• I'm trying to source a new wastegate for my newly acquired T3.  I've come across this place ( http://www.westcoast-turbo.com/wastegates.html )
  although now i'm unsure as to which one, if any, will work.  the spring ratings both seem a bit low to me, but i'm pretty much a noob when it comes to turbo rebuilding.

• Make a boost controller for under $10 and it won't matter what the spring rate is.

• It looks to me like you'd need to do a whack of plumbing to get either of these two external gates to work.
  
  A couple of other options might be:
  
  1) try to find a T3 wastegate.... these guys appear to carry them:

  2) drive without a wastegate... actually very safe if you haven't dialed up the fuel, and especially if you have a boost gauge.

• so with a boost controller and wastegate, we'd be looking at something like this i'm assuming
  
  
  without the wastegate would the controller just vent to atmosphere?

  heres another I've found, but I am leaning towards no wastegate.  Would I simply plug the hole where the wastegate was or adapt a boost controller into it somehow?

• Rally Diesel,
  
  Would you mind describing the $10.00 boost controller or provide a link to a build post.

• Thanks gnav, just what I was looking for.
  
  Now if I could find a way to source the Lime Green advance spring for the pump I would be even happier.
