I went today just to have a look. Engine and gearbox were already removed - and they aren't listed in the sold section. I would say Pickapart is selling those separately - or got the car in a deal whereby they got the car minus the drivetrain. Anything M5 specific is basically already gone. The air boxes are still there along with the alcantara headliner and the seats. Although someone has used the back seat cushion to lie on when removing the diff. Rear brakes were still there and rear axles. Registration was MJF262 - WOF in 2020 cited 63,942km. Sad how that car only lasted 2 years here. WOF on the windscreen was from 2021...

Gave the spare exhaust a quick lazy polish before bolting it up and dropping the car off at the shop. Even on the way there I still hadn't fully decided on the final course of action - whether to cut out the resonator or the secondary cats. Sound wise both would probably have had the same effect but the smelliness of it all was my main concern. Had the guys at the shop start up a couple of decatted cars to get a sense of what life would be like cat-free. Don't know if I got an objective feel for it or if my sense of smell had simply been decimated from sniffing all the brake cleaner fumes over the years but it didn't feel as bad as I had feared so cat delete it was. Somehow turned out to be a bit more work than I thought it would be, they cut out a bigger section than I'd envisaged but the end result looked really nice, the welds were tidy and the sound exactly what I was after. This was a progress photo they'd sent through, I forgot to ask for a full underside photo at the end. I'll be taking the exhaust off shortly to fit new exhaust gaskets, refit the damper at the back of the resonator and finish off the polishing mission so will take a photo of the rear section then. Loving the end result, the purr at startup is awesome, has a nice deeper tone to it throughout with a tinge of the signature BMW rasp. Loud enough to be enjoyable but not loud enough to be obnoxious so shouldn't annoy the neighbours too much. Once warmed up it's still surprisingly quiet at idle but definitely feel a bit more kick when giving it some beans. Took it onto the motorway to see if there's any droning but all good on that front too. The smell isn't nearly as bad as I'd feared as well, probably would only ever be an issue if left idling inside the garage for a while. VIDEO: Cold Start VIDEO: dB Meter Test VIDEO: Before Comparison with the 325i Exhaust Took it out for a quick bash along the hills the other weekend with @Carbon and his Honda mates, as well as a certain infamous M5. The muffler-deleted V8 and well as my newly opened up exhaust reverberating off the surrounding hills was a bloody nice soundtrack. Have now clocked up a couple hundred km's on the new exhaust setup and couldn't be happier, a nice finishing touch. Quickly running out of things to improve on this car. Thanks again to @Gaz for the hookup. Wifey called me a bogan as I pulled up into the driveway so that's the mission well and truly accomplished.

Got a little bit more work done recently, been busy making a plan for all the suspension stuff and figuring out which direction to go for the clutch/flywheel. Decided to keep it oem and stick with a dual mass flywheel and oem 240mm luk clutch kit. Got all the underside parts taken apart and sandblasted, in the process of getting painted at the moment. gearbox is back from kayne Barrie now with fresh detents. More or less just need to order the clutch kit now and then can put the engine and gearbox into the car. picked up a e90 325i auto front half driveshaft and a e36 medium case rear half from @Toast which so far seem to work together, will see if they end up the right length. Paid $80 for the front half instead of the $700 people charge for zf 5 Speed Front halves nowadays. will need to swap the carrier bearing over to an e30 one as well. Fuel pump is back in the car too now ready to start replacing subframe, trailing arm bushings etc now and reassembling the rear end.

Got back to tinkering on this little nugget this past weekend. Since it was still misfiring, I decided to do a compression test to make sure the issue isn't with any of the valves getting jammed. Shockingly, the result was 225-230 PSI on all cylinders. I was a bit taken aback by such high numbers. I then noticed that I had disconnected the valvetronic motor and the eccentric shaft sensor plugs when removing the coils. Wasn't sure if it'd influence the results I reconnected them and redid the test, this time around getting 175-185 PSI on all cylinders. That ruled out compression being the issue. I then moved onto the smoke tester to check for vacuum leaks. Having removed the airbox and throttle body to insert the smoke tester adapter, I discovered a major f**kup, which turned out to be the cause of the backfiring - a vacuum hose from the EVAP valve was left dangling loose, unconnected from the intake manifold. It took a fair bit of force for it to clip in properly, not sure if I had missed it completely or hadn't seated it properly when reinstalling the intake. The throttle body and airbox obscure it pretty well so would have been easy to overlook but silly mistake on my part none the less. I went ahead and did a smoke test anyway, which didn't reveal anything obvious. I then took off the valve cover and rechecked the timing - all perfectly in time still. Got everything reassembled last night and did a quick test start this morning before running off for work - she now idles buttery smooth. Then took her for a quick test run after work - far from a pleasant driving experience as things stand, but at least she's back up and running! The tyres are barely holding air, the brakes are garbage, the steering is vague, the shifter sloppy and the AC compressor will likely grenade itself as soon as I press the button but felt a nice sense of achievement clocking up some 10km along some backroads for the first time in years. Will need a fair bit of love to be put back on the road but hopefully this means she's not destined for the scrapyard just yet. Happy days. It'll definitely need new tyres, and probably the rotors machined at the very least to pass but will book her in for a WoF to see what all she needs to be made roadworthy before throwing any money at it. Hopefully it's nothing major. I'm growing quite fond of this quirky little thing.

No they were gone too.

Currently got this setup with the BMWP bumpstops on my car and would recommend highly, they are definitely a bit stiffer than stock (relative to other e87 I've driven) but nothing too crazy. 100% a good OE-ish replacement for NZ roads!

Yesterday I got the tires fitted to the ARC-8's and today I put them on the car and went for a test drive. It will surprise no one that this setup is a huge improvement over 19s with old RE050A's. The first few minutes of driving were weird, it felt like I'd lost a bunch of road sensation and it took a few minutes to realize it was just harshness and unhelpful noise that was missing. All the useful feel of the car and the road through the seat and wheel was still there, it was just a quieter smoother ride with much less of the unnecessary hum, buzz, fizz, whatever you want to call it. As soon as I realised I could still read the road as before I settled in and started comparing the difference. I can't talk to how the Potenza Sports compare to the PS4Ss, but compared to old RE050A's they are very significantly quieter, I first noticed this by noticing that the CSL intake sounded louder! 18inch wheels are clearly what this car was designed for and are better than 19s in every way when it comes to ride quality and feel. I'm very happy I opted for the firmer sidewall of the Potenza's over the, softer than PS4S, PS5's. The accuracy and immediacy of handling is still there, significantly improved upon with new sticky tires. I need to give a big shout out to Bry5on for his advice to put 9in wheels up front with the ET42 offset. I'd always been worried about putting anything too wide up front, afraid of ending up with heavy, dull steering, but with pretty much the correct offset and lighter wheels and tires all the precision and immediacy is still there, and when you get on to windy open road the feel of the car with a larger tread patch up front and closer to square setup overall is just superb. On the topic of weight. The combination of lighter wheels and lighter tires means I'm almost 4kg lighter per corner, which (including weight of the rotors) is close to a 14% reduction in rotating mass, and I can really notice the difference. I'm always skeptical of my butt-dyno because I'm always concerned it is excessively influenced by the "wallet factor". But in this case there is no doubt. Acceleration and braking both noticeably benefit, not to mention how much better the car ride and holds to the road with less unsprung mass. In summary, as you would expect, this is a fantastic upgrade in every way. I do want to thank everyone who took their time to give me advice and suggestions on this project. It wasn't one I was planning to do right now, and as a result I had not performed my usual excessive amount of research and preparation well in advance. I'm very grateful to everyone who shared their knowledge and experience to help me arrive at the ideal outcome. Thank you! Like heinzboehmer I've very much missed driving the car while it's been laid up, so like him when I got it back on the road a short test drive turned into a longer one. Only I ended up at a slightly less globally-famous landmark. The Mt Rex sand processing facility in Helensville 😂 Also, it's winter here, it was raining, and the sun was in the wrong place.
