ok so i found this supra an 88 7mgte targa manual for 600 dollars guy bought it from a friend of his who after replacing the head gasket couldnt get fire to the starter and after looking under the hood when i went to go look at the car i knew exactly what was wrong and fixed it but he had jerry rigged so much of the electical and other things under the hood that i need some help figuring out how things are sopose to be. first off i got the starter to work but its backfiring through the intake and im also curious if i could get a picture of the bracket for the throttle cable going to the stock intake manifold. and if someone could tell me a few of the basic things to look out for im new to the supras but not new to toyotas ive owned a few celicas and done a lot of work to them. ive been doing some research and i have an aftermarked intake manifold and a t4 turbo manifold and the upgrade for the ct26 turbo. the car already has a three inch down pipe on it but the guy just left it wide open under the car. any help will be appreciated thanks
