are you switching engines or just parts from the t2 engine on to the n/a engine if your switching engines the best way is to get basically all the drivetrain rear axle drive shaft tranny t2 ecu t2 wiring harness so on so on someone add the other parts i left out

you can actually use your n/a harness..you will need a turbo 2 pressure sensor, add this and everything 91mazdarx7 listed and you will be good to go, you might need a downpipe if you dont get a front clip

good luck

i did the swap on my 90 gxl. all you really need for a running car is the motor. you can use your ecu, harness and pressure sensor from the n/a. you should go ahead and get the tranny, driveshaft and rear end but they arent neccesary. and yes you will need the trottle cable and TII hood.

not sure about the ecu, but definetly going to need a turbo pressure sensor because the n/a is not made to read boost, and it will also need to be a s4 or s5 depends on the motor
