has anyone here had any experience using a half size (width) alloy radiator with their skyline? I'm considering a different intercooler/radiator setup and the half width radiator frees up more room in the engine bay.

I have seen these being used on turbocharged hondas running lots of power, mitsi evo's and other fwd cars to fit large turbos.

they are thicker than factory radiators and aluminium dual/triple cores? the cooling ability should be sufficient????

Hi, I actually make alunimium radiators for a job, mainly for performance cars..

I would *not* recommend this, stick to a front mount setup or if you want to go something different, go water to air..

nope, lots of highly modified hondas run half size radiators. they come factory with a half width radiator, so upgrade to an alloy thicker version. allows fitment of a large turbo.

ive seen the setup on evo's as well.

will have a search tonight for some examples.

surely if I use a core twice a thick as a standard radiator and made from a more heat conductive material, i can have the same cooling efficiency as a full width thin factory radiator?

I've seen them on a skyline but the only reason it was running one was it ran on alcohol which runs a lot cooler. they wouldn't work on a large engine car because they just don't have the cooling capacity for hot days in traffic. if you we're only going to use the car as a track car with sustained high speeds and good airflow over the core then maybe, they are not suited for everyday skylines

lots running 300fwkw+ daily drivers.

id imagine the same heat is produced from the 6cyl vs the 4cyl, since heat is generated by fuel combusting. so same heat output if youre making say 300hp whether it be from a 6cyl 2.5 or 4cl 1.8.

What exactly do you need the room for?

You say it will free up space, sure. But it will only free up a bit on one side.

Then you will fill the other side up with a thicker radiator + thermo fan.

Civics come with a half size standard, so do the CTR's.

Integras have full size ones, and people do change to thicker half sized ones in them too and dont have issues. (Turbo setup wise)

I dont see why it wouldnt work, but it seems pointless. You'd probly want to make up some sort of shrouding to direct the air towards it too.

im just suggesting a different idea and seeing what peoples opinions are.

thats cool if you think its 'pedantic'

shorter intercooler piping and better flow sounds like advantages which are worth the effort if a half width alloy radiator will be enough for engine cooling.

Well it is really.

If it was so important dont you think someone else would have tried it? Like a Japanese tuner?

How exactly would the piping be shorter anyway? It still has to travel to the same place. All your doing is having a smaller core to fill. So you would actually have more piping really. To cover the distance that the core didnt take up?

airflow through the radiator and intercooler.

radiator behind intercooler gets warm air, and less because of the ic.

ic gets less flow because of the radiator blocking air behind it etc

Mate my I/C sits directly infront of my cooler, its basically the same size too...

And my temps on the street are 69-72 degree's. There is no problem with airflow or cooling of anything. Your worrying about nothing.

I highly doubt you'll get a cooler that will work, in such a small space. Chase power, you need a nice core and it wont fit there

Sounds like a lot of dicking around + cash spent, for a f**k all gain.

Stock or alloy aftermarket radiator + FMIC = a reliable package that looks as good as it performs.

If you want better cooling - try ducting the radiator and intercooler with thick plastic sheets.

Alternatively, you can for a V-Mount or Predator style setup as pictured:

agreed.

considering its only got a thermo, and a small one at that... its going to be horrid with some of the worst heatsoak in traffic anyone could imagine.

The car would have to be a track car, with lots of speed, for that to work remotely well IMO.

My setup is very similar, except my rad/IC is much larger, there is a slightly bigger gap... and im still running the factory clutch fan.

All that comes in ~70 degrees driving, upto 74-75 in traffic at best on a 25 degree day :)

If it worked well having the smaller intercooler don't you think Nissan would be doing it? that's right they aren't because it isn't efficient. as we all know about car manufactures if they can build something cheaper that works the same they will

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      S1 rb25/s14 starting problem

      By MBS206 · Posted

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
