I am currently building up a 92 spacecab hilux with a 4 link rear and 5 link front. It has a 587hp single turbo 2JZ.
But just purchased by brother 90 model dual cab with a 1KZ-TE in it and a RUF conversion with my 37's of the other play toy on it. Just trying to find the best/cheapest way to get safe power out of it..?
