    Great track day yesterday, Turn 2 "late apexing" at the Ridge. $300 for a few 30 minute sessions followed by OPEN TRACK from 5-8pm, it was an all-you-can-eat buffet of driving!

    I'm getting used to the Mk60E5 ABS and it is amazing; it's the German hand of God.

    I had also added a Derale heatsink power steering cooler and I was really pleased with how well it works. With the stock E90 power steering pump and pulley, back in the day, I was exceeding 300F at my first track events with the N52, plus the steering was overboosted. A reduction in pressure with a 100bar Cayman regulator got the temps down to 270F which is still hot.

    I never saw anything over 200F yesterday and I will call this "sorted". My other option was to run a small radiator in front but I don't necessarily want the extra plumbing. Dunno, but this seems fine mounted on the frame rail and it's pretty out of the way.

    Probably disconnect the swaybars incase they are preloading.
    I couldn't sit in the seat without maxing the scale, so I put 100lbs in the seat in addition to each empty corner reading, then I doubled the difference to come up with the attached.

    Error is probably +/-5lbs per wheel, but it's pretty close. I mean, when I do a home alignment and then get it professionally done I'm usually within a tenth of a degree.

    As far as the 54%, while I've taken a lot of weight off the nose, I've taken even more out of the back. Trunk tar, tools and battery alone is probably 80lbs. A CF hood will get me closer to 53%.

    In any case, Nissan says 54% is "perfect", so there ya go.... https://www.reddit.com/r/cars/commen...erfect_weight/

    Very nice, when my car runs (I need to stop saying that) I look forward to borrowing some scales so I can get a real weight for mine too.

    I've been trying to do a proper corner weight of my car for a while now, all I've known is that I cross the big scales at 2700# and that my car is around 2470#

    Short of proper corner scales, I bought a $50 Amazon 700# scale and leveled the car. I rolled it back and forth each time I moved the scale to unbind the suspension, measuring 1 wheel at a time. (the other 3 wheels were on lumber to match the scale height)

    N52 (obviously), no A/C, no sunroof, 2 Sparco seats, no radio or speakers. no tar. rear seat delete.

    Full carpet, full tank of gas, spare.

    Power steering moved to trunk, 38# lead battery replaced by 6# lithium.

    If I remove the spare my full-up track weight is 2400 with a full tank.

There's a few posts specific to wiring, but it was mentioned it was trivial in comparison to mocking up the oil pan and arms.




    LOL that would be hilarious if that happened here. Typically for engine swaps in California they can either be dirty smogged or legitimately done through a BAR Referee. From what I read, they go through your swap with a fine tooth comb, looking for anything out of place, non-OEM, aftermarket, non CARB approved items. All emissions related equipment must be fully functional.

    On top of the emissions portion, they require that the DME be verified by a BMW dealership to confirm nothing has been altered. I'm reading some will waive the EWS delete, as they understand it is not emissions related. This is copy from another thread on here: "I received your letter and forwarded it to BAR. They requested that the info be put on a dealer invoice. They want verification that the PCM is for a 1999 BMW M3 CA cert. The BAR would like the dealer to list the Calibration ID (CAL ID) and Calibration verification number (CVN) as well."

    Full discussion of here on another thread. I posted the question a few months ago regarding getting a swapped N52/4/5 BAR'd, but no one responded. I'm assuming no one on here has done so yet?​

    I'm opting to do it correctly, as this would be my daily driver.

    This is also my first engine swap, so I have plenty to learn here. I'm grateful for this platform and all that have contributed to the discussion, it's really given me a lot of confidence to try something new.
    Pretty sure no one has - the biggest challenge will be all the gas tank related modifications.

    Hello again! Feeling a new spark of motivation with all these new developments I keep hearing about. Finally started pulling the trigger on some parts: IVM, z4 pedal, and engine arms.

    Hoping to sell my S52 car shortly and roll the slicktop into the middle of the shop for some amateur rust repair before I start getting into the motor.

    Loving all the progress in the new sub!

    -Peter

    It's not much, but here is something for you all. I printed this and slapped it up in the garage when I was sorting things.

    The WDS and images for the IVM require squinting and second guessing. This makes it simple, at least for my configuration.

    Anywhere I can, I want to add clarity for the next guy.

    Yes, it's important to do it right. If I lived in Cali, I would've had to learn what you are talking about. I would try to talk with a 'referee' ahead of time if possible.

    My swap retains all of those components. I didn't remove anything from the N52 except the rear O2 sensor pair. If it is an issue, you'll have to construct an exhaust that will fit a couple more O2 sensors after the cat(s).

    I would think that if you do a good job and tidy everything up with the above mentioned stuff all plugged in and the motor is running good..... The tail pipe emissions should be no problem for a 30+ year old car and the standards they are held to.

    I mounted my OBD under the steering wheel on the kick panel. In hindsight, it should be in or near the glove box so the cable doesn't have to reach across everything if you want to place the laptop on the passenger seat.

    When I went to get the car tested.... I just presented it as a 1988 car. They hooked up the sniffer and ran it on a dyno, driving it though the gears. After that, they looked at everything under the hood and under the car. Didn't say anything about what obviously didn't belong. I passed because of the emissions and I had everything they were looking for on the checklist. Not sure if it would have turned out the same if I had pointed out the OBD port and suggested they hook it up. But 1988 cars don't have an OBD port..... ;-)

    Not sure about emissions, although Luke is running catalytic converters, just not the ones original to the N52.
