I've done some searching on this site and google etc, Im still stressing because i believed my engine to be a series 1 RB25det (as it has the ignitor ontop of cam cover) BUT today i bought an oil filter from a workshop, he gave me the wrong filter & upon returning i asked for the same filter currently on my car (Z442) the guy said they are for 1998+ RB25DET's only..

I've already bought cams for a series 1 RB25 yet to be fitted.

can anyone confirm this?

the wrong oil filter could have been put on at any time in the past.....z224 is a straight replacement that is a little smaller so maybe a mechanic just used it because thats what they had on the shelf, or maybe like me they had to change to that when something like an oil fitler sandwich plate was installed.

however I am pretty certain Z224 is not correct, factory fitment on any skyline including post 1998. They are off ca18 silvia, micra etc.

Thats great info guys, I appreciate it.

I have no AFM (Microtech ecu).

The guy pulled out his booklet and claimed Z442 filters are for 1998+ Rb25dets.. so the last of the R33's then R34s.

I'm hoping (as Duncan suggests) that its just the wrong filter currently on as the last filter change was done by a workshop.

I'll do an oil filter change this week, see how it goes with the Z442, might clear some things up

Forget the oil filter that's on there, any monkey could have grabbed a random one that threaded on and used it. I don't remember seeing a Z442 in the reference book, I have a series 2 and it definitely uses a Z145A filter.

I run a Z145A on my S2 motor however its not post 1998. interesting how the guy said it was for late models?

1998 was the last year of the R33.

This book lists RB25DET in two date ranges, 91-98 and 98-on. 91-98 is the R33 and uses a Z145A filter, 98 on is the R34 and uses a Z442 filter. The Z442 will be no good on your R33, the thread will be wrong.

Just to clarify that, Z224 has the right thread for all RBs, it is just physically smaller.

So it won't stuff anything, but the bigger the filter for the available space, the better

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      By sonicii · Posted

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????

      Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
