Just got my precision turbo back from repair and putting it back together, I torqued the oil feed hose a little too much and broke the adapter. Using my digital caliper, I got these measurements:
15/32 male (goes into engine)
11/32 female (onto hose)
I was able to match the 11/32 side to a 3/8" #24 screw. But I have nothing that can match the engine side. Looks to be 1/2" but not sure the thread type.
Want to order the right thing the first time.
I was told by other riders that I'd always put out a small bit of smoke after idling. Other than that, no issues. I know it's another thing to maintain, but think about the hundred of things I'm already maintaining in a way that could go wrong as well lol. If that was the mentality, we'd all be riding around on unicycles. 
I can easily wire in a relay off the fuel pump to power the scavenge pump. I only got 10k miles off this turbo, that's doesn't seem all that great. If a pump would make it last longer, it would pay for itself.
Speedway has been closed since covid sadly. But yea, that is the only one left on LI.
I'm out east in Manorville.
Easy Off Oven Cleaner
Would I need to bake it with that on? That's how ovens work with that stuff I believe.
Nevermind, just read the bottle and it says do not bake. Let me try that.
Yes it does! Looks like there's one cerakote place on LI. Left them a msg to see how much they want to spray this thing. Hope it's not too much.
Vinegar/Soda combo got the rust off, but what's left is this baked on black stuff. Wouldn't come off with my wire brush. Tried carb cleaner and no go.
Anyone know what I can use to get this off? I don't have a sand blaster. I do have a dremel, but was hoping a chemical solvent would be easier first.
That would have been awesome! I'm on Long Island.
Thanks for the info. I'll have to use some elbow great and try to find a place that can do the cerakote around here.
Has this happened to anyone else's supposed "Stainless Steel" exhaust header? Shouldn't this never happen, or does the high heat somehow affect it's rust-free properties?
I took it off When I sent the turbo in for repair and wondering what I should do with it to restore it.
This is how my drain and feed are situated. I cut the hose shorter when I originally installed it, so it always has a decline and only slightly level in the middle.
MACAWS The front oil pan return is situated higher than where I have it? Would that really be required to eliminate the smoke? I figured the pump and a check valve would eliminate the backing up entirely.
rabtech, I've been running an Alpha Turbo kit for years and I'm now getting constant exhaust smoke. I noticed the turbo is leaking oil as well now. Just removed it and sent it to Precision to get it repaired.
Before I found this thread, I was already looking at installing a scavenge pump as I figured it was a drain issue that finally took my turbo oil seals out. It's helpful you posted pics of the pump location you used as I was wondering where I could mount it. So thanks for that.
Question I have is do you have any pics to show how you ran the hoses? And just that pump in between turbo drain and the pan return was all you needed?
Got the SCG-1 installed finally. Now I just have to get it configured properly.
Is there any info on how to do this out there?
I only found to set the RPM to 0.5. I also set shift RPM to 6500.
I had no oil in for about 3 weeks during my install, didn't prime or disconnect my fuel or anything, and she started right up first try. Later my friend told me I should have disconnected fuel and allowed some oil to pump into the turbo for the first time, but it was too late by then. So in my case, everything worked fine w/o needing to do anything special.
I'm gathering we just have to stick that sensor somewhere it doesn't rattle around too much. Not in the spot the 2-bar one goes.
BKL, now that you mention it, I wonder if anyone has tried tapping into the wires from the 2-bar sensor and sending them to the gauge. I don't see why that isn't possible unless the ECM gets bugged out somehow.
There would be no need to put a T in the vacuum line then.
Thank you everyone, great info here! That's what I like to see.
I just installed my turbo, and already bought the studs. I also have a digital torque wrench and breaker bar, so set on the tools.
I'll give it a good cleaning before lifting the cover as well, good idea with using air. My SS only has ~1500 miles so I doubt I won't be able to reuse my gasket.
What's involved with pulling the cam cover to replace these? Do I have to drain anything, or just disconnect what's up top, undo the bolts and lift and bolts are right there?
Putting the cover back I don't have to play with any RTV right, just the gasket and make sure it's clean?
Yes sir. From what I gathered it can't be used as a controller in the SS with the MEFI ECM.
I messaged Innovative, but there only response was:
"It would have made much more sense to purchase a PSB-1 if you do not need the boost control function. That said, if you install the boost controller and simply skip the installation of the solenoid, it will still read boost and AFR."
But I still have to hook up the controller because the gauge itself doesn't have a vacuum tube. So the above doesn't help me all that much. Do I even use the 4 bar map sensor? If so, where?
Hi rabtech, might I suggest installing the tapatalk plugin so users on phones can navigate that way? I run it on all my sites and prefer its navigation over built-in support.

Could use some help on installing this gauge with the Alpha turbo, any info out there at all?
