I have this rb20det silver top head and noticed that on the fuel rail there are 2 fuel pressure regulator. Are they both fuel pressure regulators, or is one something else?

It is not letting me post any pictures, but here they are on my facebook page...lol

I can't see the pics. don't use facebook. but I assume you are talking about the fuel dampener and the fuel reg. fuel reg is on the end of the rail and the dampener is usually on a piece of hose? you'll see only one actually has a vacuum source from memory. that one is the fuel reg.

They both have vac lines. One was ran to the throttle body and the other is ran to the manifold. The one that is ran to the manifold is on the from of the motor. Is it needed or can it be trashed?

Also wondering this, the original RB20DET fuel rail I had I'm pretty sure only had one reg. The one I have now has 2 and they both seem to require a vacuum source, from the same point??

      High temp brake fluid?

      By GTSBoy · Posted

      Well, back in the day..... "race" fluids, which were essentially only really "high temp" fluids, used to absorb water more readily. So they really needed to be changed more often anyway. The coincidence of that being directly necessary along with it being what racers would do as a matter of course was just fine.

      Does the high temp fluid degrade any different over time compared to normal one? That's one thing I've always been wondering. Because a track car is going to get the fluid flushed probably way more often than every two years and will see less kilometers driven. I would think the requirements are different. I'm running Motul RBF 600 in mine. Was recommended by my mechanic before a trackday and I've stuck with it since. Hasn't seen the track since but I've kept buying and using it for servicing anyway.

      The brakes are all stock bar some DBA slotted discs and the EBC pads and braided lines. The car has brake ducts as standard but they're kinda pointed in the general direction of the brakes rather than really getting at the heat source. I guess I should hit it with an infra red thermometer after a session and see what they're at.  100%! Its just a curiosity more than anything. As I said, high temp brake fluid was such a track day rage back in the day. From people I speak to at the track and threads on here everybody has their own take on it but I'm not gonna scoff at spending a few more bucks.    OH, a quick side question - would you use brake fluid from an opened container even if the lid has been on? Eg, if you have a bottle that you opened last time you flushed, it's been tightly closed, is it still good?
