Supra hands down, forged internals, you can make 400+RWKW on stock engine and gearbox no probs and there are heaps of example i can give. Unbelievable cars that are extremely underrated, try to get a newish one though 97,98 or even s15 isnt to bad as its light cheap to mod and maintain compared to 6cyl and will give you all the sideways burnout action you like, whilst also being reliable conisdering its a 2001mdl compared to 97 etc
