Hey guys,

Well it comes the time, when we had to trim my clutch fan to make room for the cooler piping, and now ive noticed the temp go up slighty not too much tough. Ive decided to put twin thermos from a AU in, and would like peoples susgestions, ive looked on the forums and overall people are happy with thermo fans, but i would like to know what the best would be for a r34 rb25det neo6 engine. Has anyone done it and has it fit? what are the downsides.

BTW when the air con is on the temp jumps threw the roof i need this fixed guys!!! please help me out.

Cheers guys! any one who has done it to a r34 i would really like to hear from you ;)

i honestly think your wasting your time with twin thermo fan setup ...

my first suggestion would be to get your original radiator modified to twin core for $350 or less and then if that aint enough i would get a low temp thermostat and you shouldnt have any troubles even on track days....

cheers

i do lots of rb conversions into silvias and i use 2 12in davis craig fans on a r32 gtst radiator and i have never had any overheating problems

i have then hooked up on a custom thermo fan relays with a custom thermo switch (which btw plugs straight in to the r32 overtemp thermo switch ) the thermos are switched on at 85.c

A low temp thermostat should fix your prob at the moment, i went two 12" davis craig fans on my 180 with a temp switch and for all the effort and money i should have just kept the clutch fan with a low temp thermostat.

i would like to know about this also. after installing my fmic on a bit of an angle and moving my horns up to the only place catching cold air for the radiator the car sometimes heats up a bit when its hot.

my clutch fan still seems ok and ive replaced the thermostat with a standard one.

which thermostat is lower in temp and suits the r32? i used the one listed for the rb30 r31 skyline one.

Before we all go suggesting to this person a low temp thermostat... I think someone should outline the negatives of getting one installed as well.

I have one from ARC; yet to put it in because I've heard it has negative aspects which is not ideal for street applications.

Can't remember all of them but one of them was longer warm up times???

well thats actually wrong because it doesnt open up untill it get's to that temp so when it get to 65 or 70 depends which thermostat u get then it will open up fully ...eg: your stuck at lights your temp goes up and then your thermo opens up to cool the engine..warm up is not an issue as the car just sits there and warms up pretty fast .. but i suggest u do your radiator first and then go from there..

Hi, I work for a radiator shop in New Zealand, We do cleanouts/alloy race rads/oil coolers etc.. (I manufacture race rads/intercoolers)

I would recommend getting your radiator rodded out (cleaned out) and a new top tank put on. I can't say if this will fix your temp problem, but go to the most obvious problem first, maybe your radiator is actually blocked..

I've pulled apart 2000 model cars and they have been as blocked as they can be..

Just a thought.

I don't think a low temp thermostat will help much. It might delay the overheating slightly but it's inevitible. Your radiator and fans as they are can only do so much cooling.

I would replace the radiator if I was you but if you want to go thermo then go for one 16" rather than two 12". It pulls a lot more air. Supercrap have them for about $90 at the moment. Dunno how good they are though.

      Quieter performance exhausts (or muffler add-on options)

      Nope.    Grab a varex and turn it down as you get close to home, win win?

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
