get a supra rx-7 subaru wrx sti even better 3000gt and those cars u can blow the doors of the ford for relativlly cheap mods bc they supe up so easilly with those turbos. if u want an engine swap get a 240sx buy a nissan skyline engien wtih the rwd tranny and that drops right into the 240sx ir's a real easy swap but then your making 180hp out of the box and don't weight anything but also u got 300 torque and those engine with the stock block have made 1400 hp on the 101 octane racing fuel fastest street legal one i've seen put 700 to the wheels on pump gas then when he used racing octane he bumped the boost so it's straight from steet to race and he made 1100 on the race fuel
