well i always thought of da v/top mount coz of dat fact ur awayz getting ar in even if sideways + shorter pipes + more room for MASSIVE radiator nd twin fans (tripple fans ? :) )

but den again wudnt realy want 2 cut bonnet up nd access for engine wud be a lil bit limited

ok lets switch this thread up a bit... we in theory know that this wont work well due to the amount of heat and air blockage...

Now lets throw in the AC cooler... how would you fit that into the equation if removing it is not an option?? i was thinking of pairing the AC cooler and the radiator together on the bottom of the V-mount... with the cooler in front of the rad.

mount it underneath the radiator so that gets bashed before the radiator does :laugh:

ok final solution... sorry would have got pics but i forgot to take my camera.

but the run down is a comprimise and cost effective...

GTR intercooler mounted upsidown where the radiator sits, radiator mounted behind it (AC removed for other reasons) gotta see it to appreciate it, the piping is so short, everything is protected by the core support and all at almost no extra cost... ill try to mock it up again tommorow for pics... but i might have to wait till i get some parts from the US and complete the install...

actually it's quite scientific as to why intercooler belongs in front of rad. It's called counter current exchange in animals (which is where I learnt about it anyway) it's basically the optimum way to transfer heat between fluids. The underlying principles are well described here: http://en.wikipedia.org/wiki/Countercurrent_exchange

Shortening the length of the pipe will reduce lag, however you are sapping the IC of most of its efficiency, it is only cooling air around what? 40 degrees? as opposed to your radiator which is cooling water from around 80. You would basically reverse the counter current exchange.

basically what was said a page or two back... but thanks for the recap....

I'd like to see this new setup 4d-whore. Sounds cool.

If you WERE going to keep the aircon with a V mount, I would say it'd be best to put it right in front of the V mount. i.e.-

_

V

r

e

s

t

of

c

a

r

The air condenser isn't very hot after all, and due to it's size wouldn't block enough air to matter much at anything over 20-30kmh - maybe under it would make some difference however.

I think so long as air is being forced into each cooler properly with baffles/air dams it'll be ok. Without that I don't think it'd be anywhere near optimal efficiency. If you're not going v mount and you want that little extra you should try a small lip (like garden turf size) below the engine as well.

haha yeah its pretty thin but unfortuantly we had a conflict cause one system was R112 and the other was R134 or somthing... i wasnt to keen on keeping it anyways since it weighs like 70lbs... thats about 5 horses right there.. and it was just annoying i dont mind not having AC i told my jap friend that if he wants it he can transfer it himself haha... the japanese are pussy's when it comes to hot weather and rain...

i hate the cold myself...

they cut the entire core-support out of the car to do that... i was moving my dummie rad and core around and just couldnnt see any better way to do it then the setup i picked... vmount is more efficient but the cost changes a bit... but i think the response will be the same between the two

      Jacks that fit under GTR lips that can reach the subframe?

      You know how your car rolled through a fence in your last jacking escapade? Scissor jacks increase the likely hood of that sort of thing happening immensely!

      http://calfinn.com.au/product/1500kg-standard-trolley-jack-cj-2t-c/1500kg-standard-trolley-jack-cj-2t-c   I have this and fits under a S3 33 GTR with no issues. Purchased in 2009 and not one issue. It was $950 back then. Not cheap but something so important isn’t worth cheaping out on.

      Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?

      Intro/R33 owner

      By f00stx · Posted

      Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).

      Second time Skyline owner (R33 GTS-T and now a V36 370GT)

      Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).
