Whirring noise from a/c

Hey guys, a whirring noise has just started coming from the air con, sounds like a lawnmower in my dash. Well, maybe not that loud :P . Does this mean the a/c motor is on the way out, any ideas on how much it would cost to replace this, or does the whole a/c unit need to be replaced? I imagine it won't be cheap either way.

Cheers.

i had the same problem, had paper (wtf!) caught in the fan, it was easy to get out though... (mine is a R33)

just remove the kick panel on the passenger side footwell left wall, remove the ECU, unscrew the 3 screws holding the black cylinder looking thing up into the dashboard, and gently pull it out, it houses the fan.. clear it out and stick it all back in :D 10 minute job, and i put of with the crappy noise for months!

good luck!

does your aircon work popperly? producing cold and so on.

could be the a/c compressor that is getting weared out. so remove the belts to get to a/c compressor belt and remove it too.

then turn it by hand it should turn smoothly with out any odd sound and you should also press and pull on the pulley in all directions, you are looking for clonks and wiggling. if there are any your compressor needs to be changed

yep, sounds exactly like what mine has been doing, on really hot days it would struggle to keep the car cool though and i have to turn it off after a while and back on again and it starts cooling.THis was happening for about two weeks and on friday it blew up!! It started blowing hot air, then there was a burning smell and a bit of smoke from under the bonnet, I turned off and the smoke and shit went away. So now I'm without air con and it's really ****en hot. Hope this can be fixed easily. Hope yours doesn't blow up!!

i got the shits with mine and bought a second hand compressor anyway. cost me $200 but its worth it. didnt have a chance to fit it though, front brakes locked up at 100km/h and i hit a parked car, but hey, atleast now that i got the motor out, makes the compressor swap easy :P

      That's a given!  Bit hard to powdercoat it properly without removing them! 😁

      No detail on compressor or turbine sizes, which doesn't help with housing size selection with that kit. However, from SR20DET mucking about and money torching perspective, a GTX2860R Gen 2 w/ 0.64 (46mm inducer) will do ~260kW on E85 about 1.5bar of boost. All in before 3000pm, which cause a gearbox to shatter. Now imagine the same turbo, on a modern motor with an extra 0.5L of displacement, and heaps of cam timing adjustability (not an on/off affair like the Nissan shit boxes). If this was my car (which I would never own or consider buying, ever!), I would go for a nice twin scroll setup, and a G30-660. Gates plumbed back, no silly shit. Lean on the cam timing, big displacement to create a flat-ish torque curve.

      Do you plan on using 98 or e85?

      This should be pretty easy. 200rwkW is just about the max power out of an RB25 stock turbo. So, 12ish psi on a 2.5L. That boost limited mainly by the prospect of seeing the turbine in the cat after the smoke show. A steel wheeled equivalent would likely happily do ~220rwkW at something like 17 psi, where it would probably be bumping into the usual limits of such a sized turbo. These things have like a .48 rear. You will not need the 0.86 rear. The 0.64 will be fine. In fact, if you were looking at various mid-200rwkW options for RBs, most of them would be in a 0.64 rear. So, I think you will definitely want to be no bigger than that for a same sized but probably even more efficient (at making power) modern engine.
