    Gold Standard of Weight Reduction - E90 on a Diet

    So the time has come to start weighing the car since round 1 of fab work is now complete! I thought 2700 lbs race weight without a driver was a bold goal when Efab Motorsports and I started down this path of extreme weight reduction. I think it is very possible this is the lightest E90 that...

    Technical Single Turbo O2 sensor install and data

    Thought I'd make a thread to collect some data on O2 sensor options for the single turbo peeps. As everyone knows, 2-bank fueling logic forces ST kits to place the pre-cat O2s in the manifold between the head and turbine, exposing them to extremely harsh high temperature and positive pressure...

    FS 2008 VM Single Turbo e92 - Low Miles - Clean Title in Hand

    Hey guys. I'm not really in a rush to sell it, but life and other circumstances are forcing me to re-evaluate my current situation. Please no crazy low offers. I stand to make absolutely nothing from selling and I am at a loss overall considering all the money I put into it after I bought it. I...

    Single Turbo E61 Build

    Alright I’m hopping back into the forum life, something which I haven’t been a part of since I used to ride motorcycles. Recently took the plunge and picked up a car I’ve wanted for a long while now. I’ve wanted an E61535xi ever since I ran across several build logs years and years ago. Well...

    zf6hp19 to zf8hp45 swap

    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...

    N54 Tunerpro DTC table confusion

    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...

    Top mounts in CA

    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...

    E8X Newest DCT Swapped N54 E82

    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...

    Double shotgun fuel pressure oscillation

    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...

    Precision Raceworks coil failure?

    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...
