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 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.

  3. I bought some thin offsets (~1/8" thick) for the fronts so I didn't have to flatten much the wheel bearing cap. It also allowed the rim to slide over the hub easier. Once I had the offsets centered properly, I used a small amount of plumber putty between the hub and offset to hold them in place for when I remove the wheels so as to not alter their position. These have been great for 10yrs now with no shimmy or vibration when driving at high speeds. Had front end alignment done and good to go! https://www.summitracing.com/search/brand/gorilla-automotive/product-line/gorilla-wheel-spacers/part-type/wheel-spacers?SortBy=Default&SortOrder=Ascending&N=thickness-in%3A0-125-in My 73 has 16x7 Konig Rewinds with 205/55/16's on the front and 215/55/16's on the rear (The rear tires are about 1/2" wider but give me an accurate speedo reading). Love the Konigs, they were much lighter than my cast iron rims that came with the car. Plus easy to clean.

  9. Great on your approach... SU roundtops are great ... ZTherapy does a super job refurbishing and updating them for current fuels.
  10. 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...
  11. 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......
  12. 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......
  13. 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....

  14. 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....
  15. 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....
  16. What are the Needles used with this set? Especially for an L24 stock type engine config. Many thanks.....
  17. 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 ...

  20. Sweet Wheee (Mark), thanks for the comment!! Would love to see pics of them when you can send them..... Essentially we have 40yrs of technology difference between the 370z and 240z.... but being gated they both put smiles on our faces!!!!! Take care... Mark
  21. Many thanks for sharing! Great info to always check these fuel bowl/nozzle hoses when I pull the Airfilter backer plate. I am very much like you as I often fiddle to assure the engine components are always working to spec so I can head off a problem before it fails completely. Started to have bucking/jerking when accelerating or going up hills, a loss of power problem. This occurred after installing ZTherapy SU's and tuned them with Colortune also. Thought it was my SU's and needed to tune/tweak them. Finally after it finally stalled completely and would fire sporadically but not run I figured electrical problem misfiring? Got it back to my garage I thought to check the rear fuel bowl for the heck of it since it was easy... and sure enough it was almost completely empty. Front fuel bowl was topped off pretty close to normal. Replaced the mechanical pump and then added an electric pump for insurance.. my 4BBL Holley was more forgiving when the mechanical pump was marginal ... my SUs were not! Thanks again for sharing....
  22. Nothing but Gated Garaged Vehicles !!! The thrill of driving stick always puts a huge grin on my face .... 1973 240z (Viper Dark Green Pearl), 2005 Ferrari F430 (Rubino Micalizzato-Burgundy Pearl), 2002 Ferrari F360 (Rossa Corsa-Red), 1991 Toyota MR2 Turbo (Red), 2010 370z (Black Cherry).
  23. Ah..... thanks. My initial thought the Right Lever was for the Air Box flap (close it for cold startup)..... but never thought it was for the gas pedal. Thanks!
  24. My curiosity is getting the best of me so I decided to ask the experts here.... maybe I am brain dead and missed something, I have searched on this site and cannot find any explanation. Q1) What is the Right Lever for on this 240z choke assembly? Q2) Is it specific to a Year? Many thanks...
