Engine swap buying advice

I was poking around ebay and looking at some of their complete engine swaps. I saw 2 that caught my eye. I want to know if these are a good deal.

I own an 88 gxl NA. I plan on getting a turbo 2 hood.

Both are S5s

I understand that some work needs to be done to convert the S5 wiring to the S4 dash panel. But if I read everything correctly (very possible I missed something) Both of these engines have everything needed for a pretty much straight drop in, minus a drive shaft to connect to the rear diff and any mods to the wiring for the instrument panel.

Advice?

So you''re using all s5 electronics. In that case you are going to have to get the other harness that plugs into the ecu also, or at least the pigtail so you can wire the s4 harness to it.

I put a s5 in my s4. Granted I used all s4 electronics. Either way though save yourself a lot of time and frustration and get an s4 motor. I regret getting the s5. It's really not worth the extra 20 hp.
