just wanted to know if there is a different between a tt or non-t 300zx brake master cylinder. i am planing to do an upgrade on my brakes

There are three different models made throughout the years and offered in various configurations. 15/16", 1", and 17/16". They vary based on engine, year, and transmission, but no one has nailed down the exact changeover for each model.

No...there is no difference between TT and NA

which one is better among the three models? what are those "15/16", 1", and 17/16" stand for?

Well, I would assume they mean inches, as in the size of the cylinder bore, like any other master cylinder is measured. But I'm not a rocket scientist.

its hard to say which one is best...for a few reasons. You're gonna have to search to get the whole pic but a quick summary, as best as I can remember:

In Japan S14 K's came with 30mm iron front calipers and the same rear calipers as the US. This is equiv to doing just 300zx brakes on an s14. They used 15/16 master cylinder.

The brake booster between manual and automatic 240's is different. different master cylinders have different "knee" points, which is the point where the brake bias split kicks in.

So which MC you need varies depending which combo of brakes you have, which booster you have, and which knee point you want.
If you have a manual car, i'd say go with 17/16 and probably be happy.
for an auto i might go with a 1".

larger master cyclinder moves more fluid for an equal amount of pedal movement. so if you pick too small of an MC then it will take a lot of pedal to fully engage the brakes. if you pick too large the range of pedal movement between barely braking and full will be small.

good luck
