R32 GTR - Aftermarket Radiators and Factory Shorud

Hi All, 

 

Have been looking around and it seems some of those with aftermarket radiators have hacked up/no shrouds and others have them intact. Who here has a aftermarket rad with a factory shroud that fits?

Koyo radiator, factory fan and shroud. No touch. I also installed new radiator bushings and pulled them all the way forward on install. Worn bushings could have caused mine to hit. Another option would be to machine some offest bushings pulling the radiator further forward

sometimes that chopping etc of the shroud/ rad from the fan comes from worn / broken engine mounts when the car brakes etc the engine can move forward hence closing the gap / changing the alignment of everything... been there !

Engine mounts maybe.  In my case and at least a couple of others I've seen it's simply the radiator getting sucked back towards the engine by the engine fan.  It doesn't seem to happen with stock radiators, so maybe they are just too thin (to take up the room) and too thin (to put up enough resistance to airflow) to move far enough against the rad mounts.

 

I just jammed some more rubber into my upper mounts (on the back side) to pre-load them and prevent it moving back.....well, after it has already sliced a line through my shroud!

nope, don't like their welds :)

but they're massive up your way, Ryan Tuerck uses them... if you're bored... go compare the welds on a Plazmaman FMIC and a Mishimoto :)

I've got a cefiro, so not a gtr. But, 

 

I run a 52mm rad with the stock shroud and fan. Had a few drama's with the fan hitting the shroud.

I machined some new lower bushes out of nylon, and made new brackets for the top with no bush.

 

Haven't had a issue since. Car is used for drifting so gets a bit of a thrashing. Tried twin thermo's early on, and they were shit.

Granted, they weren't expensive ones, but stock fan and shroud is simple, and it works.

 

Oh and don't underestimate how much the stock fans flex, I had a Z32 fan (greater offset, but had one lying around) on after the thermo's shat themselves , had a decent 15mm gap fan to rad and it still grabbed the radiator at high rpm.

What is the thickness of factory radiator?  Mishimoto is only 32mm so it should have fewer clearance issues, and 10% cheaper than Koyo here.  They also have great lifetime warranty that even covers collision.

well i personally dont, but hey each to there own....

only if done right.. and 9/10 times it is done wrong...

Most owners just hard wire their fans OR use shitty fan controllers that turn off and on constantly like a strobe light.. followed by those who just hook it up to their OEM overheat fan relay/thermoswitch.

You need a proper fan controller either a standalone unit OR through your car's aftermarket ECU to set OFF and ON points followed by some form of hysteresis - only then would that be consider an appropriate installation.

    • @GTSBoy This method was able to get readings of -10 to -2, so it looks like its monitoring.  Now I need to figure out why the vacuum on the line provided isn't alternating with manifold pressure.  I went with 2 lines that an RB25 tuner recommended but I'll get a longer hose and try directly off the back of the manifold.  He may have been used to OEM intake setups while I have a DBW setup that removed the MAF and IACV.  
    • I work at a car detailing and tinting shop called Quark which gets all manner of German cars in usually (mainly due to a contract with Mercedes Benz Kita Osaka, BMW Nishinomiya and others) but every once in a while something special comes in, like a fully restored 1972 HS30 Nissan Fairlady 240ZG... The shop owner had immediately started applying film to the windows as soon as it was in the shop so the interior was completely covered in towels and plastic sheets. But I could get a few photos of the engine bay which was restored like new. Such an amazing car to see in pristine condition in Japan these days.  
    • Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.
    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
