Danbob99 Posted December 9, 2003 Share Posted December 9, 2003 I hear you guys talking about creating a manual boost control for your cars. I'm intested in learning a lil bit more about these, for i have a turbo in my EA82. I can't put it into my car yet, not untill i change my head gaskets, but i'm still interested in finding out mroe about these. Does anyone have a write up about the boost controlor? i looked in the parts or how to section, but there weren't any to speak of. If any one could offer some help...it would be much appreciated. Thanks you Dan Link to comment Share on other sites More sharing options...

Warp3 Posted December 9, 2003 Share Posted December 9, 2003 I and some others on this board, built ours based on these instructions (with some minor variance for parts fitment/availability). http://www.geocities.com/chmwatson/FAQs/mbc.html The parts list on this page is pretty much identical to the one that Scrub2k listed above.

Warp3 Posted December 9, 2003 Share Posted December 9, 2003 FYI, the 5/16"-18 adjustment screw from the instructions was WAY too small for my application. I'm guessing the 1/4" NPT parts they used in those directions had much thicker walls than the ones I had (I got mine from the plumbing department, not air tools, so maybe that's the difference). My suggestion would be to buy a 1/4" BUSHING (instead of a male-to-male coupling per the directions). It's basically the same thing you are going to make out of the coupling, but already has part of the work done for you and costs almost the same price (you don't have to hacksaw one connector off as it only has one connector to start with and it's already tapped partway through on the inside making the tapping step go MUCH faster and easier). Then go to the hardware section and find out what thread the inside is of the bushing is and buy that thread bolt and nut combo. I ended up using a 3/8"-24 on my MBC (since I ended up using a bushing that came with one of my Autometer gauges that was already tapped for that size).
