convenient but the timing worked out well as I was in a position where I could undertake all projects at once which has certain advantages. My wrenching skills and understanding of the E6X/N54 platforms have been developing and although all of these relatively major projects were beyond the scope of work I had previously done, I felt I could pull it off with ample due-diligence and patience. I mean it's all nuts and bolts right? I don't have plans to take the HP/TQ much past what it was previously (~550-600whp) for my intended use as a daily-driven weapon, that power is ample and it think it is a good range where the stock internal N54 can manage the load/stress. It seems >600whp is where wear and tear are really amplified. My goal was to find a N54 long block with low-moderate (<75,000) miles on it, $2,000 or less was the price I was hunting for. Many people sarcastically wished me luck or simply said that it was not possible; I am a competitive person by nature so this feedback only fueled my interest in succeeding thanks! As all the naysayers would have it, most of the engines that met my criteria were in the $3,000-$4,000 range. The best deal I had found after a month or so of casual searching was a 535xi engine w/76k and a 6 month part warranty for $2,650 shipped from Canada (shipping was $230 or so). Not a bad deal but I passed. I ended up finding an ad on Craigslist for an N54 engine out in Fontana for $800, no picture or additional information listed but after contacting the seller they confirmed with was an N54 from a 2011 335is and had 35k on it. I went immediately to view the engine in person. The engine was complete minus the turbos and had been in an accident where the car was totaled, there was some damage to the exterior components, oil pan, and valve cover. As it was, $800 was still a great deal and if the engine was a flop I could likely part it out and break even financially. Oddly enough the CL ad was posted for over 3 months, there had been multiple buyers but all of them were scared off by the damage. I bought the engine for $800, paid $100 for it to be shipped to my house later that day, and tipped the high schooler who delivered it $40. So $940 shipped to my garage, not bad. After the initial tear down I sold the oil filter housing, wiring harness, HPFP, and i12 injectors for $950 so I know had a free N54 engine. My main concern was the block and head which after examining the damage inflicted to the engine from the crash, should still be good, I confirmed this with some "good enough" leak down tests and continued ordering parts to rebuild the front side of the engine: timing chain, cogs, oil and vacuum pump drive system, etc. All of the other engine components would be transferred over from my blown motor. Rebuild Parts List Chains, sprockets, gears: $170 Oil pan gasket, hardware: $85 Used "eBay 535i oil pan: $220 TOTAL: $475 Since the engine is still out of the wagon and it has not yet been started, ran, or tuned to confirm function, WE WILL SEE if this all plays out or if the joke's on me (naysayers patiently waiting). As it stands now, $465 for an N54 with <35k on it is a deal I am very happy with. On to the pics! Evan Replacement engine home for the first time: Stripping down the engine. Most components were damaged but some were not. A better look at the damage on the bottom. You cans ee the stress cracks in the cog and also the impact marks on the chain and chain guide. Valve cover damage Thankfully it was only superficial to the cover There was some mild contamination inside the engine from the holes in the oil pan + sitting in a junkyard for a few months The rest of the engine looked great internally Peaking up a cylinder Engine stripped down and exterior cleaned There was a broken oil pan bolt which needed to be rescued The as-is leak down test yielded terrible results so I oiled up the cylinder walls and retested. There were some variation with the reading on 2 cylinders but they had audible intake valve leak (inconsistent) and since I can't fire up the engine to get it up to operating temp, possibly clean gunk, and improve valve seat, the numbers were "good enough" for me to continue with the rebuild. 1% 12% 8% 4% 6% 12% Next up was cleaning the valves 1 2 3 4 5 6 Annie the dog is not amused New oil pan arrived, it is in much better condition than the others Tech Tip: A used subframe bolt works well as a counterhold in the Harbor Freight engine stand. I would still recommend a proper hub counterhold but this certainly helps. Didn't have the proper tool to remove this vacuum pump gear access plug from the front and on my old engine I was able to pop it out from the inside (working by the oil pump) with a long pry bar. Knowing I had an extra one to use, this one got the dremel. Got it! Camshaft lock installed Chainguide mounting plugs removed Timing chain tensioner removed, make sure to pump it a few times to evacuate old oil and also replace the aluminum seal. Hub counter hold and breaker bar with 22mm socket Teamwork Interesting build up, my 535xi engine with 105k didn't have anything like this Vanos sensors removed and cleaned Removing Vanos units Vanos, timing chain, and chain guide removed Vanos cleaned Vacuum and oil pump drive system removed Closer at the oil pump drive damage Bent cog vs new Chain guide damage from chain tension An oversight on my part but there are subtle differences between some N54 hubs and sprockets 535xi cog left, 335is right, the friction/spacer design is also different but most importantly the 335is cogs I ordered would not fit on the 535xi style hub I bought so I ended up running the original 335is hub with new cogs. Workspace N54 guts With frontside components removed I cleaned the engine as much as I could with rags and compressed air Much better now I used my old lower chain guide as it didn't have any damage and installed all new drive components Oil pump in. I reused the 335is pump as it had no noticeable damage and had 1/3 the mileage of my 535xi unit. Drive system in Timing chain and vanos back in Camshaft sensors and timing tool installed Crank hub in Timing chain pre-tensioned Torqued to spec (torque + 180) Oil pump, pickup, and baffle installed and torqued Oil pan gasket Oil pan installed and torqued Inspected and cleaned all pulleys. They collect little mounds of dirt over time so removing that should lighten the pulleys and improve performance right? +5hp? Before/After Installed Belt tensioner installed Had a roque/stripped manifold stud to remove #Tools Hard to reach places and specifc torque angles + low load specs Valve cover on Let's see how well I organized my oem nuts and bolts... Alternator and compressor installed Oil filter housing service. I had a set of new gaskets sitting for over year so this was an IDEAL time to install them, lol. New filter and the BMS bypass valve Gotta love machined metal My low mileage i12 injectors cleaned and installed New set of NGKs needed to be gapped. I have 2 different gap tools and they both suck, this is by far the best way I have found to lower the gap. Delphi coils and plugs installed HPFP, fuel rail, and engine mount installed Starting to look like a normal N54

    Agreed. For what it's worth, Carfection's review of the M4 GTS showed it lined up against a standard M4 and they said the GTS was "way faster." But then they didn't show the race...:crazy:

    The new Pure S2 definitely hold power on top better than the S1 upgrade, We currently are playing with a set of those, got that tail to lift as Allmotor said close to 100whp. Once we are done dialing in wastegates tables to get the boost curve we are looking for, a little less humid weather, we will then start pushing for peak numbers. My only concern is that we might be getting close to finally see the fueling limitations of the stock S63tu, Little soon to say for sure but, for a fact, Ethanol content has to be looked at closely now, when before was never a actual concern. Which is the biggest proof of how more efficient this S2 turbos are compared to the S1.
