Nidhg00670000 posted:Early magnesium wheels had lots of problems with corrosion, which is one reason why they went away. Modern magnesium alloys don't have the same problems, supposedly. Mg alloys are up to 1/3 lighter than aluminium alloys but have lower strength in general. IIRC VW has been using Mg in their gearboxes of late, for example, where demands on temperature resistance and strength aren't as high.

The sequential box in Ken Block's cossie was magnesium. It was a real bitch to put out. I assume a lot of race boxes are also mag.

My quick googling shows Magnesium being approx 34% lighter than Aluminum per volume. That's more than I would have thought.

Yeah, but you might need more magnesium by volume to hit a strength target. So unless the original design for the aluminum part wasn't properly optimized for weight savings, that's a best-case weight savings.

I was at a random guy's backyard shop having a turbo rebuilt around 2001. He was the turbo guru of the area, Tom at Euro Car Tuning (which later became ECS Tuning) referred me to him. It was a typical old man's backyard machine shop, except he had a lot of specialty equipment, obviously more than a hobby. We were bullshitting and he pointed to something off to the side. It was a Chevy 350 (pre-LS days) made of magnesium. He had some story about prototyping it, but what I remember was that I could lift it up with one arm. I wish I had pictures.

If I had gently caress you money, I would be machining 13B/20B/26B plates and housings out of magnesium and swapping them in every 911 I could get my hands on. Because a turbo rear engine car isn't exciting enough, it also needs to be in constant danger of combusting into white hot flames simply from idling. Edit: Still want a 997.1 with a dead engine from IMS failure to swap a turbo 13B into.

Not the same materials (or brands) as being discussed, but as an example of this I can mention the Mopar 340 I switched from some ancient Crane Cams design of alu roller rockers to brand new steel Comp Cam roller rockers, and out of curiosity I measured them. Turns out a steel rocker arm was actually a couple of grams lighter than an aluminium one, probably because of suboptimal design.

Dave Inc. posted:The 3.0 and 3.2 have more or less the same issues with only a couple of failure points, none catastrophic, but all costly. Well the 3.0 has poor chain tensioners but those can be replaced for about $1k. I don't know a lot about the 2.7 other than that the magnesium block can fail, which is not great and a reason why lots try to stay away from them or you find later 3.0s in 73-77 models. For the 3.0 and 3.2 they'll all eventually need a rebuild for head stud failure, but that's a one time thing. General maintenance, though, is a god-damned breeze. Easiest car to take care of for regular things that I've ever owned*. Thanks for the awesome effortpost. Sounds like really, anything that's well maintained from the 80s would be a decent place to start, and the G50 vs 915 isn't really a huge deal. I guess I'm having a tough time trying to get a sense of the market, since I see 80s air-cooled cars selling anywhere between 30k and 80k on Bring a Trailer, and it's tough for a newcomer to figure out what percent of a final price is the car versus maintenance versus something like rarity. And with respect to maintenance, is it really that easy? There are a lot of independent Porsche aircooled shops within easy driving distance of me, but it seems like half of the listings I see have "$10-20k in receipts from the last year!"

I really, really, really liked this - https://www.autotrader.com/cars-for-sale/vehicledetails.xhtml?listingId=546709082&LNX=PSEMAILLEAD Only way it could be better was if it was a Targa and/or S trim. Color is perfect. One owner, always dealer maintained, all records. I offered him 33 which he said he thought was reasonable, but he was waiting for another offer to finalize. That offer vaporized so we started talking again. I told him I could send the money today, schedule a pickup, and it'd be easy as possible - I just wanted to do due diligence with a PPI 20 minutes away, which I would pay for. He was a real jerk about everything, said the PPI was too inconvenient, claimed he had another offer, said he would stop talking to me right there, etc. Jesus, are all 911 owners like this? I noticed the dealer maintenance records are full of him complaining about the horn not being loud enough, so maybe that's reflective of who I'm dealing with.

It was more inconvenient than the buyer coming to my house, giving me cash, and driving away. But it wasn't that inconvenient. The PPI showed nothing that wasn't already disclosed, the buyer gave me cash and drove away. If the seller of the 911 pushes back that hard, there's something he doesn't want discovered.

I was trying to buy a 2009 C4S PDK launch edition in San Diego in Feb, and the owner was difficult, dragged his feet on ppi or sending pics, all the same stuff. I finally used carfax garage to find where he'd had it serviced and called them about the car; where I heard the words 'bent tie rod' and 'worn front CV joints' for the first time. I think that car has a big problem and the owner knows it.

When my wife was still thinking about a Cayman we had a couple done then turned the results over to the owner for future sales. poo poo, when I bought my SC the guy let me borrow it overnight to drive it in to Dallas for a PPI since he was 1.5 hours away and didn't have the time.

Your normal maintenance is fairly simple, yes, so long as you're comfortable getting the car in the air yourself. Those big bills are only going to be for things like head stud failures on the SC or top-end rebuilds on the 3.2. It's definitely worth finding out if those have been done already since they will happen, just a matter of when. Looking at my own maintenance log I've spent $20k in seven years of ownership on required maintenance, $8.7k on upgrades and $4.8k on optional maintenance (things that didn't need to be done but I wanted it nicer or heavy duty track use). $13k of that was from an engine rebuild for a head stud failure, new 1st and 2nd gear synchros and all new clutch, pressure plate and assorted hardware. So if the rebuild had been done prior to me buying it and I weren't using the car on track a few times a year or finding stupid ways to spend money I would have spent less than $10k in 7 years, which is not bad for an old Porsche I think. Oh, and I've put about 25,000 miles on it myself. I'm fixing to spend a good bit more but that's because it's almost 40 years old so the overall paint and seat leather has finally given up. Edit: And it goes without saying that you should do stuff yourself to save money. That overall cost would be about 30% higher had I taken it to shops for everything. I try to limit shop exposure to alignments and diagnoses when I can't figure something out. Dave Inc. fucked around with this message at 13:34 on Apr 16, 2020 |

He may have also rolled the miles back - slightly suspicious that he had snow tires on a car with such low miles. You would think if it was a DD the miles would be higher. Definitely shady regardless if he refused the PPI.

Swapping the steering wheels around isn't too big of a deal, there's Rennlist threads with all the details. It's mostly a question of getting all the parts together with the right options and airbag, and then finding an indy or a dealer without exorbitant prices for a piwis flash. It's not just the wheel, though, the macassar package is a lot of trim bits that you'll have to find, disassemble the doors, etc. And you'll have to think about either putting it back in or holding onto all the bits if you want to sell it later on.

Russian Bear posted:Do targa models command a premium? Yeah, unfortunately $10k+ is not uncommon. They're fairly rare and the only 911 I _really_ want because of AWD + lifting glass hatch to better store stuff in the back seats + open air benefits of cabrio without looking like a turd. Although I just realized the other day that the 997 frunk is the same size as the ND trunk, and I'm down a backseat because of kiddo.

The great recession really did a number on sales. https://www.goodcarbadcar.net/porsche-cayman-sales-figures/ It would be nice to not worry about IMS stuff, but at this point it was as reinforced as it was going to be before they moved away from that design.
