M30 OEM Turbo project

[slammin.e28]

I always love OEM clamps. One thing I try to save from parts cars. They just plain work the best.

Nice and tight. Have you tapped into the oil pan for turbo oil return lin?

No, and honestly I may not do it that way. There is a gang blank on the block where the turbo drains on m106 motors. All I would need to do is pull the pan and drill out that gang, and I could run the stock 3"-long rubber tube right in to the block. I think it might be easier and a bit cheaper.

Its coming along nicely!

I'm finally getting a bit closer on the boost controller mock-up. The problem I've been having is how to route the pressure hose from the intake (pre-throttle), through the boost controller, and on to the wastegate. The port I installed on the intake pipe has a 10-24 thread pitch, and the port on the wastegate is m8x1.0. Neither of those are common, and it's impossible to find barbed fittings that will plug straight in. So I've have to spend $50 with McMaster on some crazy expensive little adapters to make it all work. I love them for their selection but hate them for their prices (I also tried Fastenal, Tacoma Screw, MSC, etc but nobody had all the parts I needed)

So it will look like this when done:

intake tube -> threaded 10-24 insert - drilled out 10-24 to 10-32 thread adapter - 10-32 to 3/16" barbed hose fitting -> 3/16" hose -> manual boost controller -> 3/16" hose -> 3/16" barbed hose to 1/8NPT hose fitting -> 1/8NPT to m8x1.0 drilled out thread adapter

Not the easiest route. If I could have bought the OEM tube, I could have cut off the end connections and just ran 3/16" hose everywhere I needed. Probably would have been cheaper too :/

Seriously. It's nice to have a bucket of them sitting around.

I've never parted a car so I don't have a bunch laying around, but I should have a good supply now :) I think I ordered 20 in total.

Had some time last night so I started stripping the old paint off the inter cooler

I also got a replacement rear ashtray to replace the one that's been missing for the better part of 4 years haha



Additional things that were done: adding a bit of clearance to the radiator core support for my air filter. Quick hit with the angle grinder and touch-up paint gave me another 1" or so.

FUCK FUCK FUCK. I was putting the thread adapter for the oil temp sender in to the engine, and this happened:


It broke of clean, with the threads stuck in the head


It's probably because I'm an idiot and threaded the sensor in to the adapter before putting the adapter in to the head. Since the sensor is tapered thread, it probably put extra stress on the adapter and may have caused it to fail. So, what the fuck do I do? I'm stumped. I really, really don't want to pull the head to get it out, but I don't have many other ideas. Maybe a screw extractor?

would be my best guess is a screw extractor. can you get a pair of needle nose on it to spin it loose

[e30austin]

Try JB welding a bolt that's the same size as the inner diameter of the brass part that broke off and see if it'll come out that way?

[kamotors]

you should be able to hammer a LARGE flat head that can wedge in there and turn out.

I've had this happen several times with aircompressor fittings and pliers never worked, but hammering a flat head in there always did the trick.

or if no room-nipple extractor

I've had a nice set of screw extractors on my Amazon wish list for several months now... I guess now is as good a time as any to order them.

Not a bad idea. Hopefully I can find one that's a close fit.

That might also work, if I have enough room. As you know it's tight back there against the firewall with the engine harness in the way.

Yes basically the same as a screw extractor. That will be my first method to try, if it doesn't work I'll go with the JB-welded bolt.
