2G No lines for BCS

[MasterMatt209]

I have two 4g63 2gs and while trying to get my second one running I noticed there were no lines going to or from the boost control solenoid, I know where the lines should go. But I was wondering why would someone do this, and what affect would this have on the car? Even more interesting I look at my other 2g and see the same thing except it has a hose going from the wastegate to the nipple on the turbo.

Car one: adjustable aftermarket blow off valve, otherwise all stock. Nothing connected to BCS.

Car two: all stock besides an egr delete. BCS is not capped off with nothing going to it, wastegate and turbo nipple connected.

Advice for cars given?

They probably replaced the bcs with a manual boost controller.

There is no boost controller on either car, unless they really hid it somewhere. But to my knowledge they both do not have that

The wastegate would open sooner if hooked up direct, the BCS bleeds off some of the wastegate signal which delays the wastegate opening giving you a little more pressure.
If the BCS is disconnected someone probably at one point had a boost controller installed then removed it and hooked the wastegate up direct without trying to reconnect the BCS, no need to if you are selling a car really.

So can I leave it the way it is? If so do I need to cap off the BCS? Or should I just revert to stock route.

So I researched a little and anyone correct me if wrong, but apparently you can disconnect the BCS, cap off the intake nipple and then run a hose from the wastage to the compressor housing and the car will run off the wastegate pressure which is about 10-11 pounds and be done with it. Correct?

Yes.

 

[joshjordan]

that is correct.
