Duffy's 1/71 Series 1 240z build

I live in the middle of nowhere / paradise:)

3/8 NPT is in. Next is pcv. The 3/8 was stressful 

[duffymahoney]

Well ITB with IAC and PCV is all in and plumbed. Only thing left is 2 wires and some software changes. Pretty happy with how it all turned out. 

[duffymahoney]

Fully wired. I was able to use the coil wiring and leave original wires intact for my dpo negative trigger and positive.

Well this bosch and all bosch IACs of this style let a ton of air by when closed.  Bosch said roughly 30-35%.  Which makes the butterflys useless at idle.  My next iac will be a ford.  Which closes all the way and only lets a tiny bit of air by.

E31 is back from final surfacing! Vapor blasting it was tedious. But results are awesome. 

[wheee!]

Mines a Volkswagen version. Probably gonna have the same issue...
Was yours a three wire? Mine has a pull down resistor to ground to keep it closed.

Well the 80s bmw iac is awesome, smaller and nice looking. Let’s no air or minimal amount by when physically closed Now to find out what pin is positive.

If there are just two connections and it's a simple spring loaded solenoid valve inside, it really shouldn't matter which pin is which. It should operate the same regardless. But if there's anything else in there (like even a protection diode), polarization would matter.

PCV question. This isn’t a debate about the need for a PCV vs a catch can. I want true postive vent. I decided I want to use my exhaust to pull the fumes out, to keep the dirty fumes out of my intake. But since I have Fujitsubo. I have true dual exhaust. Is plumbing to one good enough? Should I still use the stock check valve? I would guess it holds back a tiny bit of pressure before popping open?

My plan was to weld this bung at a 45 just past my o2 bungs on my exhaust. With the stock check valve in line.

Now this looks snazzy.

Rebuilding my stock oil pump. Really it looks brand new inside. It was the original and still had overspray on it!

Oil pump is in. Looks nice!  Such high end casting
