Consider volume of vacuum, I think I used 3/8" PCV hose (it matched the barbed fitting on the checkvalve). Use the PCV style hose on a spool (from the typical parts store) so it doesn't collapse under vacuum, especially after exposed to heat and oil from the plenum. Easiest way without waiting on the distribution block would be to T into the PCV.

OK cool thanks. Is that how the kirban kit is ran?

No, he sells one like I have. It replaces the black plastic block on the throttle body. The port that is angled back on the right goes to the brake booster.

See the larger port on the top left? That goes to the PCV, it has a larger port so that's why some people T into the PCV.

How would you run it?

The billet vac block with the extra 3/8" fitting is easiest I reckon. Just like an 89 TTA

Go with the new vac block. Nice and clean. Looks factory.

Hydroboost!!! It's really not that much more difficult than the vacuum. It's just the added hoses but it is nothing to be deterred about. It really is easy once you get the alternator and tensioner bracket off. I think not having to take the pedal off when going from powermaster makes it an even keel with the vacuum swap. Nothing against vacuum but in my personal opinion you get better clamping force with hydroboost. It really isn't that much more expensive too. I bought all my parts from rock auto and spent $180 all together minus the return tee ($1 at any auto parts) and the return hose (like another $5). I wonder if anyone has done a side by side comparison on vacuum and hydroboost with stock brakes? I know my stock front brakes with s10 stuff on the rear damn near slams me to the windshield and can hold almost 15psi on the street on cold tires. I can't wait to see what I can launch with at the track on warmed up drag radials.

See this thread on performance of vacuum brakes. I'm not saying they are better than hydroboost. I'll just say that they do the job!

Is there a universal model similar to this one i can get at the auto parts store?

 

[87-WE2]

My setup is the gbodyparts kit. It comes with pedal, master cylinder, booster with check valve, and vacuum block with hose. Paint the booster before installing. I also swapped to s10 wheel cylinders and shoes.
