try to open and close the wastegate by hand, if you can open it relatively easily, you need a new actuator

how much boost is it making?
It's Gumby's fault.

is the waste gate actuator working properly? the new turbo you put on was it a new or used one? did ya plumb the vac line to the waste gate the right way?


the turbo I put on was used but I couldnt move the wastegate by hand. its barely making 5psi but if I bypass the hoses on the I/C  I can make almost 10psi  wastegate was already hooked up when I got the turbo.  what is the little round box on the fender with the two wires and two vacuum lines? and what does it do? could it be bad?

thats the boost control selenoid, they usually dont go bad

try taking the vacume lines off of the selenoid, and connecting them together, and see what happens with your boost, should be 15psi or so

I have tried what you suggested and I get about 10-15 psi.  I just got a boost controller from ebay.  is that where I need to install it?

basically, where it says to put a plug, i just put caps over the fittings, and it works just as well, thats how i have mine routed

if you need pictures or anything, let me know, and i can pull the IC off and show you how mine is done

alright, the pics didnt come out as well as i had hoped, especially since i kept burning my knuckles on the turbo, but heres what i got


yes, i know its large, but i left it that way so things could be clearly seen

the split fitting i just capped off, you could use a pipe plug for it, which i believe its a 3/8's pipe thread, you can get em at most auto parts stores, similar to the one that i have on my inlet

on the inlet, if you kept all of your cruise control vacume lines, one of those tall fittings will have a line that goes to your intercooler, leave that one on, but cap the other off


in this shot, you can see where my boost controller is tucked, right next to my turbo inlet hose, youll see a little bit a brass poking out, i would have free'd it up to show you how the lines are run more clearly, but i kept burning my knuckles like before

basically, you take a line directly from the vacume tree on the firewall, and run it directly to the bottom nipple of the boost controller, the one directly across from the adjustment screw, and then the other nipple on the boost controller gets run directly to the wastegate

if you need anything else, let me know, ill help ya out

thank you for the pictures, I think I have an idea of how to hook up my boost controller.  I unplugged my O2 sensor and it seems to be running alot better. I dont know why this would be.    but back to the boost controller...  cap everything on the turbo and I/C?  and run from the vacuum tree on the firewall. sorry if I sound stupid I dont really understand how this works.

the line that runs from the turbo inlet to the a/c is for your cruise control, leave that one hooked up

cap off the rest

on the vac tree, there should be one nipple with a cap on it, uncap it and run that to your controller

got ya, I'll be doing this tomorrow.  also I think maybe my cam timing might be off a hair.  gonna check that too.  I think that might be why I am not accelerating like it should I'll let you know what I find.

Re: smoke.....

well, I got everything hooked up and it is boosting 15+ but I think my cam timing is way off because I have no power what so ever and it sounds as if its backfiring throught the exhaust.  are there any tips or tricks when setting cam timing on the 2.3?  I seem to have no luck :dunno:

Re: smoke.....

do a compression test, backfiring through the exhaust could be cam timing, or a blown headgasket

a compression test is a bit easier than messing with cam timing

ive run mine as high as 21psi without too much issue, didnt go any faster with the IHI, but it was up there

too much boost wouldnt cause that problem

its starting to boost at maybe 1200 rpm's  and thats showing a full 16psi on my stock guage  kind of acts like if trying to force too much air into it too soon.  I'm gonna play around witht he controller today and see what happens. turn it all the way down and start from there like I should of done in the first place.... :crazy:
