im trying to get a 13b-re swap to run eventually i'll get a standlone but i just want it to run and thats it what ecu can i use that will be cheap.
its in a 1991 n/a i have the 13b-re ecu will that run it? i read a turboII ecu will also run it but which one a s4 or s5?

 

series 5.

since its more similar to it.

install OMP and stock t2 turbo and you can drive it around.

the re ecu will not run since they only came in automatic.

 

You will also need the S5 TII boost sensor.

If you wanted to go really cheap you could keep it N/A and drive around on the S5 N/A computer, it would run a little rich on the cosmo injectors

The S4 ECU will not plug into your harnesses
