Posted September 26, 20195 yr comment_584782 View Advert NEW SU Needles - SM, SB, & SP For Sale , OBO For SALE , NEW SU Needles I purchased from SU Midel: http://www.sumidel.com/shop/category/-0100-fixed .... 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. For Sale are 4 sets of NEW SU Needles : $20 or Make an Offer , free shipping within the Continental US. (Discount on buying multiple sets). ........................
