  • About my Cars
    I owned a Datsun Dark Blue 1971 240z from 1977-1982. Bought it for $2400 with 42,000 miles. Never used in winters and eventually sold it June, 1982 after our1st child was born (for the same price I bought it for - $2450 with ~63,000 miles. My 240z interest was renewed as I purchased my 2nd one (Orange) in Oct. of 2006 and my 3rd one (Green) in July of 2007. Both recent 240z's are 1973's, Orange 11/72 and Green 9/72. Moved from MN to NY in '08, sold the Orange 240z and kept Green 1973 240z, HLS30-124668. In 12/2010, purchased my 4th Z, a 370z Sports Package in Black Cherry w/6spd Manual.

  3. Great on your approach... SU roundtops are great ... ZTherapy does a super job refurbishing and updating them for current fuels.
  4. This looks like a great car , body looks awesome. Just a thought, depending on what your thinking of doing to the car in the long term... with all the engine parts out you may want to consider getting the engine bay painted Blue to match the exterior unless you intend to convert back to original Orange. But in general the car looks really solid and great !!! Keep us posted !!! Did your '73 come with SU Flat Tops? Wonder what your plan is for carbs...
  5. Bump on this thread.... Wanted to let you all know I have extra sets of "SB" (2 sets) and "SM" (1 set) needles. They were too rich for my L24 config so am selling at a good price for anyone who uses them. I am currently using "SL" Needles with very good results... as it's close to the N-27 stock needles. Many thanks......
  6. Just wanted to let you all know I have two(2) extra sets of "SB" and "SM" needles. They were too rich for my L24 config so am selling at a good price for anyone who uses them. I am currently using "SR" Needles with very good results... will try the "SL" Needles which are the closest to N-27 stock needles at some point in the future. Many thanks......
  7. Regarding your Carbs running possibly rich.... until you get your O2 meter hookup (for each Carb?) I'll share what I did becuase I didn't want to install two O2 sensors for each SU. 1) I used Colortune 14mm plug and this technique for fine tuning Carb A/F mixture on cylinder #2 & #5 for twin SU's . At Idle and 3000 rpm ... plenty of Youtube videos on this... https://www.amazon.com/Gunson-G4074-Colortune-Single-Plug/dp/B0012MB4VE/ref=pd_sbs_263_1/139-8508085-4072005?_encoding=UTF8&pd_rd_i=B0012MB4VE&pd_rd_r=0c081181-9cc0-11e9-b500-9959ee5ce66b&pd_rd_w=6PqYJ&pd_rd_wg=arPBD&pf_rd_p=588939de-d3f8-42f1-a3d8-d556eae5797d&pf_rd_r=R68MTQD1GKPP7VZV8M3G&psc=1&refRID=R68MTQD1GKPP7VZV8M3G Video : 2) Then used this manual page (attachment) referring to page 11 "Testing Procedure" . Under load so it gave me a good indication that my "SM" needles were too rich during pickup/cruising... so now I am running "SR" needles which are closer to N-27 stock needles and the car runs great. Page 45 has the needle profiles for comparing "SM" vs "SR". I know you have Triple Carbs... but thought this approach may add to your fine tuning approach... Good luck....

  8. Hey Duffy... congrats on both getting married and testing your car.... Just one observation on your noises.... Crack Sound - maybe be a U-joint / Drive shaft or side axles ... maybe add some grease? rotate when car is on the ground check for play.. Good luck.... keep us posted....
  9. After putting in new lash pads/rockers and springs I decided to replace my marginal oiling bar. Lash pads/rockers 5 & 6 had excessive wear due to poor oiling. I went with the straight oiling bar for racing which I purchased from Larry Hassler who is on this site (larryracer240z@gmail.com or (626) 485-5767) See pics..... this bar actually adds rigidity to the cam towers, it's aluminum so it expands/contracts with the engine head nicely. Note that 3 webs on the valve cover must be cut back to allow the bar to clear it. See pic #2. I am pleased with it....
  10. What are the Needles used with this set? Especially for an L24 stock type engine config. Many thanks.....
  11. Hey .. I live in Brier Creek , Raleigh NC .... if I know of someone interested I'll send them your way. Any engine pics? Is the engine bay Stock Orange or Red? Mark ... cell: (507) 208-0140 ...

I purchased a variety of needle tapers to optimize ZTherapy SU's in my 240z L24 setup - "SM's" were too rich for my engine so I dialed in the carbs nicely so far using "SR" profile needles. I included the Taper profiles(attachment #1) along with the tuning method (Attachment #2, page 11) I used for optimizing efficiency with performance(I also used Colortune but did not have an AFR for real-time mixture readings). I am very happy with the "SR" needle right now as it's just slightly richer than N-27 stock.... the other one actually closer to stock N-27 is the "SL" which I am also keeping. Therefore , For Sale are 6 sets of NEW SU Needles : Make an Offer that includes shipping within the Continental US. (Discount on buying multiple sets). ........................
