i know alot of people have probably ask this but i have a 87 s4 n/a i want to swap a TII in it what all will i need to do i heard that the motor will drop right in and the wires will all match up all i will have to do is wire in the knock sensor into the ecu please help i have no ride right now well atleast its about to blow up thanks

 

IM ALSO DOING THE SAME SWAP I HAVE AN 86 YOU WILL NEED THE T2 ECU AS WELL SO THAT THE COMPUTER CAN READ THE SENSORS MAKE SURE THAT THE WIRE HARNESS IS THE CORRECT 87 T2 HARNESS, AND YOU WILL ALSO NEED TO CHANGE YOUR FUEL PUMP TO THE T2 FUEL PUMP AS WELL IF YOU HAVE ANY MORE QUESTIONS ON THIS EMAIL ME deveris_w@yahoo.com I WILL GIVE ANY INFO THAT YOU NEED MINES IS ALMOST DONE

 

so u wont need the drivetrain and all that stuff

 

for the t2 no if you have an 86 and your doing a turbo swap you dont have to change your rear end mazda trix sales a driveshaft for its 300 also the only thing you would have to change is the wire harness the ecu the pressure sensor and you will need a knock control box its not that much to do but you do have to consider that because ts going to be a turbo it has to match up for instance the ecu has to be changed because it has to read the boost and all that so you dont need to change a lot of things
