Boost/Vacuum lines
imo....everything from the mani is the way to go. if u have a 10# spring in your gate, and u have it hooked to the turbo, and lets say u are losing 1# through piping....you're onle gonna get 9# total. anything off the turbo wont get a vac reference at all either. just an fyi
i been wondering about that also....where do i get springs? and say i have an 11psi spring what if i want to run 6psi on the street or say i put C16 in and want to run 15psi how does that affect the wastegate???ie will it make the wastegate function differently?
you cannot turn the psi below the preset level of the spring. if u have a 10# spring, u can only turn the boost up. I, myself, will be running 6# springs....with 2 10#, and 2 15# springs. I am just not a fan of boost controllers (personal preferance...i know many people who have great success with them).
You can get springs from most anywhere. There on ebay, and im sure there are several sponsors ----> who could help u out.

whoa whoa whoa...so if i get a 11psi springs i can run a MINIMUM of 11psi? but with that same spring i could run 15psi? so basically ill want a 6psi spring and then just use my Eboost to turn it up to 10-15 when i feel like it???

The force that opens the gate is the only thing that comes from the compressor when using the E boost. It reads boost level from the manifold... So it waits untill the right manipressure then opens the gate using pressure from the compressor.
If you run air to the gate plumbed from behind the TB it wont function well at all when the throttle is closed. The Eboost is very different in that it uses the same port as its gauge as the sense port for its WG trigger. It just MUST use the compressor housings nipple as a source for pressure to feed to the gate when it wants to open it.

So
Brake Booster---FPR--BOV--Boost gauge/reference port of eboost
The solenoid is a separate component of the system and should only be plumbed at the turbo.
Port 3 connects to the wastegate actuator.. The port that opens the gate.
Port 2 connects to the turbo pressure source on the compressor housing...
Port 1 is outlet for the air that's bled from the wastegate line or on wastegates with two ports it goes to the 2nd or "close" port on the wastegate.

guess im going to have myself a ball when i do it all..........1 other question if i take off the 1 vacuum line off the intake mani that routes to the valve covers and plug the eboost line into there can i just put breathers in each valve cover and not worry about pressurizing the crankcase,PCV issue solved?

Basically a little can with a breather on it that you route the VC breather ports to. Available from many turbo shops.
Make use of any available ports on the valve covers and route them to the can.. Eliminate the PCV valve from the VC if it is integrated to the port... We just swap the PCV for a normal NPT threaded barb.
Beyond that getting a vacuum pump is the only better way. The catch can with the breather on it works well but the vacuum pump will clear it out, cut windage and help ring seal... but it is $ome money more...

A quick place for any vapors and assorted crankcase crud to go... Same theory as a radiator catch can kind of.. Your breather filter wont get oil clogged, the volume of the can gives it a space to expand to helping ventilation...
It is comonly done on everything from DSM's, supras, RX7s and beyond.. It works.
