I just checked to see if you could use an EMP/Stewart water pump, unfortunately it says it fits m50/52/54, but only s50/52.  I have one and it is very high quality.

I had one in my 330...great unit. 80k miles and it looked brand new. Luckily the OEM components on the M3 hold up pretty good unlike the non-M E46s.

First time I've been able to really tax the cooling system since I've done all of the upgrade...or decontenting. Right now, I've got an OE cooling system. The goal is to provide enough cooling that will keep temps in check (260 oil, 220 water) during a 20 minute HPDE session. The only upgrades are:

1. Deleted the aux and mech fan
2. Installed a SPAL fan controlled by the OE aux fan controller
3. Oil diverter valve
4. A/C deleted
5. 100% distilled water with 1/2 bottle of water wetter

Ambient temp was in the mid 80s and the humidity was atrocious. The OE oil gauge stayed right at 255 and the OE water gauge never went above the 2/3 dot. I forgot to monitor water temps in the OE cluster but I was at 180f at the end of my cool down lap. Pretty happy but I think I am still going to install a 25 row Setrab cooler mounted in front of the OE radiator. Then I will just replace the radiator and water pump (maybe) with an OE part. With the A/C out...I don't see much of a need to replace the radiator for an HPDE application.

BRAKE DUCTS

The seemed to work pretty well. I ran stoptech street pads instead of my usual SR34 race pads. The street pads did OK. They will usually overheat and then just have zero bite and generally suck. Last night I think the ducts kept the pads cool enough so they had a consistent feel throughout the night. No "OH S$@!!" moments!

Here's a video from last night at the Milwaukee Mile...really liking the Evolve tune! Finally it feels like it has a little power! I do need to replace my front tie rods...the are seized and won't adjust. My alignment, in general, is shiet. I have to look at my UUC DSSR...3rd and 4th is tricky to get into gear. I might have it backwards (not upside down). I think I can easily break 1:18 with an alignment and clean shifting.

So I got some hose and flanges...

I've had the BW backing plates on...I think they are about $100.

So I basically routed the hoses like everyone else does. The wheel is an Apex ARC8 18x9.5 et 22 wheel and clears the hose at full lock. I got dual outlets on the ducts so I'm using the driver's side as a cold air intake, not sure what I'm going to do with the extra one on the pass side.

So I basically zip tied the flange to the bumper opening. Ghetto? Maybe. Show car quality? Nope. Does it work? We'll see. Then I filled in the gaps with aluminum tape. I do want to plastic weld ABS into the gaps but this bumper is trashed so I'm just going to wait until replace the cover. I wouldn't do this to a DD but, IMO, fine for a track car. No need to spend $300 on a CF duct. $40 works fine.

Here's the cold air intake

And some ricing...I meant racing stripes.

Ask C.young about our first experience. #completehelltrip

The amount of times I've dropped the diff in my E28. I know this feeling all to well. I got my diff swaps down to an hour and a half though. By myself. That was pretty fun.

Nice!

Nope, the only aluminum is the upper control arms. The diff was pretty heavy but doable with one person. Just need some finesse and got repertoire of curse words.

Is all of the rear suspension/subframe aluminum?

The E30 subframe with diff and axles was quite the heavy monster to install without helpers.
