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:

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
