In the process of riding up my car lol, am trying to get a decent looking oil cap. Some say they are fine to fit all RBs or even all Nissan, others like a stock GTR oil cap say rb20/25/26 but they won't fit a neo rb25. Is this due to the stock plastic engine cover or is there something else different?

My understanding is all Nissan oil caps are M32 x P3.5, including S1, S2 and Neo RB25's. 

What makes you think they are different?

Because there are differences in the caps.

Possibly other reasons too, but i belive it's the length of the threaded section.

As a sanity check, I verified a few popular brands like HKS, Nismo, Top Secret, Tomei, etc. and all have the same part# for S1, S2 or Neo. 

Are we sure they're not the same? Because I'm pretty sure they're the same...

Since I really take this oil cap science seriously I decided to take this even further...

I confirmed with Nissan EPC that both older and newer style nissan oil caps (15255-1P103 & 15255-1P110) fit all RB25's. I then realized I have three Nissan's with both of these caps in the driveway so I did what any grown man would do... I ran out and interchanged them. They all fit. 

Btw while on the topic, the newer caps (1P110) that I have on my Sentra and Rogue are garbage and can never be undone by hand. 

Cheers.

Cheers lol,  I think the Jun oil filter caps say they only fit rb20 and rb26.

Also saw on another site that a stock GTR cap didn't fit a neo. I only have a Neo r34 so can't really check for differences

Keep this up and I'll end up doing my doctoral dissertation on oil caps... "Oil cap variations and its adaptive consequences on society"

Now - from my measuring on Rb25det's, it seems there's thread room, so either cap would fit, but I didn't say 'won't fit", I said that there are differences.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
