S5 T2 turbo hook-up
 

I know.............and I did look but I can't find the answer.

The turbo has a line that goes to the bypass air control valve but the acv has a block-off plate on it.

Should the block off plate be remove and attach the line or should the line be capped off?

Thanks

You can double click the pic to back it bigger.

The BAC is unrelated to the ACV. You can leave it just like in the pic, although the hose to the BAC is oversized and may leak under boost. The OEM hose can still be purchased from Mazda, which is what I did during my build.

Thanks for the help RotaryRocket88, but what I asked is not exactly what I meant. I think its a blonde thing.

Any way, I attached a new pic. Maybe it will help.

Should line A be connected to location B or should the line be capped off?

Thanks, Ashley

yes, A connects to B.

Wonder why the previous owner welded the opening shut?

he was retarded..lol

because he wanted to block it off.

take the coolant from the rear iron.

maybe he was running an aftermarket turbo and swapped it out when getting rid of the engine

thanks
