another flawless job done by the good doctor! looks good!!! (guess im the next patient!!!)

it should just be, from the turbo to the IN and from the WG to the out. then cap the 2nd port on the wg. your dip switches should be 4321= up down up down

but, something is really wrong with your car if you are only getting 4psi. stock boost is 10psi and low boost is 7psi and thats only if the ecu detects a problem and wants to put you in low boost mode. if you are only getting 4psi, then you have some type of problem that should be addressed before you put a boost controller on.

Hi Lagos,
I just had my swap done, I'm boosting btn 6-8psi and no more than that, I still have my GT exhaust on. If stock boost is 10psi, could my problem be restrictive exhaust of something else? thanks Eli

6-8psi is called "low boost mode". the ecu can put the car there if there is some type of problem. i could be anything from bad gas, a boost leak, a cel light or something else. the exhaust could do it, depending on how small it was and if your cats were cloged up really bad. but to give you an example, i had a really crappy midpipe that got damaged. the thing was maybe 2in in diamiter and the rest of the exhaust was only 2.3in and i still hit 10-11psi without any boost controller. so, getting 6-8psi isint right.

zips. the car has two things that get confused a lot. there is tvis, the system that opens up the extra intake runners on the manifold and there is the tvsv, a factory selenoid boost controler that makes the car boost around 10psi when the ecu decides its safe to do so. when installing a boost controler you have to disable tvsv.

yea, my 2nd port on the WG was capped and thats when i was only getting 4psi... dont i want tvis to work still?! or am i missing somethings. if i cap the 2nd port, i also cap the other side going to the tvis?

It has nothing to do with TVIS, that's a different system. You need to cap one of the nipples on the wastegate, then run the other one to the control motor, and the other side of the control motor to the compressor nipple.

And yeah, if you're only hitting 4 psi then you've got something wrong.

Are you loosing coolant, like do you have to fill it up every couple of days to keep it full?

-Doc

so what do i do with the 3nd nipple (1 comp housing, 2 on the WG. and the 3 is where the 2nd WG port connects to) ive added about a little more than a quart of water the other day. i havent had a heating issue sense...

[lagos]

between the turbo and the WG is where you install the ebc. from the WG to the tvsv, you disconnect that and cap the 2 nipples with vac caps.

you are loosing coolant, overheating and have a loss of power. those are normally signs of a blown head gasket. do that compression test before you do anything else with the car.

[brianforster]

what nipple did you guys use to run your boost controller line into the cabin?

[lagos]

any vac line from the intake manifold. just dont use the fpr vac line, like greddy recomends.

art, i posted above this is exactly how i had it run. this is when it was stuck at 4 psi and the controller did not work. my heating issue is too sparatic to be a HG, and there is deff not a loss for power here. but your right on the compression test. i do need to check it just so i know

if you are only getting 4psi, then you have major loss of power. you just dont realize it because, even at 4psi, the 3sgte is a big upgrade from the 7afe your used to

i am not at 4psi. it was stuck at 4 psi and will go back to this state if i cap the 2nd port on my WG and cap the other line that it connects to.... i understand totally from my 7a to the 3s. but i also understand my 4psi and 10psi that its at now.. i am confident that there are no major problems with my motor, again i still agree to do a comp test and i will find someone local to help me check it. and if it is the headgasket ill be relieved to know its not something even more major.. if which i doubt, but if it is the HG, i can only imagine how much stronger it will feel if i have to replace it...

DR. tweak, how are you setting up the vac lines whenyou installed them? dip settings,and where is our gain set?

[malecrod]

Well well well, I had my new exhaust done today by HPR customs. it is a 2.5" mandrel bend pipe, magnaflow hi-flow cat and magnaflow muffler and over the axle. I originally wanted the 3" but the installer said there will be problem with clearance going over the axle, so...well. I'm happy to say that my boost gauge did read a tad over 9psi when I took it for a drive. Overall I'm very happy with the exhaust work except for the extra decibels from the magnaflow muffler. Now I'm thinking silencer? Maybe time will tell, I may get used to it.

i have a theory why some people get a magnaflow and think its quiet, while others get one and think its too loud.

when you look at your exhaust, does the tip stick out past the bumper a good bit, or is it flush with the bumper? if its flush, youll hear it more in the car, but if it sticks out past it then you wont hear it as much. at least thats my theory. let me know how yours is.

Yes it is flushed with the bumper with a 4" tip and it has a deep tone to it. I don't know which model or # it is but I will try to snap pic later.

[lagos]

thats why its so loud then. instead of trying a silencer, try to have your exhaust guy move the muffler back a little so that the tip sticks out past the bumper. if the muffler tip is flush with the bumper, the sound will just resonate throught the whole car, making it much louder and more annoying.

i have a full 3in exhaust from the turbo back, with no cats or resonators and my magnaflow is fairly quiet and not at all annoying.

[laff09]

the 2nd port on the WG is connected to the TVIS line also

you have to disconnect the 2nd port on the WG and cap it off when connecting any type of boost controller. if you dont, it wont work correctly.

Not to hijack....curious as to what exactly this TVIS plate is, where its found, and what it does

[laff09]

nm, question was answered above

Well Lagos, I just had a hi flow resonator put in today and boy, what a big difference in sound! Now the car is as quiet as stock be but with a very deep note..., just a beautiful note. I guess the resonator was the answer in my case. The only drawback was the boost takes a little reving than before to reach its max, but thats a small price to pay considering all the noise a vibrations above 65mph.
Anyway, just want to let you guys know in case someone else is having similar issue. By the way, my exhause pipe is 2.5", so a 3" or more may not neccessary have the same issues.
Thanks
Eli
