If you spent half of that on a 4G63 it would be a brutal monster. Would be a much simpler upgrade and finding a manual 5 speed to bolt it up to would be just as straight forward. My main concern with the V8 install would be weight distribution - that's a whole lot of extra metal to hang over your front cross member. I'd be wondering if it would require heavier rate springs/suspension upgrades.
