I'l go with Quinn on this one. Get it on the road & attend some Datsun events. Have a look at what others have done & see if you like it.

Next, check the downside of that mod or alteration. How hard is it to do? What costs are involved? Is it legal? Is it safe? Is the car still driveable? Can you AFFORD it?
Dumping the suspension in the weeds & fitting a full race V6 is nice, but if it won't clear a low speed bump, & the engine it too hairy to drive through town, then the 2 squillion dollars spent on it is not a good investment.

Look hard at the others, even go for a ride in them, but learn from the mistakes of others, & not your own.
