Well if it is a 1998 it would be a Neo correct?

So it is most likely from a R34 GTT or from a C34 Stagea. Pretty sure if you find the serial number on the block and do a search for it in Nissan FAST or something it would tell you.

Here is a picture of a Neo without the big plastic Neo cover on it:

As you can see the main differences are the throttle body, the timing belt cover, oil cap is recessed, plastic crank angle sensor etc.

Hey guys, for anyone wondering, check out my engine number register:

HERE

Have just added a submission field that will go to a database for me to screen and add. So please submit your numbers, if you don't know your year & month, pm me i can help.

Cheers

As for filter, Z145A VS. Z442 are the same thread, sealing O-ring surface size.

Both from memory are around the 26-27 micron.

Z145A has an anti drain back valve but no pressure relief if it gets blocked etc.

Z442 Has pressure relief built into filter and anti drain back.

My opinion of it is that, the Z442 on later RB's is used because recomended oil change intervalls are shorter, so smaller filter satisfy those requirements.

I have used both on all RB's they are fully interchangeable... just smaller, oil cooler housing the smae etc. putting it in a nutshell "they blocks up sooner if you don't reguarly change your oil". but in normal use you won't ever have that problem.

Cheers

    • Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
    • Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.
    • also possibly backed up to my filler and shat down it! 🤣
    • Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
