Wastegate install help

[Jeff240sx]

Ok.  I am not dumb about cars, but this huge wastegate that showed up on my doorstep has stumped me.
It is a tial 35mm wastegate, and nicely polished. Came in a big box, fully padded and individually wrapped screws and plates.
And a one page, the CEO's son drew the picture for, and a man straight from china wrote the instructions for, installation manual.  Errr!
So anyway, there are 2 holes at a 90* angle from eachother and one has the plunger looking thing on it.  So that mates up to the manifold.  The other side has the same flange with the same bolt holes, and no plunger, so I assume its the discharge.
Then there is a hole in the top, and the instructions say "Wastegate air control side port connection supply air from intake manifold before throttle plate."
Plumb a line before the throttle body.. I get that much.  Then the tube splits, and on the high side it has a boost controller, followed by a line with a "vent" and then into the top of the wastgate, with the words "wastegate air control top port connection vent to atmosphere or add air for adjustable boost control."  Why no punctuation?  Anyway... what the hell is that hole for?  Then after the split, but on the low side, the tube just goes into the side of the wastegate.
I guess I'm just looking for some help on how to install this WITHOUT a boostcontroller, as the spring is adjustable.  Which I also don't know how to adjust.  And finally, for the open atmosphere venting of the wastegate discharge, did people put a pipe there, or just leave it open?  
Sincerely,

If you are not going to use a boost controller all you need it to run a hose from the side of the WG to the compressor side of the turbo.....basically after the turbo before the throttle body....do it closer to the compressor.

The top fitting you can leave open.  This basically will let the WG just go off the spring.

yes just run a line from the  compressor side/boosted side of the turbo and connect it to the side port on the WG. as for adjustments, NO. i have a tial 35mm WG and i know it is not adjustable unless u get a different spring(pain inthe ass) or buy a boost controller.

Boosted is right.  W/G are controlled by their spring which can be switched out.  But that spring can also have a tricked signal controlled by a boost controller.  Remember a W/G can only boost as LITTLE as the spring inside.  

If you have a 5 lb spring you cannot boost less than that even with a boost controller.  A boost controller will only trick the W/G in to seeing less boost than the system is producing.

i also heard that ppl rig their blow off valve(yes this is true) so it always stays open, therefore no boost can be made. i have never done this but from what i hear, they do this on purpose for the first 500miles on a rebuilt motor so they dont be a boost addict before the engine gets broken in. but this i know was only done on a supra because he had a 20psi wastegate spring in it. i dont think it will work on the 240sx because of the MAFS. it will flood the cylinders with fuel because it would run rich.

i think this is kinda smart in the eyes of someone who may be a boost addict and cares about his motor, but i also see that this is kinda a pussy move.

as i think about, i know for a fact that this would not work on a 240sx because of the MAFS. hehe
i dunno, ill shut up now because this really does not concern the 240sx

That's strange considering that the Supra has MAF also.....but if that person has a 20 lb spring he was external W/G and a large single...in that case he probibly took out the MAF with a VPC. &nbsp;

I actually just bought a VPC(not available in the US yet) also to remove the MAF sensor on my SR when it is installed in two weeks. &nbsp;Stupid beater car is turning out to be more of a project than I wanted it to be.

But looking forward to it.

Ok. I am searching for a spring. Apparently mine is .45bar, or 6.6ish psi. I really need a .2 or .3 bar spring, since fuel will be about 2 months away <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sad.gif" border="0" valign="absmiddle" alt=':('>.
Anyway... thanks guys. I really hope the spring swap isn't too hard.

Edit:
Ohh.. yea. &nbsp;Why do I put the line into the side. &nbsp;What does that do? &nbsp;(Just want to know the theory behind things.)
And also. &nbsp;How did you guys make your wastegate open-venting. &nbsp;The flange looks pretty common, so I want to know, did you just leave the discharge hole open, or run a flange and a tube to somewhere else, or did you run it into your downpipe?

Just have a dump tube made from the W/G to under your car....if not you will smell exhaust and pass out while driving.....trust me you WANT a dump tube.
