Whats the most cost effective solution for radiator/fans on an RB25 swap?

[RideZX6R]

I want something that will work all year round for me... I know it's gotta be slim.Altima fans won't work like on an SR if I understand right.So what will? What have you guys used with good luck that won't break the bank?Thanks

What mods (if any) have you done to your engine?

I got an S-14 radiator (for Free!) and used that + 16" SPAL pusher (~$150). If you do this, you need to upgrade your alternator (Quest 110a) because the fan draws around 25a. Work on some ducting and voila!

Oh yeah, stock RB25 with FMIC and 3" exhaust.

I have an S14 that I'm putting the motor into.I haven't even done the swap yet.I'm planning on buying everything I need first.I'll be doing an FMIC as well, it'll eventually be getting a GT35R, but not for a few months. I'll drive it on the stock T3 for a while.

I bought some 16 inch e-fan off of ebay, mounted to my S14 radiator and have never had a cooling issue. I've run this setup all summer and in stopped traffic. The fan, if I remember right cost me about $45 new.

wired it in as a pusher?

so ok ... whats all this stuff I read on Zilvia about the fans/rad having to be really slim then?

[s14_sport]

well its better to have your e-fans as pullers....thats why they say efans have to be really slim because since the RB engine is one big mofo there is hardly any space between the radiator and the front of the engine to fit fans. Using your fan(s) as pushers is not as efficient but having it mounted on the front of the radiator leaves you some room to have a really big fan. So it all depends on your setup.

About 1-1.5 inch clearance from the pulleys with slight modification of the upper radiator support.



I have heard many good things about the Altima Fan setup too.

S13 with RB26dett, with stock twinsI'm using a stock S13 radiator with two Hyundai puller fans. I have a hole cut in my front bumper.



I have no cooling issues for daily driving. If I start pushing the car for very long 30seconds or more I do start to heat up.

I am purchasing new coolant parts as we speak, but this set-up will get you by for quite a while.

Existing radiator $0Radiator hoses $152-12" Hyundai fans $20Water Temp Gauge $40

Being able to drive the car as-is, priceless.

Good to hear. As you can see... I'll be going the way of the RB as well

Well I want something that'll work in the long haul but not cost a billion dollars. Not something to "hold me over"
