Extreme facepalm. I kept on reminding myself that for NPT thread you don't need a washer but I still asked lol
For the WG line, what fitting is required? In my mind, I'm thinking that silicone has enough flexibility to slip onto the barbed fitting but I would imagine that a metal line needs to be all one piece and doesn't just slip on?
Just a heads up, normal NPT is non-interence fit and usually needs dope or tape. NPTF ( f stands for fuel) is interference and should seal without tape or dope. If you can, I would use an NPTF tap. The male thread is identical between the two, but the crest to trough is less in the NPTF female which allows it to seal dry.
If you undo and redo the fitting a bunch, you still might need some sealant to make it seal though.

Yup, that's why the washer isn't needed since you use the sealing tape. The fitting can still be NPT though, right? Just the tap has to be NPTF?
Did some research and found that
. Seems like with NPTF you can't remove and reinstall a lot so it seems like NPT is better in this case.NPTF threads will screw together with NPT threads and should have no noticeable assembly problem. There will most likely be an interference fit between the root and crest on either the major or minor diameter of the thread, depending on which part is NPTF. To accomplish a seal on the joint, a sealant will be required.
NPTF threads are designed to screw together. They are designed to have interference at the roots and crests of the threads on both the major and minor diameters. This interference should cause no assembly problem. The thread deformation caused by the interference fit and the wrench tightening is designed to make a dry mechanical seal.
Because of the gauging requirements of the NPTF Class 1 product thread, sealant should be used to assure a leak-proof connection. Because of the gauging requirements of the NPTF Class 2 product thread, the seal accomplished through mechanical deformation should require no sealant to make a leak-proof joint. This is critical in some applications where the pipe content is corrosive to chemical sealant.

Either will work... if you want use thread tape or whatever
You wont be removing the barb as often as you think. When you change your oil all you have to do is pull the hose off of the barb to drain the pan.
For the Waste gate fittings and turbo fitting your probably using a straight 1/8 npt to -4an barb. Same as your turbo oil feed.
The ends of the hoses will be need a -4an female straight fitting, or whatever your application needs.
I realized that I needed a 90 degree 1/8 npt to -4an barb on my wastegate port
If your using an ebc I would ditch the plastic baebs and replace them with steel as well, same size

That's not my car... lol
Some people run silicone or rubber and it works fine, All depends. I prefer steel, I've read stories about people boost spiking due to loose, damaged, or, melted lines.

I know, I think it's vollosso's which is why I quoted it.
Exactly why I wanted the metal lines lol. Did you run yours just like the picture or yours is full-on metal?

I see. How does it look like on your the boost reference? Are you reading it off of the turbo? I plan to drill a hole in my hot-side IC piping and tap it to get the reference from there
Not that it is the best way, but I used a sandwich style bulkhead fitting from ATP turbo into the coupler out of the compressor housing. Has worked so far and people seem to use them successfully from the research I did.

Get a tune first? How does that work lol. I am gonna attempt at getting a base tune myself. Since I am using a PMAS HPX maf, there is a transfer function tool on their website and I believe I have done the maf scaling correctly. The injectors are a bit more complicated but I do have a spreadsheet for them (Bosch Green Giants 440CC).
By the time I finished my build I was anxious to drive, so I bought one. Was it the best option? Not sure. But I was impatient.
If you plan to purchase one it's best to get a tune first. This way you can you use the tuner as resource as to what and which hardware you should use to reach your goal.
You say you want to tune your car yourself, I suggest that and there's a lot you can learn from it.

A little update for everyone. Still enjoying the car and have had a few guys try to race me.
I haven't lost a roll race yet and so far the car has overcome:
(2) tuned 350z's
1 boosted Mitsubishi
1 90s svt cobra
1 Honda fit
All were beat by a good 1 to 2 car lengths
Car is a blast, still on base tune and hits 14 psi

Honda Fit ????????

Lol
They actually tried me... couple girls being silly. Think they just wanted to hear the open gate

It’s funny to me because I drive one. Maybe if it were turbo K swapped?

Lol, maybe.
I knew someone that had one awhile back, the amount of crap she could fit in was mind boggling. Considering how tiny they are
