    My 325i 4door (S52 swap in progress)

    I am not sure why I never really got around to posting this, but I'm going to pretty much copy and paste the progress until now from some local boards I frequent. This is not going to be some incredible 500+hp build, but a lot of work has gone into this car and I'm very proud of it.

    Backstory:
    Picked up this hardly cared for black on grey cloth comfort automatic 325i sedan a little over a year ago with a grenaded top end.





    Tossed it on a friends car trailer and drove it home, spent a couple months tearing in and swapping everything worth keeping from the eta. We pulled the motor from the new project in advance to save time on the install day.




    The eta was then driven to a friend's house where it was ruthlessly gutted, taking a few important bits to bring new life to my sedan, most importantly the 5 speed conversion parts (save for the early model trans)




    I sent the intake manifold and valve cover out for powder coating, the head was cleaned up and the motor went back together with all new seals top to bottom.






    With the old car gone, I again turned my attention to the re assembly of my 1990. The interior was buttoned up, the motor and trans were installed, and on its first attempt the car fired up




    Had some buddies at a local shop install my H&R sports/bilsteins, mounted some S-drives on my racing dynamics, and started to daily the car.



    I basically spent the next year doing whatever upgrades floated my boat along with a fantastic SCC course



    Reinforced mount tabs for the rear swaybar



    New wheel bearing kits for both sides, installed as far as I can without swapping over the brake parts during install.





    Bimmerworld 22mm/19mm swaybars



    E36 rack swap and all new front steering/bushing parts



    Cocomats



    Drove the car hard on a local track for a weekend during a 3 day training course













    Grabbed race take-offs for my extra set of 15" RD's



    Removed dust shields to help with brake cooling on track



    IE strut brace and KAmotors intake. I had lots of front tower sag when installing the bar, this drastically changed the turn in response.




    Relocated window lock switch to dash and installed heated seat switches. Car has cupholders in factory seat heater button locations







    Had a set of vert leather seats reupholstered in iS pattern, replaced seat shocks and heater elements with new units during install.



    That brings us up to date. I woke up one morning with an urge to do another engine replacement, so I decided to follow the dream I've had since day one with my old 318is and install a 24v powerplant. Snagged an S52 for a reasonable price and started.



    Engine was torn down and cleaned up with a host of new parts. CCVV, plugs, coil boots, top/bottom gasket sets, waterpump, thermostat, idler, e34 oil pan, e39 M52 fuel rail w/fpr, vanos rebuild and other stuff. I've decided to keep the original OBD2 intake manifold as the engine is powerful enough to have fun with as is and I can always do the swap later down the road if I change my mind. DME has been sent to Markert for re-tuning and should be returning later this week. Install set to begin next weekend unless something big pops up.

























    Re-assembly












    Assembled!

    If you look closely you'll notice I started painting things as I was taking them apart, realized I was going to have difficulty getting the timing covers and head to match without some potential sealing issues on various things and decided to leave it.





    (Yes I know the motor mount arm is upside down in this picture! Thanks to Dave for pointing that out)


    Wiring!

    OBD2 wiring harness modified to put required wires from e36 x20 and x6031 connectors into an e30 C101 for plug and play install. Not pictured is the A/C run/pressure switch wires re-routed to follow the x6000 into the glovebox






    Parts!
    Not pictured here are the new brakes, ix booster/master, 318is firewall cover, more clutch parts, alternator, starter, trans mounts and a bunch of other stuff. Too many small shipments for me to care about posting them all honestly.

    S52 conversion began this morning, so far most is going well except for a few parts that are yet to arrive. I believe I have found backups for them so I should be able to continue with the flywheel/clutch and trans install tomorrow. I hope to see it all back in the car by night time.

    10am, arrived at the shop for my 302,000km service


    I thought I was undoing the oil drain plug but somehow all of this came out with it. It was a long day doing the removal alone and fighting a weak knee but I took it slow and got it. A few good buddies came by to offer support in the way of insults and a some help with getting the S52 installed on the subframe. Special thanks to the guys at German Auto Sports in Surrey BC for the after hours parts delivery and advice!

      Engine in on Saturday, slowly plugging away at all the little stuff now. Sadly my weekend is over so progress will be limited to a couple hours a day.

      Had the flywheel machined, new clutch, trans installed, and got to putting things back together. Exhaust clearance is... interesting, the shop is going to have fun getting it fitted for sure or I'll pickup some other alternative setup if need be.

        It runs! Second start today, just a test with things halfway pieced together. I need to swap to the m50 manifold to make my throttle cable work but knowing the electrical and motor itself are working is a huge relief. Don't mind the headlight, it was just unplugged.
