ok like the title says what needs to be done,off the top of my head I can see.
pressure sensor
face plate
cas
tps sensor
engine harness
ecu
?????, what else am I missing?

 

You're missing aspirin.

You're gonna need it once you realize that the S5 TII ecu doesn't plug into the car's body harness.

 

Assuming you're putting an S5 engine into an S4 (since your thread title is pretty much useless), you save yourself a massive wiring headache by leaving the S4 electrics exactly as they are and adapting the S5 engine to suit. If you want more info, explain what you're doing a little clearer...

 

He's not going to be able to use the S4 wiring harnes with the S5 because of the oil metering pump. He can't even eliminate because the S5 stock ECU needs it. Unless he use the S4 front cover and S4 ecu.

 

Did you miss where I said leave the S4 electrics as they are?

 

s4t2 motor is going in a s5na body,sorry i thought i made it clear my fault.

 

BA-ZING!

ok from what I've been told everything that I stated was correct.Basically tear the block down bear and add all of the s5 stuff electronics included.When I start on this i will post.

 

dotn waste your time. run a standalone. and premix if you are having omp issues

 

I see. Your going to put the series five front cover on the series four to take care of the omp problem.

The cas are the same. Leave alone. Matters not.

TPS means your going to have to put the series five throttle body on the series four.

Leave the series five EM harness in the car. No series four electrical allowed for obvious reasons.

Use series five ECU. No series four electrical allowed for obvious reasons.

Seems to me the vacuum rack of the series four should stay in place. I've never seen a series five turbo ( don't roll your eyes upwards, please) but I think for sure the vacuum arrangement is too different. Guessing. Hmm. Maybe you should read that rotary resurrection site rather than this.

 

Will the S5 n/a ecu run the S4 T2 motor? This post made it seem that way so I wanted to eliminate confusion
