Hi Guys

Can anyone shed some like for me on the late 98 Series 2 RB25det Stagea RS-Four? Brought one being told it was a Neo. Picked it up started stripping it off to put it in my S13. The Cas is the Black plastic cas, the loom is the grey plug ecu. I thought it was a Neo from that, but further looking into it it had the side feed injectors, the 3 bolt IAC valve, the small TB. Which had me instantly suspicious about it being a Neo.

Looking around found 2 pictures of Late model RS4's with these motors. Does anyone else know anything more about them?

My guess is a Series 2 motor internally and intake and exhaust sides. But whats the deal with the ecu now? would i use the R34 GTT pinout for the grey plug ECU?

Just wanting to know this as i plan on hard wiring the motor to the battery via a switch and fuse panel.

Both the stagea's in the pictures are s1 stagea's so they have s2 rb25det not the neo model , s2 stages 98 onwards "the ones with the spot lights in the grill have neo engines , the s1 computer is untuneable unless you run a stand alone or piggy back system , you could change the cas and comp over to a neo one , then you could run nisstune , but I'd say ATM you've just got a s2 rb25det

sorry i must or worded myself wrong. i've worked out its a S2 rb25det from a S1 Stagea. Is it common for these to have a grey plug and not the normal blue plug like the R33 RB25det's? Do they share the auto trans ecu in there?

I'm not planning on tuning this motor any time soon, will be left as it is just in a track hack S13. I just want a ecu pin out i can figure out how im going to rewire the loom up to power and switches.

is this the pin out i want, from this post here, http://www.skylinesaustralia.com/forums/topic/406866-ecu-tuning-for-s1-stagea-do-we-have-a-solution-yet/?p=6516626

Yes that will do it. if you are running it with a manual box you can always swap it for a plug in Link later.

Yes Link make plug in ecus for Nissans, evos, Toyotas etc. They also make a wire in version which can be adapted to almost anything. I have a G4 plug in (the R34 version to suit the Stagea plug since I have a manual conversion). I think the only mod necessary was a wire from the TPS to enable the Atessa ( I didn't install it - the tuner did).

Didn't think links where full plug in ???

      R32 GTR clutch master cylinder adapters

      I replaced the whole clutch line with the chase bays braided hose, I think it removes that loop, is it the short hose that comes immediately off the slave or is there a drawing in the manual to find what you’re referring to? It was just re-bled when I upgraded to the nismo slave, old slave worked fine but I thought that might help, didn’t change a thing. It’s like the first half of the pedal is pushing air and then when it finally actuates the master the friction zone is tiny. Makes it practically impossible to launch the car

      Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.
