Ok it's about time for that WGA exchange I've been asking about..
Tell me if I have this right?
the stock MSP boost is controlled by the stock WGA set at 6 psi if functioning correctly. From what I understand the Forge WGA is set around 8 psi.
So would upgrading my WGA which I have to do anyway also be upping the boost to 8 psi? So in turn increase my HP?

yes. you will be running 2psi more boost which means more power. Not much with an otherwise stock setup, but a little bit more then stock.

or do the "spring mod" for like 4 bucks and an extra 2 psi.

there is also another WGA sold by ATP Turbo for around 60.....i think Rush is using one......i think is the same used in the SR20DET

The WGA upgrade isn't for the PSI, it's do to the a WGA giving me issues, causing fuel cut. The added 2 PSI of boost is merely a bonus!!
its a pain to replace the wga too...be warned haha
I dont know if you have to set the arm to a certain length or not I just winged it

The good thing is that I have a bumper to bumper warranty that this is covered under. Usually I do most of my car work myself, but I figured I'd take advantage of the warranty, and do the WGA, My oil leak, and motor mounts all at the same time in the same ticket. Also I can have the work done at PG which means they will cover whatever parts PG carries, So I get to upgrade on the warranty dollar!! Forge WGA, AWR mm, and what ever the oil leak needs.
damn you... I wish pg was in calgary...*sigh*

The Forge WGA can be had in whatever psi you desire, 5-24. Mine is supposedly stock boost, I haven't been able to drive the car much to know for sure. Also they reccomend the compressor housing or IC piping be tapped for the vac/psi source...
how can you change the psi rating on a wga? through the length of the actuator arm? and how do we know what to set it at for each applicable psi level?

forge offers the option to set it up with a spring for the rating you're going for.

thats right the Forge WGA gives you access to the actuator spring....so you can change it to fit your desired psi
so its the spring its nothing to do with teh adjustible actuator arm?

I've never heard anything about changing actuator arm length. i guess changing the length would change the leverage against the spring, but doesn't seem to me that would be a practical way to adjust boost level.
I do all the adjusting electronically I was just wondering I guess if it should be at a certain length, I dont think so considering im still driving and maintaining steady levels meh
but anyways to answer zuku, the answers are yes and yes (technically)

Great!!! Does anyone know what the spring rate that comes with it is? I thought I read somewhere 8 PSI but I can't confirm that. Ideally It would be set at 8 or 9 PSI, and I won't have to deal with a boost controller, I don't plan on doing forged internals or anything, so I know 10 PSI is walking the line of danger!! So keep it at 8 swap all the external shit out, and I'm making power baby!!

You can order whatever pressure you want stock or anywhere from 5-24psi...

Are you saying that I have to order a pressure?? there has to be a spring already installed on the WGA out of the wrapper off the shelf right?? what is the pressure that is comes with without ordering a upgraded spring?
found this at forge webpage:
This actuator is designed for the Mazda Speed Protege.
Manufactured from Billet aluminium, this Forge adjustable actuator is a two part assembly that will allow servicing and mainteinance. It also allows for rod adjustment to suit the customers individual application. This product is built with a predetermined actuator spring suitable for at or slightly above factory boost levels. The actuator can be assembled with a stiffer spring upon request. Please contact us directly concerning this process.

if I remember correctly, the standard setting for the forge is 8 psi. (im at work on a crappy low bandwidth connection or I'd go check) but I think it mentions it on corksports site.

Upon driving my car mine only does about 5.5 psi...

I also heard the ATP does anywhere between 8-10psi, it's like random or something. Can someone confirm this?

the ATP is actually setup for 6psi. i have never seen one hit 10psi with just the actuator alone. truth of the matter is this - wastegate springs with recommended settings are pretty much just that, recommended settings. we installed an external Tial on a protege with a 9lb spring that only got the car to 5lbs. every setup is going to react differently, plus the various components you have in the turbo system will affect the boost. you may have a small boost leak, an intercooler core with pressure loss, etc. nice thing about adjustable actuators is being able to compensate somewhat by adjusting the nut/rod.
heck even stock msps hit different boost levels. i have seen from 4 to 9 psi stock to stock on msps with no more mods than a boost gauge.

i would have asked how you knew what the boost level was w/ no mods, but since you covered that base, instead I'll ask where the heck you are finding stock MSPs... cuz clearly there are some owners that need to be informed of what they're missing out on!

We offer four springs:
Green - 5-10
Yellow - 9-14
Blue - 14-18
Red - 19-24
You adjust throughout those ranges by way of the threaded turnbuckle on the end of the actuator rod.

Does adjusting on the turnbuckle at all contribute to boost creep or anything negative?
Also I'm extremely satisifed with my WGA thus far, and kick ass turn around time! FL to WI within 2 days of ordering! Thanks!

If you adjust to low (not enough preload) you can hurt response and potentially get some creep if there isn't enough tension to hold the flap shut against exhaust gas at high RPM.

what type of spring do i need to push 9 ibs of boost without a boost controler on a forge wga

Green would be the way to go with a fair amount of pre-load or yellow right at the light end of its adjustment.

newb question. I just ordered a Forge wga with "9lb" spring. if 'when' this gets installed and i test out to only 6lbs. will this be able to be adjusted easily with it still installed? or does it have to come out completely to adjust it? thanks.

You'll need to tighten the turnbuckle if that happens. You should be able to perform this on the car, if i recall correctly, just disconnect the turnbuckle from the wastegate flapper and shorten the rod.
