Thank you unfamilia, i will get the diff, right now there is only availaibility of the celica diff LSD, i dont think the stock leaf springs will handle that weight or will they? i will also be lowering the car to quite some extend :), also the 3sge will have 4 throttle ITB's from a 4age 20v, and custom headers, next is cams and still stuck on going standalone or piggyback... plus 100 Shot nitrous :D :)
