I've read a few Tii to Na swap threads and I'm about to do my first swap. But before I start buying anything I had a few questions.

I have a S5 and I'm thinking of buying a motor form JDM that comes with ECU.



1. If I get a S4 motor, does the Turbo trans, drive shaft, and rear end that I buy have to be S4 also?

2. Will the motor still line up with my S5 motor mounts?

3. The only extra "necessary" parts to complete swap are:

N370 pressure sensor
TII Throttle Cable
Drive Shaft
Rear End
Transmission
Fuel Pump
Hood

anything I left out?

Any feedback would be much appreciated.

Keep it simple. If you collect all the parts you need it should only take about 40 hrs. of labor to complete, even for a first timer.

Get an S5 Engine, TII trans, TII hood, TII drive shaft, TII rear diff & half shafts, N370 ECU (N374's are hit & miss in USDM cars), N370 AFM, N370 Pressure Sensor.

Keep the engine S5 and the ECU S5 and it is fairly simple to complete. You can use your NA harness to wire your TII engine (2 of the solenoids you cut off and one goes to the knock sensor and one goes to the boost soleniod).

Unclip the wiring harness from the ecu, and 2-3 harness clips up under the dash and push it out, leave it attached to the engine when you pull it, then label everything as you remove it.

I've herd the drive shaft is different lengths from S4 to S5. Should I make sure to stay all S5 if possible?
