Josh K. Posted April 11, 2015 Author Report Share Posted April 11, 2015 Honestly my plan is finish the metal work and then shoot it with plastidip flex blue (not dead set on color). Eventually do a real paint job. Quote Link to comment
Josh K. Posted April 12, 2015 Author Report Share Posted April 12, 2015 All clean and fresh paint. Ready for assembly!! Quote Link to comment
Josh K. Posted April 12, 2015 Author Report Share Posted April 12, 2015 Looks like during one of the 6 moves I lost my starter. Lame. Spending $150 on a starter is gonna hurt my progress.... Gotta find a used one. Quote Link to comment
Josh K. Posted April 12, 2015 Author Report Share Posted April 12, 2015 Jeff is gonna hook me up with a pile of starters.. Gotta be a KA starter in there :) 1 Quote Link to comment
q-tip Posted April 12, 2015 Report Share Posted April 12, 2015 I think I have one I the garage, its not new but I think it works. Quote Link to comment
Josh K. Posted April 12, 2015 Author Report Share Posted April 12, 2015 Went to work to sand blast some parts. Decided the pulley didn't need the back set of grooves (power steering?) anymore. Because why not.... 3 Quote Link to comment

Josh K. Posted April 13, 2015 Author Report Share Posted April 13, 2015 I needed to hook my MAP sensor up somewhere..... I decided I would make a block off plate where all the Idle Control junk went (Not running idle controls) in the end of the plenum. I'll drill and tap 3/8"NPT, connect a hose to the firewall where I'll have a T manifold bolted to the back side (inside) of the firewall. One side will run to the MAP sensor and the other to the boost gauge. Here's the plenum end: Here's the plate I whipped up: I wanted a direct clean source. I think this will work. I also started planning my crankcase ventilation. I'm gonna use the stock breather box like the one below. I'm going to install a port in the box and run a vac line into the cabin to a valve that connects to my boost gauge. This way I can monitor the crankcase pressure whenever I want.: I'll run it through a check valve and into my catch can. I might make a new one with a reed valve to eliminate the check valve. I'm going to use this Vibrant slash pipe in my exhaust to pull vacuum: 1 Quote Link to comment
Josh K. Posted April 14, 2015 Author Report Share Posted April 14, 2015 And done..... 2 Quote Link to comment
datsunwizard Posted April 14, 2015 Report Share Posted April 14, 2015 Build a venturi in the exhaust before the E-vac port, ( We called this system "pan vac" in the old days) It will pull more vacuum. Also put a one way check valve on the line from the crankcase to the E-vac, at low rpm you don't want any exhaust flowing into the crankcase. When we used this system, we could shut off an engine, let it sit for like 10 min, then pull the dip stick ,and the crankcase would still have vacuum it. To use this system efficiently, the motor must be tight, good seals and low leak down. We used total-seal rings (2 piece) for the lowest leak down. 1 Quote Link to comment

I'm not sure what you mean by building a venturi into the exhaust? Can you provide a sketch? Thanks, -Josh Quote Link to comment

datsunwizard Posted April 14, 2015 Report Share Posted April 14, 2015 No, like this; Not to scale Sorry for the quick poor drawing, but gets the idea across. Personally, I would not use the pre made one E-vac one, with your skills I would make my own. The venturi speeds up the air flow, creats a low pressure area on the backside of the venturi. We would use a EGR valve for the check valve ( can handle the heat). Hope this helps. Quote Link to comment
Josh K. Posted April 14, 2015 Author Report Share Posted April 14, 2015 That's perfect. I was looking at venturis and that was the one that seemed like the best design. Thanks! I'll model something up today! 1 Quote Link to comment
datsunwizard Posted April 14, 2015 Report Share Posted April 14, 2015 No problem, we would basically make a cone for the venturi, flatten out (camfer) the edge. Also realize that from a smog stand point, this isn't very green system, all blow by is pulled into the outside, so you must have a tight engine to minimize the effect. Quote Link to comment

Josh K. Posted April 14, 2015 Author Report Share Posted April 14, 2015 So after much thought, talking with some engineers and digging into the depths of google I decided to go with the Vibrant E-Vac system. Reason being is it actually creates it own Venturi effect with little restriction. To make my own internal venturi I would have to kill my exhaust flow from 3" to a theoretical 2.25" exhaust. 1 Quote Link to comment

q-tip Posted April 17, 2015 Report Share Posted April 17, 2015 No problem! Was it still secured to the box when it got to you? Quote Link to comment
Josh K. Posted April 17, 2015 Author Report Share Posted April 17, 2015 Yup. All snuggled in there. Quote Link to comment
q-tip Posted April 17, 2015 Report Share Posted April 17, 2015 Good, didn't want it banging around trying to get out. Quote Link to comment
Josh K. Posted April 19, 2015 Author Report Share Posted April 19, 2015 :) Back to work making shit pretty! Still need to buy hose and ends for the breather system. Looks like it will be just fine.... ;) 2 Quote Link to comment
