Original 1st Post
Purpose: Go through the experience of building my perfect E28 daily driver, from the ground-up. When complete, the car will be a refined, sporty, daily driver that will provide shit-eating grins while driving and will induce lustful look-backs when parked. The level of restoration and refurbishment will justify the zero-mile odometer in the instrument cluster. The journey will be more important than the destination; some things will be done simply for the experience of doing them. Every part will be either new or restored to like-new condition. I will be doing almost all work on the car myself; the exceptions being things that require craftsman-level-skills to do right, such as paint and body work. I'm open to (even eager for) other's ideas, suggestions, and input, but this car is for me.
Budget: I budget ~$15k/year for cars for me (not including insurance or fuel). This covers ALL of my personal cars (but not my wife's or kid's) and thus will not all be spent on this build. I expect this build to take 3 years total (clock started ticking last summer when I bought the chassis). I do not plan on keeping a ledger on spending, just generally keeping within my $15k/year budget. I'm sure I'll end up spending more than rationally makes sense.
Completion Goal: I like having a date-based forcing function to drive a project, so I'm using 5erWest 2019 [Edit: original plan was 2017] as the goal for completion.
The starting point for this project is an Arctisblau on Pacific 1985 BMW 528i (Euro) with a 5/85 Build-date. The car was originally an automatic, but converted to a 5-speed at some point. This car was once in @alpinass' hands and I bought it from @cooperman. As is typical, Kohler knows more about the history of this car than anyone.
The car has been resprayed (poorly) and while completely rust-free requires all new paint to meet my standards. None of the original interior pieces have survived and thus I have a nice blank canvas for the cockpit. The chassis came with a ton of new and good parts, some of which had already been installed. For example, the front suspension is all new with 750 upper thrust arms, tie rods, center drag link and idler arm, and new Lemforder aluminum lower control arms. All of these will come off first, though. It came with a brand new OE windshield, brake lines, heater core, and more. Interestingly, while the BMW build sheet indicates ABS, the car did not have ABS on it when I got it (and didn't have it when @cooperman got it either).
For completeness, here's the BMW build info:
Until now, other than cleaning the chassis I've not done any actual wrenching on this project. I've spent a lot of time (and money) collecting thoughts and parts though. I now have almost everything required to finish the car in-hand, hence the creation of this thread.
Below are my current plans, on a sub-system by sub-system basis. I'm sure many of these details will change as I make progress, but they represent my current vision for the project:
- Color: Porsche Minerva Blue. Update (mid-2018): I changed my mind. Now Porsche Arrow Blue which is the same tint as Minerva but without metallic.
- Painted euro bumpers & mirrors.
- Shadowline trim.
- M5 front spoiler. Black.
- No rear spoiler (or maybe something customer and super subtle like that found on the E39 M5).
- Tinted windows. Update (mid-2018): Starting with a set of OE bronze glass.
- Glass moon-roof.
- Entire chassis (including under-carriage) will be stripped bare and re-finished.
- S54B32 from a 2005 M3 Coupe (25k miles) controlled by the original MSS54HP DME re-programed to delete EWS and work optimally on an E28. Update (mid-2018): I was convinced I needed to update the rod bearings even though the engine is 'young'. The cost of that led me to just saying eff-it and going 'all in'. Motor has been rebuilt by Steve Dinan and is now his 3.3L Street Engine Rebuild.
