What did you do for your M3 today?

[eacmen]

Installed GSP SMG brake pedal. Very nice piece.

For some reason I always hate working under there. Can never seem to get a good angle.

Bought it used so the nyloc nut wasn't included. I had one on hand but the sockets I had would not fit between the nut and the brake switch bracket. Even my 1/4 drive 13mm socket would not fit and its super thin. Anyone know of crazy thin sockets? Outherwise i'll either have to find a smaller nyloc or grind down a cheap socket. Right now its pretty tight using open end wrench but not tight enough to my liking.

Big day for my E46 M3:

• Replaced the diff input seal;
• Replaced the Guibo;
• Replaced the driveshaft center bearing; and
• Upgraded to urethane transmission mounts.

I'm going to do the motor mounts tomorrow and subframe reinforcement next weekend--I feel like I'm pushing my luck having a clean subframe w/o reinforcement in 2020.

Retrieved this from my intake port and cleaned it up as well as I could. So far it seems like disaster has been averted.






What had happened was about 3 weeks ago I was attempting to change my starter motor, and the damn dowel pin was giving me a really hard time. One of the things I tried doing was grinding down the dowel pin with a dremel. During that attempt, the grinding stone broke and flew off. Ultimately ended up boring out the hole in the starter motor to get it over the dowel pin. Got things semi assembled and gave the engine a start -- worked, except I had an instant cylinder 5 misfire. What I found was that grinding stone landed right on top of the idle port for cylinder 5 and was blocking all airflow. And in my attempt to retrieve the stone, it lined up such that it fell straight in. And I had to start residency the next day, so I no longer had time to deal with it. So I cried a bit, borrowed my mom's car to go back to my apartment and get to/from work, and left the M3 parked. Got my first weekend off this week, peaked in with a bore scope, found I lucked out and the valve was closed, and improvised a solution to retrieve the stone. Cleaned up the intake port of dust as best as I could and blew it out with compressed air for good measure (this time covering up anywhere else that shit can go).

So far car seems to drive okay. I am concerned that some of that aluminum oxide dust may have ended up scoring the cylinder wall when I first started the engine before I realized what had happened... but so far seems to be okay.

Compression or leakdown on cyl 5 might be good idea just for peace of mind.

Finally got a hold of a Euro200R. (Got rid of the euro sec 1 last week)

Car was "slightly" overheating at the track (110+ ambient - yes some of us got bored of sitting at home and went out in the middle of the desert in the middle of summer, no mech/electric fans, aux in place). Started hearing some chirping/squeaking from the front of the engine, so replaced (via FCP) the water pump, tstat, idler/tensioner and cleaned out the radiator and oil cooler fins (water blast in opposite direction of normal airflow, followed by therapeutic session of jeweler's screwdriver and picking out tiny lodged rocks).

ordered some new track pads to replace one that exploded on my on track.

and also upgraded my DME to a CSL firmware and already the idle feels far better with the IAT/MAP sensors enabled. no more idle hunt from an alpha n tune.

Are you running the Kassel MAP sensor adapter? That's what my Testo screen looked like with the Kassel setup. I moved the sensor (with use of a different adapter) to the brake servo line and that line on Testo flattened out. However, I can't say I felt any difference whatsoever or that it makes any real difference. Kassel claims that once any small amount of throttle is applied that smooths it out.

Installed ducting to let colder air into the rear hole on my Karb. airbox.

Yes, that's what the previous owner had installed. however i just decided to go straight to Epic to get their AlphaN tune applied. I'm tired of dealing with people who don't know how to tune the car properly.

= Kassel....unfortunately. Once my SS pipes are on its gonna be Hassan %100.

So those pipes are what? It looks like a US Sec. 1 with resonators downstream of some tiny cats. Cool setup, just have never heard of a Euro200R and am not quite sure what it is.

[Tbonem3]

Yes, made by Jack @ CPI years ago before he sold to BW. Wanna say the piping is slightly over stock as well (like 2.25 or even 2.36 instead of 2.16").

That's a huge step down in terms of the quality of cat, mind. More flow, however.

Leatherique over three days outside in 100+ heat during July 4th break. Re-applied generously twice in the back and 3x in front and steering wheel. Car then sat for 2 weeks (in garage). What a difference! Even the Mrs gave compliments 😏

[M3Bob]

Cleaning of the throttle bodies and replacement of both TPS. after 200K they were pretty gummed up.....
