Hey all - first post, first time bmw owner, first time caller. Just picked up this 1991 318is locally. Purchased from original owner, a nice lady, who did all ~197k miles, for $1300. In order to test drive it I had to find and repair a leaking fuel line just before the fuel filter :)
For the last decade I've been solidly in the Japanese realm, other current cars are a 2005 Sti and a 91 mx5, both thoroughly gone over. In the past I've had six other mx5's, a mint FD RX-7, Mazdaspeed6, Wrx wagon, and an Mr2 Turbo.
This car is tired. Properly tired. The original owner did a commendable job keeping up with oil changes, air filters, plugs, and the other standard maintenance items, and everything on the car works, for the most part. It's just worn out, with sloppy steering, shifter components (stirring pudding), pedals, and brakes.
The paint is faded to a dull pinkish hue (hence my newly chosen username). There's very little rust, just a bit in the battery tray, a tiny spot on the floorpan underneath below and behind the rear seat indent by the fuel filter, and standard surface/edge corrosion of some subframe/support parts. The driver side fender, bumper, and the hood were repainted back in the early 90s, and those panels are doing what early 90's resprays do - peeling their clearcoat and pitting badly.
It's an interesting options package - in that it has almost none, including the omission of a number of features that all 'is' designated models seem to have.
For example:
- no sunroof, where nearly all do (hand crank for 318is)
- cloth interior (sport buckets, though)
- no foglights
- no LSD!!
The diff in particular was odd, I'd seen it repeated often that all 'is' models had an LSD. I found the diff "tag" utterly corroded and illegible. After hitting it with a wire brush, file, wire wheel, and finally sandpaper, like the world's most recalcitrant lottery ticket, I got a loser. "4.10 063". Not "S4.10 063", so it's an open diff. I'll get the wheels up in the air to spin them and make sure, but I seem to be out of luck.
The steering is vague, with the four spoke steering wheel listing right 15 degrees or so. The boots are leaking like crazy. The brakes are alarmingly mushy and slow to react. The transmission doesn't grind, but every part of the shifter linkage, from the knob on down, is shot. Reverse is no fun to get into. On lift off decel, the car dives, so I'm guessing the motor mounts, trans mounts, and likely the diff mounts are done.
The motor cranks and starts up well, sounds healthy, and pulls fine. I'll do a compression test on it, but it seems to be in good shape. That's helpful for my long term plans.
So wat do. As I said, everything has to go. But I've done projects where the car goes offline for months or years at a time, to do *everything*, while things are already apart and accessible. I don't want to do that here - I've driven it less than 50 miles in two sessions, and those miles were sometimes arse puckering with the steering and brakes. No bond yet formed, though I can see the potential. Likewise with no solid long term plans, jobs even so imperative as the shifter rebuild could need to be redone if I follow the engine swap route, which I almost certainly will once the M42 is dead/ on its way out. As sad as I am to discover an open diff, even the reasonable $300 cost of swapping in an LSD may be a waste of money if an S50 swap demanded one of the bigger diffs to work reliably.
So for now - get it back on the road with:
- proper steering (rebuild/install e36 3.2 turn rack) Happened on an e36 rack for $40 shipped with good tie rods/ends, otherwise would have splurged on an m3 or z3 rack.
- rebuild shifter (combo of ebay shifters, stock replacement parts, and poly bushings, in progress)
- replace ODO gears.
Then drive for a bit while collecting brake bits. Some of the lines are corroded, I'll replace those, along with new rotors and mid range, decent pads (like PBR or something) and flush with ATE Blue. Brake upgrades may tie in with a 5 lug swap, so I'll wait until the suspension phase is complete to consider bigger brake options.
Drive a bit while collecting suspension/chassis upgrades. This will be the big one - I'll need control arms, 4 or 5 lug, all arm bushings, (likely offset poly), subframe poly, Bilstein sports with yet to be determined springs, poly shock mounts, sways, etc etc. I can weld, so I'll be adding all the reinforcement plates that are on the market, and likely making some of my own.
Next, engine cooling, with an eye towards preparing for a motor swap, and also prolonging its necessity. Fit a bigger, all aluminum radiator, new tstat, water pump, and any lines that are aging badly.
Then would come the interior rehab - also a big deal to me. Pretty much nothing in there now can stay. The dash will have to go, though with the only uncracked examples I can find going for over $500, I may try to recover the stock one with new leather. I have minty black vinyl front sport seats sitting in basement storage, with a black vinyl rear bench/back on the way. I'll need black/vinl rear side panels in good nick, and due to the price of good front vinyl/leather front door cards I'll probably make my own blanks from ABS, with custom pulls. I did this for my '91 mx5 and they came out fantastic (pics later). The headliner will be recovered DIY style, did this on my '05 sti without needing stitching, but in this case I may have my wife try her hand at recreating the OEM pattern.
Then the exterior, where I think the paint on all panels apart from the hood, front bumper, and driver fender can be restored with my Porter Cable and lots of work. The repainted panels I'm not sure about yet. I'll either need replacement panels from parted out brilliantrots whose paint can be salvaged, or to gamble on a professional respray of those panels that may or may not match well. I do have all the gear needed to HVLP spray, but haven't done it yet. I've painted a bunch of small body add ons for my Subaru, and a fender for my mx5 using paintscratch.com cans (base, clear) with outstanding results, but a hood, fender, and bumper would require many cans and is a much bigger job, in a higher stress area (road debris, chipping)
The lower rockers and bottom of the rear bumper I'll respray with SEM Trim Black rattle cans, which is awesome stuff. Dries to an even matte black finish that is very durable.
Finally it would be time to consider drivetrain swaps. S50/S52 are the most appealing to me right now, but it's almost too soon to think about. There is, as I said, a lot to do. Adding power is not yet near to the top of that list.
The dichotomy between the BMW and similar vintage japanese cars that I've purchased is between the sophistication and logevity, easily. Richard Hammond put it well - Japanese engineering tends towards "just enough" - but not necessarily in a shoddy sort of way. The materials and mechanisms on their cars aren't as complex, and this doesn't mean that they are shoddy or cheap - it means that everything is distilled to what it needs to be, and no more. That does mean that they tend to last. For example, were you to buy a 1991 mx5 with 200k and a non enthusiast ownership history, you'll be rebuilding the shifting mechanism just as surely as this e30's. But the action in the mx5 won't be nearly as far gone, and will require around ten bushings, washers, and rubber pieces to rebuild, all done from the cabin. I've never seen anyone consider rebuilding mx5 pedals/assemblies, and doubt their would be an appreciable difference if you did. That's not to say that when both cars had zero miles, that there were not stark differences in fit, finish, and feel. And that's why I've bought one - I love a lightweight (2600lbs stock, soon to be less), no nonsense, rwd car. But at 36 years old, I'd like one with a touch more refinement and comfort than say, a '91 240 notch back that's laid out in similar fashion.
So this is my project. Here's some moar pics, and I'll be diving right in with the shifter rebuild. Resist the urge to say TLDR. I'm talky, but there will be useful info posted, I reckon. Starting with what I've only seen alluded to, which is combining ebay SSK's into something a little better.
