Actually, I think he just said "computers" not "CPU upgrade". A CPU upgrade on the E21 is not possible, due to the fact that there isn't a CPU to begin with. Yes, you can add a computer, but I would recommend either a straight swap from an E30 318i and bringing over all the EFI, or, if you want a more tunable project, bring over half of the E30 318i system and go Megasquirt.

There isn't much in the way of bolt-on engine performance upgrades for these cars. The world is your when you consider, internals, upgrading to a M20 6cyl, etc.

If you want to make the car more fun to drive, focus on the suspension, strut bars, urethane bushings, urethane subframe mounts, etc.
