Jeep XJ time-lapse engine rebuild, 4.0L STROKED to 4.6L | Redline Rebuild

Our 1993 Jeep Cherokee Sport needed its tired engine rebuilt, so we figured why not give it a decent upgrade while we're at it? Of course, we wouldn't miss the opportunity to shoot time-lapse video of every step along the way and hit you with another amazing addition to our Redline Rebuild series!

So, what was he doing with the piston rings before he put them on the pistons?

How much would this kind of 4.0L engine treatment cost. Total Parts and Labor expense. Estimate s fine.

I am the first and only owner of a pristine 2004 Jeep Wrangler Unlimited (2-Door) 4.0L. It urrently has only 28,000 original miles. If we wanted to increase the engine performance would it be more cost effective to install a turbo-charger and headers or perform a similar rebuild to STROKE it to 4.6L?

What other crazy performance options are there? V8 Swap, Turbo-Diesel Swap, Electrification, etc... What is the most cost effective? Thanks for any input.
