So found a cheap S4 NA engine to use while i finish building my turbo engine and get the papers to get it street legal.

Thought it was a fairly straight forward job, and that i would just need to change the ECU and pressure sensor, but it looks like i need to change my wiring loom :/

The NA engine came from a 1986 NA, it came without the distributor cap or coil.

What do i need to do? change the wiring loom? or is there another way?

 

ecu harness, pressure sensor, maf needs to be changed and the wiring to to guages might be different since the t2 has a lil boost gauge.

 

Can i change the distributor for a CAS in order to use my T2 coils?

 

So i have read a bit, and since my car already has a wiring loom for the "standard" S4 engines, i should just need CAS, NA S4 ECU and maby a NA S4 MAF if it's different from the T2.

Wich "Nxx" numbers are on the parts i need?

 

S4 N/A : N numbers are N326 or 327.
