Guest Anonymous Posted July 30, 2001 Share Posted July 30, 2001 Hey guys, I am new to this forum, and I have a ton of questions about my Z. I have a (prod. date 8/71) 240 Z with a 77 motor and trans mated to a beautiful set of DelLorto carbs. They rock, I love 'em. The question comes to mind that I may need to re-jet because if I dump the throttle, I get lag. I have a Nismo L( slalom cam, and I have no idea as to what my rocker dim's are. I have the DHLA 40mm carbs, but I have no idea what size jets are in it. I have already spent some cash with CB performance, so I know where to get parts. My powerband seems to be in the 3500 RPM + range . It pulls great, but I could use some more low end power.What do you think? Sincerely, Z 4 Z Quote Link to comment Share on other sites More sharing options...
DAW Posted July 31, 2001 Share Posted July 31, 2001 There's a book, ISBN 1 901295 64 8, "How to Build & Power Tune Weber & Dellorto DCOE & DHLA Carburetors", Veloce Speed Pro books. Get that book, then ask for supplemental suggestions. The book will walk you through proper jetting and tuning. I lived in Naples, Italy for a couple of years and I used to peruse the junkyards there looking for Webers. I brought back many dual sidedraft setups, some from Alfa Romeo police cars. I picked up Weber, Solex, and Dellorto 40mm duals. I was surprised to find that many of the Italian mechanics preferred Delorotos, as I always assumed Weber would be the top dog.
