Can someone let me know if there is a price diff between ISO and IS Copper....

Is that to say, if you drive to the snow, once, your car will die?

I occasionally visit skiing resorts....

The ISO kit comes with a valve that you open when the temperature is really cold (but subsequently reduces the benefit of the ISO spacer). It certainly won't kill you car. The main difference is the copper kit doesn't need this valve.

Unless you live in the snow I wouldn't worry about it.

The Motordyne has consistently better reviews, especially the ISO version.

I read that although skunk2 may be easier to install but skunk2 spacer is 5/8" instead of MD which is available in 5/16" or 1/2".

since the skunk2 is higher than 1/2" with the engine cover on it actually rubs the bonnet a little bit... fine if you want to leave the engine cover off but you may get signs of scrubbings on your plastic engine cover.

So to make sure i understand correctly rs73, after the install of the plenum, skun2 or MD, you will be able to place the cover on, but it will scrub?

Or is only an issue with the Skunk2?

I'd like to keep the cover.... but if the trade off is HP, happy to rid it.

The reason I'm going with the ISO Copper version is that it does all the things that the ISO thermal version does but does not need the CCV. Instead it has a copper plating to install on the throttle body. The CCV requires you to cut one of your engine lines to install and if you are going into snowy conditions you need to open the value to let hot air into the throttle body so it doesn't freeze. The copper version with is install and forget. Also means it can be fully removed without leaving any trace behind.

EDIT:

How important is it to install the ccv. i live in an area where it doesn't get that cold. should i install it and leave it closed?

Copper Iso Thermal is a premium set and forget component that can be used in place of the Coolant Control Valve (CCV). It doesn't matter how hot or cold the weather is, you don't have to adjust a valve based on the season or ambient temperatures. Install it and the throttle body remains heated while the plenum continues to remain thermally isolated. Keeping the throttle body heated prevents ice formation on the throttle body butterfly valve when driving in cold weather. If it snows or gets really cold in your area, use the Copper Iso Thermal so your engine can take full advantage of the cold air you are driving in.

Its not necessary to install the CCV but it is better if you do. Iso Thermal does not make HP but it does prevent the loss of it. Its good for about 1-2 HP by preventing excessive plenum heat soak as your engine becomes hot. And yes, you will generally leave the CCV closed. Iso Thermal or Copper Iso Thermal is beneficial no matter how hot or cold it gets in your area.

I really want one of these but I cannot see anywhere, other than the manufacturers website, a before and after dyno run. If anyone can show me a 10-12 horse power gain, I'd be in

Cheers

Geoff

lolz.. the group buy is going to end VERY soon, payment are being gathered and order will be put soon, i think..

IF THERE IS really a 10horse power gain, i m guessing some ecu mod on it..

as usual, any mod to reach its full potential, ecu has to be mod/tuned..

anyone can correct me if i m wrong, coz i just started learning all these stuff as well..

I've read a few threads which say otherwise, but cbf digging them up. By most accounts, this is acknowledged as one of the best n/a mods for a 350z/v35.

Anyway we've got enough takers, so up to you.

    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
