: Holy shit. All this over a Ford V8?
Sounds like a deuce project, dude. That thing would really be able to haul some ass, but you're gonna be looking at more upgrades than just the diff. Transmission, driveaxles, engine mounts, engine computer management, a lot of things that will need to be upgraded, changed, rearranged, experimented with, etc.
Expect a lot of downtime to get this done.
On the whole though, I'd want to see this. Upgrade your front suspension (the Ford block will weigh a LOT more than the 1.8L) and let's see what "Euro purists" get their asses eaten off by this thing. You'll be feeding them their asses on a silver platter. Don't get me wrong, when and if I can, I like to keep my car close to its original Euro specs, but c'mon dude! He got the car as a GIFT. It's not like he's in the hole for it. Would make an awesome machine if it works.
The Deuce is right. Get your head outta there and smell some fresh air.
