Obioban's 2005 IR/IR Coupe

[Slideways]

Doing a little spring project on the M3, which is fun-- with building the house, the e60 M5, etc, haven't really had time to do anything with it for a while. Changes:
1) new/updated/lighter/not crumbled under back seat sound deadening pad
2) Bry5on's additional exhaust mount point
3) Higher flow injectors (Bosch 0280156063), with new OE BMW injector o-rings and vacuum rail o-rings.
4) one step colder plugs (Denso ixu27)
5) creating a little spacer to allow my OEM (Die Wethje) CSL airbox from before CSL's existed to use the factory CSL air filter (my filter is slightly larger in one corner, so it doesn't get a good seal as is with a factory filter)
6) replacing two of the power steering lines that are slightly weeping
7) installing a wideband so I can use the forum partial throttle auto tuner
8) moving to an HTE tune, to update for my new injectors and colder plugs, as well as tuning the WOT with the wideband/data logger.

All my recent car projects have been e60 and e82. The e46 is so nice and easy in comparison. Really missed it.

Saw this in another thread when checking head studs vs. bolts and was wondering if your S54 had a head gasket failure:

I’ve replaced my head bolts one time in almost 20 years of e46 M3 ownership. It’s unlikely I’ll live long enough to have the reusable arp head bolts be cheaper, at 4X the cost.

Nice. Have you seen the equal length stepped headers for the E60 M5 from Euro Power Sports? He has a video up with stock exhaust and those headers and it sounds just amazing and right.

The evolve long tube headers (made by supersprint) that I have installed are already pretty absurd looking/sounding/power gaining.

Lol fair, where are you going to list it. Its 6spd converted right? I have a client that might be interested in one if you want to tag me when you get it posted or bump this thread.

Yep, it is!

I was thinking M5board, but I don't particularly feel the need to list it at all if he's interested.

Besides the 6mt...

The bad:
~124,000 miles

The good:
clean title
Dinan differential (3.91 IIRC)
Evolve headers
KWV3 suspension
Dinan muffler
always garaged

Upkeep. Lots done at 110,000 mile:
rod bearings (new OE)
main bearings (new OE)
Updated oil squirters from the V3 S85
rear main seal
clutch/pressure plate/throw out bearing/pilot bearing
flywheel
CSB/Guibo
Spark plugs
coils
fuel injectors
all the top end gaskets
Throttle actuators
water pump
thermostat
pre cat 02s
engine mounts
trans mounts
belts/tensioners/idlers
vanos line
throttle actuators
Pre cat 02s

The indifferent:
Black on Black with alu trim
2008

Nah, just waiting for spring. Winter didn't seem like the time to get the best value :P

I thought I saw you selling the E60, did you decide to keep it?

hey man! glad to have found you, good that youre still active.

need some advice, what bump stops should i use for eibach and sachs?

Don't really know, never looked at it. Stock is probably fine-- the eibachs are a pretty reasonable drop.

I'm discovering that the list of NLA parts for M coupe/roadster seems to get bigger and quickly. Problems with low production numbers. I also try to pick up extras of things that seem to be getting harder and harder to find.

[Obioban]

Kind of a boring update, but the old driver door arm rest cracked, so I bought a new one. Feels like the kind of part that will soon be NLA.

[Obioban]

Any update? Can't have the mythical obioban m3 off the road!

Ha, I’ve been driving it.

Pressure tested it and it held pressure. No further coolant has disappeared.

Hopefully it just burped over winter 😜

I hope not.

Zero coolant smell in the cabin.

Going to pressure test the system.

Heater core leaking?
