Default New RS-T in DC-Metro

Last night at 10:30 p.m me and my buddy finished the turbo set-up using factory WRX parts. The total amount of time spent was after work from wednesday to sunday. Pics below.






Ok here is the problem, Driving normally everthing is ok. As soon as you start going for it like over 4thousand RPM it bogs down, Feels stock. The apexi A/F joint on the turbo timer start blinking out of range. (Am I running rich?) Does anybody have some setting for the apexi safc that I could try?

P.S. also using a greddy profec E-O1 boost controler set to 4.5psi and cutout at 5psi.

I think you need to explain how your fueling is set up and what type of engine management you have before you can get a straight answer.

I agree with 8complex.

So how much boost did your boost gauge say you were pushing? Since you said you were using factory wrx parts, if i remember correctly, the wrx turbo wastegate is set to about 8 psi? You can't really set the boost setting on the boost controller lower than the wastegate setting.

Are you running a stock RS exhaust??

We had a local RS-T owner who ran a stock RS exhaust for awhile and he was running into the exact problem you are describing. It went away after he installed a 3" turbo back exhaust.

Just thinking out loud.

Are you running the stock WRX intake under your RS manifold?!? How did you get it to fit if so?

8complex - Still running factory RS fuel pump, lines and injectors. I have been thinking that it might be a fuel cut. *tomorow I will have wrx fuel pump lines and injectors hopefully that will fix the problem. Also, as far as engine management it's the stock RS ECU Apexi SAFC and Greddy ProFec E-01. the car drives great no idling problems just the engine light which I believe is do to me burning the RS o2 sensor in the WRX exhaust manifold.

CrayZee - The boost controller has peaked out all the way to 5.0psi. and spiked to about 5.5

Marcus - Am I running a stock RS exhaust? no Actually its no exhaust. The down pipe goes to the wrx mid pipe and that's it. That will also be fixed tomorow with a Turbo XS rear section.

OKRS25 - No its not a WRX stock intake. I forced a silicone pipe in there. Does anyone know of an intake that would fit on the RS that's not cramped up under the manifold. Any designs that have worked thus far? (I wish I could just relocate the power steering)

Cool, the WRX setup is getting more popular. I was able to use a home depot 90 bend on the turbo versus under the intake manifold. I'll be using an actual 90 turbo hose to, but this works fine for now. You'll have to use spacers where the uppipe meets the exhaust manifold to push the turbo back about 1-2", or at least that's what I did, so it doesn't but up against the intake manifold.

Of course, just get a pump and a resivour off a WRX and you should be good to go. You may need to get some hardware to connect the lines, too, but I haven't taken a good look at it.

Are you running a voltage clamp or does the safc deal with that so you wouldnt need one?

8complex - Yeah it's worth giving a shot! Thanks.

boysetsfire - Not running a voltage clamp. Never heard of the need to use one.

rhdude - I'll most def. come out and check it out.

4wheelmotion - oil drain, no problems there, looking good so far. no, no problems when under boost. About the fuel pump I know, I'm installing a WRX one today. My car has always ran ritch ever since I purchased it, I thaught putting the turbo on would have leaned it out a bit but no, it's still running rich
