I have a 99 Sahara . What engine will fit in it. For example 97, 98, 2000 from other jeeps. I'm looking at buying one and rebuilding it over the winter. Just not sure it the engines are all the same size.

Any TJ or WJ 4.0L block will work. I don't know about the prices where you are, but around here a good rebuildable block will run 200.00 or less.

Are you going to rebuild it stock? You can stroke it cheap and easy. You will be happy.

I was going to rebuild it stock.

You could give yourself a little more bang if you dropped in 4.2 crank and rods. The numbers vary but I've built 5 basic ones like that and the average is 30-40 HP and roughly 60-70 foot pounds torque.
Look for the snub nosed crank for a serpentine belt system.

Why not bore it out .030 over, add a mild cam and 4.2 crank and rods? You will already have it torn down it would be the perfect time.

Because this is my first engine

Everything everyone has recommended would be in place of stock. For example if you are going to replace the camshaft and lifters, why not put a slightly hotter/more aggressive cam in its place? If you have to bore it out (bad cylinder walls) why not stroker pistons and rods?
If you are trying to keep cost down and can get by with just a hone and rering you could still go with a better cam and pick up a little more power.
Just take your time and think things through and you'll be fine.

I will. This is going to be my winter project. I'm looking at a few engines today. If I pick one up ill rebuild it over the winter and then replace it on my jeep. I'll take my jeeps current engine and rebuild that too.
