R33: 2 Brake Fluid Reservoirs?

There is a small reservoir on the left hand side and towards the back of the R33 engine bay that says its for brake fluid.

The adjacent larger brake reservoir specifies DOT 3 brake fluid only on the cap. But the smaller reservoir doesn't specify any DOT standard on the cap.

Would I put the same brake fluid in there as the larger adjacent brake fluid reservoir?

Why are there 2 brake fluid reservoirs anyway?

Can I use the same brake fluid for the clutch as in the brake fluid reservoir?

What brand would you recommend? It says use only DOT 3 on the brake reservoir.

See link below for pic of reservoir in question.

Whatever is cheap, it can all be mixed as each DOT specification is chemically compatible. As long as you don't get DOT5 which is silicone based, DOT4 or DOT5.1 is what you want and both superior to DOT3 (I doubt you could find DOT3 anyway)

If you are chewing through brake fluid, then you might have a leak somewhere in the brake lines, pinhole leak in a rubber hose for example.

I thought my clutch fluid reservoir was empty but it turns out the fluid in there is really translucent. Is that normal? It's a different colour to that of the brake fluid.

You use the brakes more than the clutch, brake fluid can get up to and perhaps beyond 250C under heavy conditions on the road (easily 300+ at the track) as it absorbs heat from the calipers, discs, and pads whereas clutch fluid just acts actuates the engagement of the clutch. So that's why clutch fluid stays the same color, whereas brake fluid will blacken over time.

      OEM Soko: Japanese business supplying Automotive items from Japan - Freebie inside!

      By Rezz · Posted

      We have some genuine Japanese legally decommissioned car number plates now in stock 🙂 Add some legitimately obtained JDM style to your Skyline or other Japanese model, or simply as a garage/man cave decoration! About the 40mm hole: The Ministry of Land, Infrastructure & Transport in Japan recognised the popularity of keeping decommissioned plates among car enthusiasts and came up with a method to "destroy" (or render them unusable for street use) while still retaining their collectable/usable value for display etc.  We have 40mm hole covers available to cover the hole nicely with a Sakura motif, which are also available in white in (very!) limited quantities, however they frequently sell out. Please let me know if you're wanting one or more of these and I'll check availability. The Sakura motif covers are more common. https://www.oemsoko.co.jp/products/genuine-decommissioned-japanese-vehicle-number-plate-set-su-7515 https://www.oemsoko.co.jp/products/genuine-decommissioned-japanese-vehicle-number-plate-set https://www.oemsoko.co.jp/products/genuine-japanese-vehicle-number-plate-400mm-hole-cover *Please note that we can't obtain particular number or area name (eg: "Gunma 500 Fu ・86") if requested. All plates are provided as they become available after decommissioning.

      Ah, fair enough. For the IAT, I'm using a legit GM sensor that was used on the car prior to my current build. I'll get another wideband and IAT ordered and follow up when they show up. Thanks for the help.

      You shouldn't need to massively fatten up the mixtures for cold conditions. For one thing - 0°C is not that cold. For another, the Haltech will be using the IAT sensor to tell it how dense the air air, and calculate the correct amount of fuelling. Then the cold start enrichment is added as a % on top of that, so it should scale with the main fuelling. You might also doubt the IAT sensor at this time. You're not using one from an RB26 are you? Using a nice Bosch sensor or similar? Happens. Some wideband units take great pleasure in killing their sensors. Put another wideband in the tailpipe and compare. Or just swap the sensor to a brand new one and see.

      Oh, my misunderstand. When the car was running, it sounded ok, but if I gave it any gas it wanted to die but caught itself afterwards. It's very different from how it was a couple months ago when it was warmer outside. The logs show that the AFRs are better during, what I assume, is warmup enrichment. Because it's cold, and air is more dense, should I work on the enrichment bit?

      Rb20e and RB20DET parts

      By A31Skyline · Posted

      yess of course im not using 2nd hand parts from my spare engine, but the place where i live is hard to find parts for the RB20DET ,but for the RB20E is everywhere including new ones and a lot cheaper ,because for the RB20DET you have to order it overseas to get one and it cost a lot of money 3x the price to be exact. so i ask this topic because if i can use the new ones but for RB20E is it compatible or not. if not im screwed haha, not totally screwed but i have to save a lot of money first before i can begin repairing my engine, thanks for the information before.
