n54

I wasnt going to start a new thread but im having an issue, that i just can NOT figure out... I have no power to my interior (E92). No gauges, Gauges, Guage Cluster screen, and there's a constant "relay clicking" noise coming from the JBE area every 5 seconds or so. And currently this will...

Full FBO and MHD Wedge Tune. Was getting super duper shitty gas mileage - we talking 12mpg... Replaced all four o2 sensors and mileage shot back up like a rocket. Now 18-20 city and 23-24 highway. This is with down pipes. So if there is anyone who is wondering if changing o2 sensors after...

Hey guys, new here. Have a 335i 2007 E92 and there's no boost at all. Vacuum lines are already checked, selenoids are working, diverter valves are working as well, we've changed wastegate actuators and flaps, but there's still no boost. What else can we look into? Best regards

Maybe Im not the luckiest N54 owner been having a new issue each month. Couple of days ago i noticed some smoke behind the car when i was going a downhill like 2 min after i warmed up my car and drove. This happened today as well Im not sure what is the problem. The car doesnt smoke at startup...

A little something different for the masses that you don't see too often on the N54 is nitrous injection. There are turbo upgrades out of the Whoo-hah, but we wanted to do something different and go against the grain with this particular 335xi. Setup designed by us here at Twisted Tuning...

I feel like the 1 series form isnt as heavy as the 3 series or anything else really. Im curious to see where some of you guys are from. Post up a pic of your 1er, any mods, and location! Alberta, Canada.

Hey guys, so i wasnt to sure if this was normal or not, but everytime i start up my n54 135i (Bone stock atm), i get this lound raspy rattle in my exhaust. Only lasts for about a minuite or two until engine warms up, then its completely gone. To add more confusion to this all, if during the...

For sale is a set of Molnar Technologies connecting rods. I am using a set of these rods in my high hp build, designed for durability and abuse... they are beefy! The big end retains the OEM spec for bearings The small end is flat for the extra strength and not tapered like oem. After-market...

Hey guys, I created a Tumblr build thread but a few people asked me to do one here so here goes. I have built many cars. Mostly muscle but I love classic bugs and I've even done a couple turbo hondas... Hell, I've had more cars than years of life. I actually wanted a 1er since late 2012 but...

Hey guys i wanted to ask on opinions for quad exhaust set up for the 135i. Im currently running a 09 135i which i am planing on building as a show car, however my personall philosophy is that if a car looks mean, it better drive mean, so while i throw my money at this to look great, i do want...

Just stopping by to say Hi. Lurked for awhile, couldnt find my old account so made a new one. Ill post some pictures of the ride from the laptop! 09 335 M sport. Few mods :). More to come this winter. Stand by I cant figure this out on the cell, nooooooob

Got a used but totally flushed out with fresh ATF and coolant heat exchanger. Thermostat and all is working perfect. It's used so don't expect crazy shiny like in the picture included. That's just a sample image of the actual form factor.

Okay guys I was driving my car a little hard today. When all of a sudden my car went into limo mode. I check the codes via JB4: 2CF9 - throttle valve potentiometer 1 2CEC - throttle valve actuator , short locked 2CEE - throttle valve actuator , running rough 2CF7 - throttle valve potentiometer 2...

Hey guys I just installed the Precision Ignition upgrade on my car. I'm super happy with how the car feels now. I was getting crazy misfires before and somewhat of a rough idle but it runs mint now! I'm also working with EMP tuning so I can get the most power out of it. I made a DIY with some...

The 1/4" spacer offers superior thermal insulation between the cylinder head and the intake plenum. This can be useful when plumbing custom intercooler piping or rotating the intake manifold. This is a Must have for anyone running an Aluminum Aftermarket intake manifold. Which Heats up the...

Backed by popular demand, we are releasing pricing on our billet valve cover. Please read the post all the way through. We are a Canadian company, but we will be posting prices in USD on the forums as it's the biggest customer base. Plugging of PCV oil drain ports is highly recomended to avoid...

Just figured i would copy paste my R3v Thread here... Control F is your friend. Original thread: http://www.r3vlimited.com/board/showthread.php?t=327183 I tried laying it into this forum but too many pics, to many characters, etc.

Now that both ignition system upgraded have released it will be nice to gather and discuss all of the information possible. For example Plugs, gap, dwell, fuel, psi everyone is running and what has improved after ignition upgrade. I myself will be running PR Coils, PS2 High Flow @30psi with NGK...

New videos is finally up, it's a long one but it covers the entire install. Car is running mint, next couple vids will be doing the jb4 firmware/backend flash and fuel pump install. Hope you all enjoy!

Decided to take a crack at coming up with possible fixes of the failures for the N54/Early N55 HPFP's and possible upgrades and we all know they are needed for these cars. This will be a project I work on in the side, but through the tear down process is shows a lot and answers a few questions...
