Took the words right out of my mouth, I have the same fans and shroud, and he's not lying when he says they sound like a hurricane, cause they really do.
I'm running
Mishimoto radiator
Mishimoto hoses
Isis duel electric fans and shroud (same ones as pictured)
Stock thermostat
Also I have a PBM HMIC so I get more direct air to my radiator.
No overheating or high engine temp issues whatsoever!

running oem clutch fan on my dd rb25 s14, no shroud, havent had the luck of finding one, maybe will have to build my own, anyway, never once overheated, im even running a stock thermostat, and that's in the texas' heat where we see 100's daily during summer

My new SR build runs too cool. It hovers at 130 degrees and only gets up to 150 when driven hard for a prolonged amount of time. I am changing out the thermostat to ensure that it isn't stuck open. My oil never gets to or above 140 degrees. I have a DIF fan controller I have yet to install. I suspect that the thermostat has a pin-hole drilled in it to ensure that it always flows a small amount of fluid, which helps it stay cool, and I will confirm this in the next couple days after the thermostat is swapped for a Mishimoto unit.

What part of Texas?

GKTech Replacement Engine fan - Nissan S13/S14/S15 SR20DET

This looks good. It's supposed to be better than an RB25 fan.

This is on my next to buy list.

Proper ducting would be the best cooling mod... People running around without the lower splash guard complaint of over heating issues, need to fab or reinstall theirs.

I'd love to see some pics of some under guards that everyone has built? I'm thinking about doing a PBM one, but I'm honestly not sure if its worth it, or if I can built one better. Would be cool to get some ideas based on what everyone else has done.

I've been thinking about the same exact thing.

For the people who run the Isis fan and shroud set up,
What are you temps just normal driving?

[PandahZ650]

For those overheating with a stock/oem thermostat should definitely try running a lower temp thermostat, or even no thermostat. All these big radiators, fans, ducting, etc. can only do so much if the thermostat isn't opening up at a low enough temp. for your motor.

nobody mentioned a vented hood. sucking in air is all nice, but it's gotta go somewhere... i noticed improved temps on my previous car with a vented hood... i'm gonna make a mold for one for the sx as soon as im finished with more pressing stuff.

my setup:
driftworks aluminium rad
samco hoses
oem stat
dual e fans, nissan , i don't remember what car

havent installed the rad yet, the car now has a radiator what the previous guy says its from an s14, but it seems tiny to me, like 2cm thick, single core.

have you not read this thread at all? no thermostat can result in coolant flowing too quicly through the radiator to cool the liquid effieciently..... dont offer your 2 cents if you dont know what your talking about please....

A couple of my friends have used no thermostat/drilled out thermostat at the track and their temps were fine. So i guess my own two eyes and previous posts in this thread are not good enough to verify that it can work in some situations depending on your setup.

I'm not trying to get in an argument here but I was trying suggest that those with oem thermostat that are overheating/high temps could try to run a lower temp thermostat to cool the temps with a secondary less recommended choice of a drilled out/no thermostat, my intentions of the sentence was to focus mainly on running a lower temp thermostat. I guess i just worded it badly. Just offering my thoughts and opinions on what i think is one of the best cooling mods(opinionated topic). Just my opinion and 2c , take it or leave it.

Swirl pot and expansion tank. The radiator i was gonna use was a 3 pass MR2 Radiator



Got the idea from this.

[PeaceOnesxWai]

This is pretty cool, uses 4 radiators (welded L-Shape) and rear mounted.. high mounted expansion tank

This thing probably uses 2 gallons of coolant

[Te37]

Where is everybody getting your water temp reading from? I run in the 180-200 range, but my temp gauge is on the water neck output. Is that too hot?

My car uses 2.5gals of coolant and all I have is a Koyo radiator on an SR20VET...

Mine is on the coolant outlet and I saw temps between 195-220ish... SR's tend to run hot and I've heard of dudes running 240* while tracking their car.

which is a better fan? altima dual fans or a single ford taurus?

does the ford fan blow harder?

Did you not read the CFM's posted in the first post of that fan thread? The Taurus fan on low(2500CFM's) flows more than the Altima fan on high(2200CFM's). So yes, it "blows" harder.
