I have a adaptor harness and tach module that will adapt a 78mm DBW TB to a 90mm DBW(car style only) throttle body to a 90mm intake, like TBSS, NNBS,fast,ls2, ect. It will not work on a 87mm truck style TB. I am using a truck TB, and it wont work for me. I bought it a year ago from cal speed and performance for a project build that I didnt get to until now. I used it with a ls2 TB for about 30 miles to get from my shop to home, and it worked good, but I never got above 3-4k rpm with it. calspeedperformance@gmail.com
Customer Service Phone: 661-387-0403 , this is the contact info from cal speed off my paypal if you want to ask them about this setup. looking for $150 shipped and insured. cheaper than a $220 dr-x if your going to use a ls2/ls7 90mm TB.



thanks
