  • Intercooler Upgrade

    After seeing Cross Country intercooler upgrade on Matty's 120, i gave them a call in regards to an upgrade on my 150, here is Jon's reply

    Hi Derek

    Thankyou for your enquiry mate.The 120 kit turned out pretty nice with some very good results. We havent done the 150 yet but we are itching to sink our teeth into it. We have had a good look at the OEM setup and believe it is hamperd quite severly by being behind the AC condensor and the cooler itself looks very restrictive. I would estimate a kit for this model will be a bit dearer than the 120 due to the large size of the cooler, however it may end up being the same price, around $1595. If you live in SA we would love to design a system on your vehicle and could probably work out a very good deal for you


    I look forward to hearing your thoughts


    Kind regards Jon

    If there are any 150 owners who are interested to get this done at Cross Country in Adelaide would be great, then there would be a kit i can get sent up to me, if not i might have to get it done next year when i drive down to see family.

    cheers Derek

    Gotta agree with the Roo, that seems a heck of a lot for what I would think would be not a huge gain, but then up there with a new mandrel bent exhaust I suppose so each to their own.
    Like everything the stock intercooler will be built to a price.
    On a positive good to see companies willing to give us some options over stock, this will mean that when the stocker fails (as it inevitably will) we will have options to replace.

      What i've seen people do on here with exhausts, put better flow thrus on and then chit it, but if a motor can't breath its limited. The intercooler on the 150 is restrictive and seeing the improvements on Matts 120 with it running to the front is impressive, the intercooler option too me is like part 1 of a series of mods to keep the engine running cool, better fuel economy, and more horse power.
      Its no different to a petrol engine more air/fuel mixture in and out= more power.

        I'm interested too see how it goes, would be great if they had a top mount intercooler upgrade for the 150

            Really? You want to un-do all the technical advancements put in by Toyota to overcome the issues of the 120 top mount. Interesting. Or are you suggesting adding a top mount in-line with the front mount?

              well it would would be good if they had the intercooler in front of the radiator

                Agreed that the factory intercooler is inadequate.
                A top mount would be a disaster.
                They are better than nothing, but never work great.

                  An observation on the front mount full width standard intercooler.

                  Using my scangauge to monitor the manifold intake air temp towing at speed on the highway up and down hills etc the difference between the ambient air temp and the intake air temp is generally no worse than 2 or 3 degrees C. It would be hard to improve on that.

                  In slow going, track and low range work it does get quite a bit worse though. I would have thought that the fan would be dragging enough air through the radiators to keep the intercooler temperature a bit lower. I guess the viscous fan is working uncoupled a lot of the time and the air flow is reduced.

                  Cheers

                    Is yours still stock at this stage, or chip exhaust etc?

                        Well, you could always cut a huge hole in the front grill/bumper region and stick a monster sized inter-cooler there just like those drifter goons with their nizpros.

                          In Singapore last month there was a generic Nissan thing with huge spoilers, wheels sticking outside the guards, no ground clearance etc etc. it also sported a truck sized intercooler mostly poking out of a gap hacked in the front bar. At the top of the windscreen was a sticker that on the left read NISMO and on the right some Japanese katakana characters. The katakana read "ricer". I chuckled.

                            I am surprised at how low those temp differences are.
                            I have data logged many times for various intercooler setups on various vehicles at work.
                            On an average front mount air to air setup most of the time we see temps go to 5 degrees above ambient before they even hit the intake of the Turbo, just from coming in through the intake tract in the engine bay area.
                            Then out of the turbo to front mount intercooler an average would be 80-100C (120-140C on bigger hills). Also the higher the boost level, the hotter the air.
                            Post air to air intercooler they are usually somewhere in the range of 10-20 degrees C above ambient still.
                            20-40C above ambient on bigger hills with heat soak through the cooler.
                            Things like ZD30 top mounts etc are way worse.
                            But any intercooler is still better than no intercooler.
                            Haven't data logged my own KZJ95R yet with the old top mount, but am ordering a gauge soon to permanently mount a probe in the intake tract and post intercooler.

                            Regards, Jason.

                              Hi Jason,

                              Interesting topic.

                              Not sure of the actual location of the Intake air sensor but the difference on highway is so consistent that I just subtract 2 to get the ambient air temp as shown on instrument panel. In the harder conditions I have seen 65C or more for intake.

                              The 150 front mount intercooler is full width and full height. A lot bigger than the top mount in my old 95. It is mounted between the water radiator and the Aircon condensor though.

                              Are you talking diesel or petrol turbo engines?

                              I had not thought much about any differences between the two. Yesterday I was in another car, petrol with frontmounted intercooler and was surprised how high the temps were. Going up hill, steep with lots of boost intake temp was about 45C, ambient about 20C, At crest of hill intake temp dropped to 38C or so. Then long down hill temp went up again into the 40's with no boost and full vacuum, strange I thought. Then level roadwith a bit of throttle, intake temps plummeted, well sort of down to 31C.

                              Then I thought about it what was happening. A petrol engine has a throttle valve, this controls the amount of air flowing through the intake. A Diesel normally does not and has virtually no restriction on airflow (hence no vacuum for power brakes). In the above example the temperature was also being affected by the amount of air flowing through the intake system. More airflow temps lower, less air flow temps higher. I suspect with lower volumes of air heat soak into the air from turbo and other engine bay components will have a greater effect.

                              Cheers
