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.

      Rusty roof repair

      By Kinkstaah · Posted

      Nah that is not actually a lot. Just painting my GTR frontend and the little bits to make sideskirts/nismo flare pieces work correctly/fit on the sedan/mount up correctly came to about $7000. Is it a lot? Sure. None of this is economical. Economy would be shelling the car and buying a 2010 Corolla to commute in. The perspective of all of this is different.

      I don't see any issues here. I've been saying all along this is a big job, the price reflects that.  When the car comes back perfect I'm sure it will feel like money well spent.

      Remember, take original quote. Double it. Then add a bit more. It's how any project goes.

      Rusty roof repair

      By PranK · Posted

      So, I started this repair and got as far as "fixing" the holes with some fibreglass. God all those years working on boats came back quickly. I decided I'd reach out to some rust guys just to see what they would say about it. I came across a guy about 40 mins away and went to see him. He said the windscreen needs to come out, that there might be some more bits around the windscreen and he'd quote them at the time. But his quote was $300 to remove and replace windscreen and $3k for the damage he can see. He said he could respray the roof for $1200 and the bonnet for another $800 (somebody has previously rattle canned it, its horrendous). This is $5300 + any small additional bits. It's a lot, I get that and the name of one of my fave youtube channels 'Not Economically Viable' comes to mind.  I'm not being financially rational, but I've taken him up on the quote. He's opening a new shop in November with more room, so we're waiting for that. I'll leave the currently missing headliner out until then. I'm looking forward to it being fixed and having the paint looking nice again (lots of clear coat issues on the roof too). / flame suit on.
