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.

or for fitting so you can check your vacuum when tuning carb

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).

Thanks! The link didn't go anywhere though, just looped back to this forum. Charlie you got the link?

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.

Makes me wish I hadn't changed to a 720 chassis.  Damn fine Machining!!!

Actually I'm looking for the hold down clamp that holds the distributor against the motor where you set the timing. Here's a picture Wayno posted for me:

Did you ever find a suitable bracket? I seem to have accidently thrown mine out while cleaning my garage.

I bought an old reconditioned Lucas MG distributer instead that has parts readily available and fits the stock mount.

Yes, that is the part I was looking for, as well as the piece that attaches to the block. After doing some research and 320 Newb's comment, I found that I can put an electronic distributor from a Midget in it.

Hey guys ! Anyone replaced their radiator for a J13 520 or even J15 ?  Looking for a replacement but cant find anything ''exact fit''. What is the best alternative ? A 521 with 1.6 l will fit  ?

The l16 radiator might not work.... 

If the pic I saw of a 520 radiator is correct then the inlet and outlet is on the wrong sides....

Yes true ! Maybe the A12 engine rad would fit. It seems to be the good side for inlet/outlets....but they are 28 mm vs 35 mm on the J13. I guess I could get some reducers to adapt !

How bad is your radiator......

Another option might be bringing it to a radiator shop and have it recored....
