Hi. i am usingt a rhb5 turbo. On the Internal wastegate there is a vacume nipple and right next to it on the tubo housing thee is one to. Right by where the pipe comes out for the intercooler. Someone told me to hook them together. Is that what I am supposed to do? Thanks

U can, I did it B4, but switch it.

I plugged mine up and run the wastegate

one to another vacuum source, mine is on the PCV

valve.

I'll work but your wg will open a tad slower. I blocked off the comp housing fitting and used my vac mani as a vac source which is tapped off brake booster.

use a 5/16" plastic T where it has 2, 5/16" barbs and one 1/4" barb. the 2 5/16" barbs will be for the charcoal emissions canister vacuume line, which will be one of the larger vacuume hoses on your intake manifold. the other large vacuume hose is for the pcv valve. T off the large vacuume hose on the intake manifold with the 5/16" barbs, and the one 1/4" barb on the T is for your wastegate. take the nipple off the compressor housing and fill it up with jb weld so it's pluged. for your BOV you can T off the PCV valve. use the smaller hose clamps to secure the vacuume lines. this is how i did mine and it spools up about 1000rpm faster til full boost then when i had my wastegate
connected to the compressor housing. do not T anything off the FPR.

Thakns for the info. One more question. I have a 94 civic. Should I run the coolant loop off the intake manifold or the little nipple on the throttle body?
