just got my ebay turbo kit for 98 d16y7, and the wastegate has 2 out/inlets and the blowoff valve has 1. also the boost controller has 2 outs/ins. which is the best way to hook up everything. also included is a t-fitting.
I would have to see the boost controller to tell you whats what but this is what is should be: Bottom of wastegate to boost controller - boost controller to vacuum source (fpr, etc). BOV to vacuum source.
Is it internally or externally gated. If external do what I said and then plug the nipple on the turbo, but if internally gated I believe you run them together and put the boost controller in line with them..
it is an exernally gated one. has a outlet on top of the wastegate and a outlet on the side pointing directly at the turbo. the boost controller is one of the ebay cheapy ones. has two outs/ins on it. got the intercooler and piping ran last nite and the blowoff is ran to the fpr vacuum and all hooked up. now just got the wastegate and boost controller to figure out before i put the turbo in
