guys just quickly, iv got an R33 S1 GTST, now the stock thermal fan at the front, wen does it kick in or does it. Iv heard it supposed to kick in wen the A/C is turned on, but it is NOT activated by temperature levels. Mine doesn't activate wen i turn the a/c on at all, does this mean its not working???

let me know ur thoughts

cheers

it will only switch on when your a/c is on and you go ever a certain engine temp. the temp probe is the one screwed into the bottom of your radiator. you could check to see if the probe is plugged in. alternatively if you have or know anyone that has a consult cable and software you can do an active test where you switch it on through that.

yeah i believe it will come on with aircon when required.

on a side note, what happens when you put a fmic in front of that temp probe?

does it see temps as hotter and therefore turn on more readily? any adverse affects?

nah that a different probe. the one your taking about is the outside air temp. there is one screwed into the bottom of the radiator, so that when the coolant/engine temp gets to hot it switches on. the only time i've ever heard the fan come on was in the middle of summer and in really heavy city traffic.

so that thermo fan actually kicks in to control engine temps???

i thought it was purely for the aircon

thanks fellas.

to comment i would've assumed it should kick in at high engine temps like other cars.

but like mentioned above i was told purely for aircon. so even if the aircon is on it wont kick in until a certain temp??

these cars must hav good cooling...!!

yeah..thatur a/c fan..

does ur clutch fa come on??

if not...,thats wat i'll be worried about...

but for ur question lik a few people mention it should come o wen u press ur air-con...dependin on how hot it is aswel..if its required..

another question not related...

how people hear have done a clutch fan conversion to a thermo fan on a r33 skyline??

I will be converting to a 16" thermo fan as part of my RB30DET conversion. Fan will be spaced approx 30-40mm off the radiator and use the stock shroud. Fan opperation will be speed controlled using a picaxe micro controller and stand-alone temperature probe.

The whole process has been halted at the moment due to the x-mas break though...

you'd be better off using AU falcon thermo's and shroud and simply attach to your radiator and seal the edges.

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
