The guys at race car engineering recommend -6 fuel line to rail, -8 return to surge and even -10 surge overflow to tank.
All in the name of reducing pressure where you don't want it. Especially when using twin pumps that can handle some big flow.
Aeroflow are a direct copy of the Holley pumps and have the same colour coding for the pumps. The red and blue models aren't methanol compatible but the black is. The black is 140gph.
Carter lift pumps aren't e85 compatible either. I've just gone through this myself and ended up with the aeroflow black since anything better was a substantial increase in price.
I needed this the other day. That part number is correct and only comes in a twin pack. Holden said that that part was obsolete in 2007 but Nissan recognized it only when they paired it up with the Patrol rb30. I thought I didn't need both threads but I ended up using the other one in my remote filter mount to keep it RB specs when buying a new filter and not the universal 3/4 type.
Is there a reason why the rear head drain setups always seem to go to the turbo side of the sump? I'm just about to weld on my -10 fitting for the head return and the intake side seems more logical due to less heat and the fact that the sump baffle isn't in the way of the high position on the sump.
If anybody encounters this issue in the future, just tap a 12mm thread through the sleeve, put a bolt in and then pull it out with some pliers.
I just had great success this and now I'll just grab that cheap replacement part off nissan.
I'll vacuum the hell out of it and I currently have the sump off so I'll make sure no dwarf gets anywhere. I had a similar experience with installing a rear head drain the other week.
It's a track only drift car so it will have regular fluid/filter changes.
Thanks for your help guys.
The previous owner was a bell end. I bought the rb 25/30 all excited then I got home after the 2 hour drive and found rust and leaves all through it. I have removed the head and rebuilt based on these shonky findings.
I think I might try tapping a thread through the shit and screwing a bolt in there. I won't run the relief valve.
It's a n/a rb30 series 2 block and it's an RB30DET now. I bought a half done motor and pretty much have pulled everything apart over months and rebuilding it. I figured I'd bugger off the bulky heat transfer and add an oil cooler and remote mount. This was the first time I removed it.
Hey all
I removed the heat transfer/oil filter block from my RB30 and found this inside. It's fairly solid and I'm wondering what the hell it is? Either something foreign or a smashed in factory something. Any ideas would be appreciated.
