There is no freaking way they cost $200. Part numbers in bound.

I bought mine from Greg V.

Part numbers on the first post under pictures.

what effect will this have in terms of how the oil squirts outa there...? like i know more oils is capable of coming out but how does this chaneg in pressure of the oil.....

thoose hole look ALOT bigger,....so ALOT more oils coming out of thoose bigger holes, wouldnt that lower oil pressure up there?

good find tho....

Okay, these are the partnumbers I was told was right at my Nissan Dealer

100NX GTi SR20DE (NX2000)


200$ for a pair

Gonna revisit now and see what the 03/13 bars cost.. My Nissan dealer here sucks big time...

Go to the link I have posted a few posts up. Greg V can probably send it to you for cheaper than that.

Or take a drill to your old ones, but be careful not to go any larger, there might be a significant drop in oil pressure if you go too large on the hole.

If it were me I'd stick with the small hole version. If used, inspect and get them ultrasonically cleaned and throw them back in. The holes were most likely enlarged by Nissan to prevent damage on neglected engines (sludge build up, excessive mileage between oil/filter changes, etc). I'd prefer higher oil pressure over knowing my cams will still be lubricated even if I don't change the oil all year.

Put oil in the highest part of the engine for safety. Win-win. I change these bars on any of my personal cars.

You can drill these out as well guys. I use a blue point carb jet drill on mine. You can do it by hand. Iirc it was like .040" that I used last time. Just pressurize the rail with some compressed air and you'll realize how much the small hole versions are holding back. You won't lose a bit of oil pressure either.

Anyone seen this video? You can see the oil spray bars in action!

Is it just me, or does it seem like the furthest away lobes are getting less oil? Or is it just because of low oil pressure?

Max speed of that electric motor 290RPM (saw it the other headless video). It's low on pressure because of low rpms (similar as cranking speed)
