RacnJsn95 Posted November 12, 2008 Report Share Posted November 12, 2008 Some years ago, when I was big into Z cars, I noticed a set of "strange" SU carbs on ebay. They were listed as being off an early 240z, but they were flat tops. I was going to shine them on, but I noticed that they weren't your typical square mouth flat-top SU that people tend to junk in favor of the round tops. Upon closer inspection of the pictures, they appeared to be a normal round mouth SU carb, with flat-top dashpots. I wasn't sure if the dashpots were interchangeable, but I bid to win, and didn't have much competition, and won them complete with manifold & linkage for about 75 dollars shipped to my door. I contacted Z therapy about them, they they turned out to be JDM carbs off an early fairlady with an L20a. They have a smaller bore than the Z or 510 carbs. I bet they'd be killer on an L4!

Duke Posted November 12, 2008 Report Share Posted November 12, 2008 My 510 had a set of flat tops on the L-18 that came with it. If you de-smog them, they are the same as the 510 round tops. They ran like a top for me. Quote Link to comment

It can be done, but I wouldn't recommend them. The Hitachis are a better design IMHO. Quote Link to comment
