Fight? ... Nah, just a little spirited discussion between a couple of site-mates over our favorite Datsuns. Fighting includes swear words & name calling, & i do not to stoop to that.

Now,... if you want to do a CA instalation in a 1000, then have a think about the CA16DE. On the upside is the lower cost of these things & they are every bit as good as their bigger brethren, but should be legal in a 1000.

You can very likely buy a whole EXA, & drive it home for less than the cost of the "18" This way you get all the bits you need like computer, harness, fuel tank pump & a zillion other small bits & pieces to enable a good job to be a great one.
The end result will still be a really good performing car.

Sleep on it.
