Huh? Are you running the stock bosch diverter (aka bov)? I swear i can see it in the picture. To the right of the wastegate.

My bad your right ! Wg and bov

 

Did you simply relocate the bosch diverter onto the air pump hole in the aftercoooler? Or did you weld on a 1inch pipe to attach tbe diverter to?

My concern is compressor surge at wot shifting

I didn't do any of the work but I'll ask the guy that did it was done by minitoyota and jeff evans by the way... Evans used a similar setup on a road course civic many yrs ago..

 

WG before aftercooler, the way it should be done

Looks nice! do you have radiator fans already mounted?

 

Please do. Sos provides a nipple that is smaller than 1 inch for the factory air pump. My concern is that they simply relocated the valve to that nipple, rather tban cut it out and weld on the proper size.

And again, i recommend running larger than the 1 inch valve. However, seeing as how you are bleeding off all the air that would normally net 18ish psi, you might be fine with the stock diverter.

Fans are installed in the above pics. There is just enough clearance from the wg to fans in that location.

The air pump nipple was cut off, enlarged the hole and we welded a 1" pipe on.

 

Anyone consider using a restrictor to limit top end power?

 

Looks a lot like mine
