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

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.

      What should I do next to hold the head on

      By Gareth87 · Posted

      Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.

      Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...

      Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
