    Admittedly, its not an e30, but with my ti I definitely prefer the resonator w/the Stromung. I have a Magnaflow cat, ultra quiet, then Stromung. Its still a bit loud on the highway though has no drone below 55-60mph.

    Sounds like a great plan on the Classic Daily work...
    Sadly someone cut the converter off, and with the price of a 50 state legal converter I planned on putting a resonator in its place. Perhaps, since this car is going to be sold off, it may be best to put a cat in to make it easier on the next owner.

    We were hoping to tune Linda on his dyno & fix battery box rust before winter, but he ended up selling his old dyno and is transitioning to a newer dynojet! So I’m just going to wait until post-winter to take care of that, and get hoopty 5sp and on megasquirt in the meantime!

    In other hoopty news, hoopty #5 (325iS) is going to cruise up with me to the ClassicDaily HQ some time this winter where we will be manual swapping and doing a before/after dyno Megasquirt conversion! Will likely report back this weekend (bday is sunday), with whatever I'm able to get done over the next few days. Coilovers are welded, should be able to build them and get them on the car, maybe get m42 hoopty running, etc etc. We'll see!

Add lightness and good things happen.
    Thanks, man! With how much I ended up having to do to the car, I think it will be rewarding to see it/feel it finished up. I am planning on keeping it around for a bit to experience the car with the 4cyl when it's done to 'say I did', and work out any kinks that may arise. The goal was to get it sold before winter, but now that we've already had one snow, it doesn't look like that's going to happen, so I won't be offended if it hangs out until winter passes.

    I am excited as well! Just "handling" the engine/trans when putting it in the car gave me a perspective on how light it is. Curious to see how it all translates to the drive, overall.

    Bummer on the front coils but it will be all worth it in the end and it will be right.

    I kinda like the Ronals without the caps...maybe paint the center lug dished area black or dark metallic gray?
    Bahaha I love it- if it didn't take time it would make for a hilarious photoshoot.

    Yep, I had a similar thought about doing black or nogaro centers, akin to many of the Alpina wheels!


    Prepped hoopte #5's original housings to get welded! Came apart like buttah. I love working on cars that havent been showered in brine all of their life.

    Gettin' hoopte #4's new M42 together! Prepped a bunch of small stuff, mapped out all of my new hoses for the "mess under intake" simplification, etc. The new M42 had some head work done recently and also has a coil on plug conversion. I hate to admit this because #m20life but I feel like an M42 stroker would be a really neat motor with how light these things are. There is just so much room for activities, and the weight difference between m20 and m42 is more noticeable than I thought. The more I work on this car, the more it seems like it doesn't have many miles. Lots of small things are very clean/pliable/etc that I didn't notice initially. I didn't get a cluster with the car, so it's TMU, but it shows better than all of the 100-150k mile cars I've had.

    I’m not sure if they’re selling stuff on eBay, but it was just a shop in Indy that called and said “hey you’re the guy that buys everyone’s old BMW parts right?” And of course I said, “Sure am!”.

    They were going to scrap the stuff so they just offered it to me for scrap price so it didn’t get crushed. Bunch of really cool NOS piece that they used to keep in stock 20 years ago.

    Got the NOS (free and beat up) ansa catback on and went for a spin. I think these Ronals look quite nice with the studs, without the caps. Not for every application, but no caps and studs feels at home here.... goes with the vibe.

    I'm going to have to roll the rear fenders, but I think it looks good! I broke down and ordered front Konis so I can do the front GCs right, do it once, and be done.

    Maaan I am right there with you- just m30 instead of m10- a ratty early car build would be a fun one!


    Parted/sent another car off to the yard to make some room.

    Much better

    So, if you have ever spent more than 30 seconds in a build thread of mine, you are aware of my debilitating habit of taking on new projects for no reason that effectively completely distract me from the other missions at hand. I have done it again.

    I purchased the track car because it was claimed to have a nice set of GCs and a slew of other good parts to "quick swap onto hoopte". I couldn't get the rear GC adjusters off of the TAs and noticed it had eccentric TA bushings and new powerflex subframe bushings, which led me to swap the entire subframe assembly (incl small case s4.1) into hoopte just to get the rear coils, further justified by the fact that I had a new old stock ANSA catback to replace the rotted one, so I had to "drop the exhaust anyway". I then noticed the rear axles were non-abs so i had to swap those out, rebuild ebrake assemblies, etc etc. Getting the d/s on the diff was a huge pain, and ended up converting the diff to studs and macgyver-ing it in the subframe whilst lining up d/s studs so I didn't have to collapse the d/s.

    It was at this point that I realized I shouldn't have done any of this and should've left hoopte well enough alone that I wanted to just pull the front GCs off of the track car and toss them on hoopte and be done, so I went to do so and found out that the "nice GCs" were trash heaps built on 45mm non-abs strut housings and needed to be totally redone. So now hoopte is low in the back and high in the front, the brakes won't bleed right, and the other 95 projects that I have are left untouched as usual. If I said "lesson learned", I'd just be lying.

    Pulling a subframe in the rain was super fun:

    Almost there:

    Lowrider. I adjusted it 6 turns up from this height and may still go higher once I see how front clearance is after I finish rebuilding the front coils on 51mm housings.
