Try typing what you want into Google and then put Ratsun at the end. If you know the title even better.

So I got the Pierce Manifolds 32/36 DGEV Weber conversion kit and I had a quick, newbie question about the intake.

 

There's a threaded hole on the intake manifold and I'm wondering what its for? First thought was for a bung for vacuum or something. I checked out the stock 520 intake manifold and theres a similar hole, but it just has a nut screwed into it. Any ideas? Letting my true new jack flag fly, go easy on me lol.

It's a vacuum hole if you need it for something (power brakes, PCV, etc). Otherwise, it's a hole that needs plugging.

Anyone know a good replacement/upgraded brake master cylinder? Looking to get a dual reservoir but open to options.

I don't know what kind of pedal performance you'd have with it on drum/drum, but I'm using 1978ish dual from a 280 for my disc/drum setup (see link to his stuff in first post).

If you are staying without a booster then you will need to take he shaft that connects to the brake pedal off of your original master cilynder and install it in a later model brake master cylinder from say a 620. 

 

Myself I used a 620 Pedestal, an 81 310 power booster, a 1980 720 master cylinder with a custom made shaft by Mike Klotz.  Remember my 520 is an automatic trans so no clutch pedal.

 

This is with a 280ZX master cylinder

Mike Klotz graciously made this in a much simpler form than my drawing!  Mike is a wizard when it comes to simplifying parts manufacture!

Fit like a glove the first time!  Mike nailed it!

Hey, @Charlie69. I think you lucked out going automatic... because the master and clutch cylinders are way too close to get a booster on the master without a complete rethink of the mounting. They both mount to the firewall maybe 2-3" apart :(

You are corect sir, and I mounted my master in the clutch hole to give myself more room between the brake and the gas.  In my 521 I always had problems when I was braking my 6E foot was also hitting the gas.
