M30 OEM Turbo project

Shit, did I tell you one goes to ground instead of 12v and the other to the ECU?
Sorry if I confused you.

IIRC you said one wire to 12V, one to the ECU. Is that not correct? Should it be one to GND and one to the ECU?

[ak-]

There are only 2 wires to connect. One goes to a switched 12V source, the other to the COM port on the back of the ECU. Easy!

Ya, it's back on page 30-something IIRC

Have you gone to a front mount intercooler?

beautiful man. my favorite turbo build. nothing comes close.

all balanced? how were the parts marked?

You can see the red paint on the compressor wheel. I have some more photos of the complete, assembled unit with all the balancing marks, but photobucket is being a little bitch right now and I can't seem to upload them.

Interestingly, they applied ceramic coating to the exhaust housing even though I'd already had that done. So now there's two layers of coating on the housing, plus a turbo blanket. If this doesn't keep down the underhood temps, nothing will! Add in the coating on the CHRA, the new heatshields, exhaust coating, and exhaust wrap, and this thing should be as insulated as humanly possible :up:

Some more turbo photos

that is seriously sweet looking. built to last.

I just received some photos from the guys at G=Pop shop of the turbo, it's looking great!

New billet compressor wheel. 53mm inducer, 78mm exducer.


Attached to the turbine shaft:




And the CHRA, now ceramic-coated

My EBC setup arrived from DIYAutoTune yesterday. The setup is super easy. Since I still don't have the Tial adapter, I'm going to have to put the stock WG back on for now, hence the single-port configuration:


The kit comes with 1/8" barbed fittings, but my lines are 3/16", so I had to get a couple of new fittings


All installed, along with a plug for the unused port.


And mounted on the old airbag sensor bracket in a vibration-resistant clamp.

Subscribed, lots of good info here to help with my M30 turbo build. Kudo's! :coolphoto:

Sadly no, so far all I've come up with is that CAD drawing that shows the dimensions of the OEM valve and mounting plate. The tricky parts to figure out are 1) can any of the aftermarket WGs be separated, i.e. remove the elbow from the spring/diaphragm/valve assembly? and 2) How long is the valve stem and what is it's movement range from open to closed? Machining an adapter isn't too hard, but the other part involves me buying a $350 WG and then proceeding to tear it apart and possibly destroy it...

Just buy something like this and save a few bucks.

I have a 44mm that just laying around for parts but will be to big for your application

I bet I could put together an adapter for you. I do have access to lots of equipment (4k watt laser, CNC mills, etc...). Got pics of an adapter someone else has made?
