S5 turbo engine swap to S4
I've been wanting to go turbo for so long now because my engine finally gave out.
I have an 88 S4 GXL RX7 N/A. I was wondering if I can swap an S5 turbo engine into S4. What is needed? I saw an engine that was being sold and it has:
-engine wiring
-5 speed tranny
-ecu
-power steering pump
-starter
-ac compressor
-alternator
-exhaust manifold
-intake manifold
-injectors
-clutch
-flywheel
-pressure plates
-turbo
-intercooler
these are just stock and not have been modified.
What else would I need if I wanted to do the swap?

It'll be easiest to replace all the S5 engine electronics with S4 parts and use your existing harness and an S4 TII ECU. The wiring is totally different between S4s and S5s. Or you could get a standalone ECU and be happy now and have plenty of room to grow when you want more power
