John, can you explain / describe the change regarding handling with an LSD ,

or is this more of a racetrack need than regular weekend dry street tooling around ?

Toss-up with '80 JDM head assembly swap and 2 1/4" exhaust, but it's summer so I'd say cooling system upgrades; essential if you ever drive fast uphill where temps get to 115F and above. Not one thing though.

 

Metal head gasket, aluminum 3-row radiator, oil cooler, Nissan thermostat, fan shroud, BRE spoiler.

Dual exhaust system. Effective as far as performance- who knows, but very effective as producing the most beautiful exhaust sound I've owned in a car.

I am finding all of these suggestion far too practical, serious, and sensible. My suggestion is a flux capacitor, time circuit, lightning rod or a Mr. fusion; which ever seems like more fun to you.

If you're just tooling around then you don't care about handling.  Driving at 4/10ths of a car's ability doesn't require good handling.
