Hey guys,

This is my first post here in the NA section and I was wondering if you could help. I have had conflicting reports about which oil filter bolts up to the neo RB25 and was after help. Is it a Z145a like my previous car or is it a z442?

I was told that after the 11th month 98 the 34 switches from 1 to the other but I need someone who owns one to tell me which one they use.

My car is a 1999 r34 GTV if this helps.

Z145A fits, but you ought to be running the smaller Z442 (or Nissan part# NI-15208-53J00).

Best thing to do, is goto Nissan, quote your VIN number and they'll look up what filter you need in their FAST catalogue software.

I always used the 145a....but recently someone bought a filter for me and got the smaller version, I can't see how something that tiny doesn't block quicker...in my opinion I like the ol' 145a as it's easier to grab when changing :P

Possibly.. but they ran Z145a prior to 11/98, then Z442 after - all on the same NEO motor. Maybe something else changes with the post 11/98 models... heard later models have GTR cams but I can't verify without opening mine up.

i have a r34 99 gtt i recently did a oil change according to specs book z422 the smaller filter is the correct one...... i opted for the z145a as said it seems to fit the same and is bigger easier to remove.....does anyone know the actual reason for goin the smaller filter??? my car also had a z145a when dealer/importer did oil change.......

i think the smaller filter prob has a diff filtration rating (ie diff micron size)

if it helps, my boss runs 3 cars in the AMCA series over here in WA (like super sedans - Holden 253's on custom body's) and they run methanol, around 11:1 comp, wild cams and they use the smallest oil filter i have ever seen...

The bigger the filter the less restriction through the filter obviously, on an NA its not so critical, but on all our race cars we try and get the biggest filter possible on them..., they are all essentially the same, there are a couple of different thread and oring sizes but essentially if it fits it will work... If you've got anything floating around internally that u need an oil filter to trap the type of filter your using is the least of your worries... your biggest concern is the cost of the rebuild...

      V37 Radiator removal

      Next, remove the upper and lower radiator hoses, both are held with a spring clamp. While you are under there, tackle the Auto Trans cooler lines.  Again both are held on with spring clamps, and as mentioned above you should cap them on the radiator side with an 8mm cap, and on the car side loop them with a length of 8mm pipe - this will stop you losing a dangerous amount of AT fluid during the rest of the job If you've been meaning to add a sender for AT trans temp, this is a great time to do it; put a sender fitting into the passenger side line as that is the inlet to the cooler/radiator.

      Next you need to remove the intake duct (as with pretty much every job on these cars), it is a series of clips you gently remove with a flat bladed screwdriver. They do get brittle with time and can break, and I have not found a decent quality aftermarket one that fits (they are all too soft or flimsy and don't last either) but the nissan ones are a couple of bucks each (ouch).  Once the clips are off (either 8 or 10, I didn't check) you lift the intake duct out and will see the reservoirs Undo the line into the radiator side cap (some bent needle nosed piers are awesome for spring clamps) and then remove the 4x 10m nuts that hold both in place.  I didn't get these pics, but remove the line under the radiator reservoir (spring clamp again) then remove that reservoir. Then you can get at the intake reservoir, same thing, spring clamp underneath then remove it. BTW This is a great time to put in a larger (+70%) combined reservoir that AMS makes..... https://www.amsperformance.com/product/q50-q60-red-alpha-coolant-expansion-tank/ They also make an Infiniti branded and part# version if that is your thing

      To drain the Intake Heat Exchanger, there is a crappy drain plug in front of the driver's side front tyre: You should use the largest headed phillips screwdriver you had, and in my case I needed vice grips on the hose above as the plug was tight (tighter than it needed to be, since it has an o-ring seal).  After you have a tray down and open the drain, open the intake heat exchanger reservoir cap (drivers side one) and you should get a couple of litres of coolant To get to the radiator, you need to remove the plastic engine undertray. It is held on with a series of 10mm headed bolts and some clips. For the radiator, there is another type of crappy drain (kind of like a plastic banjo bolt) and you should attach a length of hose to direct the stream of coolant per this pic (otherwise the coolant hits the rad support and goes everywhere). The drain is on the rear of the radiator on the driver's side and a bit hard to find. Put a big tray or bucket down (5l won't be enough) and slowly unscrew the fitting by hand. You only want to remove it far enough for coolant to flow, it you unscrew it right out the whole fitting and direction pipe will come off and you will get a coolant bath (yum!). Undo the radiator reservoir cap and it should empty about 8l

      So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You also need to drain the intake heat exchanger to remove the radiator so you will need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. 2 other tools that really help dealing with coolant lines and spring clamps are Bent Needle Nose pliers Hose pliers Between them they will reduce the frustration (and injury) potential by about 1000% Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic

      If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.
