I have a question, how does boost control work in our cars?
say if i want to put a boost controller in, how do i put it in, and how does it control the seperate boosts etc.

also i was wondering what size and type our turbos are

I am not sure about turbo size, but I was reading your mod list and was wondering why you have a NOS direct port kit and if you have ever used it? I know it says "never used", but I didnt know if that meant you "have never used it" or you just "never really use it often." I have never talked to someone who has ridden in a Nitrous Rx7. Just wondering what it's like since a lot of people says rotarys dont take NOS well.

Sorry to be WAY off topic I was just really interested.

thanks,

Also, do a search for "boost control". There are a ton of posts on various manual (MBC) and electronic (EBC) controllers.

yea nitrous has never been used.
I am may be experimenting with it (and extra boost) this weekend
before people want to yell at me, its with a very small (wet)shot and a wideband. My afrs are already very rich.
IF you are seeing that i dont have a new ems, that is coming very soon. I want to see where my afrs go w/ stock ecu.

i wont let it lean out at all.

basically since i dont feel like shelling out money for a profec b right now,
-Does anyone have a writeup/diagrams/pics, or can just tell me how to make a home depot manual boost controller.

Some people use needle-valve MBC's - these still rely on the stock ECU solenoid control and may work somewhat erratically, IMO, depending on weather conditions, etc.

Ball/spring MBC's work very well. With these, the PC and WG exits to the solenoids are plugged, so boost and prespool are independent of the stock control system. There are several posts and info in the stickies (IIRC) on how to make these. I use them with excellent results. My modifications are in my signature.

I used a setup like "Dave W" is talking about with a Hallman RX boost controller. It is the Version II in the the diagram below.

goodluck
