hey guys. i just bought my frist car . 1989 toyota supra 7MGTE. the engin was rebuilt with upgraded head gaskets, turbo is boosted to 12psi, full 2.5 exhust. it wouldn't start tell i replaced the already new battery which was corraded with the green death corrosion. it had a hard time firing the frist time. then it was fine. it seams to be lacking power though. although i have never driven a supra before. i think it should pull hatrder that my buddys civic with b16. problems: the odometer and dash...
