Simplified Sequential

[David Jerome]

For those who know me very well at all, they know I pretty much despise the stock sequential setup. I love it the 10 minutes of the year it performs correctly and Im sure it was probably great in 1993-1998 before people started pulling these cars apart, however, it is very rare to find them working correctly these days. Since I buy and resell fds and try to sell them as properly running cars, I almost always convert them to Non-Seq if I am doing a rebuild on the car also. This minimizes my headaches during the rebuid period and also the period after I sell the customer the car because if they have any boost issues or really issues at all it is pretty simple for me to diagnose over the phone.

Well, for whatever reason I decided to put the last car I bought back together as a proper running sequential car(shocking I know ) As I have been looking over the simplified sequential chart I have ran into some questions about the necessity of some of the simplified setup.

The lower vacuum nipples on the wastegate control solenoid and turbo precontrol solenoid are "T'd" into the vacuum lines for the oil injectors for the oil metering pump and ran into the plastic primary intake elbow. What is the reasoning for these lines being ran into the plastic elbow. I know it provides a slight source of vacuum, but is this really necessary? This is one area of the FD I can honestly say I could stand to do some more studying and learning. In the past I have only dealt with the Sequential setup when a customer wanted me to and that was it.

Hopefully some of the experts can chime in on this and this thread may provide some helpful information to forum members in the future.

I will attach the pic below.
