edekalil Posted July 26, 2015 Report Share Posted July 26, 2015 My friend has a set of I believe 38mm carbs roundtop carbs look like SU type made by Hitichi. He only has the 2 carbs. What other components will I need to make these work. Eddie 1 Quote Link to comment
spottedog Posted July 26, 2015 Report Share Posted July 26, 2015 a intake manifold is needed. 1 Quote Link to comment
datzenmike Posted July 26, 2015 Report Share Posted July 26, 2015 There were at least two Nissan intakes a K14 intake or 210? Not sure on the 210. You will also need all the linkages and choke cables. 1 Quote Link to comment
ByStickel Posted July 27, 2015 Report Share Posted July 27, 2015 All you need to do is to send 'em to me. I have the intake and will get them set up. My first l20b car had them and they were great for street use. 1 Quote Link to comment

My first l20b car had them and they were great for street use. My friend dropped off the carbs today so get that intake manifold ready for me. Just kidding, I will post some oics tomorrow in the morning. Quote Link to comment
edekalil Posted August 13, 2015 Author Report Share Posted August 13, 2015 These are the su carbs my friend gave me. The opening is 1 3/4" . Quote Link to comment
Dolomite Posted August 13, 2015 Report Share Posted August 13, 2015 Aren't the square flanges Z carbs? I have the flat tops which are supposed to be nearly identical to the round tops, they have 2 bolt flanges. Edit: 1 3/4 should be 44mm, too much for a 4cyl. Quote Link to comment

You are probably correct I really know nothing and did notice what you are saying here till this morning when I took the oics. Any way I got them for free I do have a set of the flat top su setup that should have all of what I need I guess when I need them. Quote Link to comment
Sealik Posted August 13, 2015 Report Share Posted August 13, 2015 Edit: 1 3/4 should be 44mm, too much for a 4cyl. ?????....Depends on the 4 cylinder. Those look like the early 240Z 46mm roundtops. The K14 or 220 intake will have to be opened up to 46mm.....and you'll have to profile a set of needles to get your A/F ratio numbers in 'order'. Quote Link to comment
