Sidenote, I picked up my gouged radiator from my old place today and realized I had some fan mounts still on there. Hoping they will fit my new setup.

Re: STC Hunter B18C Stock Block DC2 Street/Track Build
It's too bad your WG flange is oriented like that. On mine they angled it towards the block, so the dump tube goes between the block and the downpipe keeping clearance for the radiator. I don't have any pics showing the dump tube but you get the idea.

Re: STC Hunter B18C Stock Block DC2 Street/Track Build
I was able to weave the dump tube towards the t-casing. I'm at a crossroads - I could either just pretty much run more tube straight down and be done, or I can try to recirculate it. I really want to do a recirculated dump tube. I'm including a picture below with a red circle showing where I want to route back into the down pipe.
I'm running the dump pipe like 1/2inch close alongside the down pipe. From my understanding, I want to angle the dump pipe as parallel to the down pipe as possible(like 15-30 degree angle connection), and not run it perpendicular (90 degree)?

Open dump results in faster boost recovery, and fewer issues with turbulence. Reber, you don't hear it, until you reach tester boost pressure when the gate has to vent. Otherwise, it's as though it was closed anyway.

More like 15*. And you want that further down along the downpipe before transitioning into it, not at the bend of the downpipe.

Re: STC Hunter B18C Stock Block DC2 Street/Track Build
So basically before my flex pipe is the most optimal spot? The only reason I want to do a recirculated dump is to hear that sweet turbo whistle instead of basically a giant exhaust leak when its open. I might just forego the recirculated dump this time and go with the open dump, seems like its over my head at this point. Could you explain boost recovery a bit? Quick google search didnt do me any good.
Google search fails when it comes to turbochargers..

Re: STC Hunter B18C Stock Block DC2 Street/Track Build
Open dumps are nice for performance reasons but I think I will go back to a recirc for the reason you mentioned above. Its generally all you can hear once the thing gets going lol

Open dumps are for VW and the rest european cars. We have an engine that likes you to know its there.
Hondas sound great on recirc wg setup or full savage uppipe.
Im thinking of getting very silence on the exhaust side(cops...) and weld a china 60mm wastegete on the start/first elbow of the downpipe after the turbo.
You can even make it "uppipe" with the safeness of noone droping rocks into your turbo.
Make it to open only close to full boost for the times you like to make some noise, plus it will relieve the exhaust from gasses too lowering after turbo backpressure.
These 60mm wastegates flow very very big numbers.
I know its ricey AS FUARK but who cares. Men growing up is just an illusion.

Anyways, you guys are making me want to recirc it... god I can't decide.. I guess you'll see today what I end up going with. I'm thinking I should have everything welded in the next day or 2 so I can send my down pipe, dump pipe and manifold to my friend to get ceramic coated. I ordered a bunch of parts last night - mostly new intercooler couplers and t bolt clamps. My couplers had residue in them and a couple clamps are rusted shut. I decided on this K&N air filter (RU-5111). Any input on my filter choice?
Also I was looking up plugs last night and what I should be running. Right now I know I have Iridiums but no clue what heat range or model. From my research people are using the NGK BKR7E-11's? I'd like to use Iridium over coppers though. While were on this sort of topic I guess I'll state that I'm using Castrol Edge 5w30 full sythnetic. Also what are you guys running for tranny fluid??

Re: STC Hunter B18C Stock Block DC2 Street/Track Build
Wouldn't that cause major turbulence having both those wastegates right next to the turbo??

As for the plugs. Use the coppers until you complete the tuning, then switch to the iridiums. You can always cross-reference the copper, with its iridium equivalent from NGK/Denso. But you have the right part number to start off with.
Transmission fluid is determined by what components are in the transmission, so there's not a "favorite" or "best".
OEM transmissions with OEM components and OEM LSDs love OEM MTF, or GM Syncromesh
Some Aftermarket Helical LSDs use Torco MTF to start off, then possibly OEM MTF
Aftermarket clutch-type LSDs can use Kaaz GRade level 5, Gear X, or Motul 90PA w/ a Redline friction modifyer

Re: STC Hunter B18C Stock Block DC2 Street/Track Build
You're overcomplicating things. You have to experience it first before you can even tell yourself that re-circulation is the route you plan to go. You have the right length for an open dump right now. Just try it out after tuning. You can always recirculate it later, like I did. (Which then made me go back to open dump.. Much easier to deal with)

I almost have the dump completely welded up, but I ran out of gas yesterday and the gf was demanding a date night. I think she's getting jealous of the teg
Found a nice simple setup for ya

Re: STC Hunter B18C Stock Block DC2 Street/Track Build
I finished welding things together today. The dump pipe turned out pretty ugly.. It was hard to get a straight line on that 1.5" tubing. The down pipe turned out much better, probably because I did it last. My welding skills really improved over the course of this project. Some of the areas I improved in most - using the right settings in the right situation, and technique, in which I learned how to get a much better weld on flanges.
Look at the difference in the welds!

Re: STC Hunter B18C Stock Block DC2 Street/Track Build
Anoter idea could be a tiny wg silencer/muffler
It will not be silenced but it will make different noise

Re: STC Hunter B18C Stock Block DC2 Street/Track Build
I've run into a few small issues. There are 3 vacuum hoses to my boost control solenoid - 1 goes to the top of the wastegate, one goes to the side of the wastegate and one (used to) go to the compressor of the turbo. I don't have a fitting on this turbo for a vacuum line, does that mean I will have to pull vacuum from the intake manifold for that hose?
Another small issue that I've had for awhile and never figured out, my boost gauge rests at -10psi. It didn't always do this. I replaced the dash awhile back and ever since it has read -10psi of what it should actually read out. I've checked connections and tubing, but to no avail. Any idea why it's doing this?
I made some quick little brackets to mount the fan with.
I got a text from my powdercoating guy a few days ago that the parts are finished being cerakoted. I'll pick them up tomorrow I think and then reassembly should start.

Re: STC Hunter B18C Stock Block DC2 Street/Track Build
Honestly if it's just a mechanical boost gauge, looks like it's broken =\
I would definitely take the 3rd vac line from the intake manifold for the boost controller, not from the compressor housing.
Looks like some good progress being made

My powdercoating buddy is the MAN. Check these out.
I put in the elbow grease but he did a really good job powdercoating them. Metallic charcoal. Freshest set of blades ever.
