single turbo

Hi everyone and Happy New Year! I drive a single turbo (6266) e92 335xi fitted with the infamously sluggish zf6hp19 6-speed auto that can't hold power, and it's slipping with only 18psi. Instead of doing a rebuild or swapping to a manual (it's my daily and I live in busy NYC) I thought of doing...

I'm trying to disable some O2 emissions system check codes to diagnose my car. It's giving me a lot of grief throwing heater, function, system check, etc. codes for the Pre-cat O2 sensors on my single turbo setup. AFRs will lean out and it'll drive like s#&t until the codes are cleared. All the...

Have talked to a few people who run bottom mount kits in CA. Wondering if anyone is running a top mount single turbo kit in CA and how it’s going for them with smog? Not as much worried about the visual. I know in other states you can get a top mount single kit to pass smog but CA is a bit more...

OVERVIEW Hello, first time posting here, although I have been lurking for some time! This thread is to show people a real-world cost of doing a budget single turbo build. In the end, it ended up costing less than I expected. In the cost analysis, I will include my complete cost, including...

I introduce the newest DCT swapped N54 e82 to the club. The car has undergone a full track prep over the winter but the last piece of the puzzle was getting the transmission that I wanted in there, the DCT. I absolutely could not have done this swap without @BMWJunkie! For those of you who don't...

I have recently finished installing my VTTO double shotgun kit. The car runs good and has all the fuel pressure, but I’ve noticed the FP_H fluctuating during pulls and i was wondering if anyone has seen this. I’m currently running an ots bef (St_e85_THR) while i wait for my wedge tune. Is it...

I’m looking for some insight. I recently developed a cylinder 6 and 5 misfire. Cylinder 6 was intermittent under load and cylinder 5 started misfiring intermittently as well but eventually became a constant misfire (Even at idle). I just started running full e85 after installing a double shotgun...

I've been deep into this topic recently and discovered that there's not much information out there so I wanted to create a place where people that self tune can have a discussion on the topic. I'm using a boostbox V3 to tune my car, and have only began tuning at the moment. I enjoy the...

Good morning SpoolStreet members. Granted beating a dead horse isn't the best way to approach this, but i've been very busy these past few weeks since the EMP tune fiasco, and would like to share my story and how it was righted, but no thanks to EMP I have been running an emp bef on my ST n54...

hey guys first time poster but longish time lurker. I bought my 07 335i sedan about years ago and recently I purchased my VM single turbo kit. But I am very OCD when it comes to my baby. so I don't want any surprises when installing this kit. so the point of this post is basically, what am I...

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!

Hey guys if anyone is interested I'm going to be documenting my single turbo install on YouTube. If you subscribe to my channel "Budget Bimmers" I'll be uploading the series within the next few weeks. I'm also going to be installing a spec stage 3+ clutch with an mfactory single mass flywheel...

Well this is something I've been working on for several months in the background of everything else going on here at Twisted Tuning. I've mentioned this little project (probably larger meaning to some) to a couple people here and there but never made an actual post about it. The N54 game has...

Hello Spoolstreet! I thought I would introduce my company to you guys and tell you about some of the awesome stuff Arsenal Motorsports & Engineering has been developing for quite some time. To start off, Arsenal Motorsports & Engineering was started about a year ago by a couple of BMW...

Car is a 2007 e90 335i with the n54 motor, automatic trans. Was purchased stock with 97k miles 2 years ago. Slowly began modding it up to a fbo car running e60 fuel. Turbos began to leak and smoke so recently I did a conversion to a top mounted Precision 6266 1.0ar turbo, with 2 Tial wastegates...
