Reviving my old thread.
I'm still in the just thinking about it stage. But here's what I think could work. Take a SC 3000 Series II from a FWD along with it's wiring harness. Get a supercharger from a Holden in Australia since it has a inlet that wraps back around to the front which should eliminate firewall clearance issues. Keep my 5spd but dump the TOD transfer case for an earlier Amigo one per Buffy's setup.
I was reading an old thread in a different forum about the guy in AZ that swapped one into an Amigo. I'm sure a few of you know him. His build was very custom machine shop and welding intensive though. My preference would be to use as many off the shelf, or more appropriately, out of the junkyard parts. Borrowing parts of the Camaro RWD setup such as headers and accessory brackets.
I have 170k on my 3.5 now and no real problems except the usual oil usage. I'm just looking forward. At some point the engine will go and then what? Another 3.5 or a 3.2? Not a great platform with dwindling support, few performance options, and no tuning options. V8 options are a possibility, the easiest probably being the Northstar or Shortstar. This wouldn't be a bad way to go but head gasket problems on these are common and very expensive. I just like the idea of bulletproof SC V6 with lots of support and performance options.
There's no 'I' in denial.
