    Well I'm a long time lurker that doesn't post much but I am not new to building bmw's. I've built and tuned a turbo e30 and m54b30 swapped e30 through my side tuning business. Its actually how I acquired this 94 325is coupe and a lot of other parts, my friend traded it to me for doing some work on his turbo e30 around 3 years ago.

    Most current pic when she not in a million pieces lol


    When I first got her


    Lets recap what I have already done in the last few years and start with the interior! I went ahead and removed what was left of the interior, dash and seats lol.


    Removed all sound deadening, airbag equipment(Installing Momo steering wheel), cruise control stuff, yes it all added up both garbage bags were almost 40lbs each lol. Removed any rust I found and I painted everything in rustoleum gloss black







    Since there was no headliner I painted the roof textured black.


    I then painted the tan dash and door panels with SEM Landau Black interior paint. I picked up some more tan interior pieces and carpet then painted those also. Scored a sweet Momo steering wheel off ebay for dirt cheap then got some pedals to match.




    Redid my gauge cluster with carbon vinyl wrap I had laying around, gauge rings and painted the needles red.


    End result..





    Now on to suspension! Picked up a full poly bushing set from Duraflex and all weld in reinforcements I could find.


    Found a good deal on some KW Variant 3 coilovers and some Vorshlag camber plates(yes i know wrong top hat nuts lol).



    Rear subframe dropped.


    Subframe reinforcements welded in.


    Subframe stripped, sway bar reinforcements welded in, painted, poly bushings installed.




    Found a mint e30 lsd for $150 on craigslist, so I took apart my diff painted it, installed the poly bushings in the cover, then the lsd with some Redline fluid.



    Rear subframe all back together and ready to install...Looking so sexy lol.


    Free Holset turbo what what!


    I got bored one day and decided to start shaving the engine bay, I'll finish it up when the engine is out.




    Yup and I had MS3Pro pnp on pre order...


    Tablet mounted for monitoring my engine and tweaking my tune on the fly.



    Now how she sits today, getting prepped for paint and new motor/trans....


    6 speed trans, m54b30 internals/motor parts, Wilwood brakes, and some of the other parts I've collected in the last few years.

    Picked up a $200 m50 non vanos engine over this last weekend and a m20b27 for another build.



    Took her apart and I got lucky everything inside looks very clean. Cylinder bores have absolutely no top ridge that i can feel. And thats actually one of the reasons I sourced a Non vanos m50 for my build, 7mm valves/dual valve springs/beefy rods and because they used non chrome plated piston rings unlike all the newer vanos motors which really wears the shit out of the cylinder walls. My vanos m50 cylinder walls were completely trashed.








    Today I also took apart and cleaned my s50 lifters that are going in. Picked up s50 trays/lifters/cams for $150 last year, proof that crazy deals are out there if you keep your eyes out! Thats a 35mm lifter on the left and 33mm on the right for a little comparison.

    Took some pics of how you modify a non vanos head to accept vanos if anyone was wondering how to. Easy 5 minute job with a grinder/dremel 👍

    Nice work but I do hope you have a plan for getting all that aluminum out of there. It’s going to be in all the oil gallery’s going into the rocker trays. Best thing to do would be to get it hot tanked at a machine shop. The alluminum shavings will all stick to the varnish coating the inside of the head and it will be a bear to get out till the varnish is removed.

    Yeah I tried to cover it up but it still got everywhere lol. I was planning on dropping it off at the machine shop to get fully disabled, tanked, checked and resurfaced anyways though 👍

    Good deal, sounds like a plan. A couple bath towels works good to catch the chips.

    Im pretty proud of that recipe. I know somebody that made 998 whp with that

    No M52 pistons. It blew up eventually from the rings butting. I used to run the same setup.

    Dang lol. Speaking of that what ring gap would you recommend running on these stock m54b30 pistons, I was thinking .020 top ring?

    I think mine are .018 top and .021 2nd or something close to that. The stock rings gaps are all over the place. They gap them at the factory with a machine before they go to the assembly line, they don't check every one, so the stock ones have a bit of variation.

    Ok cool I think Iíll shoot for .019 for the top ring then, I plan on doing some road racing with this setup so Iím a little nervous about the heat theyíre going to see on the track.

    Head back from the machine shop all clean, resurfaced and ready to go 👍





    Still working on notching the block out for the nv rods on s52/m54b30 crank. Itís been a very slow process using a tungsten carbide cutting bit. Probably should of paid my machine shop to do it...but Iím all about some diy lol.

    Got an air compressor? Get a die grinder. It will be much faster. Or a bigger diameter bit. An electric drill is too slow

    I do have both, that did cross my mind too I just didnít have the right chuck. But youíre right I need to go pick one up for it, would definitely work a million times better.

    When I realized I needed to notch my s52 block for the NV rods I took them back out and sold them then bought k1's. Call me lazy but I did not want to go through what you are haha

    With the right tools itís a pretty easy job, but yeah when you factor in the arp rod bolts itís not really much more to go h beams...But then Iíd wanna go forged pistons too lol, itís a damn slippery slope haha.

    Finally got around to getting some more work done on my engine. Honed the cylinder walls with a 240 grit Flex-Hone.




    Gapped my piston rings to .019 top and .024 2nd. Excuse the glossy paint I ended up stripping it off lol.


    I clean the deck, hosed the entire block out with degreaser and water to get anything left over from honing and notching, then I painted it again in a different more satin/textured black.


    Layed in new standard size King main bearings, installed the m54b30/s52 crank, plastigauged them, they looked to be around .0022 which is still within spec.







    Moved on to installing the m54b30 pistons/nv rods and ended up breaking one damn ring 🙄


    Went ahead and installed the other 5 pistons/rods with arp bolts and plastigauged the bearings. They looked to be around .0018, which is within spec.




    Now I have to wait for a replacement piston ring before I finish building the rest of it 🙄
