I have Q45/MPV (older version) parts on the way and there seem to be two 240sx brake line options - one for one for the Nissan Z caliper swap (on a 240sx), and the regular 240SX SS OE replacement. Which would be better for me?

Guys working on a front brake conversion for the MK2 that will be more affordable. Almost there. Will fit 15" and bigger wheels. There may be some limitations though.
Here is a sneak peek at it. The cardboard is temporary and is there for a reason, I'll explain later.

I should have everything worked out by the new year. Just waiting for parts, holidays to start and exams to finish.
Once completed I will post the conversion on the web so anyone can do it themselves.

I'm not sure that the Z32/MPV setup will clear 15" wheels since I've never had 15s. Running the rotors over hubs will also increase your front track width due to the thickness of the rotor hat between hub and wheel (approx 10mm on each side).
The hardest part of upgrading to the Z32 calipers is finding a machine shop to turn the hubs down, and drilling the 4-lug holes in the MPV rotors. After that you will have a front brake set-up that is reliable, easy to install and change pads, and strong enough to overpower most tires (I can lock 255s with medium-hard pedal effort). I'd recommend the alloy calipers that accommodate 30mm rotors (mine are remans from Autozone), and a set of 240sx braided steel lines. I run cheap rotors because I replace them every race (actually, the last race we put 22 hours on a set of cheap rotors with so little wear that one minimal pass of resurfacing made them brand new again).
