hmm. What to do? S4 motor/ S5 motor. What EFI management?
So i got an '87 Turbo II with a blown motor. Im not sure exactly what it is but that doesnt matter. Its got a big streetport. Like it brapped hard. Lots of supporting mods...
I also have an imported S5 Turbo motor sitting in my garage. Very good compression. Seems to be a good motor. No wiring harness.
How hard is the S5 motor swap? I want to rebuild the S4 but would it be worth is to swap the wiring and put the S5 in? I want a different engine management... Haltech, Apexi PFC, Motec, ect. Not sure what i should buy. Looking to run big turbo and big FMIC with full V mount with about 450hp ish. Im kinda on a budget built but i got lots of time to save money. Most of the stuff will be fabricated by me and my father and the engine/s will be rebuilt by me.
Whats better in the long run? This is my drift car. Not a street car. I want to port the S5 motor later down the road if i go that route. Just looking to see the troubles of the S5 swap in an S4.

The only things to be aware of are the alternator, if you use the S5 it will be a rewire job. Or you can run the S4.
You will want to run the stock wiring for the wiper motor and the cruise control if you are going to use it.
You may need to do something about the stock gauges as well, unless you are going to run aftermarket gauges.
