quick general turbo questions
I was wondering about a few things, maybe you guys can help me out here.
oil drain : what is some of the easiest ways to do this?
from what i've read you have to drain the oil into an unpressurized location.
external wastegate dumptube : which would be better running the dumptube from the wastegate into the downpipe for the turbo or just having the wastegate dump into the atmosphere with say a 24 inch downpipe.
wastegate springs : I know what "bar" means but in relations to what does the w/g spring have to do with? so I want to boost 10 psi into the engine what spring would the w/g need?

the easiest return for oil is normally tapping high in in the oil pan...
dumptubes are easier to make and prevent power loss causing turbulence downstream of the turbo..hinders flow and loses power...just go atmosphere...
for the wastegate, what do you plan to run for a boost controller? if you want 10psi I would run a lighter spring and use a boost controller as you have room to play and turn down boost incase of a bad tank of gas...
1 bar is 14.5 psi incase you were asking...

alright i'll run the oil drain high on the oil pan
use a long dump tube and dump it into the atmosphere
plan on running 10psi after the tune. so with what you said about the spring for the w/g should I run a 5psi or a 7psi spring and then conrol it with the ebc?

what wastegate are you running?...guessing tial or turbosmart 38mm...?
they have them ranging from 3.5'ish psi on up...so run the smallest one and use a boost controller for any level of boost over that

I agree, go with the 3psi spring, itll leave you room to go down if your fuel cant handle 5-7 and will give you the ability to fine tune.
Oil return can be in the oil pan, just make sure its above the full oil level or else it will cause draining problems.
Alot of people swear by the block return, but i dont like the idea of drilling a hole in my block, although this way makes leaking improbable even without weld.
Unless you plan on running a huge amount of boost, you wont see any losses in turbulence in routing the wastegate gasses. The extra amount of noise with a wastegate dump isnt the most appealing sound & may not be your cup of tea, and it may get some "unwanted attention"
