Point me in the right direction please

I've been hunting for hours (but I'm no detective) to find a thread or site that talks about swapping a Renix for a HO all the way.
I've found plenty for swapping the engine and keeping the renix electronics but I've got a '91 and a '88 sitting side by side and I'd like to get the whole HO in my '88.
Thanks.

After reading for a few more hours I can't find anyone who has done a full swap. Is there not that much gain by going to HO electronics and computer or is the majority of the gain from the head, intake and TB?
