From what I can see, the KB kit does not include an 8 rib belt or injectors etc. The Tork Tech kit was featured in the Feb. Issue of Superfords Magazine. There are dozens of guys on Stangnet who have purchased and installed the kit with awesome results. At 8-9 pounds they are at about 400 rwhp. At 18.5 pounds of boost, a 99 Saleen with good rods and pistons is putting down 590 at the tire with the same kit, bigger lower pullet, smaller upper. Bigger injectors and fuel pumps of course.
