I just purchased a new/used HKS wastegate. Its used because it didnt have all the parts but it was never put on an engine.

My questions are as follows.

1) when installing the wastegate lines, and using a MANUAL boost controlled, how do i hook up the top barb and the bottom barb.

2) the wastegate didnt come with the top or side barb, anyone no where i can pick those up??

Thanks.

 

the barbs are just 1/8" npt. use the top barb if you use an electronic boost control, and hook the lower one directly up to manifold pressure (straight line from the plenum) good luck!

 

ok, two more questoins.. now, im using a MANUAL boost controller.. so how do i hook that up??

And you say straight line to the plenum, can i TEE off the fuel pressure vacuum line for the fuel pressure regulator.

side barb goes straight to a vacuum source on the intake manifold. boost controller gets spliced inline of the vacuum line from WG to intake manifold
