On the turbo, at the front there
is a round thing that is about the diameter of a soda can and
about 3/4" - 1" thick. That is the wastegate actuator.
It is kind of hard to see until you remove the accordian hose
to the turbo(~3" diameter rubber elbow thing that goes from
the front of the turbo to the AFM housing. The BOV and a few other
smaller hoses hook up to this. Don't forget about the tiny hose
underneath either). Remove the accordian hose and you're almost
there. The wastegate actuator has two bolts that attach it's bracket
to the turbo. Remove those two bolts. It is still attached to
the turbo by a rod that goes under the turbo which attaches to
a lever. If you want to use more than 4 washers, I'd suggest getting
longer bolts. You'll need 8mm x 1.25 pitch bolts. The stock bolts
or 25mm should be good for 4-5 washers. Place the washers between
the wastegate actuator bracket and the turbo for each of the two
bolts(*TIP - put one drop of superglue on each washer to hold
them together. This will keep you from constantly chasing individual
washers that have fallen off while you were trying to put the
bolts back in). You'll have to use two hands because the rod that
goes to that lever under the turbo will give you a little resistance.
Make sure you only pull directly forward(towards the front of
the engine), and don't try to bend it down. Now put it all back
together and you're done! It really is very easy. It took me about
20mins to do and I usually take my time when working on my car.
I wouldn't recommend going over 5 washers without upgrading your
exhaust and intake. 5 washers should put you anywhere from 8psi
to 10psi. An aftermarket boost gauge will be a great help also.
If you have any questions about it, LMK.
