Nice man! The only reason we put "budgets" on our builds is so we can do the same thing to those as we do to the builds - go further than we initially thought. Keep it up!

Noise is the only consideration really. You're dumping under the car so it's not like you could be dumping out at a radiator line, alternator, FMIC pipe, etc... Dumping externally in the configuration you have may get old quick though since it will be open quite a bit at just 6 psi. But, if it is, just make a new dumptube that ties into the exhaust and you're done. Dumping externally will help the efficiency of whatever exhaust you have though, but it's probably a very minimal "gain" power-wise.

Or get a small muffler and dump it through it's own pipe! ala Porsche!

Very cool. Putting a muffler on the wastegate dump is a new idea (to me). I wonder how much that actually helps.
For reference, with my current project build i started with an open dump and ended up back at the fabricator for recirculation.

When I was on the 16g-frame turbo, the open dump got pretty annoying. With the 30R, it's nowhere near as frequent/annoying. It also sounds a lot more "angry" now pushing out 27 psi from a 30R, lol.

Crazy
No mean to laugh but lol at trusting myself @27psi on a street tune. I dont expect that to happen..... ever.
OP. Like i said on page one.... expect to be over budget... @your <10psi goal, a dump tube will be annoying.

Not sure why you gave me the face 
Thanks for sharing. I love a clean E30.
I asked Napalm to change it a couple days ago. SC gonna be #1 next year just wait.
I like the new name, it's a double entendre. I have a slow 4Runner, and I love to run but I'm slow.
I posted my goals on the first page, but to restate I'm hoping for around 250hp and 300ft/tq to the crank or 215/255 to the wheels assuming 15% loss. I think the turbo will be able to hit peak torque before 3000rpm.
At some point in the future after a Walbro 255lph pump and a URD 7th injector kit I think 300whp is within reason for the stock bottom end and will be no problem for the turbo.

Of course I intend to keep offroading. It has been done before  The turbo is tucked up pretty high by the rear axle so it is fairly safe. I wont hit the trails until I have a full belly skid on there but it will be just fine. Only issue is deep water crossings which I have started to avoidto protect seals, diffs,and wheel bearings.

Of the oil lines? Turbo will be going on this coming weekend, so nothing to see there. I'll post picks of the lines this evening and will mock them up to make sure everything is the right length.

Heh, sorry your last post above mine I thought implied you'd basically gotten everything done were just waiting to slap on the turboz.
I'm pretty curious how this turns out, on accounta I might be "inheriting" my brother's '95 4runner, and something like this would be a pretty fun project.

To give you an idea of their size:
-10 Return from turbo to pump is 9ft long
-10 from pump to oil cap is 5ft
-4 oil supply to turbo is 9ft.
I talked to the guy that makes commercial lines and he taught me all about JIC fittings. I never knew what they were so it was really cool to learn that AN fittings are overkill for most auto applications and JIC is a less expensive but reliable substitute. I saved 100 dollars using JIC on my hoses rather than AN and they will screw right on to my AN oil supply and return fittings on the turbo.
The scavenge pump is mounted on the top of the pass. side wheel well in the engine bay. The oil return will be a straight shot down the passenger side to the turbo. The feed supply is on the driver's side and will run along the driver's side frame rail and turn near the axle to the turbo.
I also mounted the boost gauge and wide band gauge last night but had problems with the boost/vac gauge getting a vac reading so I didn't wire everything up. Going to try a different vacuum line when I get home to see if I can get a vac reading.

I always tee my boost gauge into my FPR line and haven't had a problem.

Ahhh, gotcha. I'm spoiled, my FPR line is right out in the open (as is most of the stuff in a DSM come to think of it).

Hah... that does bring up a thought - do you have any way to increase fuel pressure with boost, or is it one of those deals that with the stock tune it runs so friggin rich that 7 psi actually brings it to a reasonable AFR?

Here is what TRD says from the Supercharger manual regarding the need for increased fuel pressure:
"No. After extensive testing, TRD has learned that the fuel system
has sufficient capacity to deliver the additional fuel to match the
additional air induced by the supercharger.
Most folks with forced induction have found this to be true. Of course you must run colder plugs and only premium fuel, but most people have been reliable for a long time around 7psi.

All oil fittings and lines hooked up and run with the exception of the supply line which is run but not connected. Only thing left before running charge pipes is to weld the turbo flange pipe to the stock exhaust.
Oil return
Turbowerx pump and drain lines.
I didn't take pics of the lines underneath but will in the future.
