hose from airpump to LIM
I'm finishing up my install for my A-Spec 3574 kit with short runners, since my county requires me to get emissions done, I need to figure how to run the 2 hoses that ran to the airpump to the LIM/ACV. When I ran a stock motor, I had the Greddy intake kit installed
3 things I am trying to figure out:
1. The main hoses (2 pipes welded together), which ran to the back of the airpump, the other one hooked up to the Greddy intake pipe, where do I install that pipe to?? From what I remember, the top pipe connected to the ACV from the greddy intake and the bottom pipe from the LIM to the air pump, correct me if I am wrong?
2. The airpump has another pipe that points to the front of the car which ran a hose to the [former] intake pipe, where should I connect that to? I followed CrispyRX7's website and unscrewed the pipe and flipped it so it points towards the back of the car, now what??

3. How do I incorporate the single turbo to feed the airpump?

#1. the hose hooked to the air pump is the feed TO the ACV. the other hose is the vent FROM the ACV. under some conditions the fresh air from the air pump is vented to atmosphere before the airpump is turned off.
#2. intake TO the air pump, must be filtered
#3. you need a filtered source of air.... the stock setup just uses a hose from after the air filter.

I ran the air pump output pipe through a hose direcly down to the cat air pipe.
The ACV is no longer needed since it can not any longer pump air into the rear exhaust port.
Many of us removed the ACV to go to an aftermarkey secondary fuel rail.

thanks for the response, I may have to come back to this issue...got bigger issues now
since I've cut the bracket off the air pump, it bumps up against the turbo housing inlet. I've loosen the bolts and tried to spin the housing. It was originally pointed up 45degrees towards the center, in order for me to have clearance [and from what I've seen from other members] their inlet was pointed straight up or more towards the fender wall, but since I have short runners, one of the bolts flares out and bangs up against LIM. I can only spin it so far and it leaves a 1/8 - 1/4" gap from the flange to the motor.
The other thing is Sean from A-spec's phone is disconnected.
I was thinking about tearing it back down and re-milling the LIM , but Sean's already done it once and not sure if there is enough material without breaking the damn thing....
Anyone else have this issue?
