From what I have heard, most supra people are putting in dual walbro's. And as of why I am asking, I am preparing for a project that will happen later this year...well, maybe not later, but this year. I'll let you know when I go single, its not secret. Besides, I'll prolly need help with the tuning. First project is the 6spd, then AEM ECU, stereo system (working on as we speak), suspension, fuel, some body work, then single (maybe big twins)
