I have asked the question before with no avail on another forum. It may seem simple but I have looked this information up before with not much success, that's certain. So despite the trivial appearance and the ease of which you will spit out the reply, please note this information didn't come easy for some. X__X;;

I would like to know what I could get here in the USA to match for the RB25DET for Fuel Filter and Oil filter, as well, what weight oil should I be using for my engine?

The mods are:

HKS super intake

FMIC

Greddy BOV

3 inch super dragger exaust with decat

Stock Boost on Stock Turbo

----

Thanks in advance.

anything synthetic around 10/40 will be fine

fuel filter is a bit harder, but basically they are all the same a generic one ould be fine if you couldnt find a nissan dealer ove there. I'm sure that a nissan dealer with spare parts catalogue could help you out. oil filter is the same. you want a z145a or equivalent

Thanks a lot. So something like 10 weight 40? At the moment I have some 20 weight 50 laying around the house. I am sure that's not the stuff then right? Also, the VG30DETT from the 31 will work with the fuel / oil filter right?

Thanks a ton.

EDIT:

How many quarts does this RB25DET take with no mods, oil tanks or catches?

in the us your operating temps can be much lower than here in Australia. Its quite common on the BITOG forums based in the states to see new cars in the use use a 20wt oil. If your usage is only for street and short driving to the shops etc then I would be going a low wieght esp. in the cold sub zero temps. If its for track then you need something that will no thin out with high temps.

I qt is approx .9l. I use redline from the states which only comes in quarts.

The "W" doesn't mean "weight", it means "winter", and indicates that the oil will pour below 0C (32F). A 0W40 / 5W40 / 10W40 is likely to be your best bet. A 20W50 is too thick for startups (the 20 represents ability to provide lubrication from cold start).

For oil filters, etc, try something for the 300ZX.

FYI there are 3.79 litres in a US gallon.

I see. Winter then. But some people think it is cold as shit here or something. It isn't. Currently outside it is 96*F and it is like 40% humidity or some shit. QUITE HOT. It gets to around 20*F in the winter here which is a long shot off, it is still summer.

So you are telling me my absolute best bet is to use a 10W40 where I live? Because I don't want to keep changing around on this shit.

And that 4.3 litres is 4.5 quarts of oil. 4 and a half bottles of oil go into the RB25? Damn son... lol

I've run 0W45 and 10W50 in my R33, both went well. As said above, it's a matter of temperatures.

You say your temperature range is about 100°F down to 20°F. Which is like 37°C - -7°C. Compared to most parts of Australia, that's pretty cool. Here in Perth, Western Australia we're looking at a range of 45°C - 0°C which works out to be like 113-32°F. But in approximate terms, the temperatures are pretty close.

So as suggested above, go with something that has a light cold weight (small first number). 0W40 or 10W50 should be fine (or anything pretty close to that). Turbo cars can be a little fussy when it comes to engine oil, so it's best to spend a little extra and get it right the first time. WHile the 20W50 you have there may work, why not just spend the little bit extra and get the right stuff?

For the oil filter, I go with a Ryco Z145A and then fuel filter was Ryco Z200. I'm sure you'll ahve similar parts available at your local auto-store.

    • Gday, Due to not finding much up to date info on this topic I thought I'd make a thread to get peoples latest opinions/recommendations. Background info -  I've got a S1.5 R33 GTST as a fun project car, mainly for street use and occasional drag strip, apart from all the cosmetic things I'll be doing a full rebuild of the engine with forged internals. Since it'll be getting new cams (kelford) and springs to match I thought I might as well get new lifters and valves while I'm at it, the dash says 160k KMs but the engine seems pretty tired, compression measures about 130psi across all cylinders so I'd like to freshen everything up. This is where I'm tempted to just fork out the extra and go solid lifters while it's all apart, aiming for 400-450kw atw with a flex tune. Assuming all supporting mods (oiling, fuel and all bolt ons) with a lightly ported head and turbo to match (yet to make a decision possibly gtx3582r or similar from Hypergear) I've seen the Tomei kits with just the buckets getting around, Supertech sells most things - Supertech High Performance Cam Followers | Trusted Racing Cam Followers Questions -  Has anyone found the Hydraulic lifters to limit them at this power level? Is it usually found that you can just clean the stock lifters and find they work fine?  Does going solid lifters save any headaches/issues with hydraulic lifters in the future? Any recommendations on other things that will need to be replaced, I know I'll need to get the solid profile cams but can you use the same type of valves and springs/retainers and is it recommended to change the guides and stem seals?    Summary -  Basically looking for pros/cons and wanna know if I'll actually need the extra RPMs from solid lifters or it'll just be bragging rights to say it ReVs OvEr 8000 Cheers
    • Ha ha ha, this stuff they had was installing Toshiba PLCs that were made some time in the 1990s, and they were replacing GEM80 PLCs. To let those two talk (staged upgrade along a ~1.2km long building that was split into 4 sections), was a bunch of WinXP machines running Java gateways... There was no way to put something like ProfiSafe in... Most of the HMI machines were WinXP, with Java program, with a custom button board emulating a keyboard... About the only buttons in the operator stations that went direct to the PLCs was the eStop. There was some interesting design stuff in that place...
    • Stock bypass valves are good for plenty of boost.
    • Check for fuel flow out of the outlet end of the rail. Check for spark. Try to start with aerostart (or pressure can brake cleaner or similar solvent in a car) prayed in through TB. If you have fuel and you have spark and it will fire on substitute fuel, then seriously suspect that E85 sitting for ages in your fuel system has destroyed something and put it in your injectors.
    • Nissan stock oil pressure is typically about 1 bar at 1000 rpm plus about 1 bar per thousand revs on top.
