Yes, the S5 turbo is superior all around to the S4 turbo with a functional twin scroll system. https://www.rx7club.com/showpost.php...55&postcount=2
And in your case, you would need an S4 ECU and twin scroll solenoid to control that actuator. An S4 turbo without the twin scroll system has even worse low-end.

The engine is clearly using S5 electronics, and you said you have an S5 ECU, so I don't see why you don't just get an S5 boost sensor. That seems to be the only part out of place. Unless this is an S4 car, and nothing has been rewired to accommodate all these S5 parts?
If this is an S5 car, there's definitely no point in trying to use S4 electronics.
If this is an S4 car, you can use an S5 ECU + S5 sensors, and rewire the harness.
OR
If this is an S4 car, you can use an S4 TB, S4 front cover & OMP, S4 ECU + S4 sensors, and buy an S4 emissions harness.

The engine got swapped to a toyota starlet so I dont really know anything more than the harness being s5 and the ecu being s5 as well.
When I was testing the swap some wires melted and made a short circuit and my ecu looks to be damaged(grounded), I found on ebay this s4 ecu + s4 harness and I was wondering if I could replace my damaged s5 ecu + s5 harness with the s4 stuff on ebay.

Yes, but plenty of people also choose to do it the hard way. Rewiring is possible. Making an S5 ECU work properly with an S4 boost sensor and/or other S4 sensors? Not so much.
What year is this car? Maybe you mentioned it somewhere above, and I just don't see it. Is is S4 or S5?
