97 B2600 Mazda Bravo/Ford Courier (after mod suggestions)

Hi,
I have got a 97 Bravo/Courier Crew Cab 4x4 (12v 2.6L 4cyl G6). It needs a new timing chain and the engine is getting a bit tired, so I am going to pull the engine out to make it easier to work on. I am going to rebuild the engine while it is out.

I am wanting to know what sort of mods I can do to the engine to make it better for towing.

Cheers

a good port job. not really big power in those motors. maybe add a turbo down the line but that's about it.
