Engine build idea

[Oltorf]

This is kind of a "shower thoughts" kind of idea. I'm not seriously considering doing it, but it's fun to think about. I know a lot of people will say "just do an LS" or "it's not worth it." Thanks, but that's not much fun.

So I wanted FI of some kind in my 4.8iS. No one makes a kit, but new N63 engines have a pretty rad hot-V twin turbo set-up - but that would mean using a smaller engine. I wonder if the heads and up from a N63 engine could be swapped into the 4.8L. Stroke is the same, bore is a bit bigger on the 4.8. Rods from the N63 could be used and I'd have to find some forged piston heads that would give the same compression ratio.

I don't know how much different the blocks are. I'm hoping they're mostly the same, otherwise this engine build would be pointless.

There are a bunch of other things to consider - exhaust routing, transmission and transfer case, etc, but this is all I was worried about so far.

Twin turbo factory setup 4.8 would be pretty pretty pretty pretty cool.
