This here is the other setup with a tee connected from the boost source.

You can get rid of the T, you have it set up correctly the first way though the other way should work if it doesn't create a vacuum/boost leak at the other end. Leave the BCS connected to its electrical stuff and just remove the vacuum lines. Don't forget to start with the MBC turned all the way out, and you might want to get slightly longer lines so you can mount it somewhere more easily accessible, I mounted mine to the top of my passenger side radiator fan.

When i remove the vacuum line do i plug the open end? And thanks.

Its better if you cap it closed.

God damn that WG is rusty.

Simply remove the pair of vacuum lines from the BCS, you don't need to plug the BCS as you will be removing both hoses to it, you WILL have to plug the small nipple on your intake tube that the BCS ran to, for "leftover" parts when you are done you should have two rubber vacuum hoses that run into some shielding that holds them together, nothing else needs to be removed.

By removing the stock BCS, your car will stall while slowing down. Had this happend to my 1g and 2g. after I installed a MBC, i took out the stock BCS, took it for a test drive, then you'll notice that the idle is really low like its about to stall or does stall while slowing down. so its better off leaving it on and just plug the nipple on the stock BCS.

Thats EXACTLY where I decided to put my hallman Pro RX. You don't need the tee, just run the line from boost to mbc then out to WG actuator. I just plugged and removed all other vac lines.

The only other thing you may consider is getting slightly longer hoses and mounting the MBC in a place that's a bit more convenient for adjustment. Plus, you'll probably burn your hands less.

Just want you to learn from my mistakes.

Actually, I think that's why we're ALL here on this site.

If you just looked at the last photo in the link I gave you, there really isn't much else to say.

I put mine right on the valve cover as shown below...

Thread Jack, this is how my Hallman Pro MBC is set up.

So, it might be kind of hard to see, but the vacuum line that is perpendicular to the MBC is going to the wastegate, and the vacuum line that is inline with the knob is going to that black pipe. Is that right? Or did I eff everything up?
And one more question.
Here is a picture of my 1990 intake mani

There are 2 ports on top, and 2 on the side. If I call them A/B on top, with A being the one closest to the firewall, and C/D on the side, with C above D, I have C and D ran into each other to prevent a vacuum leak, A capped, and am using B as a source for my Boost gauge, but my gauge is only reading like, 2 psi?
Now, I know the stock gauge is garbage and inaccurate, but is it so inaccurate that it reads me hitting a full 14lbs while my autometer is only showing like, 2/3psi? Or can I not get an accurate reading from that port?

Ok guys I have a question, everywhere I look it shows that the manual boost controller goes from the wastegate to the turbo housing and that's where I'm stuck my turbo doesn't have a nipple on the housing to connect it to. How do i hook it up can someone please help?

Try not to bump old old threads, just start a new one. Also, search is your best friend.
