Ok so pretty much I have an r33 s1 with an rb25de and I'm going for a fairly stealthy look so mostly factory bits, but since I'm new to turbos and what not I was wondering if anyone could explain to me a few things ( also I tried using the search but nothing I found was of use).

Firstly which lines on the turbo are water and which one is oil (already has the oil drain pipe) and where do they go to?

Secondly is it worth getting an aftermarket bov? I've read that the standard are a bit dodgy. And if aftermarket what is better between plumback and vent to atmosphere

And last thing for now I just want some recommendations for what has worked well for others, spark plugs, panel filters, fuel pumps and wide band sensors.Thanks, nathan

Try here:

Loads of information and most of your questions answered.

Also, be prepared for everyone to tell you to "just buy a GTST"

If your turbo has the oil drain fitted, the oil feed is directly opposite it on the other side, ie. top of the turbo when it's mounted in the engine bay. (provided it's a stocker)

There is a bung on the side of the block for the water and oil feed, you know which is which by what runs out when you remove them. The water return and oil return on most NA engines isn't there, bit of info in that^ thread about the returns.

Stock BOV in good condition is fine, don't go atmo unless you're running aftermarket engine management.

Upgrade your plugs and coils, again read the thread for types, gaps etc.

Stock panel filter and airbox will work with a custom pipe from the airbox to the turbo inlet, or get a GTST airbox.

Fuel pump will need upgrading, again in the thread.

Wide band sensor? For what?

Hope that helps. thumbsup.gif

      Question about BoV on RB25DET NEO

      By GTSBoy · Posted

      Oh, I also meant to say that it is possible to use a venting BOV and restrict its outlet down so that it does vent enough to prevent the sututu, but vents slowly enough that the AFM doesn't see all the air at once and makes it easier to avoid stalling.

      I'll go talk to my bank manager. Either that or my nearest western Sydney drug baron.

      Question about BoV on RB25DET NEO

      By GTSBoy · Posted

      Driveability will be about the same with either externally venting BOV, or no BOV at all. Perhaps worse one way than the other, with me thinking that the definitely more flow going through the AFM through a venting BOV more likely to cause rich stalls than the perhaps more flow that the AFM might read on reversion. There is no such thing as "turbo damage" from not having a BOV at stock, or even quite a lot higher than stock, power levels. You need a big turbo with a lot of mass spinning hard getting a horrible slowdown from a slammed shut throttle before there is anything like the shaft loads required to damage things. Not an issue on small turbos. The ONLY 2 reasons that Nissan put a recirc valve onto the RB were: It is a bypass valve. It is open when under vacuum. When not on boost, it bypasses intake air forward around the compressor, which unloads the compressor, allowing the turbine to sping more freely, making the whole lot a bit more efficient when just puddling around. Throttle response should also be faster via the shorter, smaller diameter BOV pipe (when in NA, ie before the BOV closes and boost is building) which is nicer for driveability. Emissions. The reversion causes CO pulses. Eliminate the reversion (or at least, keep it away from the AFM) and you don't get that. The stalling/driveability aspect could have been tuned around, as shown one example of by dose above, if Nissan hadn't put a recirc valve on. Many many turbo engines before the RB had no BOV. They did not stall. See the RB30 turbo as an example. Nistune is definitely better than just stock ECU. It allows you to access and change things that are not excellent on the stock setup, and allows you to do mods like put decent injectors in, relocate the AFM, put a bigger turbo or even cams, etc, on, change to coil swith completely different swell needs, etc etc. All the things that you might need or want to do 25 years after the car was new. Aftermarket replacement ECU is obviously better again, because it gives you even more freedom from the constraints of the stock ECU. I won't be needing to go any further than Nistune though, for the new turbo in the 250ish rwkW region I'm going to, with big injectors, and most other things being stockish.
