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

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
