hey guys... i was just wonderin if anyone has the know how on how to replace radiator fans in a rb20det r32...

mine is pretty much cracked, nearly all the way thru so it could potentially fly off whenever it gives way... sought of what needs to be done to replace the fan

also... i was wondering if anyone knows how to change how the fan sort of works... cause the fan is nearly always on when u accellerate and it makes my car sound really bad... and i was told it can give it a decent power gain when u change to something like on when it needs to be on and not always on...

cheers guys

There should be 4 10mm nuts on the fan, remove them, and your fan should kinda slide off, but you will need a little manouvering to take it out from the shroud without demolishing your radiator. I did mine when i was installing cooler piping on my 32, its easy to do.

Umm the radiator fan is a clutch type. If you want to change it so u can turn it on and off by a switch inside the car, youd have to replace it with electric fans i beleive. Unless someone knows otherwise?

Oh and if its making a noise while accelerating other than the fact your fan is cracked, you should possibly check that your belt is tight.

Hope that helps :D

by the sounds of it the fan clutch might be siezed and thats why its noisey. this will also cause the fan to crack due to overspeeding it, make sure you change it soon, or else it will become a bonnet emblem!!

hey thnx guys... ill give it a shot after i go find a fan...

but yer i think the belts are fine... they dont seem to be squeeking... but its the fan that comes on everytime i accellerate... apparently u can get a timing system in the engine bay that controlls the fan... a friend has done it but didnt explain it so i gotta whip him about it... he has a Lancer turbo so he did it to his...

your mates lancer being fwd will have thermo fan/s.

he probably has a relay hooked up to his ignition and a thermo switch that supplies it with power once the engine (coolant) reaches a certain temperature.

would definitely change your fan asap as my mate's (rb25) went through his radiator. wasn't fun.

there is an ongoing debate as to whether a clutch/engine fan is better/worse than a thermo/electric fan setup.

i personally use two 12in thermo fans run through a relay using the stock radiator temp sensor.

      Well it wasn't as easy as I thought.... and it also wasn't in my original manual which I did end up finding. They discuss the process in the Nismo catalogue though and it requires slight machining. Page 145.  NISMO PARTS CATALOGUE 2020

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I'm an idiot, my intercooler is rated for 1000hp. I had clicked on the wrong product. Knowing the delta P would be nice, but I'm doubtful I'll do it. Now as for an EMAP, that would be great and I'll get around to it eventually but from my findings in my last post, I'm considering a turbo swap now.

      You sir, big win tonight. Precision never supplied compressor maps in the past and Idk when they started, but it seems they only offer for a few of the older gen2's which is exactly what I have. I punched in some numbers and seem to have gone with the wrong turbo. 600-700whp isn't in the most efficient area and is close to the choke line. 800whp is well off the map. Punching the numbers into a 68mm gen2 turbo map is bang on in the center. Here I was thinking going smaller would shift the power band down, but in reality it would just make it so much worst due to my rev limit. I would have never thought.

      Increasing overlap will bring the torque down earlier (and make your idle sound sick lol). Worth a shot (if you dyno time) to experience a bit (providing you are confident your valves won't kiss your pistons). Is to just take off 5 degrees across the boosted area of the map, and then retard the exhaust cam let's say, 3 degrees at a time and then overlay all the runs with VCT on all the way and VCT off as soon as you make positive pressure. Ideally you would have a total of 6x overlays to looks at 0 exhaust & VCT off once manifold pressure is +ve 0 exhaust & VCT on all the way -5 exhaust & VCT off once manifold pressure is +ve -5 exhaust & VCT on all the way -10 exhaust & VCT off once manifold pressure is +ve -10 exhaust & VCT on all the way Just leave your O2 wideband closed loop on for all of the boost area & RPM, and hopefully there isn't too much fuel correction needed and the Haltech is fast enough to compensate (I do this, then apply the correction to the main table). Getting that overlay data should give you a good indication of what to aim for.

      iPad gauge cluster

      So, my main limitation here is that the car does not have an oil pressure sensor by default, just a switch. As part of my tune I bought an oil pressure sensor upgrade so I now have access to oil pressure levels and logging rather than just the boolean behaviour of the switch but this means I need to use the tuning app to display this value. So, this rules out using any other app on the iPad. The app will also flash when pressure drops which is a nice feature. I have replaced the centre screen with an Android one, which is awesome for Android Auto, but I think it might be too far away and out of my line of sight. I might add some gauges to it this weekend and just see. I guess if its just temp and oil pressure I can make them massive! 🤣
