I have been building another Supra right now as well as working on an S10 that we drag race on Saturdays. I have all the parts together such as an AEM, 1000 cc injectors, the 1.01 T4 housing for the turbo and a 44 mm Tial wastegate with a 15 psi spring. I will start on the header as soon as I get this 90 model car done, but I'm not going to rush on it.
