Thread of some of the progress: (1) 377Z’s V70R | SwedeSpeed – Volvo Performance Forum
I’m pretty tame and think of the car as stock, though I guess it isn’t strictly speaking, list of what I can think of below. If I missed anything its in the above thread.
EDIT 12/13/2024: updated text to current, still need to update photos
Changes:
Delrin front subframe mounts
polyurethane front LCA bushings
IPD front and rear sway bars
Bilstein B6 front, Jag rear shocks (inductors from OE shocks plugged in, no ‘chassis settings service required’ light), car is on stock springs (not lowered)
Home Depot engine bar washer mod
Painted stock pegs in ‘mock diamond cut’ (one is mildly curbed)
Momo shift nob (I was not a fan of the stock one, but I still have it)
Fog lights are amber LED cubes (stock were gone when I got the car)
New in the last year:
Continental timing belt, OE water pump, and serpentine belt
Front and rear pads and rotors (OE/pagid)
Last year the clutch release and shifting felt funny; was clear something was wrong with the clutch so I took it apart. Found that a piece of the friction material broke off one side (??? Odd as I don’t do launches or powershifts). Due to the HOA where I was staying, I opted to pull the motor/trans, put the car back down on its wheels in the driveway, as I had enough room to work this way in the garage, but the whole car wouldn’t fit in there.
Pulling the motor allowed me to do a bunch of “while you’re in there” work, which includes:
New OE/Luk DM flywheel
New OE/Luk clutch, pressureplate
New OE slave cylinder
All external transmission lip seals (output shaft and axle seals)
Quaife limited slip differential, new diff carrier bearings and races (SKF)
Trans filled with redline 80W-90 synth MT fluid (its what FCP carried)
Stainless 3” Down pipe (did this because the factory DP flex joint cracked)
Middle resonator replaced with a 3” stainless pipe (had extra pipe from the above, stock rear exhaust pipes and muffler still)
Rebuilt turbo, cleaned up, installed new bearings and seals, changed to 11 blade drop in compressor wheel
Completely rebuilt and resealed angle gear, all new bearings (SKF), filled with Amsoil 80W-90, new collar gear, and used epoxy between AG and collar gear (a la StealthyS60R). Lubed trans side of collar gear and differential splines with 65% molybdenum disulfide grease
New RMS
Full PS flush
New 50/50 Volvo coolant & distilled water
Older repairs—all 5 engine mounts changed, top and bottom are poly, the front, rear, and side are OE. Top poly seems to be coming apart but still drives fine.
The car drives excellent, IMO Bilstein damping is perfect; the IPD bars keep it flat, and the Delrin & poly bushings make the car responsive and precise with no drawbacks. Other than the 11 blade drop in wheel, the engine is completely stock, stock IC, stock tune. Plans were limited to a FMIC and a tune but I never got to that.
Right mirror cover has been painted, I just haven’t updated pics (car is offsite). Have not changed haldex oil/filter or rear diff yet. I had one of the shoulder screws that hold the blue engine covers seize, and the coil cover got mangled before I got it off. Replaced that screw, and decided to get a black cover and paint it since it was basically half the price. Unfortunately I went too light on the shade of blue, but left it as it doesn’t really bother me.
I get an intermittent ‘anti-skid service’ light and check engine due to MAF and O2 sensor codes since putting back together after the clutch job. Not sure if I bumped or pinched something related to chassis code; not sure whats up with the MAF–it might be the battery since the car has been sitting and I’m not sure how good those solar battery tenders work…. Will scan with VIDA/DICE when able (presuming I can get it to run on linux…. )
It has a few door dings that should all come out with PDR, and a few scratches (one on the hood, two by the fuel door, and sides of rear bumper cover). I never bothered to get this stuff fixed since I drive my stuff, figured I’d blend those areas myself one day and wasn’t planning on selling, and still may not as I’m not in a hurry nor inclined to move much on price. Reason I listed it is, I got a second V8 XC90 to have a backup vehicle that can seat 6+ and the V70R has just been sitting.
