M30 OEM Turbo project

[CorvallisBMW]

Me too! lol. My wife is getting annoyed with my constant repetition of, "I really need to work on the car today..."

Not much. I ran some wires in the engine bay and wrapped them up with friction tape, but I forgot to take pics. Most of the weekend was spent on other things :/

ah :/ i wanna hear this thing make turbo noises!

I know you did something over the weekend....

That's some serious amps... What's the 40A fuse driving? Intecooler fan? Or the whole block?

Whole block. So ya, it's a decent amount of power. If all the gauges are running, lights are on, fan is on, wideband is active, and I hit the sprayer button... that's a lot of current. I'd rather be safe than sorry.

No kidding. I'm getting better/more comfortable with it, but it's still not my favorite thing to do. The hardest part is keeping it all looking halfway decent and not like a giant rat's nest of shit.

I'm realizing that the 30A fuse that powers this new fuse block isn't nearly big enough. Time to upgrade to a 40A. All the wire is already 10ga so it should handle the extra current just fine.

So much wiring. Makes my head hurt

[CorvallisBMW]

Did some wiring things yesterday. These 2 switches will control the 10" fan mounted to the intercooler as well as the 2nd washer pump that acts as a sprayer for the intercooler. Since my iX washer reservoir already had space for a 2nd pump, I thought 'why the hell not?'. I'll be running a 50/50 mix of water/alcohol in the tank which should help keep down the heat soak in such a tiny IC.

Switches installed. The fan switch is a normal on/off, and the sprayer switch is a momentary (spring loaded; it only stays on as long as you have it pressed).


They run of these relays that are hidden behind the OBC in the dash



Initially I didn't think I was going to need all 6 slots in the new fuse block, but I was wrong!



I also started wiring up the LC2 wideband and George Graves display

and an AFR..

I have the George Graves AFR gauge all ready to go, just need to wire it in with the LC2 wideband.

Really coming along nicely!

I'd like to get it to the exhaust shop by the end of the month. I still really need a boost gauge...

Yea I'm gonna go with the podi vent gauge setup for my car. Have all 4 gauges on one screen
