hi,i own a sa22 that runs with fc engine 13BT.the problem is that i bought it this way and i think that the last owner(he is a mechanic) has mixed up parts to make it work.i think the block is from s5 and the rest from s4 engine.the funny is that he uses N322 ecu,especially N322 18 881C that i think is a euro-spec NON-TURBO-ECU.he had the distributor on too.it's a mystery how it works and i have to tell you that it cicks ***.i'm going to change the coils first and after that i'm going to change the ecu.what will i need for that?engine harness?what else?thank you

 

Hey Nik...
The even stranger thing is that your car was runing with no oxygen sensor man!!!!


MAybe you should post this in the ECU section of the forum...

 

Well, it's not that strange to use a 13BT in a SA with a dizzy. By taking away the CAS, it's possible to use a fuel only ECU (the Euro FC NA one) but of course it's a serious question what fuel air ratio will do under boost. If there's a rising rate FPR (real rising rate, not one to one) and a good fuel pump, it's possible to run it this way, but I don't see why you'd try...
If you'll install a TII ECU, you'll need to study the wiring diagram very well. You'll need to get coils, CAS, ECU, loom, but maybe some sensors aswell. You should try to get some FC specialist (Higgi???) to tell you the difference between NA and TII; as you might need TII AFM etc...
