i just got confused about wg..need a little help
i was reading in the forums, as usual, and got confused, im almost completely done collecting parts for my diy turbo kit and up until now have not heard/seen anything about lengthing the wg arm on an internal wg to lower pressure....im going to be using a 2g eclipse t25 on a d16z6 want to run 6-7 psi safely ive gotten all the fuel management down right now but this threw me for a loop, what do i need to do? and how do i do it?
thanks for any help in advance

Theres been tons of posts about how to lower boost on an internal wastegate 
. But anyway, you'll want to cut the wastegate rod in half, and thread both ends of the rod. Go to home depot or someplace like that and pick up a long threaded nut to match the threads on your wastegate arm. I can't describe how this nut looks but it's longer in shape than your average nut.
Then you will be able to lengthen the rod by threading the nut in or out depending on where you want your PSI set at. I thought there was a topic about making your own adjustable wg arm in the "new user's FAQ" in this section of HMT.

yea i looked there and there is a link for it but it doesnt work 
once i get everything together would i just have to take it for a run and then come back and adjust the psi according to whats seen on the boost gauge during the run?

Pretty much. If your unsure what your wastegate is set at, you can use a bicycle pump or some sort of pressur applying pump with a guage on it to see what PSI it opens at. Or you can lengthen your actuator rod quite a bit so the wastegate opens early, and bring it for a drive to adjust it from that point. Keep an eye on your guages though.

ive seen very little about the spring, but i havent looked that hard either, but i was talking to my dad about it and he had a pretty good idea that i wanted to run by you guys and see what you think...what he said was why couldnt i unbolt the wastegate actuator from the turbo and throw a couple of washers behind it and bolt it back on effectiveley pushing the whole thing forward which would be the same, i think, as lengthing the arm, while keeping it stock so that when i get the injectors, etc i want i can just put it back...what do you guys think, it would certainly be easier and put me at a better peace of mind..
