Hello guys,

I have been reading through many threads on little ways to get increased performance from a stock cooler a skyline.

There are many theories including removing panals etc. I thought we should put all the ideas on a single thread.

If you have any great ideas for stock cooler performance lets hear them!

For Performance?

Throw it out.

For a small upgrade, water spray is the only really worthwhile thing

cost vs effort vs result that i could think of.

Moving it to the front & re-piping it is useless unless you can do it in your spare time.

Paying for it to be done is a waste.

Even though your paying for it with your own time though really when you think about it.

well i was told to take the plastic cover from the passengers wheel arch off so help the flow. So i did. Dunno if it makes a difference. I guess u could make up a plastic scoop of some sort to grab the air and direct it through the cooler. S15's i know of have this system, maybe something to think about. But yeah i dont think there is much u could do. Maybe the most effective thing to do would be unbolt it and clean it out with degreaser or something and let it dry in the sun. Get the oil film outta it

I always thought if u attached some good sized heatsinks to the outside of the intercooler that may help dissipate the heat that it generates a bit? Very ghetto mod though, but wonder if it would work? Works on a CPU :worship:

The only way it can perform better is by improving the flow to the core and adding a water spray.

Even than it is a flow restriction once the boost in increased to around 12psi so not really worth the time to play with if you are running muchover stock boost.

Why not plumb oil through it and use it as an oil cooler, then mount a nice big front mount and plumb it up to the turbo and inlet manifold.

Alternatively fill the std intercooler with cement and stich a piece of chain into in before it sets (should make a great boat anchor)

- remove and clean out thoroughly with some sort of degreaser

- Cut a hole in the perforated plastic panel behind it (removing it entirely makes the front bar a little less stable)

- make up a plastic surround to channel (force) all of the air through the core.

- definitely don't mount it at the front, waste of time and you'd look like an idiot :worship:, also it will actually get better airflow in the stock pposition where air can flow "through it" and out the back

- as mentioned, a good upgrade (& cheap) is an r34 gtt intercooler.

the panel at the back and the ducting is a good idea. The cooler is pretty crappy in design, it's size isn't too bad tho'. The R34 intercooler is slightly larger but suffers from the same crappy end tank design and core, should work a little better all the same.

instead of water spray, why not mount a small electric fan behind it to suck air through (ie a fan from a motorbike)... cheap although probably most effective at helping the intercooler cool off ffrom heat soak, rather than reducing the intake temp

i agree wholeheartedly with the above however, the best material for making a duct to surround the IC is 1mm aluminium sheeting. it is quite easy to work with & cheap when you ask for offcuts.

Speaking as someone with no idea; this one sounds good. Anyone else think so?

No :D

The fan would push less air through the core than the airflow at 60kph

Great when sitting in traffic but then the fan would be a restriction once you start moving again :Oops:

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
