japscrap Posted August 26, 2013 Author Share Posted August 26, 2013 Alrighty guys it has been awhile since I made a post about this journey. I have hit a couple road blocks along the way that have hindered the progress. One was I blew up the R200 in the Z while I was having a spirited driving experience. The second one was I sold my 1972 Ambassador wagon and purchased a car that would save me some money. Both in the miles and smiles per gallon, the new car far exceeds the old in a lot of ways. The new car to the fleet is a 1979 280zx. 131,xxx. the P.O took out the EFI, and put a clifford with a edelbrock 4 barrel. The newly purchased car came with a rear end that was originally in the car as a spare, the P.O. put in "Steeper gears" as he put it. The interior is in good condition with little flaws here and there. I have had to get this one up and running tops to daily drive while I fixed the rear diff. So those two speed bumps along the way have really set me back for completing this project. But none the less I am moving forward now.The pictures are a bit older, goldy has matching wheels all way round, and the lazy lady (the red one) is now sporting the old chrome 2 piece 14 inch wheels.ANYWAY lets get back on topic, so I shot a update video.here it is!

ZXT_bean Posted September 14, 2013 Share Posted September 14, 2013 I like the idea of using a rocker box! that should look really slick once its all together Quote Link to comment Share on other sites More sharing options...
madkaw Posted September 15, 2013 Share Posted September 15, 2013 What a cool idea:) http://forums.hybridz.org/topic/96528-cai-for-triple-mikunis/?hl=%2Btriple+%2Bmikuni I would have done it different though for the turbo app. Keep up the work!!

Xnke Posted September 15, 2013 Share Posted September 15, 2013 Remember the HKS box has internal baffles as well as the two inlet points. We have a few threads on the box design here, or PM TonyD, he's built a similar-design airbox at some point, I think! Quote Link to comment Share on other sites More sharing options...

japscrap Posted June 16, 2014 Author Share Posted June 16, 2014 Howdy guys, I have not been on a car forum in a long time. I got a update video for you all. flame on? Quote Link to comment Share on other sites More sharing options...
madkaw Posted June 16, 2014 Share Posted June 16, 2014 You've made the same mistake I did . That car won't do squat until you fix it. You have covered up your vent holes with your back plate. Take it back off and you will see what I mean. Check out my Mikuni thread. Quote Link to comment Share on other sites More sharing options...
japscrap Posted June 16, 2014 Author Share Posted June 16, 2014 (edited) I did NOT cover the vent holes up. watch another pt 8 or pt 7 you will see. Edited June 16, 2014 by japscrap Quote Link to comment Share on other sites More sharing options...
japscrap Posted June 16, 2014 Author Share Posted June 16, 2014 (edited) the car is running race emulsion tubes, along with me retarding the timing a hair. it was running rough, but again it was just to see it start.

madkaw Posted June 16, 2014 Share Posted June 16, 2014 I guess I thought the float bowls had to be pressurized equal to whatever KPA your running. Quote Link to comment Share on other sites More sharing options...
japscrap Posted June 16, 2014 Author Share Posted June 16, 2014 kpa? sorry for my lack of knowledge! Quote Link to comment Share on other sites More sharing options...
madkaw Posted June 16, 2014 Share Posted June 16, 2014 Thought the bowls need to be pressurized to maintain fuel pressure and level Quote Link to comment Share on other sites More sharing options...
japscrap Posted June 17, 2014 Author Share Posted June 17, 2014 we shall see what I run into. it will not be hard to change the back plate or modify it. I work at a metal manufacturing facility complete with every tool/machine I could need. do you have a link to your build/ the one you would like me to once over? I thought the bowls will be pressurized with the boost reference regulator. sorry if I am missing a key part here guys... Quote Link to comment Share on other sites More sharing options...
madkaw Posted June 17, 2014 Share Posted June 17, 2014 (edited) I'm no turbo guru but my understanding is that the float bowls need to be pressurized along with the rest of th carbs. The effort will be to keep direct air forces away from the vent opening. Triple Mikuni help thread Edited June 17, 2014 by madkaw Quote Link to comment Share on other sites More sharing options...
madkaw Posted June 17, 2014 Share Posted June 17, 2014 By the way- watching with MUCH interest. You have a very nice project going there! Quote Link to comment Share on other sites More sharing options...
japscrap Posted June 17, 2014 Author Share Posted June 17, 2014 Thank you very much. I much appreciate that, and the help and info! I will browse your thread when I got some free time~! Quote Link to comment Share on other sites More sharing options...
japscrap Posted June 17, 2014 Author Share Posted June 17, 2014 I have been doing a little image searching whilst on break. I should drill a hole for the vent on the upper left hand of the dcoes so boost pressure also goes into the vent hole..... correct? also making sure it is sealed with a nice O ring or what not.

japscrap Posted June 17, 2014 Author Share Posted June 17, 2014 http://img.photobucket.com/albums/v208/935motorsports/stuff%20for%20sale/surg3.jpglooks like the back plate comes off and I drill 3 vent holds cake walk~! again thank you guys for the info along the way! all the posts are appreciated.

Tony D Posted June 17, 2014 Share Posted June 17, 2014 Carburettors operate on pressure differential. If you don't equalise the pressure at the entry of the carb, with that on the float bowl, it makes your fuel level move all around. Early cars did not have that vent, if your filter clogged, you choked the engine out. Choke Playes do the same thing. That's why PHH's don't have a "choke lever" they have a "starting circuit" which performs the same function but in a slightly different way.
